  • List of boiler types, by manufacturer - Wikipedia

    2019-10-19 · Ramzin boiler or 'straight-through boiler': a once-through monotube boiler with a water-wall furnace. It was distinguished from similar boilers, such as the Benson, by its use of near-horizontal tubes in a shallow helix. It was invented by the Russian Leonid Ramzin, whilst imprisoned in a sharashka.

    2004-3-19 · Package Boiler All but the largest boilers used for heating and industrial purposes are packaged boilers. They are factory-built and shipped whole or in modular components to the customer. Many are constructed in an elongated shape that will fit through large building doors with minimal field adjustment required.

    Relying on a single large boiler can have a number of problems in terms of efficiency, cost, and the environment. MIURA's Multiple Installation System connects multiple units of small-sized one-through boilers. This requires less water while eliminating the problems of traditional large-sized boilers.

    2014-4-10 · For the operation of the supercritical once-through boiler generation units, the control of the temperature at intermediate point (IPT) is highly significant. IPT is the steam temperature at the outlet of the separator. Currently, PID control algorithms are widely adopted for the IPT control. However, PID cannot achieve the optimal performances as the units’ dynamic characteristic

  • What is meant by once through a boiler? - Quora

    Traditionally boilers circulate water within them and only a portion gets turned into steam on any one pass. Circulation ratios (the amount of water recirculated versus the amount taken out as steam) can vary from 3 to 20. This serves several purp

    Abstract: A large-scale once-through-type ultrasupercritical boiler power plant is investigated for the development of an analyzable model for use in developing an intelligent control system. Using data from the power plant, a model is realized using dynamically recurrent neural networks (NN). This requires the partitioning of multiple subsystems, which are each represented by an individual NN
