Abstract

The invention provides a multifunctional coal burning additive and an application thereof. The additive is prepared by compounding a natural macromolecular organic compound and natural ore rich in aluminate and silicate and having sponge-shaped structural pores as a carrier and a multi-element compound. The additive is of a double-carrier system, and meanwhile has functions such as burning assistance, sulfur fixation, smoke elimination, dust removal, decoking, corrosion inhibition; moreover, the using dosage is small and accounts for 0.1 to 0.15 percent of the coal burning amount, the multifunctional coal burning additive is easy to add, simple in process and low in cost, a cost-benefit ratio reaches 1: 6 or higher, the production cost is low, the economic benefit is good, and the market advantage is high.

Description

technical field [0001] The invention relates to the technical field of coal energy, and more specifically relates to a multifunctional coal-burning additive and its application. Background technique [0002] The issue of energy crisis has become the consensus of all countries in the world, and it is also an important strategic issue for our country. Coal is one of the main energy sources in our country. Even today, the utilization rate of coal is low, the phenomenon of waste is serious, and problems such as environmental pollution are caused. Lack of awareness still exists. At present, due to overproduction, the country has taken measures to destock the coal industry from the perspective of supply-side macroeconomics, which is correct. But overproduction is temporary. From a long-term strategic perspective, how to improve the efficiency of coal use, reduce environmental pollution emissions, and reduce the harm of smog to life, the people of the country should not relax at a...
