Boiler (power generation) - Wikipedia

The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,3001,600 °C (2,3722,912 °F ). Some superheaters are radiant type (absorb heat by thermal radiation ), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.

Chapter 30 - Once-Through Cooling | SUEZ

In untreated once-through cooling systems, the metal loss may reach 100 mils (0.1 in.) per year. Treatment typically reduces the corrosion to 10 mils (0.01 in.) or less per year. In addition to metal loss, deposit problems are caused by corrosion product accumulation in a heat exchanger tube exposed to an untreated stream of cooling water.

Design of Once through Boiler | Steam Power Plants

5. A once through boiler is smaller in size and weighs less in comparison to a natural circulation boiler. 6. Easy control of steam temperature during start-up and shut down (which is very advantageous for start-up of boiler and turbine). 7. Greater freedom in arrangement and location of heating surfaces.

Explain the working of a once through boiler with the help

The once through boilers do not have any boiler drum as there will be no formation of water+ steam mixture available for separation. Instead of the drum, these boilers employ separating vessels. The feed water fed to the boiler is preheated using regeneration to raise the feed water temperature and harness the heat of the extraction steam.

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.

Once-Through Boilers | Boilers - Product Lineup

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions. Mitsubishi Hitachi Power Systems (MHPS) delivered its first supercritical pressure once-through boiler

Water tube boiler. This type of boiler is generally preferred in high pressure applications since the high pressure water/steam is contained within narrow pipes which can contain the pressure with a thinner wall. It can however be susceptible to damage by vibration in surface transport appliances.
