The aim of this paper is to introduce readers (listeners) to the basics of gasification process, high temperature fuel cells with solid electrolyte and particularly with the problems of high-temperature gas cleaning system of the producer gas from gasification of woody and agricultural biomass and/or alternative fuels (e.g. refuse derived fuel) to the level needed for its use in combined production of heat and electric power in high-temperature fuel cells with solid electrolyte (SOFC).

The paper focuses on the assessment of using ligno-cellulosic biomass in a fluidized bed gasifier, available within a distance of 50 km, in units with capacity approximately 3 MWe. The main objective of the experiments was to evaluate the effect of partial replacement of inert bed material (sand) with a material catalytically active (dolomitic limestone) on the composition and purity of produced gas and the input fuel energy conversion into the energy chemically bound in the producer gas.

Fuel is gasified by thermochemical conversion into producer gas using an appropriate medium at high temperature in a gasification generator. The aim of this study was to compare the suitability (reactivity) of selected types of coal in several fluid generators under the well defined conditions. Producer gas obtained by coal gasification was compared, especially, in terms of calorific value and yield of gas, cold gas efficiency, the yield of major and minor components of gas, tar yield and conversion fixed carbon into the generator gas.
