What Is A Condensing Boiler? | Boiler Advice | Vaillant UK

A condensing boiler uses condensing technology to make better use of the heat it generates. When a fuel such as gas or oil is burned, gasses are released via a flue. In a non-condensing boiler system these gasses would be released into the atmosphere and their heating potential would be lost. However, in a condensing boiler the hot gasses are

Vitoflex 300-RF Commercial Wood-fired Boiler | …

With its patented rotary combustion chamber design, the Vitoflex 300-RF boiler features the industry's most advanced combustion technology. A feed auger continuously moves the wood fuel onto a moving grate, where gasification of the fuel under precisely controlled primary air takes place. The combustible gases (syngas) then rise into the rotary

Field-tube boiler - Wikipedia

Field-tube boiler. A Field-tube boiler (also known as a bayonet tube ) is a form of water-tube boiler where the water tubes are single-ended. The tubes are closed at one end, and they contain a concentric inner tube. Flow is thus separated into the colder inner flow down the tube and the heated flow upwards through the outer sleeve.

Water Handbook - Preboiler & Industrial Boiler Corrosion …

The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding device (speed variator of coal feeder) directly.
