Mechanism and Impact of US-Solid Additive on Performance of Coal-Combustion

The composition and phase of the US-solid additive and its impact on theperformance of coal combustion are investigated by using ICP-AES and other modern advanced tests and techniques in this paper.The results show that the US-solid additive has three different functions,i.e.combustion-supporting,catalytic and sulfur-fixed agent,in coal-burning boilers.By using US-solid additive,the performance of coal-combustion in the boiler has been improved notably by means of increasing the quantities of volatile matter and decreasing the ignition point and the time for starting fire.The US-solid additive,therefore,is conducive to ensuring that the coal in the boiler is burned completely.Thus,the density of flue dust and sulfur dioxide emitted from the coal-burring boiler with US-solid additive can be controlled and decreased markedly.
