Dynamic Shrink/Swell and Boiler Level Control – Control Guru

Conventional shell boilers are normally operated with the TDS in the range of 2 000 ppm for very small boilers, and up to 3 500 ppm for larger boilers, provided the: Boiler is operating near to its design pressure. Steam load conditions are not too severe. Other boiler water conditions are correctly controlled.

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.

17/9/2013 · I checked some Steam Turbine generator (STG) and Boiler vendor's hook-ups but they not at all recommend to use condensate pot (even for high pressure steam as high as 140bar). Now, I am more convinced that condensate pot is not necessary for pressure transmitters because of the temperature gradient effect, rule of thumb 1degC/mm at steady state (zero flow).
