How To Calculate Waste Heat Recovery Boiler Thermal …

There are two methods to calculate a waste heat recovery boiler thermal efficiency, Positive Balance Test and Anti-Balance Test. Positive balance test is to directly measure the mass flow, eroded and fuel consumption, low calorific value and others, then in accordance with the ratio to work out the boiler efficiency, that is effective utilized heat and fuel input heat ratio.
