Abstract
The present invention discloses the Combustion System technique of a kind of coal-burning boiler, comprises the following steps, defeated device for coal send into the raw coal of coal bunker, directly falls in the fire grate moved forward and enters the combustor of burner hearth；The air burnt in a combustion chamber is supplied by the blower fan under fire grate, high-temperature flue gas produced by fuel combustion transmits heat to the water-cooling wall of combustor surrounding in the way of radiation heat release, then enter convection pass through slag screen, convection pass is disposed with convection bank and constitutes heating surface；Convection bank is the cluster tube bank connected together with upper lower drum, and the water in pipe absorbs the heat in flue and heats up；A part heated high-temperature water in upper drum enters water supply line；After flue gas washes away convection bank and lower drum releasing heat in flue, enter back-end ductwork, then enter air through air-introduced machine and chimney.There is reasonable in design, the feature being easily controlled of burning.
Description
Technical field
The invention belongs to boiler plant technical field, be specifically related to the Combustion System technique of a kind of coal-burning boiler.
Background technology
Developing rapidly along with socioeconomic, the continuous expansion of urban construction scale, automatic control system is applied the most gradually
To steam generator system, finish conventional steam generator system all by the backward situation of artificial or simple electrical control, alleviate monitoring
The labor intensity of personnel, it is to avoid human negligence and the accident that causes occurs.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that the Combustion System technique of a kind of coal-burning boiler, there is design
Rationally, the feature that burning is easily controlled, heats is good.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The Combustion System technique of a kind of coal-burning boiler, comprises the following steps, defeated device for coal send into the raw coal of coal bunker, directly fall in
The fire grate moved forward enters the combustor of burner hearth；The air burnt in a combustion chamber is supplied by the blower fan under fire grate, and fuel fires
Burn produced high-temperature flue gas and transmit heat to the water-cooling wall of combustor surrounding in the way of radiation heat release, then enter through slag screen
Enter convection pass, convection pass is disposed with convection bank and constitutes heating surface；Convection bank connects together with upper lower drum
Cluster is restrained, and the water in pipe absorbs the heat in flue and heats up；A part heated high-temperature water in upper drum enters and supplies
Waterpipe；After flue gas washes away convection bank and lower drum releasing heat in flue, enter back-end ductwork, then through air-introduced machine
Air is entered with chimney.
Further, described convection pass is divided into by cigarette wall.
Further, the motor that described fire grate connects is started by Frequency Converter Control and stops.
Compared with prior art, the present invention has a following beneficial effect:
The present invention is reasonable in design, easy to use, uses the supply of Frequency Converter Control fire coal consumption, it is achieved that boiler combustion is energy-conservation
Optimal control, control level and hardware reliability are greatly improved.
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Embodiment, the Combustion System technique of a kind of coal-burning boiler, comprise the following steps, defeated device for coal send into the former of coal bunker
Coal, directly falls in the fire grate moved forward and enters the combustor of burner hearth；The motor that described fire grate connects is started by Frequency Converter Control
And stopping.The air burnt in a combustion chamber is supplied by the blower fan under fire grate, and produced by fuel combustion, high-temperature flue gas is with radiation
The mode of heat release transmits heat to the water-cooling wall of combustor surrounding, then enters convection pass, cloth in convection pass through slag screen
It is equipped with convection bank and constitutes heating surface.Described convection pass is divided into by cigarette wall.Convection bank is to be connected in one with upper lower drum
The cluster tube bank risen, the water in pipe absorbs the heat in flue and heats up.A part heated high-temperature water in upper drum enters
Enter water supply line.After flue gas washes away convection bank and lower drum releasing heat in flue, enter back-end ductwork, then through drawing
Blower fan and chimney enter air.
The foregoing is only explanation embodiments of the present invention, be not limited to the present invention, for the technology of this area
For personnel, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection scope of the present invention.
Claims (3)
