FBC boiler Flashcards
What is FBC boiler capacity ?
0.5 TPH - 75 TPH
What is the meaning of FBC?
Fludized Bed Combustion
what are the advantages of of FBC boilers?
a. Fuel Flexibility
b. Emission performance
c. re-use of non-hazardous by-products ( e.g. gypsum) and
d. possibility of the technology to be implemented in an existing plant
What is packed bed?
A fluidized bed consists of a stream of gas flowing upward through a bed of solid particles such as ash or sand. At low gas flow rates, the gas permeates through the bed without disturbing the particles and is called a packed bed.
What is Fluidized Bed Combustion?
A fluidized bed combustion boiler is one where combustion takes place over a fluidized bed.
If the sand in a fluidized state is heated to the ignition temperature of the coal and the coal is injected continuously into the bed, the coal will burn rapidly and the bed attains a uniform temperature due to effective mixing.
This, in essence, is fluidized bed combustion
