Problems solved by technology

For example, due to problems such as wear and erosion, the life of a single burner is short, and it is difficult to achieve long-term stable operation, and once the burner fails, the entire gasification device will stop immediately, causing great losses
[0004] In addition, when a single gasification unit reactor is scaled up to more than 2000t level, a single start-up preheating burner is used to raise the temperature and pressure of the gasification unit reactor during feeding, which takes a long time and affects the efficiency of feeding operation

Abstract

The invention discloses a gasification device with multiple burners and a coal gasification technology. The gasification device comprises a gasification furnace reaction chamber, a main burner, which is arranged on the center of the top of the gasification furnace reaction chamber, and auxiliary burners, which are arranged on the periphery of the main burner. The auxiliary burners are provided with a plurality of connection channels and also provided with control valves for switching the connection channels between the ignition working mode and the technological material feeding mode. The provided technical scheme can shorten the furnace warming time, and achieves the stable operation of gasification device in a long term.

Description

technical field [0001] The invention relates to the field of coal gasification technology, in particular to a multi-burner gasification device and a coal gasification technology. Background technique [0002] Coal gasification is a clean coal combustion technology developed in recent years, which has been more and more widely used, including coal-water slurry pressurized gasification technology and pulverized coal pressurized gasification technology. Among them, the gasification device is the key equipment of coal gasification, and the burner is an important core component of the gasification device, which has an important impact on the operation performance of the gasification device. [0003] In recent years, large-scale and high-pressure gasification devices have become the development trend of coal chemical industry. Multi-burner configuration is essential, but the service life of burners restricts the long-term stable operation of gasification devices. For example, due...
