  • What is the difference between gas boilers and coal-fired

    Jun 28, 2019 · First, the way of burning. Most of the coal-fired boilers use the layer-fired combustion method. 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 Learn More
