coal boiler furnace modified gas boiler

What is the difference between gas boilers and coal-fired

The coal passes through the coal-feeding machine to transport the chain grate plane, and the combustion process is completed in the furnace. Most of the gas boilers use chamber combustion, and the natural gas is mixed with the air in the burner in a predetermined ratio, and then injected into the furnace through the nozzle to complete the combustion in the furnace state.

Coal to Gas Conversion — Reaction Engineering International

Gas CoFiring marries natural gas and coal at each burner, injecting through a modified igniter. It also adds a portion of the total heat input as gas in the upper furnace (this is known as Fuel Lean Gas Reburn). The model was first run under "current" operating conditions (coal-firing).
