Abstract
The invention discloses a boiler-front combustible gas generator for a fluidized bed steam boiler. The provided equipment can make high-temperature low-pressure steam by itself and make chemical additives and coal react to form hydrogen and carbon monoxide. The boiler-front combustible gas generator for the fluidized bed steam boiler provided by the invention comprises a high temperature steam generator, a high temperature draught fan and a combustible gas generator. Hearth high temperature flue gas is introduced into the high temperature steam generator through the high temperature draught fan, and the high temperature flue gas can form high-temperature low-pressure steam after encountering steam, and the high-temperature low-pressure steam is conveyed to the combustible gas generator through a pipeline. The mixture of the coal and additives is sent to the combustible gas generator and generates hydrogen and carbon monoxide therein. And the produced hydrogen and carbon monoxide are sent into the hearth so as to provide combustible gas for combustion.
Description
Technical field
The present invention relates to a kind of equipment that changes fluidized bed steam Combustion Operation of Boilers, relate more specifically to a kind of stokehold inflammable gas generator for fluidized bed steam boiler, 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, inflammable gas quantity discharged is large, ash content carbon is high.This just caused under 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, 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 inflammable gas generator for fluidized bed steam boiler of the present invention 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 additive sprinkling equipment.
Illustrate further, according to the stokehold inflammable gas generator for fluidized bed steam boiler of the present invention, burner hearth high-temperature flue gas is introduced described high-temperature steam generator inside by described high temperature draught fan, and wherein said high-temperature flue gas runs into and forms high-temperature low-pressure steam after steam and described high-temperature low-pressure 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 fluidized-bed combustion boiler coal inlet, and wherein high-temperature low-pressure steam reacts in described inflammable gas generator with the mixture of coal additive and produces hydrogen and carbon monoxide; And the hydrogen producing and carbon monoxide be sent to burner hearth, to be provided for the inflammable gas of burning.

Stokehold inflammable gas generator for fluidized bed steam boiler of the present invention 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 low-pressure steam to the steam inlet 15 of inflammable gas generator 13.The external coal inlet 16 of sending into inflammable gas generator 13 after coal mixes with additive by transfer roller, then enters 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 gas such as hydrogen and carbon monoxide in inflammable gas generator 13.Hydrogen sprays to boiler with the inflammable gass such as carbon monoxide and unreacted large coal particles via the pipeline 18 being connected with the coal inlet of fluidized-bed combustion boiler.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 comprises barrel shell 1, 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.
Inflammable gas generator comprises barrel shell 13, cover 14, external inlet mouth 15, external coal inlet 16, gas-coal mixing tank 17 and external outlet 18.High-temperature steam is sent in inflammable gas generator 13 via the external inlet mouth 15 of inflammable gas generator 13.After mixing with additive, coal sends into the external coal inlet 16 of inflammable gas generator 13 by transfer roller.The coal and the additive that enter inflammable gas generator 13 mix through gas-coal mixing tank 17, and the inflammable gas such as hydrogen and carbon monoxide producing in inflammable gas generator 13, the inflammable gass such as hydrogen and carbon monoxide and unreacted large coal particles spray to boiler via the connecting tube 18 being connected with the coal inlet of fluidized-bed combustion boiler.The inflammable gass such as this hydrogen and carbon monoxide can participate in burning.
Stokehold inflammable gas generator for fluidized bed steam boiler of the present invention has following beneficial effect:
Boiler heating is fast, total input amount of coal is few, save the discharge 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 boiler coal inlet just can realize above-mentioned beneficial effect.
