fluidized bed

coalfiredsteamboilerBHF

The boiler is a combination of water tube and fire tube design, natural

circulation, balanced draft unit, suitable for indoor installation and is

provided with atmospheric fluidized bed furnace to burn the coal.

The boiler assembly, consisting of fluid bed combustor, in-bed tube

bundle, water cooled furnace, and the fire tube boiler is supported on

concrete platform while the other equipment like dust collector, air

heater, etc. is supported on steel structures.

• Fluidized bed combustion is the latest coal firing technology, gives

very high combustion efficiency (95-99%). The effective fuel-air

contact means lesser excess air needs which gives high boiler

efficiency. By adding an economizer to pre heat the feed water, the

total system efficiency can be made higher than any other boiler

make.

• Basuki Steam Boiler offer a complete range of clean coal technology

covering fuel handling, fluidized bed combustion system, ash

removal and air pollution control system.

• Basuki Coal-fired boiler can give you lowest cost of steam as they

burn cheap coal to generate steam.

You can reduce the operating cost of your plant substantially by

using the revolutionary fluidized bed boiler.

Cheaper coal fines can be used to reduce the cost of operation.

When coal burns in the fluid bed, some of the ash and the stones, etc.

accumulate in the fluid bed. These large particles have to be drained

from the bed to maintain stable fluidization.

A small amount of bed material will be drained periodically from

bottom of the bed to remove the stones and small clinkers if any.

A manual bed material draining system including levers is provided at

the bottom of the air plenum.

main advantages of basukifluidized bed boiler

Low Operation CostCheaper coal fines used as fuel, size of coal required is 100 % below15 mm.

Fuel Flexibility100 % capacity of the boiler can be obtained with nearly all types ofcoals. No capacity reduction for lower heating value.

Low Maintenance CostVery reliable as the only moving part is the fans which are outside thehot zone.

6

Higher boiler total efficiency than boiler using chain grate

The capacity of boiler is specified at the working pressure with feed

water at 30 C. Not on F&A 100 C basis

Large external furnace with large volume and hence higher

combustion efficiency (95-99%)

Large amount of refractory lining which gives higher furnace

temperature for better combustion

The combustor can be started immediately after up to 4 hours shut

down without any pre heating as the sand bed retains heat

Very quick turndown is possible and thus very quick load response

Materials like sludge and waste can be incinerated along with the coal

Produces very low NOx and SOx emissions
