Description
Technical field
The present invention relates to a kind of coal-saving agent.
Background technology
Coal is mainly graded elementary composition by carbon, hydrogen, oxygen, nitrogen, sulphur, phosphorus, water and ash, carbon, hydrogen, oxygen summation account for more than 95% of organic matter, and brown coal, bituminous coal, these several kinds classification of hard coal are arranged.Wherein pit ash divides inherent ash and external ash content.External ash content can be removed when coal separation, and inherent ash is high more, and the washability of coal is poor more.Ash content increases in the steam coal, and thermal value reduces, and bed drain purge increases, the easy slagging scorification of coal.General ash content increases by 2%, and thermal value reduces about 100 kilocalories/kg.The every increase by 1% of ash content, coke strenth descends 2%, boiler for producing ability drop 3%, amount of lime increases by 4%.By 2010, the maximum coal consumption state in the whole world was a China, accounts for 35% of global consumption.And the big province of the producing coal as the Heilongjiang Province, old industrial bases has become reversal of the natural order of things with coal, so the problem of how to economize on coal is very urgent.
Coal divides several kinds of brown coal, bituminous coal (one, two, three type), hard coal (, two, three type), mud coal, meager coals etc.The Northeasts such as Heilungkiang, Jilin, Liaoning are commonly used is three kinds in brown coal, bituminous coal, mud coal.Its metabituminous coal ash oontent is higher.Different its one-tenth of the kind of coal are grouped into different with quality, and thermal value (unit mass fuel combustion liberated heat is called thermal value) is also different.
1) brown coal: be mostly block, be chocolate, gloss is dark, and quality is loose, contains volatile matter about 40%, and burning-point is low, catch fire easily, and quick combustion during burning, flame is big, over-emitting black exhaust, carbon content and thermal value are lower, and combustion time is short, needs frequent coal.
2) bituminous coal: be generally granularly, powdered is also arranged, many black in color and glossy contain volatile matter more than 30%; Burning-point is not too high, and carbon content and thermal value are higher, quick combustion, and flame is long; A large amount of black smokes are arranged, and combustion time is long, and most of bituminous coal toughness are prone to slagging scorification during burning.
3) mud coal: carbonizing degree is the most shallow, and carbon content is few, and moisture content is many, and MAR can need open-air air-dry back to use up to 90%, and thermal value is extremely low.
Most enterprises are a kind of, two kinds even three kinds of coals mix use simultaneously, and its reason is very simple.1) adds bituminous coal for reducing brown coal short problem combustion time, though the adding of bituminous coal has prolonged combustion time, produced the phenomenon of large-area coking, and generated sulfurous gas, corroding metal, contaminate environment.2) lower and be difficult to fully collect because of the charge of business capital anxiety and heating enterprise, so enterprise has to adopt a part of carbon content seldom but the very cheap mud coal of price.Therefore adopt the coal-saving agent of efficient, environmental protection, decoking that enterprise is seemed very necessary.
Summary of the invention
The present invention seeks to solve enterprise with the bulk coking problem that is produced in coal cost height and the combustion processes, and a kind of combustion-supporting decoking coal-saving agent is provided.
A kind of combustion-supporting decoking coal-saving agent by weight mark by 4～10 parts of potassium permanganate; 2～6 parts of sodium-chlor; 10～12 parts of dimethylcarbinol-ethanol; 6～8 parts of Rare Earth Lanthanum; 3～5 parts of dispersion agents; 4～6 parts of calcium chloride; 1～2 part of high alumina vanadium scholar; 5～6 parts of olefin(e) acid one YLENE PEMULEN TR2s; 3～4 parts of hexones; 5～8 parts of Potassium peroxide 85s; 6～8 parts of polyoxyethylene 20 sorbitan monostearates; 4～6 portions of sulphur-fixing agents; 5～10 parts of Tween-60s; 2～3 parts of tributyl phosphates; 8～15 portions of DIPEs; 3～4 portions of scale removers and 5～8 parts of permeate agents mix.
Advantage of the present invention: the combustion-supporting decoking coal-saving agent that in coal, adds the present invention's preparation; The fire box temperature of different boiler houses has improved 100 ℃～300 ℃; Boiler slag carbon content reduces 30%～40%; The flue dust rate of removing can reach 40%～60%, and the obnoxious flavour rates of removing such as carbon monoxide, sulfurous gas can reach 30%～60%; Decoking effect: can be with hard 100cm
