Abstract
An efficient environmentally friendly fuel coal additive is prepared from calcium oxide (10-30 pts.wt), potassium permanganate (3-15 pts.wt.), MnO2 (3-15 pts.wt.), magnesium oxide (1-5 pts.wt.), potassium chloride (1-5 pts.wt.) and barium nitrate (1-5 pts.wt.). It can increase the heat number of fuel coal and greatly decrease the exhaustion of harmful gas and smoke.
Description
The present invention relates to additive, specifically a kind of additive that improves combustionproperty at fire coal.
On coal exploitation utilized, what at first will solve was to improve combustion efficacy, improves thermal value, reduces pollution exhaust criteria, to adapt to the needs of various burning occasions; Next is only utilizes the refuse of opening a mine (as spoil, oil shale, slag ...) problem such as processing.Fuel for equipment claimed such as industrial used boiler, kilns is the higher fat coal of thermo-efficiency, if reducing coal, long calorific value of low grade coal and accumulation time do not reach combustion efficacy, need take combustion-supporting measure, but effect is still undesirable, and how to solve low grade coal raising combustion efficacy is the problem that relevant department very pays close attention to always.
The purpose of this invention is to provide a kind of additive for fire coal that makes low grade coal and the lower fire coal of thermo-efficiency improve combustion efficacy.
The object of the present invention is achieved like this:
Get 10～30 parts in calcium oxide, 3～15 parts in potassium permanganate, 3～15 parts of Manganse Dioxide, 1～5 part in magnesium oxide, 1～5 part in Repone K, 1～5 part of formation of nitrate of baryta additive formula by weight.
6 kinds of given materials are crossed 60 mesh sieves and are mixed through fragmentation and are dissolved in 8～10 times of water, and formation additive solution at normal temperatures stirs.Additive is sprayed coal-fired surface, coal-fired thermo-efficiency is improved.
The present invention is a kind of advanced person's cleaning, a modification additive for fire coal.In fire coal, add this additive by a certain percentage, carry out in the combustion processes, can realize cleaning, modification burning at boiler.From the environmental protection aspect, can reduce smoke discharge amount more than 95%, obnoxious flavoures such as reduction sulfurous gas are realized cleanburning more than 40%; From improving the calorific value aspect, help oxygen, catalytic modification combustion technology owing to adopt, can make coal-fired by about 1000 kilocalories/kilogram of former thermal value raisings, even can make aphlogistic coal gangue and nonflammable low grade coal realize normal fully burning, by improving the effect of flame temperature and a large amount of water-gas of generation, its comprehensive combustion effect also can improve the production capacity of 1000 kilocalories of/kilogram calorific values.Putting into operation of this product will make coal gangues a large amount of in the China's coal-mine, coal slime, low grade coal be able to sufficient utilization, can realize that two class bituminous coal (3500 kilocalories/kilogram～4700 kilocalories/kilogram) reach the combustion efficacy and the production capacity effect of fat coal.This has great economy and environmental benefit to the sustainable development of coal in China industry.Environment-protecting efficient additive for fuel coal is nontoxic, pollution-free, nonflammable, non-explosive, the pH value is neutral, and no obnoxious flavour produces in the combustion processes, to the boiler non-corrosiveness.
Maximum characteristics of the present invention are obvious social benefit, the business economic considerable benefit, can be described as sharp in contemporary merit in eternal lasting.In the additive is to pay product more than 50%, cheap, wide material sources.
Embodiment:
1. get 15 parts in calcium oxide, 10 parts in potassium permanganate, 5 parts of Manganse Dioxide, 2 parts of manganese oxide, 3 parts in Repone K, 3 parts of nitrate of baryta by weight, cross 60 mesh sieves and mix through fragmentation and be dissolved in 8 parts of water the formation that stirs additive.The surperficial formed fire coal of the raw coal that additive sprays (low grade coal, mixing coal, long coal of accumulation time), aspect calorific value, can improve 1000 kilocalories/kilogram, the quantity discharged of sulfurous gas can be controlled in below 0.7 during burning, oke exhaust blackness can be reduced to 0.1～0 grade by Lin Geman more than 3 grades, coal ash can be controlled in below 20%.
2. get 20 parts in calcium oxide, 12 parts in potassium permanganate, 10 parts of Manganse Dioxide, 3 parts of manganese oxide, 3 parts in Repone K, 3 parts of nitrate of baryta, fragmentation is dissolved in 10 times of water after crossing 60 mesh sieves, stirs well the formation additive.
This additive can be prepared with any coal:
(1) be suitable for fat coal, prepare this additive after, not only can improve calorific value, and can reduce obnoxious flavour and smoke discharge amount greatly.
(2) be suitable for low grade coal, can improve 1000 kilocalories/kilogram combustion efficacy and production capacity effect after preparing this additive.For example: can be increased to 3700 kilocalories/kilogram～4100 kilocalories/kilogram behind 2900 kilocalories/kilogram～3200 kilocalories/kilogram the raw coal additive preparation, thermo-efficiency improves 25%～30%, save raw coal 30～50%, sulphur content is reduced to below 0.7% by 1.0%, dirt and 3.4 benzopyrenes reduce more than 95%, and lingemann blackness drops to 0.1～0 grade by 3～5 grades.
(3) be suitable for a underproof class bituminous coal (2000～3400 kilocalories/kilogram).If the aphlogistic waste coal that is mixed with a large amount of coal gangues in the coal or piles up throughout the year, burning can't be used separately, but add this additive after preparation rationally can realize sufficient burning, and can improve 1000 kilocalories/kilogram production capacity effect, realize utilization of waste material.
(4) preparation mixes coal, 5000 kilocalories/kilogram raw coal can be mixed 30～40% anthracites, coal gangue, coke powder etc. are mixed, also can realize sufficient burning after adding this additive, reach the combustion efficacy of two class bituminous coal, thereby realize the quantity discharged that utilization of producing and reduction flue dust are arranged of kitchen range spoil resource.
(5) be suitable for various moulded coals, adopt this additive technology standard coals (20～40%) such as a large amount of coal gangues, coal slime, low grade coal can be carried out being mixed of different ratios, the moulded coal of different performance and purposes be can produce, standard type burning of coal effect and production capacity effect reached.Simultaneously can also a large amount of quantity dischargeds that reduce obnoxious flavour and flue dust.
Claims (2)
1. an environment-protecting efficient additive for fuel coal is characterized in that getting by weight 10～30 parts in calcium oxide, 3～15 parts in potassium permanganate, 3～15 parts of Manganse Dioxide, 1～5 part in magnesium oxide, 1～5 part in Repone K, 1～5 part of formation of nitrate of baryta additive formula.
2. the preparation method of the described environment-protecting efficient additive for fuel coal of claim 1 is characterized in that 6 kinds of given materials are crossed 60 mesh sieves and mixed through fragmentation to be dissolved in 8～10 times of water, and formation additive solution at normal temperatures stirs.
