Title:
【発明の名称】乾式フィード方式と湿式フィード方式の同時ガス化による難スラリー化固体炭素質原料のガス化処理法
Document Type and Number:
Japanese Patent JP3072586
Kind Code:
B2
Abstract:
PURPOSE: To enhance cool gas efficiency to thereby improve gasification performance and safely perform gasification operation by gasifying a hardly slurriable solid carbonaceous material by wet feed system and simultaneously gasifying an easily slurriable solid carbonaceous material by wet-feed system in a process for gasifying a soild carbonaceous material by partially oxidizing it in the presence of oxygen. CONSTITUTION: A hardly slurriable solid carbonaceous material is fed to a dry grinder 1 to be ground therewith into fine particles and then fed through a lock hoppper feeder 2 to a gasification burner 12a. An easily slurriable solid carbonaceous material is fed to a wet grinder 4 to be ground therewith in the presence of water and fed to a gasification burner 12b. Simultaneously, pressurized oxygen as the gasification agent is fed through an oxygen feed line 8 to a gasification oven 9. The conditions of partial oxidation in the reaction chamber 10 are at a temp. of 1400-1450 deg.C, a pressure of 30-100kg/cm<2> , and for a dwelling time of 2-10sec. The resultant gas 13 is taken out through a take-out port 17.
