Experimental and Investigation of Tool Design for Reheater

Reheater is a set of pipe coils located in the boiler it starts from high pressure steam to the low pressure and from there to the inter mediate and low pressure turbines. High reheating temperature improve the output and efficiency of a power- plant. They are the same as the super-heaters buy as their exit temperature are a little bit less than super heater and their pressure is 20%-25% less than the super heater they can stand less quality material alloys. The construction of re heater coil bend is consider out by using nipple bended the machine can bend a tube only up to a length 10m. The TIG welding process carried out. Which cost is high and simultaneously cycle time increases. Rectify the difficulties and new die is create a design for R142. Which can be placed over system bender machine by doing so the length of the tube can be increased up to 20m and the STB welding can also be implemented? It cost less than the TIG welding cycle time also reduces and the terminal former mounting in the system bender. Here, the principle of reheater is a rankine cycle. The heat can be converted into heat into mechanical work and the heat can be supplied to the closed loop. This cycle the temp and pressure are in critical stages and the cycle of the temperature can be increased to the critical point.
