What is a condensing boiler? A condensing boiler runs on gas or oil and has been designed to help improve energy efficiency. This is done by converting water vapor condensation into heat; they're able to recover some of the lost heat from waste gases. The only difference between a condensing boiler and a non-condensing boiler is the amount of Get Price
Acid attacks can happen from chemicals other than carbon dioxide. In high-pressure boilers, soluble nickel or magnesium salts can hydrolyze into acids. These acids attack the surfaces inside the boiler, leading to further pitting and corrosion. 3. Dissolved Solids. Solids in the water may also contribute to corrosion formation.Get Price
There are 2 types of economizers: non-condensing and condensing. Non-condensing economizers. The most common are non-condensing economizers. They are heat exchanger coils‚ usually finned‚ that are located in the flue gas ducting at the exit of the boiler. Typically‚ a non-condensing economizer will raise the overall efficiency by 2% to 4% Get Price

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.Get Price
