Technical advice on boiler combustion control - reliableplant.c

Energy can be recovered from exhaust gases by transferring thermal energy from the high-temperature gases to boiler feedwater, or to the combustion air entering the boiler. Another aspect of exhaust-gas energy management, which is the focus here, is combustion management.

Replacement Gas Boilers - Energy Dep

Many older boilers have AFUE ratings of only 55-65%. If your boiler has not been well maintained, then its efficiency may be even lower. The current minimum AFUE for a new fossil-fueled hot water boiler is 80%, and the minimum rating for a gas-fired steam boiler is 75%. New high-efficiency boilers can have AFUE ratings of 90% or higher.

Back to Basics: Venting for Gas-Fired Boilers | 2003-06-04 .

The rating plate contains basic information about the boiler, such as the manufacturer, model number, input and the vent category. All gas-fired, low pressure steam and hot water boilers certified to the ANSI Z21.13 standard are required to have the vent system category (I, II, III or IV) on the rating plate.

Why Oxygen Levels Matter in High Efficiency Boile

For every pound of water vapor condensed there is approximately 1,000 BTU's of latent energy. Condensing extracts that latent energy from the combustion exhaust gas and heats the water with it, increasing overall boiler efficiency. High efficiency boilers require combustion gas calibration at start up.
