Fired tube boilers consist of a series of straight tubes that are housed inside a water-filled outer shell.
The tubes are arranged so that hot combustion gases flow through the tubes.
As the hot gases flow through the tubes, they heat the water surrounding the tubes.
The water is confined by the outer shell of boiler..
Boiler design is the process of designing boilers used for various purposes.
The main function of a boiler is to heat water to generate steam.
Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation..
The Main Components of a Boiler
The three main components of all boilers are the burner, combustion chamber and heat exchanger..
The function of a boiler is to either produce hot water or steam.
Hot water boilers heat water for the purpose of domestic or commercial heating and hot water supply.
Steam boilers generate steam in order to power turbines for power generation and various other industrial heating applications..
Boilers heat water, and provide either hot water or steam for heating.
Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil..
Industry: boilers are used for power generation, process heat (e.g., refineries, petrochemicals, paper mills, tire manufacturing, etc.) and heating.
In buildings, boilers are used for steam primary heat, terminal reheat systems, water heating and absorption chillers..
Some of the most frequently used steels for boiler tubes include low-alloy steels containing alloying elements such as chromium, nickel, molybdenum, and vanadium, 9–12% chromium steels, austenitic stainless steels, austenitic heat-resisting steels, and nickel-base heat-resisting alloys..
