Shell Boilers | Spirax Sarco

This relatively low pressure means that the associated ancillary equipment is easily available at competitive prices. Disadvantages of shell boilers: The package principle means that approximately 27 000 kg/h is the maximum output of a shell boiler. If more steam is required, then several boilers need to be connected together.

Tips. Having said this, it is necessary to be mindful of the following when heating with saturated steam: Heating efficiency may be diminished if steam other than dry steam is used for process heating. Contrary to common perception, virtually all of the steam generated from a boiler is not dry saturated steam, but wet steam, which contains some non-vaporized water molecules.

West Burton power stations - Wikipedia

There are three stages of H.P. feed heating with six heater shells arranged in parallel pairs, a de-aerator and three low pressure heaters. Steam is bled from the main turbine H.P. exhaust to drive the main boiler feed pump turbine, which exhausts to the feed heating system to improve the overall cycle efficiency.
