The stack temperature of 3 pass will be lower than that of 2 pass boiler, of the same design and operating pressure. Efficiency is more than two pass boiler. Each pass in boiler should be designed with cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing sooth build up within the tubes.

The circulation of air is caused by a difference in pressure, known as draught. Thus the draught is the difference in pressure between the two points i.e., atmosphere and inside the boiler. It is measured in mm of water. A differential in draught is required to cause flow of air or gas through the boiler setting.
