rice husk boiler for power plant

Earlier this year, fast Boiler successful bidder Guan China Fortune Foundation Real Estate Development Co., Ltd. Gas rice husk boiler for power plant tender offers to other companies low nitrogen gas pipe 80 tons of steam boilers and steam 40 tons each in Taiwan, with the use of 1.5 million square meters to meet the heating demand. The introduction of various environmental policies throughout the country to improve environmental protection in all walks of life. Among the improvements, the reduction of nitrogen oxide (NOx) emissions as the primary problem.

What should pay attention to the rice husk boiler for power plant hot start? (L) Unit hot start, if the boiler is cold, the boiler should start operating program parameters cold start sliding manner. (2) a hot start, the steam turbine main steam parameters required turn red at a temperature greater than the high pressure cylinder inner wall temperature of 50 ℃, and there are 50 deg.] C superheat, but considering the safety apparatus to the boiler, a main steam temperature should be below the rated steam temperature value 50 ~ 60 ℃. (3) unit starts, if the boiler pressure should only after the ignition is turned on in a secondary, or bypass and valve to the air exhaust. (4) reheat steam inlet steam temperature should not exceed 400 ℃ :, if a bypass desuperheating water can not put into use, the main steam temperature not higher than 450 ℃. (5) due to the high hot start parameters, should be increased steam flow through, to avoid overheating the wall, adjust combustion.

Discharging means provided important flue flue gas after the rice husk boiler for power plant operation, it can help design well flue boiler to reduce emissions of about 10%. Master the flue gas boiler design requirements, and strictly enforced to ensure that their own boilers achieve low emissions, from environmental protection departments thorough investigation.

Steam rice husk boiler for power plants that usually use pressure controllers use two or three pressure controllers. One is to control the start-up and shutdown of the furnace, one to control the large, small fire conversion, and the other to be used as an overpressure protection.
