Grate Boilers for 2x10MW Biomass Power Plant
2*10mw biomass power plant requires steam boilers to provide driving force. No matter chain grate type boilers or circulating fluidized bed boilers are available for the 10MW biomass power plant.
How is electricity created with biomass?
Direct combustion is the simplest and most common method of capturing the energy contained within biomass. In biomass power plants, wood waste or other waste is burned to produce steam that runs a turbine to provides electricity and heat to industries and homes. Fortunately, new technologies — including pollution controls and combustion engineering — have advanced to the point that any emissions from burning biomass are generally less than those produced when using fossil fuels (coal, natural gas, oil). Direct combustion technology is very similar to that used for coal, but biomass does not have the elements like sulfur and mercury that are found in coal, and its emissions are therefore safer.
Corner tube biomass boiler for 10MW power plant
1. The boiler adopts corner tube pattern, self-supporting structure, problems relating to the expansion and the supporting of corner tube boiler is tackled smartly. Supporting structure is stable and compact.
2. The furnace and the down flow gas duct adopt total welding membrane water cooling wall structure, which has the features of good sealing, less heat losses, and clean.
3. Air pre-heater and economizer adopt case structure that can ensure them be transported in package, to shorten installation period and strengthen the seal ability of the fuel gas duct.
4. There is flag pattern heating surface before the high temperature super heater, so the high temperature ability of the super heater can be ensured, meanwhile, the super heater can be operated in the serious fuel gas environment stably.
5. The cross girder grate is adopted, so it has the features of less operation resistance, better grate cooling effects, lower breakdown rate, less fuel leak. And the grates are made by the first class professional manufacture.
