Fin Tube Fixing Device for Combined Gas Horizontal Flow Waste Heat Recovery Boiler

摘要

The present invention relates to a fin tube fixing mechanism of a gas horizontal flow type waste heat boiler for a composite power generation, and a conventional fin tube fixing mechanism overlaps two support plates formed with grooves into which a pin tube is fitted inside a band plate forming an outer frame. The support plate is of a certain thickness so that the excessive weight of the support plate itself after completion will affect the durability of the entire waste heat recovery boiler duct, and also the problems of manpower and cost for drilling the groove and the surface area of the fin tube. There is a somewhat reduced problem, in the present invention, the upper flat bar fixed by arranging side by side in a diagonal direction with a predetermined interval as the pin tube diameter at the top of the band plate and the upper part at a predetermined interval as much as the pin tube diameter at the bottom of the band plate again. Lower flats aligned side by side with flat bars And, it is configured to adjust the width of the band plate in response to the required rigidity of the waste heat recovery boiler duct, it is easy to process the flat bar, the overall structure is simple and robust, and in particular, the weight of the fin tube fixing mechanism itself can be reduced, The durability of the waste heat recovery boiler duct is improved, the manufacturing cost is low, and the necessary rigidity of the fin tube fixing device itself can be adjusted according to the capacity of the waste heat recovery boiler or the flow rate of the exhaust gas.
