High Pressure Boilers: Meaning, Types, Characteristics

It is a high pressure, water tube, forced circulation boiler. It has unique characteristic of absence of drum and entire process of heating, steam formation and superheating takes place in a single continuous tube. Working: Feed water pump feeds water to the economiser, from where it goes to the radiant heating section.

Boiler 101 | What is a boiler? - Home | American Boiler

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.

Boiler - an overview | ScienceDirect Topics

Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high-pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the tubes with the water being in the shell (fire

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.

Comparison Between Fire Tube and Water Tube Boiler

Jun 05, 2018 · In Water-tube boilers water passes through tubes and hot flue gasses surround them. These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers. The rate of steam generation and quality of steam are very low, therefore,

as the position of the water and hot gases. In a fire tube boiler, hot gases are inside the tube and water is at outside the tube, while water tube boiler has water inside the tube and gases on the outside. Fire tube boilers produce lower rate of steam compared to water tube boilers. The focus for this will be on HRSG with water tube boilers.
