[PDF] Application Of Economizer For Waste Heat Recovery From Exhaust Flue Gas In Steam Boiler…

In the present work, the useful concept of energy utilization is analyzed and implemented to the steam boiler system. Energy flows in the steam boiler system have been shown in this work. Energy efficiency and losses have been determined as well. Energy losses are found to be 18.88%. 7.37 % of the total losses is emitted by a waste heat of exhaust flue gas. This work also presents a case study
