Description
Technical field
The utility model relates to boiler combustion device, particularly relates to a kind of boiler natural gas fired burner with layering control valve.
Background technology
Chinese Patent Application No. 201220369585.0 discloses a kind of pulverized coal flame natural gas fired system, this system is that multilayer is arranged, every layer comprise again layering main pipeline and with the lateral formed by layering main pipeline bifurcated, every road lateral connects gas gun, enter combustion gas rob interior combustion gas to regulate, general Hui Mei road lateral installs gas pressure regulating valve respectively, but due to pressure regulator valve being installed by Jin Mei road lateral, just needs to overlap actuator more.Because modern boiler generally adopts decentralised control (DCS) system, just need to take multiple control channel, operating personnel are needed to adjust control respectively to it one by one, not only equipment cost is high, and the monitoring workload of personnel increases, the pressure of every gas gun can not ensure unanimously, to affect exerting oneself and ignition process of gas gun completely.
Utility model content
For the deficiency in background technology, the purpose of this utility model is to provide a kind of boiler natural gas fired burner with layering control valve, can reduce equipment cost, system is simplified.
The technical solution of the utility model is achieved in that
A kind of boiler natural gas fired burner with layering control valve, its layering main pipeline mainly comprising transport gas and the lateral be connected with described layering main pipeline, be arranged at many gas guns on boiler, each gas gun is connected with lateral by flexible hose, wherein control valve is installed by each layering main pipeline.
The utility model compared with prior art, there is following advantage: the utility model by installing pressure regulator valve on the main pipeline of every layer, gas pressure regulation is regulated according to layer, instead of each gas gun regulates separately, the needs of natural gas fired can not only be met, and saving equipment cost, reduce the workload of controllers.
As preferably, also comprise combustion gas mother pipe, described combustion gas mother pipe is provided with total valve successively according to combustion gas input direction; Total main-piping pressure transmitter; Pressure switch group; Described pressure switch group can implement overvoltage, under-voltage protection for whole system.
As preferably, described pressure switch group connects A layer main line, B layer main line and C layer main line successively.
As preferably, described layering main pipeline is provided with pressure regulator valve successively according to combustion gas input direction, and zonal pressure transmitter, described zonal pressure transmitter connects four road laterals respectively.
As preferably, described every road lateral is provided with manual ball valve, electric quick-closing valve, temper device, arm pressure transmitter and Pressure gauge successively.
