Abstract

The invention belongs to the technical field of boiler anti-coking treatment, in particular to a boiler anti-coking and anti-corrosion treatment agent and a preparation method and application thereof. Including 3-5 parts of zirconia, 5-10 parts of refractory fine soil, 3-5 parts of sodium soil powder, 11-13 parts of silicon carbide, 13-15 parts of boron nitride, 20-25 parts of brown corundum, and 1.5- parts of cobalt oxide 2 parts, 10-15 parts of chromium oxide green, 10-12 parts of aluminum oxide, 10-12 parts of phosphoric acid solution, 5-6 parts of aluminum dihydrogen phosphate solution, 0.8-1 part of graphene, 1-2 parts of carboxymethyl cellulose parts, 15-17 parts of water. The method provided by the invention enables the surface of the object to have a stronger ability to absorb and radiate heat by coating the surface of the heating surface with a layer of material with extremely nano-scale particle size and high emissivity, so as to improve the heat transfer efficiency of the object and solve the problem of boilers. A treatment method for coking, which can effectively alleviate and inhibit boiler coking, and ensure high-load, economical, safe and stable operation of boilers. The method has low cost, simple implementation and extremely obvious effect.

Description

technical field [0001] The invention belongs to the technical field of boiler anti-coking treatment, in particular to a boiler anti-coking and anti-corrosion treatment agent and a preparation method and application thereof. Background technique [0002] Some existing power plant boilers have different degrees of coking and slagging, and some power plants are forced to reduce boiler output by 10%-20% and thermal efficiency by 1%-2.5% due to serious coking. Because of coking in the furnace, the heat transfer resistance of the heating surface will increase, which will reduce the radiation heat absorption of the cold wall, increase the temperature of the flue gas at the furnace outlet, and affect the water circulation conditions, so that the convection heating surface will be overheated due to the increase in heat load; the burner Coking at the nozzle and its vicinity will change the jet flow and the dynamic conditions in the furnace, which will affect the mixing and combustion ...
