METHOD AND DEVICE FOR GASIFICATION OF SOLID COMBUSTIBLE MATERIALS UNDER PRESSURE IN STATIONARY LAYER Russian patent published in 2017 - IPC C10J3/42 

FIELD: technological processes.

SUBSTANCE: invention relates to a method and a device for gasification of solid combustible materials under pressure in a stationary layer. Method for gasification of solid combustible materials by gasifying agents containing oxygen and water vapour is implemented in a stationary layer in a gas generator of high pressure. Through the head part of the gas generator it is supplied with coarse-grained solid combustible materials and the obtained gas is discharged from it. By means of located on the bottom of the gas generator rotating grate, above which there is a stationary layer bed, performed is a controlled supply of first gasifying agents for non-slugging gasification and through the bottom of the gas generator ash is extracted. In addition to the first gasifying agents supplied with the help of the rotary grate and independently from them through at least one nozzle reaching the upper area of the stationary layer filling second gasifying agents for slugging gasification are blown in, herewith the second gasifying agents are blown in with the vapour-to-oxygen ratio of 0.5–4 kg/m³ and the speeds of gas outlet from 20 to 120 m/sec.

EFFECT: higher efficiency, wider range of application of solid combustible materials.
