Fin Tube Arrangement Fixture for Combined Gas Horizontal Flow Waste Heat Recovery Boiler

摘要

The present invention relates to a fin tube arrangement fixing mechanism of a gas horizontal flow waste heat recovery boiler for a composite power generation, and a conventional fin tube fixing mechanism overlaps two support plates sheeted to fit a group of fin tubes in a band plate to which the fin tubes are fixed. Or welded to each other, but due to its poor scalability and considerable weight, it affects the durability of the waste heat recovery boiler. When the load is concentrated on the support plate due to the formation of a sudden strong exhaust gas stream in the waste heat recovery boiler, In contrast, in the present invention, the connection plate is bent in the band plate to be fit between the gaps between the pin tubes to be fixed in the band plate. Waste heat recovery consisting of welded joints to contact points in contact with other members The support load to be operated under the sudden environment in the boiler is distributed, and the processing of only a few bends of the flat plate is distributed to distribute many welding points to strengthen the support function of the pin tube and to reduce the manual labor due to the simple configuration. It also has an excellent effect such as advantageous in terms of operation after installation such as maintenance.
