Although high-mass boilers are capable of handling higher ΔTs without damaging the pressure vessel, the 30°F to 50°F (17°C to

This is the temperature at which water droplets form. For natural gas boilers, the dew point is around 55C. In other words, the water in the return pipe needs to be 55C or lower or your boiler

Temperature inside boiler (furnace) is around 1100 deg to 1200 deg. Although it is favorable to keep it under 1100 deg or otherwise ash in flue gas will melt as forming clinkers and it will stick to to boiler walls. I am talking about big boilers

Firetube boilers tend to leak at the tube inlets and this problem occurs in waste heat boilers also. Tube size is a compromise between the conflicting requirements for low velocity at the high temperature inlet and high velocity at the low temperature outlet.

Plus, being able to maintain the higher flow temperature is useful for hot water heating. For example, with a flow temperature of 80°C and return temperature of 50°C using natural gas, the boilers have the opportunity to condense whilst being able to provide the required higher temperature water for driving a calorifier or plate heat

managing condensate for condensing boilers

Managing Condensate for Condensing Boilers

Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less. It is this resulting condensate liquid that is acidic and requires treatment to avoid damage to piping systems, sewerage systems and other items it may come in contact with.

Stephen M. Hall PE, in Rules of Thumb for Chemical Engineers (Sixth Edition), 2018. Introduction. Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high-pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the
