Abstract
The invention discloses a combustion improver for pulverized-coal boilers and an application method thereof. The combustion improver is composed of the following components in parts by weight: 10-15 parts of magnesium chloride, 20-25 parts of potassium nitrate, 15-20 parts of sodium nitrate, 6-10 parts of potassium chlorate, 8-10 parts of sodium chlorate, 2-5 parts of ferric oxide, 2-5 parts of aluminum oxide and 2-5 parts of silicon oxide. The magnesium chloride, ferric oxide and silicon oxide in the combustion improver can prevent the pulverized coal from coking in the combustion process; and the potassium nitrate, sodium nitrate, potassium chlorate and sodium chlorate can be successively decomposed and release oxygen at different temperatures, and thus, can promote the complete combustion of the coal, thereby enhancing the boiler temperature and heat efficiency and lowering the emission of the pollutants.
Description
Technical field
The present invention relates to combustion adjuvant, especially, relate to a kind of combustion adjuvant for pulverized-coal fired boiler and using method.
Background technology
Pulverized-coal fired boiler is widely used in industrial circle, directly use coal-fired as combustion material, the pollutant such as a large amount of sulfide, carbon dioxide, carbon monoxide can be produced during fired coal combustion, especially burn insufficient in the case of, the pollutant of generation are even more serious；Meanwhile, furnace temperature and the thermal efficiency of pulverized-coal fired boiler can be substantially reduced, cause the waste of resource.The most how to promote that fire coal burns completely, and then improve the furnace temperature of pulverized-coal fired boiler, the thermal efficiency, reduce the disposal of pollutants of coal dust firing, the always research direction of industry.
Summary of the invention
Present invention aim at providing a kind of combustion adjuvant for pulverized-coal fired boiler and using method, to solve in prior art, coal dust firing is insufficient can produce a large amount of pollution, reduces the furnace temperature of pulverized-coal fired boiler and the problem of the thermal efficiency simultaneously.
For achieving the above object, the present invention provides a kind of combustion adjuvant for pulverized-coal fired boiler, is made up of the component of following parts by weight: magnesium chloride 10-15 part, potassium nitrate 20-25 part, sodium nitrate 15-20 part, potassium chlorate 6-10 part, sodium chlorate 8-10 part, iron sesquioxide 2-5 part, aluminium oxide 2-5 part, silicon oxide 2-5 part.
Further, it is made up of the component of following parts by weight:
12 parts of described magnesium chloride, described potassium nitrate 21 parts, described sodium nitrate 17 parts, 8 parts of described potassium chlorate, 9 parts of described sodium chlorate, described iron sesquioxide 3 parts, described aluminium oxide 4 parts, described silicon oxide 4 parts.
The present invention provides the using method of a kind of combustion adjuvant for pulverized-coal fired boiler: above-mentioned each component mix homogeneously is ground to form powdery, adds the ratio of 45-80kg combustion adjuvant in coal dust per ton, is mixed with coal dust by combustion adjuvant.
The method have the advantages that
Coking when magnesium chloride in combustion adjuvant, iron sesquioxide and silicon oxide are possible to prevent coal dust firing, potassium nitrate therein, sodium nitrate, potassium chlorate and sodium chlorate then can decompose the most successively and release oxygen, thus fire coal can be promoted to burn completely, and then improve boiler temperature and the thermal efficiency, reduce the discharge of pollutant.
Detailed description of the invention
Hereinafter embodiments of the invention are described in detail.
The preferred embodiments of the present invention provide a kind of combustion adjuvant for pulverized-coal fired boiler, are made up of the component of following parts by weight: magnesium chloride 10-15 part, potassium nitrate 20-25 part, sodium nitrate 15-20 part, potassium chlorate 6-10 part, sodium chlorate 8-10 part, iron sesquioxide 2-5 part, aluminium oxide 2-5 part, silicon oxide 2-5 part.
Further, it is made up of the component of following parts by weight: 12 parts of described magnesium chloride, described potassium nitrate 21 parts, described sodium nitrate 17 parts, 8 parts of described potassium chlorate, 9 parts of described sodium chlorate, described iron sesquioxide 3 parts, described aluminium oxide 4 parts, described silicon oxide 4 parts.
The present invention provides the using method of a kind of combustion adjuvant for pulverized-coal fired boiler: above-mentioned each component mix homogeneously is ground to form powdery, adds the ratio of 45-80kg combustion adjuvant in coal dust per ton, is mixed with coal dust by combustion adjuvant.
Embodiment 1
It is made up of following component: magnesium chloride 15kg, potassium nitrate 25kg, sodium nitrate 15kg, potassium chlorate 6kg, sodium chlorate 10kg, iron sesquioxide 2kg, aluminium oxide 5kg, silicon oxide 2kg.
Embodiment 2
It is made up of following component: magnesium chloride 12kg, potassium nitrate 21kg, sodium nitrate 17kg, potassium chlorate 8kg, sodium chlorate 9kg, iron sesquioxide 3kg, aluminium oxide 4kg, silicon oxide 4kg.
Embodiment 3
It is made up of following component: magnesium chloride 10kg, potassium nitrate 20kg, nitric acid 20kg, potassium chlorate 10kg, sodium chlorate 8kg, iron sesquioxide 5kg, aluminium oxide 2kg, silicon oxide 5kg.
During use, above-mentioned each component mix homogeneously is ground to form powdery, add the ratio of 45-80kg combustion adjuvant in coal dust per ton, combustion adjuvant is mixed with coal dust, burn in then coal dust is sent directly into boiler.Coking when magnesium chloride in combustion adjuvant, iron sesquioxide and silicon oxide are possible to prevent coal dust firing, potassium nitrate therein, sodium nitrate, potassium chlorate and sodium chlorate then can decompose the most successively and release oxygen, thus fire coal can be promoted to burn completely, and then improve boiler temperature and the thermal efficiency, reduce the discharge of pollutant.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；For a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
