Is there coal of different types that is crushed before being fed into the furnace?
Thread Content
By blending coal of different particle sizes based on the type of coal and its degree of crushing, it is possible to **reduce the caking tendency of the coal fed into the furnace, thereby avoiding an impact on coke quality and cutting costs.
This method is particularly more effective in top-fired coal furnaces.
You mean the process of powdering first and then mixing, right? In other words, there is one crusher for each type of coal; these are used to crush the coal separately before it is mixed in different proportions. This will increase investment in infrastructure.
There’s no need for such complexity; just two types of crushers are sufficient, and the coal can be mixed after crushing. If the cost of coal used in the furnace can be reduced by 100 yuan per ton, then the cost of adding another crusher won’t be a problem!
100 yuan is quite a significant amount; 1.2 million tons per year equals over 100 million, so it’s worth adding more crushers.
Mm-hmm, the fineness of coal powder has an impact on coal blending
I hope everyone will actively participate in the discussion – which company is willing to be the first to try this?!!!!
I’ve also seen two crushers, which are used for selecting the type of crushing to be performed. For coal that is difficult to crush, it is first crushed once, and then fed together with other easily crushable coal into the second crusher. The second grinding process is also a process of mixing coal types.
That’s completely different! ! ! ! ! ! ! ! ! !
