  • boiler safety and role of low water levels

    Boiler Safety and Role of Low Water Levels

    Hence, a Low-water condition has the potential to melt the steel tubes. Controlling the boiler drum level is complicated as the "water level" in a steam drum is actually a fairly unstable mixture of water and steam bubbles that shrinks and swells as the pressure changes. This is because of the fact that as the steam demand increases, the

    Top Ten Boiler and Combustion Safety Issues to Avoid

    One is the boiler /machinery (B/M) coverage for the pressure side, meaning the tubes, drums, water level controls and safety relief valves. The second part of a boiler’s insurance is the property coverage, which covers the fire side, such as the fuel train, firebox, and refractory-related issues.

    Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition. The water level in a steam drum is actually a fairly unstable compressible mixture of water and steam bubbles that shrink and swell with pressure changes, firing rate changes, and when colder feedwater is added.

    Methods of Detecting Water Level in Steam Boilers | Spirax

    Low water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does not continue if the water level in the boiler has dropped to, or below a predetermined level. For automatically controlled steam boilers, national standards usually call for two independent low level alarms, to ensure safety.

    Low water cutoff valves shut off the boiler if the water level drops too low. Checking the operation of these should be a part of the job of someone in the building. Drain the tank for a few seconds to test the float chamber whenever it’s not in a firing sequence. The low water control system should kick in …

    Level probes can be arranged to signal high water level, the normal working (or control) water level, and low water level. The signals from the probe can be linked to a control valve on the cold water make-up supply. The probe is fitted with a protection tube inside the feedtank to protect it from turbulence, which can result in false readings.

    Fig. 3.4 depicts the generic layout of a water cooled condenser where the cold water flows in the tubes and the vapor in the shell. The vapor enters from the top, hits an impingement plate and it is distributed on the whole tube bundle. Vapor comes into contact with the cold tubes, it condensates and it is eventually subcooled.

    The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F.

    Lower Pressure Operation of Boiler than Designed

    In constant pressure operation the boiler superheater outlet pressure is designed to be maintained constant from as low as 40% of the rated maximum continuous load. In sliding pressure boilers the superheater steam outlet pressure is slowly taken up at a particular ramping rate acceptable to both boiler and turbine designers.
