Problems solved by technology

Tens of thousands of black chimneys emit black dragons into the sky every moment. Floating dust and acid rain cause an imbalance in nature and seriously damage people's health. On the one hand, the mineable resources of raw coal are in short supply; Technology is wasting a large amount of raw coal, and while burning raw coal, it is seriously polluting the air

Embodiment Construction

[0006] The present invention is further illustrated in conjunction with the examples. The present invention is composed of salt as a combustion aid and quicklime as an absorbent by mixing in an appropriate proportion. 4-10% of salt is mixed with 96-90% of quicklime, and the minimum of salt is 4%. It is economical and has a significant combustion-supporting effect. After weathering the quicklime, removing stones, and crushing, it is sieved through a 60-80 mesh sieve, and the crushed salt is added according to the above ratio, and it is fully stirred and packed in bags. Quicklime absorbs carbon dioxide in the air during the weathering process and becomes calcium carbonate. When the calcium carbonate burns with raw coal at a temperature above 825°C, it emits carbon dioxide and becomes calcium oxide. Calcium oxide absorbs the harmful gas sulfur dioxide emitted during the combustion of raw coal and becomes calcium sulfate. Calcium sulfate can be discharged with slag; quicklime calci...

Abstract

The invention relates to a burning coal additive that belongs to coal fuel additive technology field. The main feature is that mixes the salt combustion adjuvant and calcium oxide absorbent as the ratio of 4-10%:96-90%. The invention uses the combustion supporting and catalysis of Na and Cl that could be decomposed from melt salt. The CO2 from burning calcium oxide could absorb the SO2 from burning coal and finally form CaCO3. Thus, the aim of benefit for the environment would be achieved. It also has notable economical benefit and social benefit.

Description

technical field [0001] The invention relates to a coal-burning additive, which is an additive mixed in coal-fired and co-combusted, and belongs to the technical field of coal fuel additives. Background technique [0002] my country is a country that consumes a lot of energy, and it is also a country that is very short of energy resources. Relevant media have reported that my country consumed 30% of the world's energy in 2003, and raw coal alone consumed 1.579 billion tons, accounting for 3 / 4 of the total energy. Tens of thousands of black chimneys emit black dragons into the sky every moment. Floating dust and acid rain cause an imbalance in nature and seriously damage people's health. On the one hand, the mineable resources of raw coal are in short supply; Technology is wasting a large amount of raw coal, and while burning raw coal, it is seriously polluting the air. Contents of the invention [0003] The purpose of the present invention is to provide a fuel that is not ...
