FBC is a process of burning coal in which the coal is inserted in a bed of particles that are suspended in the air and that react with the coal to heat the furnace more cleanly. In FBC, coal is burned at a slightly lower temperature, which helps prevent some nitrogen oxide gases from forming.
A process in which combustible materials are introduced into a greater volume of hot inert particles, contained in a chamber and maintained in a state of turbulence by a stream of gas (usually air) from below, during their thermal conversion. The process can be pressurized.
A method of burning coal to achieve lower emissions by combining coal with limestone or other similar material held in suspension by air moving upward through the boiler.
