Waste Heat Recovery System & ID Fan Installation
Design, supply and installation of a waste heat recovery unit and Induced Draft (ID) fan system for an agro-processing plant in Bhaktapur, aimed at improving combustion efficiency and cutting fuel consumption.
ME Engineering carried out an energy optimisation project for Green Line Agro in Bhaktapur, Nepal, supplying and installing a waste heat recovery system together with an Induced Draft (ID) fan to improve boiler combustion efficiency and reduce fuel costs.
The project addressed two linked goals at the plant: recovering thermal energy that would otherwise be lost in flue gas, and improving draft control through a properly sized ID fan. The waste heat recovery unit (WHRU) captures residual heat from flue gases and uses it to pre-heat feed water or combustion air (confirm with owner), reducing the fuel input needed to reach steam-raising temperature. The ID fan improves furnace draft and flue gas extraction, supporting more complete combustion and stable boiler operation.
Together, these upgrades are intended to lower specific fuel consumption, reduce flue gas losses, and improve overall plant efficiency, while supporting more consistent steam output for Green Line Agro’s processing operations.
What we delivered
Equipment & ratings supplied
Green Line Agro’s existing boiler system was losing usable thermal energy through flue gas exhaust, and draft control limitations were affecting combustion efficiency, leading to higher fuel consumption and operating costs.
ME Engineering designed and installed a waste heat recovery system paired with a correctly sized ID fan, recovering flue gas heat and improving draft control to support more efficient, complete combustion.
