  • How does ZG water tube boiler work?

    27/11/2013 · ZG water tube boiler working principle. The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum.In some services, the steam will reenter the furnace through a superheater to become superheated.Superheated steam is defined as steam that is heated above the boiling point at a given pressure.

    2/9/2014 · Saturated (not superheated) steam at 1310 PSIG is 5% the density of 100°F water. For example, if a drum were full of 580°F water up to the top tap 50" above a bottom tap, it would register over 13" of DP, instead of the 0" DP it would read if the densities were the same. If the water is at the operating level 18" above the lower tap, the

    Double drum boiler. Double drum boiler can also be divided into vertical boiler and horizontal boiler. For the longitudinal double drum boiler, it is not only SZL of double boiler chain boiler, but also the SZS model of oil gas fired boiler. In contrast, the double cylinder vertical type is usually the most common one.

  • Advanced control for boiler drum level?

    18/11/2015 · Drum level is only one control loop of a typical boiler. Feed-forward control is often used for boilers where there is a wide range of varying demand and where the feedwater is returned at varying temperatures, as from steam condensate. Feed-forward control is designed to remove the effects of load variables as they make their way to the boiler

    1/1/2016 · Conversely, as steam demand increases, drum pressure decreases, and the gas bubbles expand, often causing the drum level to appear to increase. To help compensate for shrink and swell, boiler control engineers employ three-element control strategies that simultaneously look at steam flow, the rate feedwater is flowing to the steam drum and the water level in the steam drum.

    30/5/2018 · Boiler Steam drum internals and function. In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes.
