Condensing boiler with an indirect DHW system and outdoor reset control . Condensing boilers achieve high efficiencies because they can recapture the latent energy from the moisture in the combustion gases when those gases condense. For condensing to occur, the boiler’s heat exchanger surface temperature must be below the flue gas dew point.

Oct 14, 2014· It is the point at which the boiler uses all of its bag of tricks to keep itself in 'condensing mode' (modulating the flame and keeping the outgoing temperature at a level which keeps the return low enough for that 10% efficiency boost) for that 95% of the time.

The diverse steam boiler selection at Grainger includes high-efficiency wall-mounted condensing boilers, cast iron compact gas-fired boilers and direct-spark boilers with Energy Star ratings.

Aug 13, 2018· Condensing boilers produce heat by burning natural gas or propane fuel. The word “condensing” refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler. The temperature of these flue gases

In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155.

Author: Tim Cremin Jan 22, 2020· For the condensing boiler to operate at maximum efficiency, the secondary heat exchanger’s surface needs to be equal to or below the dew point temperature of …

Heat is removed from the flue gas through the use of economizers and air preheaters, but condensing water (and acid gas) is a limitation in how low the temperature can be taken. Condensing flue

The exact pump type required for the project may require specific information about the system; however, as a general rule, here are some: If the steam pressure to the heat exchanger is less than 10 PSIG, use a Bell & Gossett Domestic Series CC condensate unit rated …

Condensing vs. Non-Condensing All boilers are either condensing or non-condensing. A condensing boiler concentrates water vapor produced in the heating process, and uses waste heat to preheat cold
