  • Steam Generator vs. Steam Boiler | Powerhouse

    If you are searching for a steam energy solution for your business, you likely have come across the confusing differentiation between a steam generator and a steam boiler. The most basic understanding of these two systems is that they both produce energy through steam, however, they accomplish this in fundamentally different ways.

    Boiler, also called Steam Generator, apparatus designed to convert a liquid to vapour. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect. A conventional boiler has a furnace that burns a

  • Steam generator

    The steam which drives the steam turbine is generated by heating water. In a nuclear power plant, the conventional steam boiler is replaced by a steam generator . This is a heat exchanger in which two water circuits meet each other: hot water under extremely high pressure in the primary circuit leaves the reactor and flows through thousands of U-shaped heat conducting tubes.
