    Opis:
    This paper presents a concept and a technical analysis of a co-generation power set with a combustion engine powered by syngas produced in the process of wood waste gasification. The set is composed of a wood waste gas generator fitted with a filter system, a combustion engine, a current generator and heat exchangers. The foundations of the gasification process are described together with the most common solutions used worldwide. Moreover, the methods of adapting spark-ignition and compression-ignition engines to be powered by syngas produced in the wood waste gasification process are presented. The advantages of the presented solution and its possible applications in industry are shown. The assumed technical parameters of the set are as follows: mechanical-electrical energy – 200 kWh, heat recovered from the gasifier – 250 kWh, heat recovered from the engine – 200 kWh. The concept and design of the module cogeneration set is the effect of actions taken by the Institute of Automobiles and Internal Combustion Engines and by the Institute of Thermal Power Engineering of the Cracow University of Technology.

    Opis:
    The article presents possibilities of implementation gas, came by wood biomass gasification, to run on internal combustion engines powered normally by Diesel fuel. Carbonization, gasification and burning effects were introduced. Main processes occurring during biomass gasification were shown. Basic chemical reactions characteristic to each stage were named. The differences in composition of received gas according to sort of biomass, gasification medium and type of generator were mentioned. In article were depicted way of modus operandi and structures of typical generators along with its advantages and disadvantages. gas properties obtained by this method and its main parameters were presented. The advantages and disadvantages posed by the use of wood gas in internal combustion engines were described. Parameters of the gas that should be amended to allow the engine to be powered were listed. Also were shown ways of changing these parameters. Necessary engine modifications to be able to supply it with wood gas were presented. The article finishes with conclusions and risks resulting from the use of this technology and also possible impact on the environment.

    Opis:
    This work aims at study the effect of the operating conditions like equivalence ration and temperature on the updraft gasification of beech wood. The main aspects was to analyze the influence of temperature distribution in the reactor and equivalence ratio on the fuel consumption, syngas composition as well as tar formation characteristics during the gasification process. The light tar content and composition were analysed using gas chromatography coupled with mass spectrometry (GC-MS). Experimental results have shown that the amount of air supplied does not affect the parameters of the gasification process linearly. For lower ER value there was high fuel consumption and high bed temperature in the gasifier, which results in high caloric value of syngas. The results showed that tar yield during updraft gasification depends on the temperature and equivalence ratio. With the increase value of ER and the decrease of temperature on the surface of the bed, the total amount of tar yield increased. The highest temperature on the surface of the bed leads to the smallest tar yield, which can be associated with thermal cracking. The results indicate that both light and heavy tar are changing nonlinearly with different operating conditions. In addition, with decreasing temperature and increasing ER values, the amount of phenol and oxidized aliphatic compounds in the tar samples increased while the BTEX amount decreased. The amount of PAHs, in relation to the temperature and ER, was kept low in all cases.
