  • Area of Ellipsoidal Heads - Boiler and Pressure Vessel

    Jan 30, 2004 · I was going to give you a head blank size which would have worked, but on the conservative side. For a 1.875" thick head The head blank prior to forming for a 144" OD head is 188". The head blank prior to forming for a 72" OD head is 99" It works out that your head blank should have been between 198" and 200" Dia.Get Price

  • Three-drum boiler - Wikipedia

    Excess steam production at the rear of the steam drum led to disrupted circulation and a problem with priming. The development of water-walls for this type of boiler was abandoned, although trials did continue with HMS Hyperion (H97) which was trialled with a single water-wall Johnson boiler replacing one of its three three-drum boilers.Get Price

  • Boiler Efficiency - an overview | ScienceDirect Topics

    P. GoldsWorthy, E. On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.Get Price
