EPRI contracted an economic study on the use of Texas lignite in atmospheric fluidized bed combustion (42), and projected that the costs of AFBC would be less than those for pulverized combustion plus flue gas desulfurization. However, while AFBC appears feasible for small-scale units (less than 50 MW ), there is some doubt that large scale utility AFBC systems can operate successfully. Part of this problem stems from the inadequacy of "bubbling bed" design normally used in AFBC newer designs, such as the circulating bed, offer more promise for commercial application and are being tested presently (32). 

Limestone incorporation to coal feed during coal atmospheric fluidized bed combustion (AFBC) to control legislated emissions promotes the polyaromatic hydrocarbon (PAH) emissions. This is a fact that has been corroborated working in a laboratory pilot plant at the same eonditions used at the coal FBC power stations. PAH emissions increase one order of magnitude but, is it due to a Ca catalytic effect or is it due to limestone is a porous material ... 

Fluidized bed combustion of coal is used to reduce the emission of sulfur dioxide and NO into the enviromnent. In this technology the pulverized fuel is burnt in a fluidized bed combustor after being blended with limestone or dolomite, which act as soibents for SO2. The burning temperature is significantly lower than is common in the production of fly ashes in suspension-fired furnace chambers, at around 850°C. The process may take place at atmospheric pressure (atmospheric fluidized bed combustion, AFBC) or elevated pressure (pressurized fluidized bed combustion, PFBC).

It should be noted that FGD systems ate not the only method of controlling flue gas SO2 emissions. Other potoitial methods are fuel cleaning, switching, and blending unit retirement purchase of SO2 emission allowances (in the U.S.) and the use of other technologies such as atmospheric fluidized bed combustion, pressurized fluidized bed combustion, gasifi-catimi with fuel gas dean-up, etc. Only FGD systems ate discussed in this chapter.
