Description
Technical field
The utility model relates to the technical field of boiler, is specially a kind of high combustion value coal gas boiler.
Background technology
Because chemical industry is produced the particularity of chain, has produced the very high gas of calorific value in process of production, the low heat valve of gas reaches 21524～27363.98 kcal/Nm3, is more than 2 times of heating value of natural gas.
Existing boiler is not suitable for the burning of these high heat value gas, therefore can only emptying.Be the energy waste of avoiding these high heat value gas emptyings to cause, if these coal gas can be used as generating and heat supply, for the Chemical Manufacture usefulness of producing in the chain, the industrial structure of chemical industry will be more reasonable also more economical so.
Summary of the invention
At the problems referred to above, the utility model provides a kind of high combustion value coal gas boiler, and its fuel is the high heating value combustion gas, and the steam that boiler produces can be used for generating, steam supply and heat supply, makes the energy rationally be utilized.
A kind of high combustion value coal gas boiler, its technical scheme is such: it comprises burner hearth, tail vertical well, water-cooling wall, superheater, economizer, air preheater, horizontal flue, the top of described burner hearth is communicated with the top of described tail vertical well by described horizontal flue, it is characterized in that: be described water-cooling wall around the described burner hearth, the side wall of described tail vertical well is provided with steam, the side wall of described horizontal flue is provided with bag wall superheater, described water-cooling wall, steam, bag wall superheater is membrane wall structure, at least two burners are arranged side by side in the front wall of described burner hearth, extend to the back wall after 5 ° of the preceding water-cooling wall lower tilt of described front wall inboard, form the furnace bottom water-cooling wall, the top of described furnace bottom water-cooling wall is provided with fire brick layer, described superheater comprises high temperature superheater, low temperature superheater, steam, bag wall superheater, described high temperature superheater, low temperature superheater is arranged in the described horizontal flue in turn, described high temperature superheater, the inner flow passage of low temperature superheater is communicated with direct-contact desuperheater respectively, described economizer, air preheater is single-stage and arranges, be arranged in the tail vertical well in turn.
It is further characterized in that:
Described high temperature superheater is positioned at the place ahead of described horizontal channel, and described low temperature superheater is positioned at the rear of described horizontal flue;
Described economizer has two groups, and two groups of described economizers are arranged in separately respectively in the described tail vertical well in turn, and described air preheater has two groups, and two groups of described air preheaters are arranged in the described tail vertical well separately respectively in turn;
Described economizer is the spiral fin coil economizer;
Described air preheater is horizontal arrangement form;
Described burner is the gas burner of cyclone structure;
Connection place of described back wall and described horizontal flue is provided with protruding rear arch to described burner hearth.
After adopting structure of the present utility model, because boiler design is single drum Natural Circulation chamber burner, and around the burner hearth, the tail vertical well side wall, the horizontal flue side wall is membrane wall structure, extend to the back wall after 5 ° of the preceding water-cooling wall lower tilt of front wall inboard, form the furnace bottom water-cooling wall, the top of furnace bottom water-cooling wall is provided with fire brick layer, its steam heat that makes boiler produce can directly be absorbed by the membrane type wall construction to be taken away, the inwall of guaranteeing boiler is not destroyed by high temperature, and because high temperature superheater, low temperature superheater is arranged in the described horizontal flue in turn, described high temperature superheater, the inner flow passage of low temperature superheater is communicated with direct-contact desuperheater respectively, described economizer, air preheater is single-stage and arranges, be arranged in the tail vertical well in turn, its heat that makes the gas-fired of high heating value produce can access sufficient conversion, and because at least two burners are arranged side by side in the front wall of burner hearth, make the sufficient combustion of burner hearth inside, it has been guaranteed when fuel is the high heating value combustion gas, the steam that boiler produces can be used for generating, steam supply and heat supply make the energy rationally be utilized.
