Description
Technical field
The present invention relates to a kind of industrial gas burner igniter and center smooth burning method thereof, this ignition device success rate is high, flame stabilization, NOx emission are low, belongs to 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 heating such as Beijing, Xinjiang, Tianjin changes 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 have higher requirement to the performance of burner.Gas burner is just towards high-power, the development of energy-conservation stabilising direction.
Known high power gas burner, or low heat value gas combustion burner adopts the supply mode of center low speed combustion air, burning torch is also being positioned at the igniting of low speed combustion air region, but most burner is when dispensing fuel, center does not have fuel supply, and burning torch can only be utilized directly to light peripheral fuel.The patent No. of Shanghai Nuote Feibo Combustion Equipment Co., Ltd is (ZL200710045046.5), name is called that < mono-kind guarantees the method for industrial burner stable burning and the patent of invention of device > thereof, set forth the method for a small amount of combustion gas of a kind of low speed combustion air of the heart in the burner region dispensing, to strengthen igniting, smooth combustion.The method structure is simple, and practicality improves greatly.But this technology, for high-power burner and the burner requiring low NOx drainage, application has certain limitation, often there is the defect that ignition flame stability is inadequate.
Summary of the invention
Object of the present invention: in order to improve the defect of high-power industrial gas burner ignitor flame instability further, and reduce NOx emission, 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 pipe and central tube outer tube in central tube, in described central tube, pipe is placed in described central tube outer tube, and coaxial-symmetrical is arranged, the combustion gas admission passage of ring-type fuel gas ejecting device centered by between described central tube outer tube is managed in described central tube, the combustion gas admission passage upper end of described central loop fuel gas ejecting device is blocked up by ring-type blast tube cap seal, the inner peripheral of described ring-type blast tube lid is fixedly connected with pipe upper end in described central tube, 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 inner outward-dipping central loop gas nozzle upwards.
Angularly α is from inner upwards outward-dipping in the axis of described central loop gas nozzle fuel gas injection direction and described central tube, and described α is 20 ° ~ 90 °.
The invention has the beneficial effects as follows: the dispensing mode improving fuel, low speed combustion air region in central tube, the combustion gas of a small amount of annular membrane shape is ejected by central loop fuel gas ejecting device dispensing, substantially territory, whole low velocity annular region can be covered, burning torch is utilized 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, decreases the generation of NOx.Thus set up stable flame of centre, then by Whirl deposite tank, 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 stabilize the main flame of high-power burner.
