Abstract
The utility model discloses a furnace front combustible gas generator for a fluidized bed steam boiler. The device can produce high temperature vapor, and enable the chemical addition agent to be reacted with the coal to form hydrogen and carbon monoxide. The furnace front combustible gas generator for the fluidized bed steam boiler comprises a high temperature steam generator, a high temperature induced-draft fan and a combustible gas generator, wherein high temperature smoke in a furnace chamber enters into the inner part of the high temperature steam generator through the high temperature induced-draft fan; high temperature smoke meets the vapor to form high temperature vapor, and the high temperature vapor is delivered into the combustible gas generator through a pipeline; the mixture of the coal and the additive is sent to the combustible gas generator, and hydrogen and carbon monoxide are generated from the combustible gas generator and are blown into the furnace chamber; so that the combustible gas for combustion is provided.
Description
Technical field
The present invention relates to a kind of equipment that changes the fluidized bed steam Combustion Operation of Boilers, relate more specifically to a kind of stokehold for fluidized bed steam boiler inflammable gas generator, this equipment not only can be saved coal and can reduce carbonic acid gas and other noxious gas emissions.
Background technology
The open defect of existing fluidized bed steam boiler is that chemical combustion is insufficient, the inflammable gas quantity discharged is large, ash content carbon is high.This just caused under the unit heat supplied can consume more coal many, discharge more carbonic acid gas and other obnoxious flavour, thereby boiler efficiency is low.
Summary of the invention
In order to overcome the defect that the chemical combustion of fluidized bed steam boiler is insufficient, the inflammable gas quantity discharged is large, ash content carbon is high and boiler thermal output is low, the invention provides a kind of make high-temperature steam by oneself and make chemical additive and coal reaction to form the equipment of hydrogen and carbon monoxide, hydrogen and carbon monoxide can participate in boiler combustion, thereby address the above problem.
Stokehold for the fluidized bed steam boiler of the present invention inflammable gas generator comprises high-temperature steam generator, high temperature draught fan, inflammable gas generator and connecting tube.In addition, the temperature of material and water, humidity, online discharge monitoring can be connected with PLC, can carry out in this case Fuzzy Processing and can match with the additive sprinkling equipment.
Illustrate further, according to the stokehold for the fluidized bed steam boiler of the present invention inflammable gas generator, it is inner that the burner hearth high-temperature flue gas is introduced described high-temperature steam generator by described high temperature draught fan, and wherein said high-temperature flue gas runs into after steam and forms high-temperature steam and described high-temperature steam is transported to described inflammable gas generator via pipeline; The mixture of coal and additive is delivered to described inflammable gas generator via pipeline, the outlet of wherein said inflammable gas generator is connected with the fluidized-bed combustion boiler coal inlet, and wherein coal and additive react and produce hydrogen and carbon monoxide in described inflammable gas generator; And the hydrogen that produces and carbon monoxide be sent to burner hearth, so that the inflammable gas that is provided for burning.

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 fluidized bed steam boiler of the present invention inflammable gas generator.
Stokehold for the fluidized bed steam boiler of the present invention inflammable gas generator mainly comprises high-temperature steam generator 1, high temperature draught fan 12 and inflammable gas generator 13 three parts.Due to the magnetism of high temperature draught fan 12, high-temperature flue gas is introduced to the external import 4 of high-temperature steam generator 1 from upper boiler, then enter in high-temperature steam generator 1.Steam is sent into steam decollator 7 and sprays to high-temperature flue gas via steam inlet 6, thereby produces high-temperature steam.Then high-temperature steam is discharged via external outlet 5.Connecting tube 19, high temperature draught fan 12 and connecting tube 20 are sent high-temperature steam to the steam inlet 15 of inflammable gas generator 13.Send into the external coal inlet 16 of inflammable gas generator 13 after coal mixes with additive by transfer roller, then enter inflammable gas generator 13.The coal and the additive that enter inflammable gas generator 13 mix through gas-coal mixing tank 17, and produce the inflammable gass such as hydrogen and carbon monoxide in inflammable gas generator 13.Hydrogen is connected inflammable gas and unreacted large coal particles to spray to boiler via the pipeline 18 that is connected with the coal inlet of fluidized-bed combustion boiler with carbon monoxide.The inflammable gass such as this hydrogen and carbon monoxide can participate in burning.
Fig. 2 A and Fig. 2 B are the views that high-temperature steam generator 1 is shown.
High-temperature steam generator 1 comprises barrel shell, cover 2, cover 3, external import 4, pick out 5 mouthfuls, steam inlet 6, steam decollator 7, temp probe 8, moisture probe 9, water port 10 and steam nozzle 11.Due to the magnetism of high temperature draught fan, high-temperature flue gas enters in high-temperature steam generator 1 from the external import 4 of the high-temperature steam generator 1 of connection upper boiler.Steam enters steam decollator 7 and sprays to uniformly high-temperature flue gas from steam inlet 6, thereby produces high-temperature steam.
Fig. 3 A and Fig. 3 B are the views that inflammable gas generator 13 is shown.
Stokehold for the fluidized bed steam boiler 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 obnoxious flavoures such as coal and minimizing carbonic acid gas, thereby has improved the thermo-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 inlet just can realize above-mentioned beneficial effect.
