The Economizer: What, Why, and How? - Boiler Blog
In a boiler system, an economizer captures the heat of the flue gas and transfers it to the feed water. The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler feed water, lowering the needed energy input.

Water tube boilers can have pressures from 7 bar (one bar = ~15 psi) to as high as 250 bar. The steam temperature's can vary between saturated steam, 100 degrees Celsius steam with particle of water, or be as high as 600 - 650 degrees Celsius, know as superheated steam or dry steam (all water particle have been turn to a gaseous state).

Function of condenser in a feed system for boiler and
Function of condenser in a feed system for boiler and steam turbine ; The condenser is a heat exchanger which removes the latent heat from exhaust steam so that it condenses and can be pumped back into the boiler. The feed system completes the cycle between boiler and turbine to enable the exhausted steam to return to the boiler as feedwater.

Boiler Combustion Air Flow Measurement | Yokogawa America
On many boilers, air flow is the measured differential between the furnace inlet and the boiler outlet. This takes the differential of the hot gases as they flow through the furnace, across the convection section, and out the stack. In most cases, the differential ranges from 0.5 to 2.0 inches of water.

For this reason all gas/air tube or regenerative type heaters have a low load by pass arrangement. For water tube boilers gas air heaters are only considered where the temperature at inlet to economiser is greater than 200 o C. Due to greater heat transfer efficiency between gas/water economisers are preferred to gas/air exchangers.
