    Alloy Customized Heat Recovery Steam Generator For Power Plant With ASME Standard


    Alloy Customized Heat Recovery Steam Generator for Power Plant with ASME Standard

    Product Introduction


    HRSG are a type of Waste Heat Recovery unit which uses waste heat (generally from Gas Turbines) to generate steam. Therefore, HRSGs are generally attached to the exhaust of Gas Turbines. They are commonly used in Combined Cycle Power Plants where both Gas and Steam turbines are used to drive generators. Common parts of a heat recovery steam generator include the following:


    Superheater and desuperheater
    Steam drum, mud drum, drum internals
    Tubes
    Duct Burner for supplemental firing
    Blow down tank
    Economizer
    Firing equipment including duct burner, burner management system, pilot burner
    Bypass stack and exhaust stack, sealing air fan,baffles, piping, valves and controls


    Features

    Kiln (AQC) HRSG Features

    1, Modular assembly structure, reliable sealing expansion

    2, Adopt wear fin tubes, boiler pressure parts life assurance

    3, Unique flash technology, the boiler outlet temperature is reduced to below 90ºC


    Kiln (SP) HRSG Features

    1, Heating surface tubes and headers with privildged connection structure, reducing mechanical shock and vibration

    2, By mechanical vibration cleaning mode, continous cleaning mode little impact on system operation

    3, Set sealed scraper gray machine, greatly reducing dust tail.


    Attention

    • The design and construction of HRSG should be such that no detrimental vibration of tubes, piping, casing, transition ductwork and exhaust stack is present under any operating condition.
    • All components of HRSG system should be capable of being completely drained. Low point drains should be provided for all enclosures, ducts, piping, and coil assemblies. All drain connections provided on coil assemblies should be piped together to provide a single collection point.
    • Supplementary firing should be adopted as required and can be achieved by duct burners.
    • If designed and constructed to ASME BPVC, the manufacturer should obtain material certificates for all components, and all required code stamps and certificates .
    • Superheater elements should be located and supported to prevent vibration, sagging and misalignment
    • For greater efficiency economizers should generally be furnished as part of an HRSG.
