How to calculate the gas consumption of a gas steam boiler ...

Jun 24 2019 · The condensing gas steam boiler produced by Fangkuai uses a advanced condensation technology to set up a condensing recovery device near the flue. When the high-temperature flue gas passes through the device the latent heat part encounters the condensed water to release heat which is supplied to the boiler for absorption again.

How Much Gas Does Your Boiler Consume? | 128 Plumbing

Condensing gas boilers have a much higher AFUE than non-condensing boilers ranging from 88% to around 92% for the most efficient gas boilers. Condensing boilers utilize wasted energy by extracting the latent heat from the condensed water vapor produced during the gas combustion process inside the boiler. By contrast many older boilers have an ...

The Definitive Guide to Condensing Water Heaters or Boilers

So if on leaving a boiler the flue gases are cool and the water is liquid then the amount of energy E that we can use is going to be larger. In a condensing boiler the water is condensed inside the boiler so more energy can be extracted; in a conventional boiler the

Steam and Condensate - What is Condensate?

Steam that has been condensed back into water by either raising its pressure or lowering its temperature. Not to be confused with demineralized de-ionized make up or softened water. When the condensate enters the boiler feed pump additional chemicals are added and the product is now called boiler feed water.
