11
Design and planning:

Definition of plant parameters: pressures,
temperatures, capacities, (warmwater,
hotwater, steam, thermooil)
Determine the annual heat consumption
(min - max. capacities, annual operating
hours table )
12
annual heat consumption of district heating
Design and planning: AVAILABLE FUEL

Accurate definition of the used fuel (min/max. watercontents, size, ash contents,
chemical analysis ) to fix the feeding and
combustion system
Determination of the ingredients of fuel
as nitrogen, clorine, sulfur, o.s.o. to fix
the flue gas cleaning system according to
the valid emission levels
14

Design and planning:
Nitrogen in the fuel:
valid for level of NOx (NO2) : SNCR-plants,
SCR- plants or other NOx reducing methods
Chlorine:
valid for HCl-value in flue gas and high
temperature corrosion; Fix the heat transfer and
max. temperatures in the boiler
Sulfur:
valid for SO2-value in flue gas, raises up the
dew-point of the flue gas (corrosion)
15
Process engineering

Definition of the proceedings according to the
costs and economics
Definition of the boiler parameters and fuel
feeding / storage / and flue gas handling and
cleaning.
Choice of the flue gas cleaning system:
multicyclone
electrostatic filter
bagfilter

Energy from Biomass
Wood combustion doesn’t
contribute to greenhouse effect,
because the disengaging carbon
dioxide originated from
combustion, will be bound by
photosynthesis in growing up
trees / plants.
Therefore the CO2 – balance
is equalised.

Biomass based heating plants
use local, natural energy
sources, which are renewable by
photosynthesis.
