Description: Das Projekt "Two stage gas generator for industrial wastes" wird vom Umweltbundesamt gefördert und von Eisenmann Maschinenbau KG durchgeführt. Objective: Thermic utilization of industrial residual system resp. production residues in a two stage incineration system under production conditions. The tests contain as well pre-trials for determination of the optimal system parameter as also permanent trial runs, for establishing of material and energy balances and for judgement of the operation reaction through a longer time period. By the work with this process the advantages shall be shown: - Profitability also with small residual material amount of 200-1000 kg/h - complete energetic utilization of the material - easy integrating in available heating systems, for example preswitching of an available boiler system - universal usability of energy - utilization of the product residues in the own factory for heating, process heat and evtl. electric current generation - reduction of the removal costs. General Information: The demonstration system, built in the smallest production scale, had been erected in the technical science department of the Company EISENMANN. The process principle is based on a mechanical pre-treatment, with which the material will be communited with a slitting rollers appliance and afterwards will be transported into a storage silo. From the silo the filling system continuously pushes in the waste material in the fluidized bed reactor, which has a quadratic free cross section of 500 x 500 mm and is provided with a 400 mm thick fireproof lining. A 1 m high piling up of quartz sand with a grain size of 0,4-1,6 mm serves as heat bearer medium. The piling up will be fluidized by the injection of hot flue gases. The advantages of a fluidized bed as pyrolytic stages are the following: - The fluidizing of the sand causes a uniform distribution of temperature - an intensive heat transition between sand and residual material is given - by the fluidizing a mechanical comminution of the material simultaneously takes place, with that the lump forming of the used material will be avoided - by a low oxygen, preheated fluidized gas a pyrolisation with under stoichiometric incineration takes place so, that a max. reaction temperature of approx. 600 degree of Celsius up to 700 degree of Celsius arises, with which still no slag forming appears. The following thermic processes proceed: The hot flue gases (approx. 650 degree of Celsius) contain 6-8 per cent oxygen. They hold the sand bed on approx. 550 degree of Celsius. The supplied residual material combustes in these conditions under stoichiometric. Through a short insulated connection line the pyrolitic gases reach in a vertical arranged combustion chamber. Here they will be burned with the help of a support burner by injection of fresh air with approx. 1100 degree of Celsius. Following the combustion chamber the flue gases will be diverted horizontally, before they give away again in a vertical heat exchanger their energy to a hot water circulation. After the heat exchanger the flue gases are still approx. 250 degree of Celsius...
