    The Clayton Back Pressure Regulator is designed to:

    • Provide stable operation of any steam generator where steam loads fluctuate rapidly or periods of sudden overload occur.

    • Provide stable operation on start-up and during operation ofmultiple steam generator installations. Enables the steam generating equipment to re­ main in balance, thus reaching operat­ ing pressure more rapidly

    • Provide high pressure steam more

    rapidly when used on heavy oil burn­ ing units equipped with steam/electric fuel oil heaters, thus reducing the cost of electrical pre-heat.

    By controlling the minimum pressure of the steam generator the Back Pres­ sure Regulator prevents "flashing" of the liquid in the steam generator, thus maintaining it in a stable condition at all times. This results in a faster heat up of the steam system after initial start and faster recovery after an overload period. The pressure differential held by the regulatorwill notretard heat de­ livery to the system.

    INSTALLATION On multiple installations, a separate regulator is required on each steam generator. The regulator must be installed vertically (as shown) with the steam outlet at the top.

    ADJUSTMENT After installation, the regulator is adjusted in the fo llowing manner: From an initial start on a cold system, operate the steam generator at full fire. While the plant system pressure is still zero or low. immediately adjust the spring on the regulator to give the proper separator pressure as required for maximum adjusted working pressure. These pressures are:

    Steam System Adjust Back Pressure

    Maximum Regulator to Retain

    Working Pressure Separator Pressure

    350 psig 290 psig

    300 psig 240 psig

    200 psig 160 psig

    150 psig 110 psig

    100 psig 70 psig

    For immediate working pressures, adjust the regu lator to approximately 80% of the OUT•

    maximum working pressure. Example: For a maximum adjusted working pressure 1 8i of 190 ps i, the regulator should be adjusted to a separator pressure of 150 psi. These rr- iA . ­ settings will result in a minimum pressure drop across the regulator of approx­ IN ,L - -1­ imately 5 psi at full working pressure.
