How to Prevent Slagging in a Boiler Furnace

How to Prevent Slagging in a Boiler Furnace

Slagging and deposition in coal fired boilers is a complex phenomenon. The reasons can be due to coal characteristics, operating conditions, the design of the boiler furnace, or can be a combination of any of the three with others or all.When heavy deposition or slagging starts in the boiler, the boiler operating group can contain the problem, to a large extent, by taking corrective action.

Boiler Performance and Mill Outlet Temperature

Boiler Performance and Mill Outlet Temperature

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is .

Emergency inerting systems for coal-grinding applications

Oct 21, 2011 · In the case of coal-grinding or storage (as one might find in a cement plant) it is not possible to remove the fuel (coal) or ignition source (grinding energy, heat, static charges) and so one has to concentrate on removing the third necessary component - O 2. This fact has given rise to inerting systems that rely on the use of inert gases.
