Abstract
The present invention relates to an environmental protection and coal saving combustion supporting agent which is prepared from raw materials 0.15 to 2 of potassium nitrate, 0.2 to 5 of potassium permanganate, 25 to 40 of waste slag of sulphuric acid plants, 20 to 30 of waste slag in electrolytic copper plants, 15 to 20 of waste slag of electrolytic aluminum plants, 0.5 to 2 of industrial salt, 0.4 to 1.2 of oxalic acid and 5 to 15 of calcium oxide by weight. The potassium nitrate, the potassium permanganate and the oxalic acid are dissolved in 10 times of water to be made into spraying liquid; the rest raw materials are pulverized into 3mm of mixed grains; the spraying liquid is uniformly sprayed on the mixed grains, and the environmental protection and coal saving combustion supporting agent of the present invention is obtained. The present invention has the advantages of low manufacture cost and conspicuous effect. Experiments proves that when the environmental protection and coal saving combustion supporting agent of the present invention is used for industrial boilers, the coal can be saved by 15 to 22%, and simultaneously, the furnace chamber temperature of the industrial boilers can be raised by more than 150 DEG C. The present invention is suitable for the civil sporadic combustion coil and the coal for industrial boilers, cement plants, brick kiln plants and power plants.
Description
Technical field
The present invention relates to a kind of combustion-supporting agent for fuel coal of environmental protection and coal-saving, be applicable to the coal of various Industrial Boilers, cement mill, brickkiln factory, power plant and civilian diffusing burning.
Background technology
The fast development of China is faced with increasingly serious resource environment problem, and the basic energy resource consumption of China at present is serious day by day, and the utilization ratio of resource is low, exists serious waste, and save energy is an important topic of present social being.As the coal of one of basic energy resource,, brought unnecessary burden to national economy and people's lives because incomplete combustion has caused very big loss.
Summary of the invention
The purpose of this invention is to provide a kind of ignition dope that coal combustion is complete, reach the environmental protection and coal-saving purpose that makes.
Technical scheme of the present invention is: this kind economical and environmental-protective combustion improver, it is characterized in that, raw material by following weight parts is made, the waste residue 25-40 of saltpetre 0.15-2, potassium permanganate 0.2-5, vitriol works, the waste residue 20-30 in electrolysis copper work, waste residue 15-20, the industrial salt 0.5-2 of electrolytic aluminium factory, oxalic acid 0.4-1.2, calcium oxide 5-15; Saltpetre, potassium permanganate, oxalic acid is dissolved in 10 times the water and makes spray liquid, all the other raw material powder are broken into 3 millimeters composite grain, spray liquid evenly are sprayed on the composite grain get final product.
The waste residue in the waste residue of vitriol works, electrolysis copper work, the waste residue of electrolytic aluminium factory exist in existing factory in a large number, and these waste residues need not handled, and directly pulverize to get final product.Other raw material all can be purchased on market.
During use, this ignition dope is mixed with coal-fired, utilize the stirrer thorough mixing to use.Ignition dope and coal-fired blending ratio are: the amount that adds ignition dope in the bituminous coal is the 1-1.5% of bituminous coal; The amount that adds ignition dope in the hard coal is anthracitic 2%.
Oxygenant in this ignition dope, multiple metallic compound play cartalytic decomposition effect to the combustiblesubstance in the fire coal at a certain temperature, can progressively emit comburant oxygen again, and heat is emitted in the surfactivity increase when making coal combustion increases; And can play solid sulphur effect, generate solid-state sulfide (K
2S), thus not generating gasiform sulfurous gas plays environmental-protection function; Scrubbing simultaneously, remove boiler be heated outer field dust and dirt and burnt shape thing, make it to decompose afterfire and eliminate, thereby improve adopting hot coefficient and work-ing life of boiler.
The invention has the beneficial effects as follows that cost of manufacture is low, effect is obvious, all can play the ideal effect, only need add the 1-2% of coal-fired weight during use for the coal of high low-volatile.The experiment proved that this ignition dope is used for the Industrial Boiler 15-22% that can economize on coal, as former coal-fired every day of 20 tons boiler, add this ignition dope 1.5% after, can economize on coal every day 3.8 tons, coal saving rate be 19% simultaneously boiler hearth temperature can improve more than 150 ℃.
This ignition dope is applicable to the coal of various Industrial Boilers, cement mill, brickkiln factory, power plant and civilian diffusing burning.
