Coal-saving combustion-supporting additive

Abstract

The invention provides a coal-saving combustion-supporting additive which is composed of the following components: 12-18wt% of combustion supporting agent, 35-58wt% of oxidant, 8-22wt% of fluxing agent, 8-20wt% of dispersant, 3-8wt% of sulfur fixing agent and 2-5wt% of carbon fixing agent. The addition of the coal-saving combustion-supporting additive can save coal by 12-18wt% and greatly reduce the discharge of sulfides and carbides.

Description

technical field [0001] The present invention relates to a kind of fuel combustion additive, more specifically, relates to a kind of coal combustion additive. Background technique [0002] my country's energy is dominated by coal, so far, it can account for more than 70% of the primary energy composition. With the global energy shortage and the increasingly serious environmental pollution, energy conservation and emission reduction have become one of the problems that must be faced in the economic development of all countries. Most of the coal in my country is formed by the alternate deposition of sea and land, and the sulfur content is generally high. After combustion, the main pollutants emitted into the atmosphere are sulfur dioxide, soot particles, nitrogen oxides and carbon monoxide. According to statistics, for a long time, due to insufficient combustion of coal in various boilers, it has not only caused a lot of waste of resources, but also seriously polluted the envi...

Problems solved by technology

[0003] It is understood that the 2010 National SO 2 Emissions are as high as 25 million tons, NO X Emissions are estimated to be more than 20 million tons, CO, CO 2 The emission is as high as more than 50 million tons. Every year, the country suffers from acid rain, SO 2 and CO, CO 2 The economic loss caused by pollution is tens of billions of yuan, and the impact on acid rain, SO 2 , NO X and CO, CO 2 Pollution control, currently there are hundreds of desulfurization, degassing and decarbonization technologies developed by countries all over the world, but less than 10% of them can be applied commercially. Some of them have large investment, low function, and poor removal effect, and some are difficult to apply on development
