The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost.

Air Supply Bulb In Steam Boiler - gruppomontemagno.it

We can see exactly how this works by going back to the psychrometric chart and pretending that we have a steam humidifier in place that will add water vapor to the supply air. It takes energy to convert water to steam, so any type of steam humidification requires an outside energy source like electricity, natural gas, or a steam boiler. Learn More

The operating logic within this controller gives priority to maintaining the boiler inlet temperature above a user-selected minimum value, which, in the example in Figure 4, is 130°. The system in Figure 4 uses a mixing valve controller that measures boiler inlet temperature. Notice that the water temperature entering the boiler is now 130°.
