Abstract
The utility model relates to a mixed burner which is capable of using two combustible gases, which belongs to the heat supply field. The burner is a pipe-group type casing structure, the pipe groups of the two gas fuels are evenly distributed in a same burner, the center position of the burner is distributed with a fixed lighting pipe to prevent the gas in a furnace hearth to leak, thereby leading the furnace hearth to explode, and playing the role of safety protection. The burner is equipped with two sets of impendent air inlet systems which are controlled through a valve and commonly use a same air duct, the two sets of gas fuel systems are opened at the same time, thereby being capable of achieving the mixing burning of the two gas fuels, and being capable of achieving the single burning of the fuel if switching. When mixed burning, the difficult problems that the gas calorific value of blast furnace coal is low, and the burning is not steady are solved. When single burning, the problems that the blast furnace coal and natural gas for burning are not produced when a blast furnace stops are solved, and a boiler is capable of being guaranteed to normally operate. The burner has simple structure, convenient installment and operation, and is capable of reducing the operation cost of the boiler.
Description
Technology neck city
The utility model belongs to the heat supply territory, specifically is a kind of combustion apparatus
Technical background
Use the boiler of gas with various fuel at present, because of the calorific value difference of fuel, fuel quantity has very big-difference, and burner can not be general, and promptly a kind of fuel is joined a kind of burner.Two kinds of fuel multifuel combustions just need be joined two kinds of burners, will drive two cover install combustion devices on the boiler and use the hole, though this kind form can realize multifuel combustion or single fire, but the quantity of burner doubles, quantity is many, cost is high and difficult layout, the burner that also easily will not move when in addition, two kinds of fuel switch burning burns out.
The utility model content
The purpose of this utility model is exactly for deficiency that overcomes prior art and defective, proposes a kind of mixing burner that utilizes two kinds of fuel gas, can satisfy the independent use of two kinds of gas with various fuel, uses when can satisfy two kinds of gas with various fuel again.
The purpose of this utility model is achieved through the following technical solutions: this utility model, comprise nest of tubes formula sleeve pipe, and air feed system is characterized in that: described nest of tubes formula sleeve pipe is made of blast furnace gas nest of tubes and natural gas nest of tubes; Blast furnace gas pipeline is connected by blast furnace gas gate valve and magnetic valve and blast furnace gas chamber, and the blast furnace gas chamber is connected with the blast furnace gas nest of tubes; Natural gas line is connected with natural air chamber by natural gas gate valve and magnetic valve, and natural air chamber is communicated with the natural gas tube faciation.Described nest of tubes formula sleeve pipe is made up of 33～41 root mass pipes, and the best is 34.Wherein 3～5 is the natural gas nest of tubes, and the best is 3.Wherein 30～36 is the blast furnace gas nest of tubes, and the best is 31.
In burner tube group center a Chang Mingguan is set, Chang Mingguan directly is connected with natural gas line by the Chang Mingguan valve.
This utility model promptly satisfies the independent use of two kinds of different fuels owing to adopted above technical scheme, uses when can satisfy two kinds of different fuels again, during multifuel combustion, has solved the difficult problem of the low combustion instability of blast furnace gas calorific value; During single fire, solved blast furnace stopping and do not produced blast furnace gas, natural gas fuel can guarantee that still boiler normally moves.This burner structure is simple, arrange, install, all more convenient and safety of operation, and in addition, other boiler that uses two kinds of fuel gas with needs is compared, and adopts this utility model can reduce the boiler operatiopn cost.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As depicted in figs. 1 and 2, burner adopts nest of tubes formula sleeve pipe, each burner is provided with 34 sleeve pipes and forms nest of tubes, and is made of 3 natural gas nest of tubes 10 and 31 blast furnace gas nest of tubes 9 respectively, is respectively arranged with gate valve 3,7 and magnetic valve 4,8 on natural gas line 1 and blast furnace gas pipeline 6.When utilizing the mixed combustion simultaneously of two kinds of fuel gas, the valve on natural gas line 1 and the blast furnace gas pipeline 6 is opened simultaneously, and can regulate the size of air inflow; In the time only need utilizing a certain fuel gas, can realize by opening, close the valve of adjusting on two kinds of fuel gas pipelines.The air feed of two kinds of different fuel gas is from same air feed system, and during burning blast furnace gas, wind can be simultaneously feeds from the fresh air inlet of natural gas nest of tubes 10; Wind also can feed from blast furnace gas nest of tubes 9 simultaneously when natural gas fuel.Because all nest of tubes all have air cooling when operation, so can not have the phenomenon that nest of tubes is burnt out.Use gas with various fuel institute required airflow difference, can control by regulating air channel adjustment doors 13.In burner tube group center a Chang Mingguan is set, Chang Mingguan directly is communicated with natural gas line 1 by valve 5.
