    Boiler House Surveys

    By law, steam boilers in the UK need to be regularly maintained to help ensure safe and efficient operation.

    An important part of the maintenance routine is regular blowdown of the boiler water which helps maintain the water quality in the boiler and the system overall, of which there are three main types: bottom blowdown, TDS blowdown and level gauge blowdown.

    Valveforce offers peace of mind by ensuring that your steam boiler plant is compliant with all regulatory standards, including the CEA’s BG03 and necessary HSE guidelines, and ensures that your bottom blowdown works efficiently and effectively.

    You can also rely on our team of steam solutions experts to offer advice and undertake complete boiler house and boiler surveys.

    In the boiler house we:

    • investigate boiler feed water conditioning
    • to supply boiler feedwater tank and deaerator plant equipment and accessories
    • provide water treatment equipment, including water softening and reverse osmosis (RO) plant

    For the steam boiler we:

    • review boiler control equipment for level control
    • check boiler blowdown
    • test boiler heat recovery equipment

    From the boiler house surveys, Valveforce produce detailed reports to ensure that your boiler blowdown valve and boiler house are up to date and in keeping with the latest standards and legislation.

    If you would like further information and advice, please contact Valveforce on 0121 711 1908 and ask for the boilerhouse specialist team.

    Boiler Blowdown Systems Services

    Bottom Blowdown

    • Carried out by the bottom blowdown valve on the bottom blowdown line
    • Required to remove sludge and sediment deposits at the bottom of the boiler
    • Sludge build-up can cause potentially dangerous damage to boiler tubes
    • 3-5 second purge of the bottom of the boiler
    • Required daily or per shift
    • Automated or manual depending on site preferences.

    Level Gauge Blowdown

    • Level gauges on the side of the boiler are drained regularly to avoid dirt build up
    • Scale and dirt build up impairs proper reading of gauge glasses resulting in potentially dangerous misreading of the boiler level
    • Carried out manually by drain cocks at the bottom of the gauges
    • Required to be carried out regularly by law on boiler arrangements

    TDS Blowdown

    • Continuously blowdown via an electric TDS valve
    • Required to keep Total Dissolved Solids in the boiler water to within prescribed levels (approx. 2000 ppm for small industrial shell boilers and 3500 ppm for larger boilers)
    • Excess TDS levels leads to carry over and poor water level quality
    • View our page on Boiler TDS Systems here

    The Blowdown Vessel

    • As these types of blowdown are at boiler temperature and sending these blowdowns straight to drain is a Legionella risk, a blowdown vessel is required to receive the blowdowns. This allows the hot discharged water to cool before being sent to drain.

      Valveforce follow the CEA’s latest guidance on Boiler Maintenance (BG01 – Guidance on Safe Operation of Steam Boilers) and Blowdown Systems (BG03 - Blowdown Systems Guidance for Industrial Steam Boilers) when advising customers on blowdown design and new equipment.
