Abstract

The invention relates to a non-premix type start-up burner. A head jet piece is provided with an oxidant nozzle and a fuel agent nozzle, the oxidant nozzle is connected with an oxidant channel, the fuel agent nozzle is connected with a fuel agent channel, and an atomizer is arranged between the fuel agent nozzle and the fuel agent channel. According to the non-premix type start-up burner, the mode that fuel agents are atomized independently is used, the fuel agents can be jetted out in an atomizing mode under an oxidant condition or a non-oxidant condition, and once the oxidants are jetted out, the two media can be mixed to achieve burning. Thus, the demands to the pressures of the fuel agents and the oxidants and sequential control of the aspect of system control are greatly lowered, the adjusting range of mixing ratio of the oxidants and the fuel agents is greatly widened, fire cutoff is avoided, the cost caused by repeating to drive a car because of supply wave of the media due to system reasons is avoided, the problem that an original premix burner is easy to temper in driving of the car and shutting down of the car is fundamentally solved, and damage to the heat jet piece by high-temperature flame is avoided.

Description

technical field [0001] The invention relates to a start-up burner, in particular to a 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 premixing method in the burner structure, that is to say, the two media of the combust...
