Moss fluidized bed combustion systems can be used on many different boiler or dryer systems. Because of stricter emission regulations in the United States as well as other nations and the need to combust more difficult fuels for energy production, we believe this is the gasifier combustion system of the future. This system can burn dry or wet solid fuels and/or gases and liquids. Fuels from wood, sludge’s, coals, tires, rice hulls, corn products, chicken or turkey liter, cotton seed hulls, coffee grounds, etc., can be burned in this very flexible system. Moss fluidized bed gasifier combustion systems can even burn all types of coal with limited emission cleanup equipment required to meet sulphur dioxide emissions.

The bed is comprised of an inert material (typically sand or crushed limestone – depending on the fuels to be burned) that is preheated to approximately 1000° F. (538° C.) prior to the fuel being injected. Once fuel is injected into the bed, temperatures within the bed are generally controlled to operate between 1250 - 1450° F. (677 - 788° C.). This system provides the capabilities of recovering energy from unusual and difficult fuels, while emitting low exit stack gas emissions. Fuels are either augured below the surface of the fluidized bed or are pneumatically injected above the fluidized bed, where the smaller fuel particles are quickly volatized and the larger pieces falling into the fluid bed media where low emission heat is released into the freeboard area. Once in the freeboard area, overfire air nozzles inject air to combust any unburned gases and are usually controlled to temperatures in the 1800° F. range before being released to a heat exchanger or to the plants process heat requirements.
