What Are The Accessory Equipment Of 10 Ton Steam Boiler Vijayawada
Mar 05, 2020 · A condensing boiler is a form of gas boiler that can work at a higher efficiency. Non-condensing gas boilers could lose up to 40% of the heat they generated via the flue, whereas condensing boilers can recover most of that heat by capturing it before it leaves the flue and re-cycling it to pre-heat the boiler.

Modulating condensing boilers (mod-con boilers) can increase combustion efficiency to about 96%, up from the 80% efficiency of non-condensing boilers. They provide a range of firing rates to match the variable heating load of the building. However, mod-con boiler efficiency depends on the temperature of the water returning to the boiler.

Aug 13, 2018 · The biggest difference between condensing boilers and "conventional", non-condensing boilers is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation.
