Abstract
The utility model relates to a supply gas pressure balanced system of a gas boiler. The supply gas pressure balanced system comprises a main gas piping which winds around the gas boiler for a circle to form an annular pipeline, wherein the main gas piping is provided with a main gas inlet pipe which is communicated with a whole plant gas master pipe and is used for supplying gas for the main gas piping; gas inlet pipes of a rear wall burner of the gas boiler are connected in parallel to a rear wall gas supply branch pipe; two ends of the rear wall gas supply branch pipe are respectively communicated to the two sides of a ring of the main gas piping; the main gas piping is vertically divided into two parallel pipelines at one side winding the front wall of the gas boiler; one pipeline is respectively connected with each gas inlet pipe of a front wall upper layer burner; the other pipeline is respectively connected with each gas inlet pipe of a front wall lower burner. The annular pipeline is adopted for layout, the gas supply pressure fluctuation condition can be improved, the gas flow of each burner branch of the gas boiler is kept balanced, and the gas boiler can stably burn.
Description
Technical field
The utility model belongs to boiler technology field, relates to a kind of boiler supply gas pressure balance sysmte, especially a kind of gas fired-boiler supply gas pressure balance sysmte.
Background technology
In utilizing the device of blue charcoal emission power generation, blue charcoal tail gas, as fuel, need to be sent into gas fired-boiler by pipeline and burn, and the prerequisite of gas fired-boiler smooth combustion is that the gaseous-pressure before burner keeps constant.Before boiler-burner, whether gaseous-pressure is stablized, and operating mode and the safe operation of burning are had a significant impact.If the pressure before burner has increase and decrease, gas flow also can increase and decrease, and due to pressure transient, thereby causes combustion instability, even causes tempering and de-fire.
Steam line before many burner for gas boiler has dead end, is unfavorable for the equiblibrium mass distribution of each burner branch road air-flow, often causes air supply pressure fluctuation.
Utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of gas fired-boiler supply gas pressure balance sysmte is provided, this system adopts looped pipeline layout, can improve the situation of air supply pressure fluctuation, the air-flow of each burner branch road of gas fired-boiler is kept in balance, guarantee gas fired-boiler smooth combustion.
The purpose of this utility model solves by the following technical programs:
This gas fired-boiler supply gas pressure balance sysmte, comprises the total appendix that circularizes pipeline around gas fired-boiler one circle, on described total appendix, offers the female pipe of Yi Zhiyuquan factory combustion gas and is communicated with, and be the total inlet pipe of total appendix gas transmission; After each air inlet pipe parallel join to of the rear wall firing device of described gas fired-boiler piece, on wall gas manifold, the two ends of described rear wall gas manifold are communicated to respectively the annular both sides of total appendix; Described total appendix is being divided into two parallel pipelines up and down around gas fired-boiler front wall one side, and wherein one is connected with each air inlet pipe of front wall upper strata burner respectively, and another root is connected with each air inlet pipe of front wall lower floor burner respectively.
The position that above-mentioned total inlet pipe is connected on total appendix is: the middle part of the circulating line of wall one side after gas fired-boiler.
Further, at the two ends of described rear wall gas manifold, be provided with valve.
Above-mentioned total appendix at front wall, be divided into the two ends of two parallel pipelines be provided with valve.
The utlity model has following beneficial effect:
Gas fired-boiler supply gas pressure balance sysmte of the present utility model, adopt annular stringing mode, the annular configuration mode of this steam line is moved proof in engineering reality, supply gas pressure before every grate firing burner is constant, each branch road gas flow distributes comparatively even, the fluctuation of boiler gaseous-pressure is little, is conducive to Boiler Stable Combustion.
Accompanying drawing explanation
Fig. 1 is connection diagram of the present utility model.
Wherein: 1 is total appendix; 2 is gas fired-boiler; 3 is total inlet pipe; 4 is the female pipe of combustion gas; 5 is rear wall gas manifold.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1: the burner of gas fired-boiler 2 is generally distributed in the front-back wall of boiler.Native system adopts steam line annular configuration before burner.The following specifically describes (below the burner that is arranged in boiler front wall one side is called to " front wall firing device ", by being arranged in the burner of wall one side after boiler, is called " rear wall firing device "):
Gas fired-boiler supply gas pressure balance sysmte of the present utility model, comprises the total appendix 1 that circularizes pipeline around gas fired-boiler 2 one circles, on this total appendix 1, offers the female pipe 4 of Yi Zhiyuquan factory combustion gas and is communicated with, and be the total inlet pipe 3 of this total appendix 1 gas transmission.Each air inlet pipe of the rear wall firing device of gas fired-boiler 2 is parallel be communicated to one after on wall gas manifold 5, the two ends of this rear wall gas manifold 5 are communicated to respectively on the pipeline of annular both sides of total appendix 1; Total appendix 1 is being divided into two parallel pipelines up and down around gas fired-boiler 2 front wall one sides, and wherein one is connected with each air inlet pipe of the front wall firing device on upper strata respectively, and another root is connected with each air inlet pipe of the front wall firing device of lower floor respectively.
Further, the front-back wall of general high-temperature high-pressure fuel gas boiler totally 9 burners.Wherein front wall divides 2 layers, every layer of 3 burner; 1 layer, rear wall, every layer of 3 burner.The female Guan Yin of every boiler gas header pipe combustion gas from factory connects and at boiler front wall (2 layers), rear wall (1 layer), arranges circlewise respectively afterwards.
In sum, the utility model adopts steam line annular configuration before burner, because this arrangement does not have dead end, can at utmost guarantee that the gaseous-pressure before every grate firing burner keeps balance, the air-flow of each burner branch road of gas fired-boiler is kept in balance, guarantee gas fired-boiler smooth combustion.
