Abstract
The present invention relates to a combustion-supporting desulfurizing dust-eliminating coal-combusting particle, which is composed of the ingredients of the following weight percentages: 40 to 50% part of coal and 10 to 20% part of an additive, wherein the additive is composed of the ingredients of the following proportion of parts by weight: 70 to 85 parts of clay, 5 to 15 parts of CaO2-5, NaOH2-5 and a chemical combustion improver. A combustion improver is composed of one or more of the ingredients of the following proportion of parts by weight: 1 to 4 parts of aluminum hydride solution, 1 to 2 parts of potassium perchlorate, 2 to 4 parts of potassium hypermanganate, 1 to 2 parts of potassium nitrate and 5 to 10 parts of sodium nitrate. The granulating coal can reduce the content of fly ash in smoke; particles of the granulating coal are uniform, and have consistent combustion speed and wind resistance on a grate; the condition of air distribution can be effectively improved. Simultaneously, a combustion zone is more convenient to control. The granulating coal can be combusted in the dry state, so the heat which is absorbed by mixed water of combusted coal is reduced.
Description
Technical field
The present invention relates to a kind of combustion-supporting desulfurization and subtract the dirt particle.
Technical background
At present, widely used coal firing boiler great majority adopt traveling-grate stoker in the industrial and mineral enterprises and institutions of urban and urual areas of whole country, between the fire grate segment owing to ventilate, technical requirementss such as transmission must be in certain clearance, the used fire coal of boiler, crossing particle 6mm-25mm with sub-sieve is advisable, by the following broken coal proportion of technical requirements 6mm is below the 50%-55%, yet, actual fire coal of reaching the spot, the following broken coal proportion of 6mm is all more than 70%, indivedual even reach 80%-90%, and the broken coal below 3 occupies sizable share, because it is a lot of that the broken coal amount exceeds technical requirement on design, there are the following problems to use above-mentioned coal: 1, containing the combustiblematerials amount in flying dust amount and the flying dust increases; 2, fire grate leaks the on-the-spot measuring and calculating of coal at 12%-18%; 3, the fine coal too high levels causes the coal-supply system Dust Capacity big, and the environmental health situation worsens; 4, comprehensive utilization of energy rate is low, and waste of fuel is serious; 5, dust-removal system work worsens, and the flue dust that discharges to air very easily exceeds standard.
Technical problem to be solved by this invention provides a kind of coal-fired particle that collects combustion-supporting, desulfurization, subtracts dirt usefulness.
The present invention adopts following technical scheme: the present invention is made of following ratio of weight and number component: coal 40-50 part, additive 10-20 part; Described additive is made of following ratio of weight and number component: clay 70-85 part, CaO 2-5 part, NaOH 2-5 part and chemical ignition dope 5-15 part; Described ignition dope is by one or more mixed the forming in the following ratio of weight and number component: sodium chlorate 1-4 part, potassium perchlorate 1-2 part, potassium permanganate 2-4 part, saltpetre 1-2 part, SODIUMNITRATE 5-10 part.
Positively effect of the present invention is as follows: the coal-fired particle of the present invention can make chain fire-gate coal leakage quantity reduce to below 2%, even reach zero leakage coal.Contained chemical ingredients has combustion-supporting effect in the additive, thereby burning is strengthened, contained chemical ingredients energy and the sulfur in smoke of additive reacts, thereby the content of sulfur dioxide in the flue dust is reduced greatly, can reduce flue dust to a great extent the pollution of atmospheric environment and dedusting water to water resource environment.Prilled coal can reduce fly ash content and prilled coal uniform particles in the flue dust, and the combustionvelocity on fire grate, windresistance unanimity can effectively be improved the air distribution condition, simultaneously, the dry state operation can be realized in convenient control combustion zone, prilled coal, has reduced the heat that absorbs because of coal-fired water mixing.
