Boiler-use coal combustion-supporting material formulation method

Abstract

The invention discloses a boiler-use coal combustion-supporting material formulation method. The material is composed of the components of, by weight, 50-70% of manganese ore, 10-20% of potassium carbonate, 5-20% of ammonium nitrate, 10-20% of aluminum powder, 10-20% of potassium chlorate, and 10-30% of a clinker sintering aid, wherein the total amount of the components is 100% by weight, and manganese dioxide content in the manganese ore is no lower than 40%. The raw materials of the material provided by the invention can be easily purchased in market. With the formulation, coal can be saved by more than 18%, and sulfur dioxide emission can be reduced by more than 90%.

Description

Technical field [0001] The invention belongs to the field of combustion-supporting technology, in particular to a coal-fired combustion-supporting assembly method for boilers. Background technique [0002] With the rapid development of the national economy, my country’s underground coal reserves are also tending to rapidly decrease. High-quality coal has a particularly serious decline due to over-exploitation and large-scale exports, while inferior high-sulfur coal like stones remains In China, its low calorific value and serious pollution have brought serious difficulties to industrial production and people's lives, and at the same time caused serious harm to the atmospheric environment. From the perspective of development and strategy, the problems of environmental pollution and energy scarcity have posed a serious threat to the survival and development of the people, and they must be solved. [0003] There are many types of coal-burning auxiliaries produced on the market, but th...

Problems solved by technology

The combined action of manganese ore and chemical admixture can reduce the ignition point of coal powder, increase the melting point of coal ash, and adjust the combustion atmosphere at high temperature to achieve the purpose of promoting the concentrated combustion of low-quality coal; but the chemical admixture used in nature It is relatively difficult to obtain, and the effect of coal combustion is very high in boilers. Therefore, a more ideal combustion-supporting combination method is needed, which can further reduce the ignition point of coal powder, improve the utilization efficiency of coal powder, and save coal more. , reduce harmful gas emissions
