Abstract
The invention relates to a coal-saving combustion-supporting sulfur-fixing agent, which is characterized in that the coal-saving combustion-supporting sulfur-fixing agent is prepared from the following components by weight part: 40-60 parts of sodium nitrate, 15-20 parts of ammonium oxalate, 20-30 parts of aluminum powder and 5-10 parts of magnesium oxide. The coal-saving combustion-supporting sulfur-fixing agent can be widely applied to suburban and rural families for refrigeration cooling in summer and heating warming in winter. The coal-saving combustion-supporting sulfur-fixing agent has the advantages that sulfur dioxide emissions in the combustion process of coal can be reduced, the environment is protected, meanwhile the coal can be saved, and the coal cost is reduced.
Description
Technical field
The present invention relates to a kind of prescription of coal saving and combustion supporting sulfur fixer.
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 prescription that the purpose of this invention is to provide a kind of coal saving and combustion supporting sulfur fixer, coal saving and combustion supporting sulfur fixer can make fire coal in combustion processes, reduce Carbon emission, when reaching the protection environment, can save fire coal again, reduce coal-fired cost.
For achieving the above object; The present invention provides a kind of coal saving and combustion supporting sulfur fixer, it is characterized in that: said coal saving and combustion supporting sulfur fixer is made up of the SODIUMNITRATE (weight part) of 40-60, the ammonium oxalate (weight part) of 15-20, the aluminium powder (weight part) of 20-30, the Natural manganese dioxide (weight part) of 5-10.
The present invention has following technique effect: 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; Through detecting, 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 national requirements for environmental protection.Owing to have in the product of the present invention and improve coal-fired fusing point and form, can make noncoking behind the fired coal combustion.
Embodiment
To combine embodiment that the present invention is further specified below.
