The present investigations put forth the development of a novel double wall vented rotary fluid heating device. In this device, water is used as a process fluid and is heated by the combustion of sugarcane bagasse. The proposed combustion method is found to provide the use of a more systematic fuel transport system and ensure the efficient heat transfer process to the fluid. It is observed to offer many advantages over the conventional furnaces and obviates the use of any mechanized system such as traveling grate, fluidized bed system, dumping grate, etc. in conventional systems. Also, the heat liberated in combustion is used effectively for heating fluid through a helical coiled tube mounted over the surface of the drum. The present study aims to assess the thermal performance of the proposed rotary combustion chamber at different experimental parameters. It was concluded to have a maximum temperature rise, and the thermal efficiency of this system at 45.3C and 45.2% when drum speed is 6 RPM at Reynolds number equal to 1176.
