Exhaust Gas Economizer for Waste Heat Recovery

Jiema Exhaust Gas Economizer for Waste Heat Recovery, also Economiser in a Boiler or Economiser Coil, is designed product specifically for waste heat recovery. The heat exchange element of the Exhaust Gas Economizer is made of steel tube-aluminum "L"type finned tube, and its working temperature can reach 230℃.

Economiser in a Boiler has the edge of tight contact, no wrinkle, no dust accumulation,good vibration resistance, and will keep the pipe from air erosion. Compared with the steel radiator, the heat dissipation area for Economiser Coil is increased by 10-20%,the weight is reduced by about 30%,and the heat can be increased by 10-20% under the same working conditions. It is suitable for steam and hot water systems. It can be widely used in air heating, material drying and air conditioning systems.

Materials of Exhaust Gas Economizer

Heat Exchange Tube and Fin

Selection principles, steel standards, thermal treatment states and permissible stress values of the materials of the pressure parts should be subject to requirements of the GB 150. The pressure parts used in inflammable, fatal or toxic operating environments should be made of cast iron.

The common tube materials include carbon steel Q235B, SS304, SS316, copper tube, etc.

The common fin materials include carbon steel, SS304, SS316, aluminum, etc.

FAQ for Economiser in a Boiler

1.Where can Economiser Coil or Exhaust Gas Economizer be useful?

Finned Tube Heat Exchanger like Exhaust Gas Economizer and Economiser Coil can be applied to situations where temperature ranges -20-650degree. Pressure is 0-4MPa for inside the tube and 0-1MPa for outside the tube. Concerning the fluids, they could be liquid, steam, vapor, compressed air, flue gas and others.

2.Why would I select Economiser in a Boiler but not others?

The advantages of Economiser in a Boiler lie at its high heat transfer area,.which is ten times of bare tube's. Therefore, it not only increases efficiency but saves cost as well if heating the same amount of air.
