Can cinder with a carbon content of 25% be used in a boiling furnace?
Thread Content
Our company has pulverized coal slag with a carbon content of 25%. Can it be used as raw material for boiling furnaces? The slag particles are less than 1 mm.
Oops, why does the slag have such a high carbon content?
It should be possible. Nowadays, many fertilizer plants sort and process the slag from fixed-bed gas generation, and mix it with bituminous coal for use in circulating fluidized bed boilers. The proportion is about 25%-30%. However, the problem caused by this is that the life of the boiler buried tube is shortened.
We should first improve the current furnace. The carbon content in the slag is too high. I agree with the 3rd floor. Not only is the life of the boiler buried tube shortened, but the furnace is not easy to control and is prone to problems.
The cinder you mentioned is difficult to burn. Although the carbon content is relatively high, the key is that the particle size is too fine. When it enters the boiling furnace, it will be carried away by the wind, which will increase the load on the ash removal system.
I want to use the slag from the waste pot of Ende Furnace to burn the boiling furnace to produce hot air-baked lignite.
