The combustion of natural gas produces CO 2 and water vapour through reactions between oxygen (O 2) and gas carbon (C) and hydrogen (H). The latent energy content in water vapour in the flue gas represents an equivalent to the energy required to bring the volume of water from liquid to vapour form.
Oxygen attack in boilers - Lenntech
The mechanical degasification is typically carried out with vacuum degasifiers that reduce oxygen levels to less than 0.5-1.0 mg/L or with deaerating heaters that reduce oxygen concentration to the range of 0.005-0.010 mg/L. Even this small amount of oxygen is corrosive at
Electric Boiler vs Gas Boiler: Pros, Cons & Running Costs
At 60°F and atmospheric pressure, the solubility of oxygen in water is approximately 8 ppm. Efficient mechanical deaeration reduces dissolved oxygen to 7 ppb or less. For complete protection from oxygen corrosion, a chemical scavenger is required following mechanical deaeration.

Natural Gas Boiler - an overview | ScienceDirect Topics
It is a natural gas boiler that produces hot water for domestic use and electricity A Stirling double-acting engine is coupled to an alternator. The WhisperGen unit has been studied by several researchers such as Cacabelos et al. who propose a dynamic model of the commercial microcogeneration unit.
