Problems solved by technology

Once slagging and contamination are formed, due to the low thermal conductivity of ash and slag, it will reduce the heat absorption in the boiler furnace, which will not only reduce the thermal efficiency of the boiler, but also limit the load of the boiler, thereby destroying the overall heat balance process in the furnace, and even causing forced Accidents of boiler shutdown directly affect the safety, economy and reliability of boiler operation

Abstract

The invention relates to the technical field of the fine chemical engineering, and concretely relates to an anti-coking energy-saving agent for a coal-fired boiler. The anti-coking energy-saving agent for coal-fired boiler comprises, by weight, 15-28 parts of calcium formate, 15-23 parts of potassium permanganate, 10-18 parts of calcium hydroxide slag, 3-5 parts of magnesium chloride, 8-12 parts of silica, 3-4 parts of quartz powder and 1-3 parts of N-methylaniline. The anti-coking energy-saving agent for coal-fired boiler, provided by the invention, has the advantages of ideal effect and manpower saving.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to an anti-coking and energy-saving agent for coal-fired boilers. Background technique [0002] When coal-fired utility boilers burn, the minerals in the coal form soot. Due to the high thermal intensity, high combustion temperature and low ash melting point of coal-fired boilers, coal ash in molten and semi-molten state usually deposits and sticks on the heating surface of the boiler in the form of coking and contamination. Once slagging and contamination are formed, due to the low thermal conductivity of ash and slag, it will reduce the heat absorption in the boiler furnace, which will not only reduce the thermal efficiency of the boiler, but also limit the load of the boiler, thereby destroying the overall heat balance process in the furnace, and even causing forced Accidents of boiler shutdown directly affect the safety, economy and reliability of boiler operation. The ...
