Gas supply system of gasification furnace

Abstract

The invention provides a gas supply system of a gasification furnace. The main continuous gas supply gas storage tank and the standby continuous gas supply gas storage tank which are connected in parallel are adopted, during normal use, the main continuous gas supply gas storage tank supplies gas to continuous gas utilization equipment, and when the main continuous gas supply gas storage tank breaks down, the standby continuous gas supply gas storage tank replaces the main continuous gas supply gas storage tank to supply gas to the continuous gas utilization equipment. According to the continuous gas supply device, the situation that gas supply to the continuous gas utilization device is affected when the main continuous gas supply gas storage tank breaks down can be avoided, the reliability of gas supply to the continuous gas supply device is improved, continuous gas supply and intermittent gas supply are separated, and when the gas quantity of the intermittent gas supply gas storage tank is not enough, the gas supply to the continuous gas utilization device is not influenced. Gas in the standby continuous gas supply gas storage tank can also enter the intermittent gas supply gas storage tank to be supplemented, the nitrogen supply pressure of the main continuous gas supply gas storage tank is reduced, and the requirements for continuous gas utilization equipment and intermittent gas utilization equipment are guaranteed through the arranged continuous gas supply pressure adjusting mechanism and intermittent gas supply pressure adjusting mechanism.

Description

technical field [0001] The invention relates to the technical field of gasification, in particular to a gas supply system for a gasification furnace. Background technique [0002] Coal gasification is the core technology for clean and efficient utilization of coal. It is the process of developing coal-based bulk chemicals and liquid fuel synthesis, advanced integrated coal gasification combined cycle power generation system, polygeneration system, hydrogen production, fuel cells, and direct reduction ironmaking. The foundation of industry is the key technology, core technology and leading technology for the development of these industries. [0003] At present, the gas supply system of the gasifier needs to stop the gas supply when the gas storage tank used to store high-pressure nitrogen fails during use, which in turn affects the gas supply and use of the gas equipment. At the same time, during the gas supply process , for the lack of adjustment of the gas supply pressure,...

Problems solved by technology

[0003] At present, the gas supply system of the gasifier needs to stop the gas supply when the gas storage tank used to store high-pressure nitrogen fails during use, which in turn affects the gas supply and use of the gas equipment. At the same time, during the gas supply process , the lack of adjustment for the air supply pressure makes it difficult to meet the demand for air supply pressure of gas equipment
