A test system for the pressurized coal gasifier was 0 引言 described, and the study processes and results of the test were 我国煤炭的特点之一是气化难度较高的双高 given. The feasibility of flameless gasification inside the 煤种(高灰熔点，灰熔点tFT1 450 ℃；高灰分，平均 gasifier was validated from the gasification reaction images, which accord with the characteristic of flameless oxidation. 含灰分 23%)煤种储量多，其中高灰熔点煤约占我 The key gasification parameters were obtained from the 国煤炭储量的50%；但目前从国外引进的先进气流 measured tempera
