Abstract:
This article presents one of the basic energy technologies used to increase the share of renewable energy sources in the overall balance of the fuel. The technology of biomass gasification, which enables the production of electricity and heat from the primary renewable fuel, which is biomass, is presented. The possibility of using process gas produced in the reactor in, among others, piston engine or gas turbine is discussed. Special attention was paid to the basic parameters characterizing the process gas, such as: gas composition, lower heating value, temperature, moisture content and impurities. The amount of dust and organic impurities contained in the gas determines its suitability for supplying to combustion engines or gas turbines. The paper presents the basic methods for process gas purification. The limits of dust and organic pollution pose primarily to internal combustion engines are discussed. A research installation of the Institute for Chemical Processing of Coal in Zabrze (Poland) to examine the process of biomass gasification and process gas purification installation used is presented . The scheme of the gasifier with fixed bed is shown (60 kWt). Main technological parameters of the generator and the composition of the gas produced along with its impurities are characterized. The distribution of temperature in the reactor and the temperature of the produced process gas are shown. Gas cleaning system consisting of a cylindrical expander, cyclone, heat exchanger, coke adsorber and fabric filter is shown in details. Results of experiments on the effectiveness of various gas cleaning devices are presented.
