The paper presents the results of studies of the effect of gasification pressure on the composition of the producer gas from different types of coals. Calculations of gasification process with determining the main indicators for different coals depending on the pressure and the recirculation fraction of the producer gas were carried out. The results of studies have shown that the elevated pressure and fuel heating by recirculation gases in combination with high values of gasification temperature and the use of oxygen or steam-oxygen blowing promotes to increase the calorific value of the producer gas, to reduce the time of the process and the gasifier sizes, which leads to improvement of conditions and intensification of the process.
