BOILER FOR RECOVERING WASTE HEAT HAVING PIN TUBE SLIDING GUIDE

摘要

PURPOSE: A boiler for recovering waste heat having a pin tube sliding guide is provided to smoothly slide a pin tube through a pin tube insert hole of a pin tube support, thereby restraining the pin tube from being restricted by the support when vibration and thermal transformation are generated in the pin tube. CONSTITUTION: A support frame(7) supports a header(6). A pin tube(1) absorbs heat from burnt gas. A support(3) supports the pin tube. The header collects the burnt gas flowed through the pin tube. A sliding guide(5) slides the pin tube in an axial direction. The sliding guide is formed of two semicylindrical sliding guide blocks and is fixed at the pin tube by fixing bolts combined with coupling bolts inserted into spiral through holes and thereafter inserted into coupling holes.
