Abstract
The utility model discloses a stokehole combustible gas generator for a chain grate stoker steam boiler. The stokehole combustible gas generator can heat high-pressure steam into high-temperature steam and generate hydrogen, carbon monoxide and other combustible gases through reaction between additives and pulverized coal. The stokehole combustible gas generator for the chain grate stoker steam boiler comprises a conveyor, a pressurization pulverized coal machine and a combustible gas generator body. The high-pressure steam is sent into a steam heating diffuser of the combustible gas generator body and the high temperature of a furnace is made to be radiated on the steam heating diffuser; the temperature of the high-pressure steam is raised inside the steam heating diffuser, so that the high-pressure steam becomes the high-temperature steam, and the high-temperature steam enters the combustible gas generator body and is sprayed towards the pulverized coal; a mixture of the pulverized coal and the additives is sent into the pressurization pulverized coal machine, levigated and mixed, and then sent into the combustible gas generator body through a pipeline; the combustible gases are generated inside the combustible gas generator body, the combustible gases are sprayed towards the furnace, and therefore gas fuel is provided conveniently.
Description
Technical field
The present invention relates to a kind of equipment that changes the combustion conditions of chain fire-gate steam boiler, relate more specifically to a kind of stokehold for traveling-grate stoker steam boiler inflammable gas generator, this equipment not only can be saved coal and can reduce carbon dioxide and other noxious gas emissions.
Background technology
Present stage, the heating of China and Industrial Boiler adopt traveling-grate stoker as combustion apparatus basically.Chain fire-gate defect is obvious, and for example chemical combustion is insufficient, the fuel gas discharge capacity large, the deslagging phosphorus content is large and excess air is large.This has just caused under the unit heating load and can consume more coal and discharge more sulfur dioxide and other pernicious gases.In addition, the method that adds Coal powder spray can not fully be burnt because the fiery chamber of chain grate boiler is little, so the thermal efficiency of boiler is low.
Summary of the invention
For the defect that the chemical combustion that overcomes chain grate boiler is insufficient, the fuel gas discharge capacity large, the deslagging phosphorus content is large, excess air is large and boiler thermal output is low, the invention provides a kind of make high-temperature steam by oneself and make chemical addition agent and coal reaction to form the equipment of the fuel gas such as hydrogen and carbon monoxide, hydrogen and carbon monoxide can participate in boiler combustion, thereby address the above problem.
Mainly comprise conveyer, pressurization Coal-disintegrating machine, inflammable gas generator and connecting pipe according to the stokehold for the traveling-grate stoker steam boiler of the present invention inflammable gas generator.
Illustrate further, according to the stokehold for the traveling-grate stoker steam boiler of the present invention inflammable gas generator, the steam that high steam is admitted to described inflammable gas generator is heated in disperser, and makes the hyperthermia radiation of burner hearth on described steam is heated disperser by external outlet in inflammable gas generator; Make the temperature of high steam increase to high-temperature steam in described steam is heated disperser, described high-temperature steam enters in described inflammable gas generator via steam jet and sprays to coal dust in described inflammable gas generator; The mixture of coal and additive is delivered in described pressurization Coal-disintegrating machine by described conveyer and, by levigate and mix, by coal and additive levigate and that mix, through piping, is sent to described inflammable gas generator; And in described inflammable gas generator by the mixed flow generation fuel gas of joining, described fuel gas sprays to burner hearth by the external outlet that is connected with the ignition of the boiler door, so that the gaseous fuel that is provided for burning.

The specific embodiment
Below, the present invention is further described in connection with accompanying drawing.
Fig. 1 is the overall schematic according to the stokehold for the traveling-grate stoker steam boiler of the present invention inflammable gas generator.
Stokehold for the traveling-grate stoker steam boiler of the present invention inflammable gas generator mainly comprises inflammable gas generator 1, pressurization coal pulverizer 12 and coal conveying equipment 13 three parts.High steam enters steam through steam inlet 9 and heats in disperser 10.In inflammable gas generator 1 by external outlet 5 with the hyperthermia radiation of burner hearth on steam is heated disperser.The high steams that steam is heated in disperser 10 are heated to high temperature steam.High-temperature steam enters in inflammable gas generator 1 via steam jet 11 and sprays to the interior coal dust of inflammable gas generator 1.The mixture of coal and additive is sent to pressurization coal pulverizer 12 by conveyer 13, and by levigate and mix after, in pipeline 14 is delivered to inflammable gas generator 1.At the interior fuel gas that produces after mixed flow is joined of inflammable gas generator 1.The fuel gas that produces sprays to boiler by the external outlet 5 that is connected with the ignition of the boiler door.Fuel gas can participate in burning.
Fig. 2 A is the front schematic view of inflammable gas generator; And Fig. 2 B is the side schematic view of inflammable gas generator.
Stokehold for the fluid bed heat homogeneous solution-type reactor of the present invention inflammable gas generator has following beneficial effect:
Boiler heating is fast, total input amount of coal is few, save the discharging of the pernicious gases such as coal and minimizing carbon dioxide, thereby has improved the thermal efficiency of boiler.Control panel is owing to having adopted converter technique, thus stable, regulate freely, simple to operate.In addition,, according to technical scheme of the present invention, do not need to transform boiler, only borrow the boiler coal feed point just can realize above-mentioned beneficial effect.
