Coal seams can be set on fire by spontaneous combustion or contact with a mine fire or surface fire. Lightning strikes are an important source of ignition. The coal continues to burn slowly back into the seam until oxygen (air) can no longer reach the flame front. A grass fire in a coal area can set dozens of coal seams on fire.

Jun 26, 2015· Grate bars, tuyeres and retorts are not subjected to high temp as they remain contact with fresh coal Overload capacity of the boiler is high as large amount of coal is carried on the grate Smokeless operation is possible even at very light load With use of clinker grinder, more heat can be liberated out of the fuel
Mar 15, 2019· Hard coal has a much higher BTU content, but ignites slower and takes longer to give up its heat. The larger grate area allows for a thinner fire, which helps ignite the hard stuff faster - which is important when you have such variable heat/steam demands on a locomotive, and more of it, which helps compensate for deficiencies in firing.

Clinkers form in both coal and oil fired engines. Generally in coal firing they are in the coal bed and can form on the tube sheet in a configuration somewhat like a honeycomb. In Oil fired engines clinkers form anywhere the oil/fire stream may stike the brick work. In oil hard firing can spray oil against the flashwall forming a large carbon mass.
Jun 16, 2011· Converting from coal to oil firing. To do it right, you should completely replace the boilers.
