MANUFACTURING TRENDS OF GENERATOR GASES FROM DIFFERENT TYPES OF SOLID FUEL

It was concluded from the literature analysis that the production of generator gases from various types of solid fuel has high prospects. The various types of solid fuel with appropriate preparation may include renewable energy sources such as peat, sapropel and municipal solid waste. The authors described disadvantages of modern technologies of production of generator gases and analyzed experience of the production and use of them in the steel industry. The criteria to be met by the new technology of solid fuels were worked out. Therefore, the most promising direction of development of generating gas production technology is the gasification into bubbling slag bath. The scheme of preparation and gasification of solid fuels in the melted slag is described. The conducted technological and economic calculations have shown high economic efficiency of generator gases production in polyfuel gas generator of bubbling type. The production cost of the thermal and / or electrical energy by burning of generator gas produced from raw brown coal is up to 35 – 40 % lower than during their production from natural gas combustion.
