Coal-saving decarburization combustion improver

Abstract

The invention discloses a coal-saving decarburization combustion improver. The improver is prepared by evenly mixing the following components by weight percent: 20-30% of activated calcium oxide, 9-12% of magnesium hydroxide, 12-20% of sodium carbonate, 8-10% of activated carbon, 12-15% of FeSi powder, 8-12% of manganese dioxide, 3-5% of strontium carbonate and 5-7% of barium hydroxide. By adding the combustion improver of the invention in fire coal, the dosage of coal can be reduced by 2-15%, the thermal efficiency can be increased by 0.5-5%, and the decarburization effect is good.

Description

technical field [0001] The invention relates to a coal-saving decarbonization combustion aid. Background technique [0002] my country's SO 2 , NO X and CO, CO 2 The emissions are among the highest in the world, and the air pollution and acid rain caused by them are very serious, and the economic losses are huge, which have become the main factors restricting the sustainable development of my country's economy and society. Therefore, the control of SO 2 , NO X and CO, CO 2 Pollution is inevitable. [0003] It is understood that the 2008 National SO 2 Emissions up to 25.49 million tons, NO X The preliminary estimate of emissions is 22.2 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, ...

Problems solved by technology

[0003] It is understood that the 2008 National SO 2 Emissions up to 25.49 million tons, NO X The preliminary estimate of emissions is 22.2 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 have large investment, low function, poor removal effect, and some are difficult to apply in the world on development
