small fixed grate coal fired boiler
A small fixed grate coal fired boiler thermal efficiency improve conventional coal-fired boiler mostly thermal efficiency of about 70%, a large portion of the energy due to heat loss or otherwise be wasted, the use of gas boiler after the "coal to gas", the thermal efficiency will be 20% -40% improved. Second, lower investment costs than the price of coal gas prices high, but in addition to fuel costs, only the investment pipeline can. The investment in coal-fired boilers in addition to fuel costs, as well as transportation costs, labor costs, storage costs, the overall price is not cheap. From the cost point of view, natural gas overall advantage. Third, improve environmental benefits due to the combustion of natural gas itself is adequate, and clean burning, non-polluting emissions is a more environmentally friendly energy sources. After coal combustion emissions from sulfur, more ash, environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise.
The first half of the small fixed grate coal fired boiler end of the oven wood oven, after completion of the coal oven according to the requirements, at this time, should increase the degree of opening of the blower, draft fan slightly open, close the door, ash door, to further improve the smoke temperature, to bake the purpose of the dry furnace wall.
Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam small fixed grate coal fired boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.
Fluidized bed small fixed grate coal fired boilers are the most recent type of boiler developed for solid fuel combustion. And 35 ton coal fired CFB steam boiler is hot sales in industrial market. As a top steam boiler manufacturer in China, ZG Boiler keeps on technology innovation and development. The primary driving force for development of fluidized bed combustion is reduced SO2 and NOx emissions from coal combustion. As the technology developed, it became apparent that the process could efficiently burn biomass and other low-grade fuels that are difficult or impractical to burn with conventional methods.
