Technical field
The utility model relates to a kind of industrial gas burner igniter and center smooth burning method thereof, and this ignition device success rate is high, flame stabilization, NOx discharge is low, belongs to the industrial gas burner technical field.
Background technology
At present, along with the extensive use of domestic combustion gas, the perfect of circuit of transferring natural gas from the west to the east, the coal of the ground such as Beijing, Xinjiang, Tianjin heating changes the gas engineering and just deeply carries out.In addition, various casing-head gas, industrial waste gas also collect and are used as industrial combustion gas, so just the performance of burner are had higher requirement.Gas burner is just towards high-power, the development of energy-conservation stabilising direction.
Known high power gas burner, perhaps low heat value gas combustion burner adopts the supply mode of center low speed combustion air, burning torch also is being positioned at the igniting of low speed combustion air zone, but most burners are when dispensing fuel, center does not have fuel to be supplied with, and can only utilize burning torch directly to light peripheral fuel.The patent No. of Shanghai Nuote Feibo Combustion Equipment Co., Ltd is (ZL200710045046.5), name is called the utility model patent of<a kind of method and device thereof of guaranteeing industrial burner stable burning>, set forth a kind of method in a small amount of combustion gas of burner center low speed combustion air zone dispensing, with strengthening igniting, smooth combustion.The method is simple in structure, and practicality improves greatly.But this technology, for high-power burner and the burner that requires low NOx drainage, has certain limitation in application, often have the defect that ignition flame stability is inadequate.
Summary of the invention
The purpose of this utility model: in order further to improve the unsettled defect of high-power industrial gas burner ignitor flame, and reduce the NOx discharge, a kind of industrial gas burner ignition smooth combustion apparatus is provided.
For achieving the above object, the technical scheme adopted is: a kind of industrial gas burner ignition smooth combustion apparatus, comprise central tube, central tube, cyclone, burning torch and main gas gun, it is characterized in that: described central tube comprises central tube inner tube and central tube outer tube, described central tube inner tube is placed in described central tube outer tube, and coaxial-symmetrical setting, the combustion gas admission passage of ring-type fuel gas ejecting device centered by between described central tube inner tube and described central tube outer tube, the combustion gas admission passage upper end of described center ring-type fuel gas ejecting device is stifled by ring-type blast tube cap seal, the inner peripheral of described ring-type blast tube lid is fixedly connected with described central tube inner tube upper end, the outer periphery angled end-face of described ring-type blast tube lid and the angled end-face adjoiner of described central tube outer tube upper end, be equipped with from the outward-dipping center ring-type gas nozzle made progress.
The axis of described center ring-type gas nozzle fuel gas injection direction and described central tube be angle [alpha] from outward-dipping upwards, described α is 20 °～90 °.
The beneficial effects of the utility model are: the dispensing mode of having improved fuel, low speed combustion air zone in central tube, by center ring-type fuel gas ejecting device dispensing and eject the combustion gas of a small amount of annular membrane shape, can substantially cover whole low speed central area, utilize burning torch first to light this part annular membrane shape combustion gas, with the full and uniform mixed combustion of low speed central tube air, the flue gas of generation can dilute the root oxygen amount of main flame, has reduced the generation of NOx.Thereby set up stable flame of centre, then by eddy flow wind, flame of centre is taken to peripheral fuel region, light peripheral fuel.Set up the membranaceous flame of stable annular in the central area of burner, and then stablized the main flame of high-power burner.
