Dipak K. Sarkar, in Thermal Power Plant, 2015 13.2.2 Low drum level. A high-pressure boiler has insignificant water capacity compared to its steaming rate. Any interruption of feed to the boiler for any reason, for a couple of minutes, sometimes even for less than a minute, will cause the disappearance of the water level from the gauge glass/level indicator mounted on the drum.

Cyclone Boiler - an overview | ScienceDirect Topics

Parallel co-firing involves the installation of a completely separate external biomass-fired boiler in order to produce steam used to generate electricity in the power plant. Instead of using high-pressure steam from the main boiler, the low-pressure steam generated in the biomass boiler is used to meet the process demands of the coal-fired
