Aug 09, 2018 · Firebox and Combustion Chamber of Furnace. Firebox of boiler furnace is the place just above the grate and combustion chamber is the extension of this where combustion of volatile hydrocarbons take place. The heat is produced due to combustion is absorbed by the steam boiler surface at the top of the combustion chamber. Different fire bricks
Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.
The wood pellet boiler uses long-lasting, low energy, hot surface igniter for ignition. Other unique features that set the boiler apart from other wood pellet boilers are a combustion grate that slides to clean while at the same time integrating a chimney cut-off function to retain heat in the boiler
Almost any home can be retrofitted with a wood pellet boiler, either as a stand-alone heat source, or as a primary heat source in conjunction with a secondary boiler which serves as back up, or in some cases, as a supplementary heat source. Past, present, future: Until recently, pellet boilers have been virtually non-existent in the US.
Grate Furnace: The combustion of the biomass occurs on a grate with a primary air flow underneath the bed and the combustible gases produced are burnt with a secondary air flow. These systems place the fuel on a grate and the ash produced is disposed off automatically. It has a few types such as fixed grate, moving grate, travelling grate and
