The boiler goes out equipment to extinguish way, the request to extinguish equipment, can maximize the fuel chemical energy released transformed into thermal energy. In the ordinary steam boiler, liquid and gaseous fuels after the nozzle in the furnace space in suspension turns off. Quenching of the solid fuel: layer style off, the suspension is off, the cyclone is off and boiling extinguished.
Tiered off: fuel is put into the fixed or activities grate, the air down by the grate after grate gap through the fuel bed into the furnace, the most fuel in the fuel layer on the grate to stop extinguish small local fine-grained and precipitate from the fuel layer of combustible gases in the upper space of the fuel layer to stop off. Tiered off applies to solid fuel.
      The suspension is off (we use the word chamber combustion mode) fuel and air together with the via is off into the boiler and steam boiler furnace space side of the sports side is off. Gas, liquid and solid fuel suspension extinguished.
      The cyclone off: This is the application of a strong air flow driven by a boiler fuel particles in the rotating cylinder of the boiler is off off equipment. High speed secondary air into the cylinder, fuel (burning fine coal or pulverized coal, etc.) from the axial or cut from the cut to enter the heat of the fuel particles in the secondary air driven, move to the fire extinguished, and rotating the road, then discharged until the burn barrel outside so far. The cyclone furnace vertical and horizontal.
      Boiling off: on the terms of the quenching of the solid fuel, the fuel is broken to a certain size and then into the furnace, the coal particles are neither on the grate, nor with the air activities, but in a certain space within the furnace troubled stop extinguish.
      Industrial steam boiler coal layer burning is extinguished as the main way in power plant steam boiler is suspended extinguish the majority. Extinguish equipment on the boiler there are two very important concepts: a grate area of ​​heat intensity (meaning: the heat released by the corresponding fuel goes out of the unit grate area per unit time); furnace volume heat intensity (meaning: The corresponding heat released by the fuel goes out of the unit furnace volume per unit time). Various fuels in different extinguish the heat intensity of the hot strength of the grate area and furnace volume and the normal load required amount of fuel, you can be sure the grate area and furnace volume.
