The influence of coal quality parameters of briquetted coal on the gasification process
Thread Content
The impact of coal quality parameters of briquettes on the gasification process, including the ash content, volatile matter, ash fusion point, reactivity, thermal stability, and water resistance of briquettes – fellow enthusiasts, share your insights!
The level of ash content in briquettes affects the reactivity and economic efficiency of briquette gasification； Volatile matter has an impact on the strength of briquettes after they are formed. When used in fixed-bed gasification, a high ash melting point facilitates slag discharge; therefore, it is advantageous to have a high ash melting point ； The reactivity, thermal stability, and water resistance of the raw coal all have a positive effect on briquettes!
From a practical standpoint, the ash content of briquettes, as well as their moisture content and mechanical strength after production, have a significant impact on the gasification process. High ash content prevents an increase in the gasification load, leading to reduced economic efficiency and lower gasification efficiency. Excessive moisture causes the briquettes to become fragile when exposed to heat in the furnace; especially when their mechanical strength is low, they tend to turn into powder, resulting in an increase in the amount of waste produced.
