Problems solved by technology
[0004] Since a small part of the process burner nozzle extends into the combustion chamber of the gasifier, the working environment is relatively harsh, and it is affected by factors such as high-temperature radiation, high-speed airflow, coal slurry erosion, high-temperature corrosive gas, and slag erosion, resulting in relatively long service life. Short, the current service life of the process burner is about 70 days, which seriously restricts the long-term stable operation and high-load production of the coal gasification system
After the service period, it needs to be stopped for replacement. Every time the burner is replaced, a certain amount of coal slurry and other raw materials will be lost during shutdown. Therefore, prolonging the service life of the process burner is an effective way to improve the operation cycle of the gasifier and increase the efficiency. One of the ways, it is particularly important for enterprises
Due to the severe blockage of the burner installation hole by the residue, the resistance is relatively large when the process burner is pulled out for each maintenance, which will cause damage to the cooling water coil

The invention discloses a jacket cooling type process burner for a coal water slurry pressurized gasifier. The jacket cooling type process burner comprises a burner body, a gas inlet formed at the upper end of the burner body, a spray head component positioned at the lower end of the burner and a cooling water jacket surrounding the outer side of the burner body. In the invention, by adopting jacket cooling, the flow area of the cooling water can be increased, the heat exchange efficiency is improved, and better cooling protection is provided for the burner; the channel annular spaces in the burner are optimized to meet the needs of different coal types and realize a better atomization effect, and the carbon transformation rate is increased; and by adopting a high-strength wear-resistant material resistant to high temperature and corrosion, the service life of the process burner can be prolonged.
Description
technical field [0001] The invention relates to a process burner, in particular to a jacket-cooled process burner for a coal-water slurry pressurized gasification furnace. Background technique [0002] Since its birth, coal-water slurry gasification technology has been widely used in the field of coal chemical industry through continuous exploration, research and continuous improvement and development. Among them are representative multi-nozzle opposed coal-water slurry gasifiers, Tsinghua water-walled coal-water slurry gasifiers and Texaco coal-water slurry pressurized gasifiers. With the vigorous promotion of clean coal utilization technology in the country, the pressurized gasification technology of coal water slurry has been developed rapidly in my country. Its main advantages are: stable and reliable operation of the device; high degree of automation; flexible operation control; high coal gasification efficiency ;Advanced process indicators; superior environmental prote...
