COGENERATION: WHAT IS
Cogeneration (CHP - Combined Heat & Power) is the joint and simultaneous production of electricity and
thermal power (warm water, overheated water or steam, diathermic oil) generated from a single source
of primary energy. A recent evolution of the cogeneration concept is “Trigeneration”, that is obtained
connecting a cogeneration unit to an absorption chiller, a special refrigeration process machine.
Such system takes advantage of the thermal energy in output from the cogeneration unit, so to
produce cool water, available for air conditioning/climatization purposes or for industrial/manufacturing processes.
All these systems are today technically mature and economically convenient for diffused applications.

In a cogeneration system, with the input of 100 units in primary energy (fuel), are obtained in output
65 units of thermal energy and 30 units in electricity, thus lowering the process losses to only 5 units.
To attain the same quantities in thermal and electrical energies through a traditional system (boiler and
national electricity grid), the overall primary energy needed amounts to 166 units in fuel.
Then a cogeneration system allows energy savings worth about 40%.

ENERGETIC AND ECONOMIC ANALYSIS
Losses = 10
The cogeneration unit is basically made through the coupling of an endothermal Otto cycle engine to
an electric alternator. Such configuration will enable the cogeneration unit to convert the mechanical
energy from the engine into electric power. At the same time, by means of dedicated heat exchangers,
the heat produced by the engine itself and the exhaust system, instead of being wasted through dissipation, is fully recovered, and sent in parallel with the existing hot water system for the
user. This combined solution possible to produce energy with efficiencies that can reach even
exceed 90%. It follows a primary energy savings of 30-40%, contributing a reduction of
CO2 released into the atmosphere.

Sizing criteria
In the aim of finding the best fit solution for the user it is necessary to perform a full analysis of the
monthly electric and thermal consumptions in energy, on a yearly basis. Afterwards data are to be collected about the not labour days, month by month, the working table time and the connected shifts.
Another important factor in submitting a cogeneration proposal is a full comprehension of the production cycle, so to best optimize the use of the produced energies in cogeneration and trigeneration.
Such information will enable to find out, with a good confidence level, how many hours a day the user
is active, and plot out the thermal and electric consumptions through a whole year.
By means of the consumptions profiles, it results possible to find out the best fitting size for the cogeneration unit to be installed. Then a simulation is made about the quantities in power and thermal
energies that the CHP unit can produce through a year, month by month, working for the expected
daily hours, so calculating the net economical benefits, taking into account all the operating costs.

Cogeneration unit proposal
In the aim of the best economic value for a cogeneration solution it is necessary to calculate the right operating hours mix,
in a way such as that the CHP unit doesn’t overproduce energies, both thermal and electrical,that will not be used. Our units
can modulate the output power accordingly to the actual user’s needs, stiil keeping their efficiency at a high rate. Still
attaining high performances when operating in a modulation mode, generally the minimum power output is kept not under
the 50% of the nominal power. Trespassing such a value means to invalidate all advantages from the CHP technology.
Thanks to the feasibility study and the comsumption profiles, it results possible to find out the right size CHP solution.

From the diagrams, it is apparent how the production of electric
power through the cogeneration unit reduces the feeding from
the grid. This occurs most in the winter season, when the thermal
energy demand enables a high number in operation hours. In the
summer season, in order to avoid a possible dissipation for the
extra produced heat, the working hours for the CHP unit will result lower, then covering a little less in the electric energy needs.
Thanks to the trigeneration technology, in the summer season it
results possible to use the produced hot water to obtain refrigerated water, to be usefully sent to the climatization system.

