RAJ WASTE HEAT RECOVERY BOILERS DESIGN AND DRAFTING
Waste Heat Recovery Systems are DESIGN for catalytic cracking plants for the production of Ammonia, Methanol, Town Gas and Hydrogen. They utilize the fuel gas heat from the furnace heating and provide process gas cooling by means of Steam Generation and preheating of the medium used as well as of the feed and process water.

A novel flue gas waste heat recovery system for coal. The thermal energy of exhaust flue gas dumped into the environment accounts for approximately 50%–80% of a boiler's thermal loss, and 3%–8% of the plant total energy input. Obviously, there exists a great potential to improve the efficiency of the power plant by the recovery of the waste
