specific Embodiment approach 1

[0011] Specific embodiment one: this embodiment is a kind of combustion-supporting coke-removing coal-saving agent, by weight fraction by 4~10 parts of potassium permanganate, 2~6 parts of sodium chloride, 10~12 parts of dimethylmethanol-ethanol, 6 to 8 parts of rare earth lanthanum, 3 to 5 parts of dispersant, 4 to 6 parts of calcium chloride, 1 to 2 parts of high aluminum vanadium, 5 to 6 parts of alkene-xylene acrylic acid copolymer, 3 to 4 parts of methyl Isobutyl ketone, 5-8 parts of potassium peroxide, 6-8 parts of polyoxyethylene sorbitan monostearate, 4-6 parts of sulfur-fixing agent, 5-10 parts of Tween-60, 2-3 parts It is prepared by mixing tributyl phosphate, 8-15 parts of diisopropyl ether, 3-4 parts of descaling agent and 5-8 parts of penetrating agent.

[0012] The method of using the combustion-supporting coke-removing coal-saving agent prepared in this embodiment: add the combustion-supporting coke-removing coal-saving agent prepared in this embodiment to the c...

specific Embodiment approach 2

[0014] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the dispersant is polyethylene glycol 400. The other specific embodiments are the same.

specific Embodiment approach 3

[0015] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the sulfur-fixing agent is CaO. Other specific implementation modes 1 or 2 are the same.

Abstract

The invention provides a combustion-supporting decoking coal saving agent, relating to a coal saving agent. The invention aims at solving the problems that coal cost of an enterprise is high and a coked block is produced in a combustion process. The combustion-supporting decoking coal saving agent provided by the invention is formed by mixing potassium hypermanganate, sodium chloride, dimethylcarbinol-ethanol, rare earth lanthanum, dispersing agent, calcium chloride, high-alumina vanadine, olefine acid-dimethylbenzene acrylate copolymer, methylisobutylketone, potassium peroxide, polyoxyethylene sorbitan monostearate, sulphur-fixing agent, Tween-60, tributyl phosphate, diisopropyl ether, descaling agent and penetrant. The combustion-supporting decoking coal saving agent provided by the invention has the advantages that: firstly, after the combustion-supporting decoking coal saving agent is used, furnace box temperature is improved, slag carbon content is reduced, and dust and harmful gases such as carbon monoxide and sulphur dioxide are removed; and secondly, the combustion-supporting decoking coal saving agent provided by the invention also has decoking function, thus deslagging labour intensity is reduced, comprehensive fuel coal saving rate is 7-16%, and production cost is reduced. The combustion-supporting decoking coal saving agent provided by the invention is mainly used for preparing the coal saving agent.

Description

technical field [0001] The invention relates to a coal-saving agent. Background technique [0002] Coal is mainly composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, water, and ash. The sum of carbon, hydrogen, and oxygen accounts for more than 95% of the organic matter. There are lignite, bituminous coal, and anthracite. Among them, the ash content of coal is intrinsic ash and extrinsic ash. Extrinsic ash can be removed during coal preparation, the higher the intrinsic ash, the poorer the selectivity of coal. The ash content in thermal coal increases, the calorific value decreases, the amount of slagging increases, and the coal is prone to slagging. Generally, the ash content increases by 2%, and the calorific value decreases by about 100 kcal / kg. For every 1% increase in ash content, the coke strength decreases by 2%, the boiler production capacity decreases by 3%, and the limestone consumption increases by 4%. As of 2010, the world's l...