REC2 is a range of high efficiency microcogenerators, fuelled with natural gas and LPG.
The units are suitable for the production of thermal and electric power. Their configuration
heavy duty /low speed (1500 rpm) guarantees a particularly long life operation for the
equipment. The cogenerators are constituted from an endothermic motor coupled to an
alternator and fixed to the metallic base through antivibrating joints.
Taking advantage of the produced mechanical energy of the motor, the alternator produces
electric power fit for the grid. From the cooling system of the engine and from the exhaust
circuit, thermal energy is duly recovered for civil and industrial uses. The constructive characteristics of the exchangers and the engines allow the operation of the units within a range of
temperatures for incoming water from 32°C to 84°C. A programmable electronic system surveys the operation, the regulation, the emergency devices and the remote control connection.
1. THERMAL LOAD FOLLOWING LOGIC
Controlling the incoming water temperature from the user,’s circuit, the equipment will modulate
the generated power in order to maintain the outcoming water temperature at a prefixed value.
2. ELECTRICAL LOAD FOLLOWING LOGIC
Measuring the electrical absorption of the user from the grid, the unit will modulate the produced
power, matching the user ‘s electrical load. For this logic of operation it is necessary to install an
amperometric transformer accessory TA, in order to control the amount of electric power to be
produced, and the accessory “dissipator of thermal energy” in order to dissipate, in case of need, the
extra thermal energy (hot water) produced from the cogenerator and not used by the user’s system.
3. FIXED POINT LOGIC
Setting up a target value of temperature to be attained , the cogenerator will work at full load
and, when the target value results attained, it stops. When the temperature lowers at a level
under a preset second target value, the control system of the cogenerator automatically restarts
the unit at full load operation. If the fixed point is related to the electrical load following logic it
is necessary to include in the order the “dissipator of thermal energy”. If the fixed point is related
to the thermal load following logic no other accessories are needed.

LPG COGENERATION
LPG
Where the natural gas distribution net isn’t available, one is anyway allowed to take advantage from the cogeneration technology. As a matter of fact, within certain sizes, a wide
range of endothermal engines fuelled through LPG (Liquefied petroleum Gas) is available. Such engines are fully complying with international rules and result to be very reliable and highly tested in field operation.
LPG is a mixture of Hydrocarbons low in their molecular weight. The mixture is mainly composed from propane and buthane, with an occasional presence of ethane or other not saturated
hydrocarbons, such as, e.g. ethylene and buthylen. LPG is worth its name since its components,
in standard conditions (Ambience temperature and atmospheric pressure) exist at the gaseous
state.: they are liquefied through compression at relatively low pressure rates, namely between
2 and 8 bar, so to reduce their volume and maintain their transportation costs at a cheap level.
WHY TO USE LPG
The main advantage consists in attaining the mixture density to be 250 times higher than
the gaseous state, then reducing its volume at the same mass and so allowing the storage
into vessels limited in size and pressure requirements.
Thanks to its reduced content in sulphur and to a complete combustion, with
very low residuals, the use of LPG gives a good contribution in lowering the environmental impact, promoting a better quality of the air and a reduction of the
green-house emissions.
The LPG density, that is its weight per litre, is different according to its composition and
the environment conditions, also considering the weather seasons. Generally an average
density equal to 0.51 kg/litre is assumed, together with a LHV (Lower Heating Value) value
of 5,500 kcal/litre, in standard conditions, that is 15 °C temperature at the sea level. In
the gseous state, lPG ha sa density higher than the air itself, and for such reason it is not
allowed to diffuse into the atmosphere. For safety reasons a special rule is to be applied
(in Italy from the Ministry of Interiors, Fire Brigade Recommendations).

kWe
The range from 100 kWe to 500 kWe has been developed for solutions standardized in
container, both in cogeneration and tri-generation versions.
All the Enerblu Co-generation range is conceived so that all the thermal exchangers and
dry cooler units are entirely planned and manufactured inside Enerblu itself, thus obtaining
constructive and original solutions that make our groups extremely efficient and compact.
Close to such characteristics, that make our cogenerators very special, a lot of attention has
been placed into the control system. Remote operation of the entire cogeneration plant is
enabled from a far location. Thanks to the particular control system, also the remote regulation of the operation parameters of the cogenerator engine is enabled.

