fluidized bed combustors for biomass boilers

what is chain grate fluidized bed combustors for biomass boilers

Grate firing has been the most commonly used firing method for combusting solid fuels in small and medium-sized furnaces since the beginning of the industrialization. Coal, waste and biomass fuels are usually burned in grate boiler. In the chain boiler, the coal is moved backward from the front of the grate, and the air from the bottom up to the furnace, and as the furnace is constantly moving backwards, the fire, combustion, burning and other stages occur in sequence. Traveling or chain grate stokers feed coal out onto a rotating metal belt that supports the fire. Solid fuel is fed from a hopper. Grate speed is automatically controlled to maintain desired steam pressure. Burning progresses as the belt moves from front to back of furnace. Combustion is essentially complete at the back end of belt, and ash is dumped off into an ash pit there.

In early November, the annual "Technology Innovation Award" announced by the Chinese Ministry of Science and Technology Venture Association. Fast Boiler Co., Ltd. With strong R & D strength and strong R & D hardware infrastructure was awarded The "Technology Innovation Award (business)," the honorary title.

2.Biomass fluidized bed combustors for biomass boilerss offer fantastic efficiency

Modern biomass combustion systems are highly sophisticated, offering combustion efficiency and emission levels comparable with the best fossil fuel boilers. Using modern technology they can currently operate at 90% efficiency which is vastly higher than conventional boilers and electric heating systems. Like heat pumps and other renewable heating sources their efficiency also depends on how energy efficient your property is. The type of system you use, its flue and the air flow around the boiler are all aspects to consider as well. Most properties will benefit from additional energy efficiency work before the biomass boiler system is installed.

Now we have many types steam fluidized bed combustors for biomass boilers for chili sauce factory, there are gas fired steam boiler, oil fired steam boiler, coal fired steam boiler, biomass fired steam boiler, solid fuel steam boiler, straw steam boiler. The chili sauce plant can choose the suitable steam boiler according to the fuel cost in the local.

Fluidized bed combustion - Wikipedia

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
