Embodiment Construction
[0028] Such as figure 1 , 2 . 3 shows the first oil-oxygen combustion non-premixed start-up burner of the present invention. The head of the burner is provided with a head injection part, and the end surface of the head injection part is provided with a flame nozzle. The oxygen channel and the oil channel are set, and the flame nozzle includes an oxygen nozzle and an oil nozzle, and the number of the oil nozzle is four; the number of the oxygen nozzle is eight; the oxygen nozzle is connected with the oxygen channel, and the oil nozzle is connected with the oil channel. An atomizer is arranged between the nozzle and the oil channel; eight oxygen nozzles are evenly arranged around the four oil nozzles, and the range of the included angle between the axis of the oxygen nozzle and the end surface of the head injector is 45 degrees. The number of oil nozzles, the number of oxygen nozzles, the range of the included angle between the axis of the oxygen nozzle and the end surface of ...

The invention relates to an oil-oxygen burning pre-mixed type starting burner. A head injection part is provided with an oxygen nozzle and an oil nozzle, wherein the oxygen nozzle is connected with an oxygen duct; the oil nozzle is communicated with an oil duct; and an atomizer is arranged between the oil nozzle and the oil duct. In the invention, an oil independent atomization mode is used, so oil can be sprayed out in an atomized mode under an oxygen or oxygen-free condition; and once oxygen is sprayed out, the two media can be mixed and burnt. Thus, the requirements on oil-oxygen pressure and time sequence control in terms of system control are simplified greatly, the regulation range of an oxygen-oil mixing ratio is enlarged considerably, fire is not interrupted, the repeated startingcost incurred by medium supply fluctuation caused by system factors is avoided, the problem that the conventional pre-mixed type burner is susceptible to backfire when starting and stopping is solvedradically, and the damage caused by high-temperature flame to the head injection part is avoided.
Description
technical field [0001] The invention relates to a start-up burner, in particular to an oil-oxygen combustion non-premixed start-up burner. Background technique [0002] my country is a country short of oil and gas and relatively rich in coal resources. Coal-to-methanol, coal-to-oil, coal-to-natural gas, and coal-to-olefins play an important role in the sustainable utilization of energy in my country. The development of coal chemical industry is inseparable from the preparation of synthesis gas. The pressurized gasification of coal is a necessary means to produce synthesis gas. The ignition system of the gasifier is the core component of the equipment. [0003] The existing design principle of the start-up burner has high requirements on the system control, and there are defects that the start-up is not easy to succeed, time-consuming and labor-intensive. The main reason is that the existing products adopt the oil-oxygen premixing method in the burner structure, that is to...
