Waste Heat Recovery using Phase Change Material Coupled Steam Generator

Mayank Giri ^[2] | Ankur Agrawal ^[2]

Abstract: In order to allow the Waste Heat Recovery from the molten slag produced as a by-product in steel industries, a new type of waste heat recovery system based on use of Phase Change Material is proposed. An improvisation of Waste Heat Recovery system, in addition to previously proposed ideas is presented. A Rotary Cup Atomizer is used for granulation of molten slag and to bring down the temperature of the molten slag to a working range. The heat of slag is recovered using fluidized bed heat exchanger and further used to generate power by using Phase Change Material Coupled steam generator. A system combining Phase Change Material and Heat Transfer Fluid is used to smooth-off gas temperature profiles entering the steam generator. The Waste Heat Recovery system using Phase Change Material exhibits a great potential in the field of power generation from the untapped energy available in molten slag.
