    to flow through the pipes. The steam generated in the boiler must be conveyed through pipework to the point where its heat energy is required. Initially there will be one or more main pipes, or 'steam mains', which carry steam from the boiler in the general direction of the steam using plant.Learn More

  • Boiler Ratings | Spirax Sarco

    Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam …Learn More

  • Water Handbook - Steam Purity | SUEZ

    In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.Learn More

  • QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

    Chelating agents offer an opportunity for supplying better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele,Learn More

    Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.Learn More
