The combustion in a fluidized bed boiler is characterized by thorough mixing and intensive movement of fuel in a dense cloud of heated solid particles under controlled temperature conditions. This excellent mixing leads to improved heat and material transfer during combustion allowing various fuels to be fired simultaneously in the same boiler.

The firing method most commonly employed for wood-fired boilers with a steam generation rate larger than 100,000 lb/hr is the spreader stoker. In this boiler type, wood enters the furnace through a Simultaneously, larger pieces of fuel are spread in a thin, even bed on a stationary or moving grate. The burning is accomplished in three

Oct 05, 2014 · A wood-fired heating appliance may be vented into the same chimney flue as an oil-fired heating appliance provided that they are on the same floor - in some jurisdictions. Combination wood-oil fired heating boilers join wood and oil burners in the same physical unit, making this exception necessary if the boiler is to be used at all.

For a boiler fired simultaneously with bagasse and natural gas, a yield of 68.3% and an index of 1.87 kg of steam/ kg of equivalent bagasse were recorded. To validatethis methodology, these values were contrasted with the efficiency values obtained in accordance with the American
Read MoreAug 30, 2002 · All boilers connect to a common set of headers that in turn connect to the main system piping using a closely spaced set of tees (e.g. primary/secondary piping). This prevents the system pump from interfering with flow through the boilers. Again, each boiler's circulator only operates when the boiler is fired.
