  • Benefits of low-temperature heating systems - HeatGeek

    Nov 01, 2018 · Boiler efficiency is typically calculated based on fuel composition, firing conditions and 'stack losses'. Stack losses are represented by any heat that leaves the boiler via the flue. There are two types of stack losses, 'Dry flue gas losses' and 'Flue gas loss due to moisture'. When measuring dry flue gases you are measuring 'sensible heat' loss.Learn More

    Jan 09, 2020 · Flue gas temperatures on natural draft boilers (taken before the draft hood) should be 390ºf to 570ºf, if the unit is tuned properly by combustion analysis. This is based on water temperatures of 120ºf to 200ºf plus 270ºf to 370ºf. Instead of learning the tricks of the trade, learn the trade. Liming20, 02:02 PM #10.Learn More

  • Flue gas temperature or flue gas loss | Bosch steam boiler

    The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.Learn More
