摘要： Disclosed is a heat exchanger component and a heat exchanger system comprising a plurality of heat exchanger components of this type, for the temperature control of a gas flow with solid particles, and a device for producing a combustible product gas from carbon-containing input materials, with a heat exchanger system of this type. Gas flows which are mixed with solid particles occur in the form of flue gas, as a product gas stream and similar. The hot gas flows comprising solid particles must generally be cooled. If this cooling is carried out in conventional liquid-gas heat exchangers, there is a danger that the solid particles will be partially deposited in the heat exchanger and thus significantly reduce the efficiency of the heat transfer. Through gas inlet and gas outlet opening transversely and tangentially into the flow channel, a screw thread-shaped stream occurs inside the flow channel around the middle of the main body. In this way, the flow velocity of the gas flow comprising solid particles is very high in the vicinity of the gas inlet, so that the Prandtl boundary layer on the inner side of the cladding of the main body is comparatively thin. This significantly increases the heat transfer between the gas flow and the cladding, i.e. the outer side of the cladding releases more heat to the environment. Because of the high centrifugal forces, the solid particles also concentrate in a narrow region on the inner side of the cladding, so that the probability of particle collisions and the caking of smaller particles into larger particles increases sharply. Larger solid particles are easier to separate in downstream filters. Finally, due to the high flow velocity and the turbulent flow connected therewith, the depositing of solid particles on the inner side of the cladding, which is a risk in the case of laminar flow, is also prevented.

摘要： The invention relates to a downdraft fixed-bed gasifier for generating a product gas from pourable biomass particles, to a method for operating such a downdraft fixed-bed gasifier, to a method for starting such a downdraft fixed-bed gasifier, and to a method for shutting down such a downdraft fixed-bed gasifier. By supplying air through the bed of biomass particles in the tubular gasifier component, a uniform distribution of the air is produced. Hardly any temperature differences occur in the oxidation zone by virtue of the uniform distribution. As a result, even pyrloysis gases produced over the oxidation zone flow through the oxidation zone in a uniform manner. The uniformity of the gas and the air flows allows a product gas to be generated with low tar quantities. The oxidation zone is locally connected by means of a cross-sectional jump between the gasifier component and the gasifier container at the open end of the gasifier component, different flow speeds resulting from said cross-sectional jump. By expanding the cross-section, the flow speed is slowed compared to conventional fixed-bed gasifiers. The different flow speeds within and outside the tubular gasifier component virtually fix the oxidation zone in front of the open end of the tubular gasifier component. Another advantage of the expanded cross-section is that the pyrolysis gases are not delimited by a tube wall while flowing through the oxidation zone. The flow conditions on tube walls are not uniform, and thus the temperatures there are not uniformly high. When pyrolysis gas flows on the edge of a tube wall through the oxidation zone, as is the case in the prior art, the long-chain hydrocarbons are not completely broken down. Additional long-chain hydrocarbon compounds are broken down by virtue of the absence of the tube wall, thus leading to an improvement of the motor efficiency when using the product gas.
