As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
Although normally used in hydronic boiler applications, the Coal Gun can be adapted for use with forced hot air systems through the use of a water to air heat exchanger. Pulverized coal-fired boiler. Coal is ground to the size of a fine grain, mixed with air and burned in the flue gas flow. Biomass and other materials can also be added to the mixture.
