1. Introduction. The temperature of boiler exhaust flue gas normally ranges from 120 to 150 °C in coal-fired power plant (CFPP). The heat loss of exhaust flue gas accounts for approximately 5080% of the total boiler heat loss and 38% of the total energy input of CFPP .This means that recovering waste heat from boiler exhaust flue gas could improve boiler efficiency and reduce emitted
Learn More2019-5-3·Waste heat is a valuable resource. Johnston Boiler Companys line of single and triple pass Waste Heat Recovery (WHR) boilers offer your company a way to save valuable energy, energy typically lost in waste heat. The WHR se-ries are used in petrochemical plants, refineries, steel mills, ore converters, brick or cement plants, glass works, and
Learn MoreOtherwise, the exhaust gas boiler could be used in oil/gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine. Generally, the exhaust gas boiler is installed in gas duct, generate steam by absorbing the flue gas waste heat, and decrease the exhaust gas temperature.

As a China waste heat boiler manufacturer, Our products are widely used in chemical, cogeneration (combined heat and power) plants,fertilizer plant, coking, etc.
Learn MoreWaste Heat Recovery Boilers (WHRB) - Wastetherm is manufactured by Thermodyne- are designed to recover heat from waste flue gases from DG exhaust, Furnace exhaust to produce steam or hot water. WHRB, industrial boilers are advanced enough to deliver max possible heat recovery & save money.
Learn More2017-5-4·Waste Heat Recovery for the Cement Sector . 1 Waste Heat recovery (WHr) is a proven technology, but until now WHr uptake has been limited except in China. As early as the 1980s, Japanese companies spear-headed the introduction of WHR power systems in the cement industry. Currently, there are a range of commercially-
Learn MoreWe are designing economizer for waste heat recovery boiler and that waste heat is taken from coke oven batteries. Waste heat recovery boiler uses waste flue gases for steam production, so this economizer is also work on these varying parameters like gas flow rate, temperature variation, pressure variation, amount of ash content in flue gases.
Learn MoreDepending upon the amount of waste heat available and the process where you want to utilize this waste heat say for an instance for producing steam, the required capacity and pressure of steam will help to determine the design of a waste heat boiler. Waste Heat Recovery Boilers (WHRB)Benefits : Highly Reliable in operation and robust in
