Single, double or triple pass cooling - what's the .

Here we discuss the importance of single, double and triple pass cooling. Every shell and tube heat exchanger carries a flow of cooling water through its central tube core. But depending on its design, the water may flow through the unit once, twice or three times, which is done to get the optimum cooling performance for the available volume of ...

AFUE - Single Pass vs Triple Pass Boiler.... ? — Heating .

Flame temperature and flame exposure (size and distance)from heat exchanger. You lose up to 50% of radiant transfer with a small flame. A three pass boiler should always be more efficient than a single pass but anything can be misfired to create a high AFUE. AFUE does not address delivered efficiency just tampered with burner operation.

Tower Types and Two Pass Boilers - Bright Hub Engineeri

The main advantage of the tower type is they can accept more erosive high ash coals. However when any pressure part failure happens in the horizontal sections then it is much more difficult to attend when compared to the two pass design. Both the school of thoughts is present with the boiler designers regarding the advantage of tower type and two pass design of boilers.

The stack temperature of a 4-pass boiler will be lower than the stack temperature of a similar size 2- or 3-pass boiler operating under similar conditions. The 4-pass will have higher efficiencies and lower fuel costs. This is not an opinion. It is basic heat exchanger physics. The 4-pass design yields higher heat-transfer coefficients.
