Abstract
The invention provides an arrangement structure of a heating surface of a coke oven gas boiler in the coal chemical industry. Coke oven gas is used as a fuel of the boiler, so that the boiler operates efficiently, the industrial structure is reasonable and the structure is very economical. The structure comprises a hearth and is characterized in that a high temperature superheater and a low temperature superheater are sequentially arranged in a horizontal flue part at the outlet of the hearth, a coal saver and an air preheater are sequentially arranged in a vertical flue at the tail part from top to bottom, and a combustion chamber is arranged on the lower part of the hearth. Three cyclone gas combustors are arranged on two side walls of the combustion chamber in a shape like a Chinese character 'pin'.
Description
Technical field
The present invention relates to the technical field of Coal Chemical Industry Coke-oven Gas Boiler, be specially the arrangement of Coal Chemical Industry Coke-oven Gas Boiler heating surface.
Background technology
China is the maximum coke production state in the whole world, there were 997 coal chemical enterprises in China in 2007, and coke output reaches 33,553 ten thousand tons, accounts for 60% of world's coke output, the coke-oven coal tolerance that produces is huge, and the utilization of coke-stove gas mainly is catalyzing part oxidation method synthesizing methanol and generating.The coke-stove gas calorific value of most domestic is at 18000～19300kJ/m
3(4302～4613kcal/m
3) about, H
2Content up to 60%, CH
4Reach 25%.But some Coal Chemical Industry industry is produced the coke-stove gas calorific value that produces in the chain only at～7900kJ/m3(～1900kcal/m
3) about, H
2Content only～28.4%, CH
4Content only～7.2%, it is underproof being used as synthesizing methanol, if but these coal gas are used as generating and heat supply, for the Chemical Manufacture of production in the chain, the industrial structure is still very rational, also is very economical.
Summary of the invention
For the problems referred to above, the invention provides the arrangement of Coal Chemical Industry Coke-oven Gas Boiler heating surface, it guarantees the high efficiency boiler operation with the fuel of coke-stove gas as boiler, the industrial structure is reasonable, and very economical.
The arrangement of Coal Chemical Industry Coke-oven Gas Boiler heating surface, its technical scheme is such: it comprises burner hearth, it is characterized in that: the horizontal flue part in the exit of described burner hearth is furnished with high temperature superheater, low temperature superheater in turn, tail vertical well gas flue is furnished with economizer, air preheater from top to bottom in turn, the bottom of described burner hearth is the combustion chamber, and three eddy flow gas burners are down on the Chinese character pin-shaped both walls that is arranged in described combustion chamber.
After adopting structure of the present invention, in order to ensure steam parameter, superheater system of the present invention only is comprised of high temperature superheater, low temperature superheater two parts, avoided the high-temperature region in burner hearth to arrange screen formula radiation superheater, so that a large amount of caloric requirements absorbs by back-end surfaces, can effectively guarantee steam parameter, owing to save primary superheater, not only economical, and favourable to the Safety of Superheater of boiler; The burner of Chinese character pin-shaped layout of falling has preferably steady combustion effect for low-heat value gas, and it guarantees the high efficiency boiler operation with the fuel of coke-stove gas as boiler, and the industrial structure is reasonable, and very economical.
Description of drawings
Fig. 1 is front view structural representation of the present invention.
The specific embodiment
See Fig. 1, it comprises burner hearth 1, the horizontal flue part in the exit of burner hearth 1 is furnished with high temperature superheater 2, low temperature superheater 3 in turn, tail vertical well gas flue is furnished with economizer 4, air preheater 5 from top to bottom in turn, the bottom of burner hearth 1 is that 7, three the eddy flow gas burners 6 in combustion chamber are down on the Chinese character pin-shaped both walls that is arranged in combustion chamber 7.
