Three Ways to Optimize Solid Fuel Combustion - Hurst Boiler

Take stack readings to see the correlation between the carbon monoxide and oxygen levels to determine the best oxygen setting for a respective boiler system. Understanding how a solid fuel boiler works boils down to understanding the fuel and the combustion process as well as the equipment that controls how the fuel is burned.

What is a Boiler?

Chain Grate or Traveling Grate Stoker Boiler Coal is fed on one end of a moving steel chain grate Coal burns and ash drops off at end Coal grate controls rate of coal feed into furnace by controlling the thickness of the fuel bed. Coal must be uniform in size as large lumps will not burn out completely Bed thickness decreases

instead of water & carbon dioxide. Oxygen has greater tendency to combine with hydrogen than with carbon. So fuel normally burns to completion forming H 2 0. As a result, some carbon ends up as carbon monoxide or just plain carbon particles, soot, in the products. Incomplete combustion means that fuel is inefficiently and can even be hazardous
