Experimental studies of biomass gasification installation consisting of a new gasifier and gas cleaning system

The article presents the issues related to the possibility of using biomass for energy purposes. Particular attention is given to the gasification process of one of the key renewable energy sources in Poland, which is the biomass. An experimental research installation for biomass gasification is presented. The installation consisting of reactor, gas purification installation and auxiliary devices is described. The installation was designed and built in the Institute for Chemical Processing of Coal in Zabrze (Poland). Construction of a new gas generator GAZELA, developed by the Institute for Chemical Processing of Coal was described in details. It is a 3-zonal moving-bed reactor working in overpressure. Gasifier is a vertical, cylindrical reactor, inside which in the axis of the apparatus there is a tube for discharging of the generated gas. The operational experiences from the conducted technological tests are presented. Fuels used for test are characterized. Producer gas cleaning installation is presented. Temperatures occurring in the characteristic points of the installation with particular emphasis on temperature inside the reactor are shown. The composition of the gas obtained during the tests, together with dust and organic impurities is presented. Exemplary timelines of temperature and gas composition variations are shown.
