3 - Pass Drying Drum Station Type Dry Mix Mortar Manufacturing Plant 300000 Ton Output Per Year

3-pass drying drum station type dry mix mortar plant with 300000 ton output per year

Fluidized bed furnace

In furnace, crushed dust coal will be blown to certain height and burned like boiling, it has the following advantages:

1 better adaptability for many kinds of coal: soft coal, hard coal, and gangue, and also available for any kind of inferior coal.

2. Sufficient burning to improve combustion efficiency. Average temperature of boiling material layer keeps between 850 and 1050, due to thick layer of material like a big heat reservoir, in which fuel only contain around 5%, newly added coal particles mix quickly after coming into material layer and burn quickly, therefore which can be replaced by gangue.

3 Due to low burning temperature of , generated NOX quantity is not high, if adding right amount of limestone or dolomite into incoming material, sulfur content will be removed to reduced SO2 content in discharged gas.
