1.7 Lignite Combustion - US EPA

2020-9-25 · Pulverized coal units have been designed for both wet and dry bottoms, but the current practice is to design only dry bottom furnaces. Another type of boiler firing lignite is the cyclone burner, which is a slag-lined high-temperature vortex burner. The coal is fed from the storage area to a crusher that reduces the lignite into particles of
