Jul 27, 2016 · Different types of boiler (steam). The boilers are used in power plants for the generation of steam. They are crucial for the working of a power plant. They are mostly used in the power plants where steam turbines are used for the generation of electricity. The knowledge of boiler is very essential if you are a mechanical engineer.
Coil Type Boiler : Revosteam. Revosteam,coil type boiler, is a unique water tube coil type boiler in which water flows inside the tube. Revosteam is mostly oil-fired or gas fired boilers which include burner assembly to fire oil or gas. It incorporates the unique principle of combustion known as “Reverse Flow”.
I. Basic Boiler Types There are two basic boiler styles for steam boilers in this range, Firetube and Watertube boilers. As their names imply, the Firetube boiler has the fire (combustion gases) inside the tube and the Watertube boiler has the water inside the tube. This allows for large variations
1. Boiler Types Typical boiler types are defined, including: firetube, firebox, industrial watertube, and commercial watertube boilers. General information is provided on the differences in boiler types (sizes, ranges, pressures, etc.). For more detailed information on boiler products, refer to the specific boiler product section. 2. Boiler Selection
Coil-type steam generators provide an average of six Btu per sq ft per F, which translates to a heating surface requirement of approximately 1.67 sq ft to produce one boiler horsepower (bhp). The result is a relatively small footprint for the coil-type steam gener-or physical access (or perhaps all three) are limited or restricted.
