Environment-friendly fire coal combustion improver

Abstract

The invention relates to an environment-friendly fire coal combustion improver. According to the combustion improver, calcium carbide waste residues, iron mineral powder, coal ash, certain chemical plant waste liquids and the like are taken as efficient composition of the fire coal combustion improver, and the fire coal combustion improver is prepared by blending the efficient composition with a few quantity of strong oxidants, catalysts, adhesives, swelling agents, rare earth compounds and the like. The main technical formula of the fire coal combustion improver is characterized by comprising components in percentage by mass as follows: 20%-40% of calcium carbide waste residues, 20%-40% of iron mineral powder, 10%-20% of coal ash, 20%-30% of alkaline plant waste liquids, 0.5%-2% of potassium permanganate, 5%-10% of sodium chloride, 0.05%-0.2% of cerium oxide and 0.2%-0.4% of fatty alcohol-polyoxyethylene ether. 2%-10% of the environment-friendly fire coal combustion improver is added and matched with raw coal for use, the sulfur fixation rate is higher than 60%, and the theoretical coal-saving rate can be 10%-25%; the fire coal combustion improver can be matched with inferior coal such as coal gangue and the like, the problems of high combustion point and insufficient combustion are solved, and combustion and utilization of inferior coal resources are reinforced; and certain industrially discharged solid waste is used as a combustion-supporting, sulfur fixation, nitrogen fixation, smoke prevention and dust control component of the combustion improver, and the environment-friendly fire coal combustion improver has very important practical significance in the aspects of energy saving and environmental protection.

Description

technical field [0001] The invention relates to an environment-friendly coal-burning combustion aid and its production formula. Background technique [0002] my country is the largest coal consuming country in the world. Coal accounts for about 70% of primary energy consumption. It is one of the few countries in the world whose energy consumption is dominated by coal. Moreover, my country's industrial boilers have outdated combustion equipment, backward combustion technology, and incomplete combustion. Make combustion efficiency low, energy waste is extremely serious. [0003] Coal resources are limited and storage capacity is decreasing, but the demand for coal in social development is increasing day by day. With the rapid development of China's economy, the energy consumption per unit of GDP has once increased and the resulting high pollutant emission intensity has restricted the sustainable development of the social economy. Therefore, no matter from the perspective of e...

Problems solved by technology

[0005] At present, some commercial coal-fired combustion-supporting agents have been launched in China, which have produced good results, but the cost is high, and due to the complexity of coal composition and coal combustion process, the combustion-supporting effect is inconsistent, and the promotion is limited
