Abstract
The utility model discloses a double adjusting burner special for internal combustion type gas blast furnace which solves the problem that the prior blast furnace gas burner with jet device fails to adjust the intake quantity of the combustion-supporting air more effectively, further to meet the burning need of more blast furnaces. The utility model has the advantages of simple structure, convenient use, being capable of effectively improving the burning efficiency of the gas to save the energy and so on. The utility model comprises a nozzle arranged on one end of a coal gas pipeline, the jet device matched with the nozzle is arranged in the nozzle, the lower part of the nozzle is connected with a movable combustion tube through a connection device, and a gap is kept between the movable combustion tube and the nozzle.
Description
Technical field
The utility model relates to a kind of fuel burner nozzle that is applicable to all industrial gas, relates in particular to the two internal combustion type fuel burner nozzles of regulating of a kind of coal gas and combustion air.
Background technology
Along with the fast development of national economy, the energy consumption of iron and steel enterprises is also growing.And the international petroleum price is constantly soaring, to cost, the profit generation influence greatly of enterprise.Therefore, must seek a kind of good method, with the industrial gas that is produced in the industrial processes, make full use of as fuel gas such as blast furnace gas, coal gas of converter and coke-stove gas, go to substitute oil product, be a major issue of benefiting the nation and the people.
I am at 200610044238.x number " internal combustion blast furnace special gas nozzle of band mill dell body fluidic device " of first to file, No. 200610044236.0 " internal combustion blast furnace special gas nozzle of band cone fluidic device ", No. 200610044237.5 " internal combustion blast furnace special gas nozzle of band circular fluidic device ", three kinds of blast furnace gas special nozzle structures have been provided respectively, the burner of this form is not only applicable to the burning of blast furnace gas, also applicable to the burning of other industrial gas.It utilizes the fluidic device in the burner to realize automatic air distribution, has solved traditional burner because its unreasonable structure, must rely on combustion fan to come problem to the burner air distribution, thereby save combustion fan saving electric energy.The coal gas that has also solved traditional burner simultaneously mixes inhomogeneous with combustion air, influenced the problem of the chemical reaction of fuel and air.
But also there is a problem in above-mentioned three kinds of blast furnace gas special nozzles, the air capacity that promptly enters burner can't be carried out active adjustment, so just face a problem, the required combustion-supporting air quantity of coal gas of the different heat of promptly burning value has very big difference, therefore when coal gas and the variation of air proportioning than greatly the time, it often can not provide enough combustion airs timely, thereby influences the performance of its function.
Summary of the invention
The purpose of this utility model is exactly can not more effectively adjust the combustion air inlet for the blast furnace gas burner that solves present band fluidic device, can not satisfy the problem of more high combustion value coal gas firing needs, provide a kind of have simple in structure, easy to use, can effectively improve the efficiency of combustion of combustion gas, thus the coal gas and the two internal combustion type fuel burner nozzles of regulating of combustion air of advantages such as the saving energy.
For achieving the above object, the utility model adopts following technical scheme:
The two internal combustion type fuel burner nozzles of regulating of a kind of coal gas and combustion air, it has the nozzle that is installed in gas piping one end, the fluidic device that matches with it is installed in nozzle, and described nozzle bottom is connected with mobile combustion tube by jockey, leaves the slit between mobile combustion tube and nozzle.
Described jockey comprise be arranged on the nozzle bottom, around its peripheral baffle plate, baffle plate is provided with at least two combustion airs and adjusts handwheels, each combustion air is adjusted handwheel and is connected with separately connecting rod, the end of connecting rod then connects firmly with mobile combustion tube inwall.
Described fluidic device comprises a path transfer valve corresponding with nozzle diameter, and it is connected with the path transfer valve operating rod, and the top of path transfer valve operating rod is provided with the path transfer valve hand wheel.
Described path transfer valve is cone or prismoid or Rotary-table.
The utility model is on the basis of original burner, changed the regulative mode of its combustion air, change the mobile combustion tube of employing into by original passage, utilize the slit between combustion air adjustment handwheel adjustment combustion tube and nozzle then, reach the purpose of control combustion air inlet, so, burner of the present utility model can be adjusted the ratio of combustion air and combustion gas in wider scope, has satisfied the requirement of the various different heat value coal gas that burn.
The beneficial effects of the utility model are: simple in structure, easy to use, can not only be applicable to blast furnace gas, and also the burning applicable to present various industrial gas needs, and has the combustion rate height, and the carbon monoxide emission rate is low, compliance with environmental protection requirements.
Description of drawings
