  • 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 (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Learn More

    Alternative water-tube boiler layouts. The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).Learn More

  • Boiler Questions and Answers regarding Your Boiler

    Our 1,200,000 lb/hr steam boiler normally operates at around 3% excess O2 or 15% excess Air. If it operated at 3% excess O2 what would be the approximate % boiler efficiency loss? Answer. The term Boiler efficiency is a generic term that could mean many things. The best definition of your boiler's efficiency is the fuel-to-steam efficiency.Learn More

    Lancashire Boiler is a horizontal type and stationary fire tube boiler. This boiler was invented in the year 1844, by William Fairbairn. This is an internally fired boiler because the furnace uses to present inside the boiler. This boiler generates low-pressure steam and it is a natural circulation boiler.Learn More

  • How Power Plant Boiler Works? - Bright Hub Engineering

    Jan 27, 2009 · These are a set of coils made from steel tubes located in the tail end of a boiler. The hot gases leaving the boiler furnace heat the water in the coils. The water temperature is slightly less than the saturation temperature. From the economiser the water is fed to the 'drum'. Pre-Heating & Economiser Latent Heat Addition. Drum.Learn More

  • Boiler Classification and Application - CED Engineering

    The heat from the burner is transferred to the water tubes. As water flows through the tubes, the combustion gases heat the water and produce steam. This steam is collected in the upper drum, while combustion gases exit the boiler stack as flue gas. Several types of tubes are found inside the boiler.Learn More

  • Foaming and priming in boilers - Lenntech

    Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of Learn More
