Abstract

The invention discloses an oxygen feeding control system and a gasifier feeding system thereof. The oxygen feeding control system comprises an oxygen flow establishing system and an oxygen charging system. A pipeline of the oxygen flow establishing system is connected with the oxygen charging system from an oxygen source through a first remote control valve and an oxygen flow adjusting valve in sequence. A pipeline of the oxygen charging system is divided into at least two branch pipes after passing through a first stop valve and a second stop valve sequentially, and each branch pipe is connected with a nozzle through a branch pipe throttling element. The gasifier feeding system comprises the oxygen feeding control system. By means of the oxygen feeding control system and the gasifier feeding system thereof, the hardware investment on valves and metering systems in a set of oxygen feeding control system is greatly reduced, then, the cost of investment on a whole gasifier system is reduced, the operation intensity and complexity of the system are lowered, the probability of system fault shutdown caused by partial damage of the valves and the metering systems is reduced, and the reliability of the whole gasifier feeding system is enhanced.

Description

technical field [0001] The invention relates to an oxygen feeding control system and a gasification furnace feeding system thereof. Background technique [0002] The coal gasification process uses oxygen (air, oxygen-enriched or industrial pure oxygen) and water vapor as the gasification agent to convert the combustible part of coal or coal char into combustible gas through chemical reaction under high temperature and pressure. Among them, entrained bed gasification technology has become the mainstream technology of coal gasification because of its good technical indicators, high processing load and environmental friendliness. Among them, the multi-nozzle opposed coal gasification technology is one of the mainstream international advanced large-scale coal gasification technologies. It has been widely used in industries due to its unique large-scale advantages, excellent process performance and safety and reliability. [0003] The characteristic of multi-nozzle opposed gasif...
