Abstract
The present invention relates to a high-efficient environmental protection additive for coal, which comprises the components according to parts by weight: 0.8 to 3.5 portions of potassium chlorate, 0.5 to 3.2 portions of potassium permanganate, 0.5 to 3.5 portions of quicklime, 0.8 to 3.2 portions of potassium nitrate and 0.8 to 2.8 portions of sodium nitrate. The present invention has the advantages that the coal heat efficiency can be greatly increased, the flames are increased, a combustion zone is lengthened, the carbon content of discharged slag is reduced, the coal is saved greatly, the discharge of poisonous and harmful gas is greatly reduced, the high-efficient environmental protection additive is favorable to environmental protection, a coke formation phenomenon at a furnace tail is greatly reduced, the coal is loosened, the combustion is complete and sufficient, the coal combustion time is prolonged, the cost of raw materials and production is reduced and the high-efficient environmental protection additive is convenient to popularize. By experiment indication, the positive balance rate of boilers using the high-efficient environmental protection additive for coal can be increased by 11.2%, the inverse balanced rate can be increased by 8.93%, gas heat loss due to incomplete combustion is clearly better, the air excess coefficient is descended and the CO content is reduced.
Description
Technical field
The present invention be more particularly directed to a kind of additive for fire coal.
Background technology
Fire coal be the most common also be one of topmost energy, it is widely used in industrial and mining enterprises and the daily life.Efficiency of combustion is low, the distinct disadvantage of contaminate environment but coal also has.Therefore, improve coal-fired efficiency of combustion, economize on coal purpose and reduce coal-fired pollution, become the important topic of current save energy environment thereby reach.At present, mainly take the method for interpolation additive for fire coal in fire coal to reach the purpose of economizing on coal.By adding additive for fire coal, can make fired coal combustion more abundant.But existing additive for fire coal energy-saving effect is not obvious, and is still very serious to environmental pollution, and the cost height.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of make fired coal combustion fully, prolong combustion time, increase substantially coal-fired thermo-efficiency, effect of coal saving is obvious, reduce the toxic and harmful quantity discharged, compliance with environmental protection requirements, the additive for fire coal that production cost is low, be convenient to promote.
Technical solution of the present invention is: consist of 0.8～3 part in 0.8～3.5 part in Potcrate, 0.5～3.2 part in potassium permanganate, 0.5～3.5 part of unslaked lime, 0.8～3.2 part in saltpetre, 0.8～2.8 part of SODIUMNITRATE, 8～20 parts in sodium-chlor, 0.5～2 part of hexamethylenetetramine, 0.5～2.5 part of anhydrous sodium sulphate and sodium hydroxide according to ratio of weight and number, thin up, the weight ratio of described water and said mixture are 1: 10～5: 10.
Advantage of the present invention is: as pour point depression, raising agent and have the Jiaozhuo of separating usefulness, sodium-chlor also has combustion-supporting effect with sodium-chlor, and as the carrier of other component; Unslaked lime (calcium oxide) is as sulphur-fixing agent, and saltpetre is as carburizing agent; Hexamethylenetetramine has hydrolysis, addition reaction effect.Therefore, this additive for fire coal can increase substantially coal-fired thermo-efficiency, and flame is increased, and the combustion district prolongs; The carbon content of slagging tap is reduced, economize on coal significantly; The toxic and harmful discharging significantly reduces, and is environmental; The burnt phenomenon of stove caudal knot is significantly reduced, and become more loose; Burning fully, fully prolongs the combustion time of coal; Raw material itself is nonflammable non-explosive, and is nontoxic, and production cost is low, is convenient to promote.Our experiments show that adopt the boiler of this additive for fire coal, the positive balance rate can improve 11.2%, anti-balance ratio can improve 8.93%, and gas the heat loss due to incomplete combustion take an evident turn for the better, and coefficient of excess air descends, and CO content reduces.
