firefiting system in coal mill

Re: firefiting system in coal mill. If the coal mill temp goes high, it can ignite the coal and result in explosion inside the mill and components. Thats why the CO2 is injected into the mill to create a inert condition, means to reduce the Oxygen content inside the mill to avoid any firing/explosion. If the CO2 system is not working, we can ...

Coal bunker / coal mill | S. r. Thermonix Technologies

Coal bunker / coal mill. Pulverized coal is typically used to fire the boiler of power plants. Due to safety reasons, monitoring of CO in coal bunkers and coal mills is an essential issue. CO is an odourless and very toxic gas and imposes a serious explosion thread at levels above 8 vol.% in air.

Coal Mill

The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.
