HEAT RECOVERY SYSTEMS FROM WASTE HEAT
3.3 T/h, 6 bar Waste Heat Steam Boiler
Heat Recovery by hot flue gasses which are thrown out of steam boiler, thermal oil boiler, glass, melting or drying furnaces, can be obtained to heat boiler feed water, hot water for radiators, hot water for domestic purposes, for industrial process machines.
SKU: EWA-TR-UNI-45-MEEPZNQHot air for combustion, environmental purposes, process air and for other industrial process. It should not be forgotten that 1% efficiency of the device increases by decreasing each 20°C temperature of hot flue gasses.
Design of heat recovery devices:
They are manufactured in different designs according to their conditions of use and properties of fuel burned. Basing on their conditions of use, economizers are manufactured by straight seamless type tubes, finned type tubes, 316L stainless steel tubes.
In thermal oil boiler :
Flue Gasses Temperature is approximately = Thermal Oil outlet temperature +100°C. In the above example it becomes 350°C.
Thermal oil boiler containing air pre-heating system
A Thermal Oil Boiler burning Natural Gas can supply hot air for combustion at 250°C through air preheater decreasing chimney temperature up to 120°C. Boiler Efficiency will show 11.5% increase.
