Furnaces and Boilers | Department of Energy

Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler Efficiency - engineeringtoolbox.com

Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the

Peerless Boiler vs. Burnham Boiler: Which Is The Best

Jan 21, 2020 · An energy-efficient boiler can reduce energy consumption and lower home heating costs. The main thing to check is the annual fuel utilization efficiency or AFUE rating. Invest in a high-efficiency unit, and you will save on fuel without sacrificing comfort.

Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

Boiler Efficiency - an overview | ScienceDirect Topics

The fuel savings as can be seen from the figure can be substantial depending on the boiler operating time. As expected the longer the boiler stands-by the larger are the fuel savings. Thus a boiler operating for 12 hours, firing typically for about one-third of a cycle has a fuel saving of 5.5% compared to 1.7% for 24 hours operation.

Condensing boiler - Wikipedia

Doing so would reduce fuel consumption considerably, but would quickly destroy any mild steel or cast-iron components of a conventional high-temperature boiler due to the corrosive nature of the condensate. For this reason, most condensing boiler heat-exchangers are made from stainless steel or aluminum/silicon alloy.
