AI Technical Summary

Problems solved by technology

The current traditional coal-saving rate [combustion enhancer] is generally low, the emission reduction project is single, and the effect is not good, especially in the boiler furnace denitrification technology is backward, which is far from meeting the requirements of energy saving and emission reduction goals

Abstract

The invention relates to a fire coal synergist which is mainly prepared by multicomponent complex formulation of the following components: a modifier, a catalyst, a combustion promoter, a high-temperature sulfur-fixation auxiliary agent, a denitration agent, a smoke suppressor, a descaling scorch retarder and the like; during using, the synergist is added with an amount of 0.2% of the fire coal amount; and the synergist can modify the fire coal, catalyze the combustion, thus greatly increase the flame temperature and the flame amount, reduce the discharge of SO2 and NOX, reduce flue gas blackness, increase boiler heat efficiency, decrease coal consumption, increase the boiler service life, reach the purposes of energy saving and emission reduction, and has significant economic benefit and social benefit.

Description

technical field [0001] The invention relates to a coal-burning synergist, which is suitable for adding to bed-fired boilers, fluidized bed furnaces, circulating fluidized bed boilers, various industrial kilns, iron ore powder sintering machines, coal-water slurry boilers, cement calcining kilns, and gas generators In power coal blending, briquette coal, powder coal or coal water slurry. Background technique [0002] Coal is the main energy source in our country. With the development of the economy, its coal consumption is constantly increasing. For the purpose of saving coal and protecting the environment, there have been a large number of combustion accelerants, sulfur fixers, and soot removers, such as Chinese patent CN1041609 and Japanese patent No. 62-21400, etc., but from a social point of view, they all have common The weakness of the additive is that the function of the additive is single, the coal saving rate is low, and the SO 2 , NO X , dust and other emission ...
