# ﻿Natural Gas Boiler Effeciency

• ### Industrial Boiler Efficiency Calculation & Factors | …

If this energy can be captured and reused in the boiler process, the boiler efficiency can be increased. Given that 12 weight percent of the flue gas is water, at 15 percent excess air, a significant energy savings can be achieved through the recovery and use of this latent heat. When the water vapor is condensed, the latent heat is recovered at 980 Btu per pound and each pound will save one cubic foot of natural gas.

• ### How efficient is my boiler? - British Gas

The thermal efficiency of a condensing boiler is dependent on its heating flow and return temperatures. Condensing boilers are designed to positively encourage condensing of the flue gasses and in order for this to occur, the return water entering the condensing boiler from the heating circuit has to be below the dew point of flue gases (55°C), ideally below 52°C4.

• ### Combustion Efficiency and Excess Air

The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Typical excess air to achieve the highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil.

5/4/2018 · In other words, natural gas (methane) is to gas fossil fuels what lignite is to coal. But, for the 50 years prior to 2008, natural gas was always more expensive, considerably, than fuel oil. Only with advancements in hydrofracking technology and massive drilling efforts through the Mountain West and Desert Southwest since 2005 did that change.

• ### Boiler Efficiency and Combustion | Spirax Sarco

Fuel specification plays an important part in boiler efficiency. In the case with gaseous fuels, the higher the hydrogen content, the more water vapor is formed during combustion, resulting in high water vapor losses and a lower efficiency. This is why oil fires operate at higher efficiency levels than natural gas.
