Gasification reactors are devices for thermochemical biomass treatment. In such reactors, complex of mass, and heat exchange, interphase, and chemical processes occur. Designing a mathematical models of processes occurring in such devices requires expensive research, and leads not always to satisfying results. Moreover, some authors executed complex computational simulations of gasifying process aiming to approximate calculation of: composition of generated syngas, temperatures level in the reactor, and even simulations of two-phase flow of gas enriched in pollutants. In given article the initial research of prototype downward gasification reactor feed by model feedstock – wood pellets, has been presented. The construction of the reactor has been described. Particular parts of the reactor has been shown, and the concept of reactor controlling has been given. The gasification reactor tightness has been examined by testing the generated pressure in gasification chamber. Executed research aimed on testing the correctness of particular elements of the reactor work, and determination of motion characteristic for wide range of technological parameters. Static characteristics of bed temperature in the oxidation zone, and the converted biomass stream in function of gasifying agent have been determined. Additionally, the characteristics of removed carbonizate stream in function of grate rotation rate has been determined. In the further experiments the dynamic characteristics of gasification process in the prototype reactor will be tested. The composition of syngas generated from hardly treatable waste materials will be measured. Determined characteristics will be used for further experiments on designing of process control algorithms.
