Natural Gas Heating Systems - Mass Save

Gas Boilers. Condensing boilers are gas-fired boilers that achieve efficiency by condensing water vapor in exhaust gases and recovering latent heat that would normally be lost up the flue. By doing so, they can achieve efficiency of 90 percent or higher, but this is only true if

Oil-Fired Boilers and Furnaces | Department of Energy

An aquastat controls the temperature of the hot water in a boiler, typically keeping it around 180°F. But when heating needs are lighter in the spring and fall, that's actually higher than needed, and wastes energy. A modulating aquastat, also called an outdoor reset, senses outdoor temperatures and adjusts the hot water temperature accordingly.

Using cold boiler feed water for energy recovery

Boiler feed water to a gas turbine HRSG is provided from the same header to the oil-fired util-ity boilers. The water temperature is kept above 140°C to prevent sulphuric acid corro-sion in the boiler economisers. However, only natural gas is fired in the gas turbine and there is no risk of sulphuric acid corro-sion in the HRSG, so cold water
