The chemical treatment is used to reduce the amounts of chemicals such as CaPO 3 , Fe 2 O 3, CaCO 3, CaSO 4, and silicates that can cause build up in the heat transfer equipment and reduce performance as shown by Figure 2. The economizer is used to preheat the water entering the boiler with the flue gas.

5/5(2) Two pass boilers: In two pass the combustion gases travels two times in the boiler. Combustion gases should be cooled before entering the reversal chamber. Excess temperature causes overheating and cracking of the tube. The heat transfer rate is maximum at the first pass, this rate decreases with the increasing passes. Three pass boilers: A three pass design provides three opportunities for heat transfer.

Single Pass Boilers Vs. Triple Pass Boilers - Marbleda

Apr 17, 2015·  A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel.  The design extracts heat from three times as much interior surface area of the boiler, compared to a single-pass, “pin-type” boiler design. Buderus boilersprovided this great example illustrating the efficiency of 3-pass boilers:
