Title:
TEST SYSTEM AND METHOD FOR MEASURING UNDERGROUND COAL GASIFICATION EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2023/208248
Kind Code:
A1
Abstract:
Provided in the present invention is a test system and method for measuring underground coal gasification efficiency, relating to the technical field of underground coal gasification. The test system comprises a gasification agent supply system, a gasifier, an outlet, a recycling system and a monitoring system. Generally, the gasification agent is injected into the gasifier, then the gasifier is ignited at a high temperature to chemically react with coal to generate gas. The gas passes through the outlet and the recycling system, and the content and amount are measured. The monitoring system monitors the operation state of the gasifier, the injection and gas production conditions of the gasification agent, the temperature change in a gasification channel, the ignition temperature, and the pressure gauge data. In the invention, the gasification product and the amount are monitored by means of changing the injection of different gasification agents or changing the temperature in the gasification channel, so as to determine the gasification conditions that generate more useful gases.
