Abstract

The utility model is composed of a primary wind swirl nozzle (1), a powder coal spray head (2), a gas spray head (3), a fuel oil spray head (4), a secondary wind swirl nozzle (5), a flame length adjustor (6), a cyclone combusting chamber (7), a tangent wind guiding inlet (8), a direct current wind guiding inlet (9), a central pipe (10) of the primary wind swirl nozzle, a measuring and peeping hole (11), etc. The utility model is characterized in that the incomplete combustion is carried out in the cyclone combusting chamber, then, the secondary wind is guided so that the complete combustion is achieved, and high temperature gas which is generated is used for supplying heat for an industrial furnace. The utility model has the advantages of high combustion efficiency, high heat utilization, fast ignition furnace open and adjustable flame length, and different kinds of fuel, such as powder coal, coal gas and fuel oil are used in the same combustor.

Description

Quick burning device
The utility model is a kind of burner.
At present, most of burner both domestic and external only can use list to plant fuel, uses the few of two kinds of fuel, and national conditions very difficult and that China's fuel type is changeable adapt.Simultaneously, nearly all burner is at all more time-consuming material that takes of when igniting, and pollute and waste serious, especially during the black furnace igniting, situation is more difficult and serious.General burner all is in fuel sprays into stove the time, ability is mixed with combustion air and is burnt, and be mostly that in the flame flow thigh air outside, fuel is interior, thereby cause the burner strong oxidizing atmosphere, even under a large amount of air excess situations, it is also incomplete to burn, cause the workpiece oxidization burning loss to increase and the efficiency of combustion reduction.
The purpose of this utility model is to invent a kind of burner, and it can use pluralities of fuel, and igniting and blow-on are quick, realize completing combustion under the less situation of air excess amount, improves efficiency of combustion, and reduces oxidization burning loss.
The utility model is a kind of multipurpose efficient conflagration device, it is by a wind cyclone (1), fine coal shower nozzle (2), gas-jet (3), fuel oil shower nozzle (4), secondary wind cyclone (5), length of flame adjuster (6), cyclone combustion chamber (7), tangent line wind intake (8), direct current wind intake (9), a wind cyclone central tube (10) is measured peep-hole formations such as (11).Its characteristics are that burner has cyclone combustion chamber, and the front, combustion chamber is the wind cyclone once, and there is secondary wind cyclone the back, fuel is at the indoor imperfect combustion that at first carries out of cyclone firing, feed secondary wind then, reach completing combustion, the high-temperature gas of generation is used as the industrial furnace heat supply.Fine coal, coal gas, three shower nozzles of fuel oil are contained in a burner simultaneously.
The utility model utilizes a wind cyclone (1), makes fine coal, coal gas and fuel oil realize high-intensity combustion in cyclone combustion chamber (7), and its temperature is controlled at 800-1200 ℃, and the imperfect combustion degree is 0.3-0.6.Because a wind cyclone makes air have bigger swirl strength (0.6-1.8), add higher air flow inlet speed (15-30 meter per second) and higher preheat temperature (150-300 ℃), make more complete that combustion reaction carries out.
When using fine coal, fine coal enters cyclone by fine coal shower nozzle (2) with a wind, and when using coal gas and fuel oil, then by gas-jet (3) and fuel oil shower nozzle (4), enter cyclone by a wind cyclone central tube (10), in the indoor burning of catching fire of cyclone firing, three kinds of fuel can use simultaneously, also can use separately then.
Cyclone combustion chamber is the fire-resistant stamp mass that is lined with the combination of one deck phosphoric acid in, and thickness is the 60-100 millimeter, and its volume intensity is (2~8) * 4.18 * 10 6Kilojoule/rice 3The time, its L/D ratio is 2-4 times, outer wall has a plurality of secondary air channels.
The secondary wind action is to make fuel completing combustion, introduces at 1/4-1/2 place of cyclone combustion chamber length, and its amount is the 70-40% of completing combustion required air quantity, and air themperature can be preheated to 300-500 ℃.
At rear portion, combustion chamber Cheng Shuan tangent line wind intake and direct current wind intake are housed alternately, secondary wind enters the combustion chamber by secondary cyclone (5), its swirl strength is 0.2-0.5, the inlet flow velocity is the 8-20 meter per second, by length of flame adjuster (6), earlier from direct current wind intake (9), enter the single flow air channel, enter cyclone combustion chamber then, obtain long combustion flame, also can enter cyclone combustion chamber, obtain short combustion flame, to satisfy the different heating processes and the requirement of furnace by tangent-type wind intake (8).Corresponding have secondary air channel at outer wall of combustion chamber.
Peep-hole and fire hole are equipped with in the burner termination, and the measurement peep-hole is furnished with quartz glass and the external world is separated by, and its subtended angle is greater than 40 °, and fire hole communicates with a wind cyclone central tube, and parallel mutually in the fuel oil shower nozzle.Ignition operation can be lighted a fire with electric igniter and gas igniter, also can light a fire with oily cotton yarn, its fire location must be in the recirculating zone, the terminal the place ahead of cyclone central tube, swirl flow combustion is indoor catch fire after, the high-temperature gas of ejection, can be to the stove heat supply, thereby the duration of ignition is very short, the blow-on time also shortens immediately.It is very fast that stove heats up, and makes that ignition process saves time, material-saving, and the pollution (as the over-emitting black exhaust phenomenon) that ignition process causes then can be exempted.
Owing to the temperature that cyclone firing is indoor is higher, make combustion process stable.Also can obtain stable burning during the thermic load change, enlarge and regulate ratio, can also adapt to different furnace temperature requirements simultaneously, be applicable to high temperature, middle temperature even low temperature oven needs.Because one time wind can use high-temperature preheated air combustion-supporting, secondary wind also can use higher wind-warm syndrome, thereby energy-saving effect is obvious, has improved the thermal efficiency of stove.
The utility model has the advantages that: same burner can use fine coal, coal gas, fuel oil pluralities of fuel, have high burning efficiency and high heat utilization rate, the length of flame is adjustable, the igniting blow-on is quick, and it is combustion-supporting to use high-temperature preheated air, capable of saving fuel, this burner is applicable to various high temperature, middle gentle low-temperature industrial stove.
Fig. 1 is a kind of structure chart of the present utility model, and Fig. 2 is Figure 1A-A profile.
