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 chemical engineering materials, and specifically relates to a boiler decoking and ash-removing energy-saving agent. The energy-saving agent comprises the materials of, by weight, 10-30 parts of vermiculite, 10-20 parts of borax, 8-15 parts of quartz powder, 8-12 parts of silica, 5-7 parts of aluminum trioxide, 8-10 parts of manganese carbonate, 8-12 parts of calcium hydroxide slag, 2-6 parts of potassium permanganate, 10-20 parts of copper oxide, 4-8 parts of sodium molybdate, and 2-5 parts of magnesium chloride. The invention aims at providing a safe and reliable boiler decoking and ash-removing energy-saving agent with an ideal effect.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a boiler coke-removing, dust-removing and energy-saving agent. 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. ...
