Description
Technical field
The invention belongs to the environmental protection and energy saving technical field, relate to a kind of coal-fired composition, being specifically related to a kind of utilization has the coal-fired composition of bituminous coal for component.
Background technology
Coal occupies an important position in energy structure as basic energy resource, is divided into steam coal and coking coal according to its application target.Be divided into as the steam coal of fire coal bituminous coal and hard coal are arranged, the bituminous coal sulfur-bearing is arranged, hard coal is sulfur-bearing not.Just because of the existence of sulphur, making has bituminous coal in combustion processes, produces a large amount of dense smoke and floating matter, and environment is polluted.
In recent years, in order to improve the air pollution problems inherent that is on the rise, country prohibites and does not allow directly to use that bituminous coal is arranged.But China's hard coal skewness, long-distance transport causes it to hold at high price, and especially in the winter time the heating phase, hard coal can't be ensured supply.And China have the reserves of bituminous coal big, have a very wide distribution, particularly at northern area, thermal value has the storage capacity of bituminous coal quite big 5500 kilocalories～8000 kilocalories high-quality.According to investigations, general civilian and heating boiler coal, thermal value has bituminous coal at 4000 kilocalories～5000 kilocalories if these boilers directly use, and will certainly produce a large amount of dense smoke and floating matter, and environment is caused very big pollution.
Present moulded coal manufacturing firm mostly adopts chemical additive to carry out desulfurization and smoke elimination, facts have proved, use the chemical additive desulfurization, can reach the desulfurization standard of country, but can not reach the emission standard that national environmental protection allows but eliminate smoke, and the cost of additive is too high, make the price of final moulded coal also raise, be unfavorable for applying.
Summary of the invention
The object of the present invention is to provide the coal-fired composition of environmental protection and energy saving, utilizing has bituminous coal to be component, has not only realized the purpose of desulfurization, can not produce thick smoke and floating matter in combustion processes, and keep thermal value more than 4500～5000 kilocalories.
A kind of technical scheme of the present invention is, utilize the environmental protection and energy saving quick burning coal composition of bituminous coal for component, by mass percentage by forming by bituminous coal, desulfurizing and smoke eliminating ignition dope and oxygen enriching burning-aid agent, described oxygen enriching burning-aid agent is a potassium permanganate, and potassium permanganate occupies 0.02%～0.04% of bituminous coal by mass percentage.
Another technical scheme of the present invention is, utilize the environmental protection and energy saving quick burning coal composition of bituminous coal for component, by mass percentage by forming by bituminous coal, coal slime or soil, desulfurizing and smoke eliminating ignition dope and oxygen enriching burning-aid agent, described coal slime or soil occupy 40%～45% of bituminous coal by mass percentage, described oxygen enriching burning-aid agent is a potassium permanganate, and potassium permanganate occupies 0.02%～0.04% of bituminous coal by mass percentage.
The invention has the beneficial effects as follows:
1. according to the demand of burner, the thermal value in the time of can artificially between 5500 kilocalories～8000 kilocalories, regulating coal combustion, per ton have bituminous coal can produce 1.1 tons～1.3 tons fire coals, rationally uses the energy, reaches purpose of energy saving.
2. when burning, form secondary combustion, the inverse amplification factor of flue dust reaches 80%～90%.Simultaneously, do not expand in the combustion processes, not explosion, keep block, no floating matter discharge to perfect combustion.
3. can light with waste paper, need not to use timber to ignite.
In burner spontaneous firing effectively to stay fire be 80 minutes～90 minutes the time, the fire time of staying than original bituminous coal increases more than 1/3rd, the heat energy utilization rate of spontaneous firing reaches more than 90%, heat energy utilization rate than original bituminous coal has improved more than 30%, and the residue after the burning has reduced more than 15% than original bituminous coal.
