The briquette is positive combustion honeycomb bituminite briquette and can be normally and completely combusted in a civil honeycomb briquette stove as smoke-less coal briquette; the discharge amount of carbon monoxide and sulfur dioxide in the smoke is lower than that of honeycomb briquettes of smoke-less briquettes; the present invention is in accordance with the established quality standard GB6412-86 of civil briquettes in China, the average briquette strength is 13KN, the combustion efficiency is 36%, and the average evaporation capacity is 4 g of 1g of briquettes; the defects of difficult combustion and difficult briquette exchange of reverse combustion bituminite briquettes are overcome. The present invention has the advantages of convenient use and high heat value.
Description
Technical field
The present invention relates to a kind of civilian shaped coal of bituminous coal, relate in particular to a kind of honeycomb bitumite briquet for smoke-less combustion in right direction.
Background technology
Because bituminous coal volatile content height burns under the anoxybiotic condition, can discharge a large amount of black smokes, these black smokes mainly comprise unburnt hydrocarbon polymer, CO and CO
2And fine particle carbon.In the prior art,, adopt the coal combustion technology of back-firing type mostly in order to realize the bituminous coal smokeless combustion.During burning, the exsiccant honeycomb briquette is put into honeycomb briquette stove, add an igniting cake then on the stove upper strata, light the bituminous coal honeycomb briquette; From top burning, progressively lighted earlier by following honeycomb briquette for coal, and the bituminous coal fugitive constituent is separated out from the top down successively, thereby realize the bituminous coal smokeless combustion.Its shaped coal of bituminous coal is generally by bituminous coal, binding agent, and weighting agent and a spot of smoke of gunpowder agent are prepared from, and binding agent is a raw material with the clay, and weighting agent adopts coal gangue more.This kind shaped coal of bituminous coal greatly reduces the moulded coal calorific value owing to added excessive low-calorie material; And change the coal difficulty, and changing difficult grasp the on coal opportunity, fume emission is difficult to control to environmental requirement, and this technical application is poor.In addition, back-firing type bituminous coal honeycomb briquette generally is divided into three layers, is respectively an ignition layer from top to bottom, ignite layer and moulded coal body, and an ignition layer is made of charcoal and oxygenant, and the layer of igniting is made of oxygenant and hard coal and charcoal, and the moulded coal body is a bituminous coal.Three layers of one of the difficult one-tenth of this honeycomb briquette, and be difficult in the continuous smokeless combustion of realization on the domestic honeycomb coal stove.If adopt the combustion system of combustion in right direction to burn, shaped coal of bituminous coal then can be emitted a large amount of coal smokes, and fume emission is difficult to meet the requirement of country to coal briquette for civillan use.
Summary of the invention
The present invention is intended at the deficiencies in the prior art and defective, a kind of honeycomb bitumite briquet for smoke-less combustion in right direction is provided, make it as anthracite briquette, can on the domestic honeycomb coal stove, carry out trouble-free burning, overcome the burning of back-firing type shaped coal of bituminous coal and change the shortcoming of coal difficulty, and have advantage easy to use, that calorific value is high.
The present invention is achieved through the following technical solutions: a kind of honeycomb bitumite briquet for smoke-less combustion in right direction, it contains bituminous coal, binding agent, weighting agent and four kinds of components of smoke suppressor, it is characterized in that described binding agent adopts the mixture of starch and clay, weighting agent adopts flyash or flying dust, described smoke suppressor is a sodium-chlor, and this moulded coal also contains potassium permanganate, two kinds of components of sawdust powder, and the weight percent of its each component is respectively:
Bituminous coal: 50～70%
Binding agent: starch, 0.5-3%; Clay, 1～10%
Weighting agent: flyash or flying dust 2-10%
Smoke suppressor: sodium-chlor 1-5%
Potassium permanganate: 8～30%;
Sawdust powder: 2%～10%
With above-mentioned each component uniform mixing in proportion, and add an amount of water and stirred, with the moulding on civilian shaper of mixed material, dry naturally then, can obtain shaped coal of bituminous coal.
Above-mentioned honeycomb bitumite briquet for smoke-less combustion in right direction, its profile is cylindrical, and inner ventilation hole is done tapered, can play the effect of enriched air By like this, having utilize to increase the needed oxygen concn of burning, makes the fugitive constituent of separating out fast easily and the oxygen complete reaction of higher concentration.
Because the present invention adopts interpolation potassium permanganate to come needed oxygen content in the aftercombustion process as oxygenant, and utilizes the reaction of sodium-chlor as smoke of gunpowder agent catalysis cigarette carbon content in coal and oxygen.Thereby a large amount of black smokes that under the anoxybiotic condition, burn and discharged have effectively been avoided owing to bituminous coal volatile content height; Adopt flyash with certain carbon content or flying dust as weighting agent simultaneously, can improve the calorific value of shaped coal of bituminous coal.Therefore this moulded coal not only can carry out normal perfect combustion on the domestic honeycomb coal stove as anthracite briquette, burning back fume emission controls to environmental requirement easily, carbon monoxide and sulphur dioxide emission are lower than the hard coal honeycomb briquette in the flue gas, meet the coal briquette for civillan use standard GB6412-86 that country formulates; And overcome the defective that the coal difficulty is changed in the burning of back-firing type shaped coal of bituminous coal, have easy to use, the calorific value advantage of higher.
