Abstract
The present invention relates to a kind of coal saving and combustion supporting sulfur fixer, is to be made of by weight ratio following compositions: sodium oxalate 3-5, SODIUMNITRATE 15-40, magnesium nitrate 10-20, sodium-chlor 10-25, ammonium oxalate 5-15, aluminium powder 3-10, calcium hydroxide 20-40, calcium stearate 5-10, magnesium oxide 5-20; Method for making is after above each composition is pulverized, to put into mixer and fully stir, and is mixed and made into.Coal saving and combustion supporting sulfur fixer of the present invention this can make fire coal reduce sulfur dioxide emissions in combustion processes, when reaching the protection environment, can save fire coal again, reduces coal-fired cost.
Description
Technical field
The present invention relates to a kind of coal saving and combustion supporting sulfur fixer and method for making.
Background technology
China is maximum in the world coal production state and country of consumption, coal resources shortage in recent years, and energy shortage has become whole society's Focal Point of Common Attention.Also have owing to contain a large amount of sulfurous gas and dust in the flue gas that coal burning is discharged, caused great environmental pollution, China governments at all levels all attach great importance to problem of environmental pollution, and utilize various laws, rules to curb environmental pollution, also advocate each coal-fired enterprise simultaneously energetically and use low sulfur-bearing coal or use the environment protection clean moulded coal of handling through desulfurization to reduce coal-fired pollution to environment.
Summary of the invention
The purpose of this invention is to provide a kind of coal saving and combustion supporting sulfur fixer and method for making, coal saving and combustion supporting sulfur fixer this can make fire coal reduce sulfur dioxide emissions in combustion processes, when reaching the protection environment, can save fire coal again, reduces coal-fired cost.
A kind of coal saving and combustion supporting sulfur fixer is characterized in that it being to be made of by weight ratio following compositions:
Sodium oxalate 3-5, SODIUMNITRATE 15-40, magnesium nitrate 10-20, sodium-chlor 10-25, ammonium oxalate 5-15, aluminium powder 3-10, calcium hydroxide 20-40, calcium stearate 5-10, magnesium oxide 5-20;
In the above composition, sodium oxalate, magnesium oxide, calcium hydroxide, magnesium nitrate are combined to form solid sulphur, basylous action in reaction process, and can improve the solid sulphur activity of calcium base low temperature, and still have best captured sulfur result in the condition of high temperature; SODIUMNITRATE, sodium-chlor, ammonium oxalate, aluminium powder, calcium stearate play combustion-supporting effect.The aluminum oxide that the aluminium powder reaction generates can replenish acidic metal oxide share in the coal ash, and coal-fired ash fusion point is improved, and it is loose to reach lime-ash, noncoking.
The method for making of described coal saving and combustion supporting sulfur fixer, make by following steps:
1) above each composition separated pulverizing is become 40 orders-400 order, stand-by;
2) by the weight part of prescription requirement, with above-mentioned stand-by raw material after metering, put into mixer and fully stir, mix, deposit in the feed bin after stirring;
3) with the product that stirs in the feed bin through after the assay was approved, the pack packing is gone into stockyard.
The invention has the beneficial effects as follows:
1) high-efficient coal-saving, because product of the present invention has unique combustion-supporting effect, can make the fired coal combustion condition optimizing, make coal-fired burning cmpletely in burner hearth, thereby reduced coal-fired mechanical incomplete combustion and chemical incomplete combustion probability, improved coal-fired effective rate of utilization and boiler thermal output greatly, reached the purpose of energy-conservation province coal, after testing, product coal saving rate of the present invention reaches 21.48%;
2) captured sulfur result is remarkable, and product sulfur-fixing rate of the present invention reaches 72%, makes the concentration of the sulfurous gas in the coal-fired flue-gas and quantity discharged all reach below the state environmental emissioning standard;
3), can make noncoking behind the fired coal combustion owing to have in the product of the present invention and improve coal-fired fusing point component.
