Waste heat recovery from Industrial Ovens, Kilns & Calciners
Corrosion and fouling limit heat recovery. Polymer economisers and air preheaters are corrosion resistant and fouling can be easily cleaned.
Prevent fouling & corrosion
Your Oven, Kiln or Calciner has additional waste heat recovery potential
Improve oven efficiency
The oven efficiency can be improved by using a polymer air preheater or economiser.
Lower CO2 emissions
Every 1% efficiency increase of your Oven, Kiln or Calciner results in 1% CO2 emission reduction.
Decrease fuel costs
The additional heat that is recovered is applied to heat up air entering the oven or heating up process water. Therefore, fuel consumption is reduced.
Waste heat recovery on Industrial Ovens, Kilns & Calciners is limited by corrosion and mechanical failures
Waste heat is lost via the stack
The required heat in Ovens, Kilns or Calciners is generated by firing fuels like natural gas, hydrogen rich gas, fuel oil. The heat loss can be significant. Recovering this heat can be challenging due to the fouling and sometimes corrosive character of the exhaust air, product vapours and flue gas.
Corrosion and fouling problems
Hot exhaust air and flue gas from Ovens, Kilns or Calciners are vented into the atmosphere. The exhaust air or flue gas may contain: combustion products from the fuel, components released from the processed products and dust particles. In general, the exhaust air and flue gas tend to be fouling and/or corrosive due to the components present. When the flue gas is cooled to recover heat, the acids will condensate and fouling accumulates.
