Abstract

A burner for a pulverized coal gasifier. The present invention relates to a burner. The present invention solves the problem of complex manufacturing process, high manufacturing cost, inconvenient disassembly and maintenance, and The problem of short service life, which includes at least one layer of shielding gas pipeline, gasification agent pipeline, pulverized coal pipeline, first swirl blade, second swirl blade and flange; gasification agent pipeline is sleeved on at least one layer of protection Outside the gas pipeline, the pulverized coal pipeline is sleeved outside the gasification agent pipeline, the flange is sleeved on the outer wall of the pulverized coal pipeline, and the first swirl vane is set on at least one layer of the outer wall of the protective gas pipeline and the inner side of the gasification agent pipeline Between the walls, the second swirl vane is set between the outer wall of the gasification agent pipeline and the inner wall of the pulverized coal pipeline, and the top of the pulverized coal pipeline is provided with a pulverized coal airflow inlet, and the top of the gasification agent pipeline is provided with a gas flow inlet. The inlet of the protective gas is provided at the top of at least one layer of the protective gas pipeline. The invention is used in a coal gasification device.

Description

technical field [0001] The invention relates to a burner, in particular to a burner for a pulverized coal gasification furnace. Background technique [0002] Coal is an important energy source, but for a long time, the use of coal has been accompanied by serious environmental pollution problems. In recent years, people have paid more and more attention to clean coal technology aimed at reducing pollution emissions and improving utilization efficiency; and coal gasification technology is an efficient and clean clean coal technology. The burner is the key component of the coal gasification device. The burner is in a high-temperature environment for a long time, and it is very easy to burn out. Once the burner is burned out, the gasification device must be shut down, causing huge economic losses to the enterprise. Chinese Invention Patent Application Publication No. CN1710333A discloses a swirl burner, in which three-stage water-cooled jackets are arranged coaxially in sequen...