Enerblu boasts a line range of natural gas units in modular solutions or related to a
single motor.
The range of GREAT CO-GENERATION from the 600 kWe until to the 4 MWe has been developed for solutions standardized in container, both in cogeneration and tri-generation versions.
All the Enerblu Co-generation range is conceived so that all the thermal exchangers and
dry cooler units are entirely planned and manufactured inside Enerblu itself, thus obtaining constructive and original solutions that make our groups extremely efficient and
compact. Close to such characteristics, that make our cogenerators very special, a lot of
attention has been placed into the control system. Remote operation of the entire cogeneration plant is enabled from a far location. Thanks to the particular control system, also
the remote regulation of the operation parameters of the cogenerator engine is enabled.

Enerblu has available a complete range of biogas cogeneration units apt to satisfy all
the requests coming from the world of the zootechny, from sewage depuration plants
and from waste landfills plants.
The range covers the electrical power production from 60 kWe until 999 kWe, with the
possibility, on specific demand, to arrive up to 2 MWe.
Enerblu is in a position to tailor suit the supply on specific demand for the customer
and to issue a project that in every case is aimed at the maximum energetic efficiency
of the system.
All the biogas cogenerators are supplied with sound-proof cabin or container. Upon
request they can be supplied also in the so-called “naked” version, ready for installation
on existing technical premises.
EXAMPLE
Biogas plant 100 kWe
potential size for cattle briding farm
350 adult cattle
> 6.000 tons per year of manure
production of 200,000 m3 of biogas per year
330,000 kWh/year of electricity
Energy saving for the country = 62 tep/year (tons of oil equivalent)
Reduction of emissions in to the atmosphere = 180 tons/year of CO2 (carbon dioxide)

(*) Values lower emissions are achieved with the catalyst bivalent for CO and with SCR systems for NOx.
(**) On request of the customer is possible to increase the thermal power recovered approximately 17.1 kW.
The data refer to the percentage of methane by 60 % up to 360 kWe and 55 % from 400 to 999 kWe.
SYNGAS
THE PLUS:
> Full range 50 – 200 kWe
> Very low levels in the emissions
> Environment sustainability
> Development of the so called
“short distance” energy supply
kWe
An electric power generation plant, fed through wood biomass, in a CHP version and
power ranging from 50 to 200 kWe, by means of the gasification technology.
The piro-gasification technology, from wood biomass, consists in a thermochemical conversion process that transforms the energy content of the wood/vegetal biomass itself
into a specific gas, named syngas. The produced syngas, in turn, results to be an energetic
vector capable to produce thermal and electrical energy, fuelling endothermal engine
driven CHP units, operating downstream the gasification plant.
BIOMASS
The woody biomass fit for feeding a pirogasification plant is complying with the rule
EN 14961-4 as A2 P63 M35 and it can include chips up to the range of a generic type.

PLANT
Plus typical for RES (Renewable Energy Sources):
> Environment sustainability
> Ascertainty in the supply
> Lower dependence from foreign countries
> Energetic sources diversification
> Development of the so called
“short distance” energy concept
Plus typical for biomass:
> Zero emissions in the balance
of the Carbon dioxide
> High availability in the territory
> Allowance for an alternative use
of wastes, otherwise difficult and
costly for their treatment
ADVANTAGES FROM BIOMASS COGENERATION
1. Energy efficiency: the pirogasification of woody biomass produces more electric
energy – respect to an equal amount of used biomass - compared to that one produced by traditional systems, such as combustion boilers or biogas systems.
2. Environmental: the pirogasification process ensures incredibly low emissions levels,
since the whole process occurs intotal absence of oxygen (then without combustion); besides the biomass that usually is sent to landfills or is simply burnt, can be
reconverted and then used like a “green fuel”: an existing cost for the community is
then transformed into an important resource.
3. Socio-economic: the pirogasification process allows the start-up of profitable lines in
keeping and cleaning the green territories (forests and woods), for selection and quality improvement of the environment, and valorization of the Mountain Communities.
