clean coal technology basuki heater
Coal is widely available and cheap fuel for industries. We offer highly
efficient Thermal Oil Heater using bituminous coal as fuel. Now you can
get the advantage of the low cost coal to run your process.
Basuki Thermal Oil Heater offer a complete range of clean coal
technology covering fuel handling, fluid bed combustor, ash removal
and air pollution control system. Standard models with capacity from
400,000 kcal/hr to 6,000,000 kcal/hr, using variety of solid fuels. Other
capacity are available on request.

• Fluidized bed combustion is undoubtedly one of the most attractive
means of burning coal due to its various advantages. Basuki coal fired
thermal oil heater consist of a coil type heat exchanger located above
a fluid bed furnace. Coal is burnt in a fluidized bed combustor. This
produces minimum pollution and can ensure complete combustion of
the fuel. fluidized bed combustor can burn a variety of solid fuels such
as wood waste, rice husk, palm shell and coal in same unit. Effective
mixing of fuel and air in the reactor makes it possible to obtain
complete combustion with less excess air.
• Fluid bed combustion and effective secondary air distribution results
in complete combustion of coal and produces less carbon monoxide
(CO) and almost white smoke. Due to low temperature operation of
the fluid bed combustor ( about 800 – 900 C) low amount of NOx is
produced by avoiding oxidation of nitrogen compounds contained in
the coal. For high sulfur fuels, it is possible to trap the sulfur in the bed
and avoid costly de-sulfurisation equipment. Higher thermal efficiency
can be obtained using bituminous coal due to low excess air and low
stack temperature.

Low Operation Cost
Cheaper coal fines used as fuel, size of coal required is
100 % below 15 mm.
Fuel Flexibility
100 % capacity of the boiler can be obtained with
nearly all types of coals. No capacity reduction for lower
heating value.
Low Maintenance Cost
Very reliable as the only moving part is the fans which
are outside the hot zone.

other advantages of
thermal oil system
Low Operating Pressure
Thermal Oil systems operate at a maximum system pressure of 5 barg
and can supply hot fluid at temperature up to 300 C. A hot water or
steam system for this temperature will operate at higher than 60 bar
pressure.
Higher System Efficiency
Thermal Oil heating systems give higher thermal efficiency than steam
systems as there is no condensate loss.
No Scale Formation or Corrosion
The mineral oils used for the heating plant are non corrosive and are
stable at the operating temperature. The heating plant can operate for
long time (8 – 10 years) without needing change of fluid or system
cleaning for scale, corrosion, etc.

other advantages of
thermal oil system
Low Maintenance Cost
Thermal oil plants require lesser maintenance due to the closed loop
operation and simple construction.
Fully Automatic
The entire heating plant from fuel storage, feeding, combustion and the
oil circuit operates automatically to give continuous supply of hot heat
transfer fluid to the process. There are adequate safeties to ensure a
safe and reliable operation.
No Need of Softener
Thermal oil systems do not need equipment like softeners as required
for water or steam system.
