Boiler efficiency can be calculated using ASME Performance Test Codes (PTC). PTC 34 is used for waste combustors with energy recovery using the boiler as a calorimeter. Using this method, the heat outputs, losses and credits must be calculated. Heat credits correct the efficiency to standard ambient conditions, such as air temperature.

The saturated steam produced in the heat recovery boiler is superheated prior to entry into a steam turbine generator which makes electricity. Superheating occurs in a superheater. A superheater is another heat exchanger, which cools gas after catalyst bed 1 ( Chapter 9) and superheats that steam for power generation.

Almost all modern boilers already have some sort of heat recovery built in, making condensing boilers much more efficient than older ones. Even so, FGHRS can further increase the efficiency of these condensing boilers in most cases, delivering the same amount of heat with up to 4% less gas. The Ideal Logic Code Combi ESP1 has a built in FGHRS.

Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.

The exhaust gas heat exchanger uses the waste heat generated during energy generation in the form of flue gases. To make effective use of the available heating power, the residual heat of this exhaust gas is used to add it to a second medium – for example the heating water. In this way, the existing residual heat can be significantly reduced by using it for recovery.
