Methods for reducing the temperature and pressure of ash and slag in low-order pulverized coal gasification technology
Thread Content
I’m seeking advice from experts: In low-order pulverized coal gasification technologies, dry slag discharge is used to reduce the temperature and pressure of the slag. The slag coming out of the gasification furnace is at 900 degrees Celsius, and it needs to be reduced to below 300 degrees Celsius. Conventional slag coolers can only operate at atmospheric pressure, but since this is a pressurized gasification process, it is necessary to cool the slag under pressure. I would like to know what type of slag cooler structure can meet these requirements, as well as whether there are any manufacturers that supply such equipment; we are planning to purchase this kind of device
