Shell Boilers Spirax Sarco

Shell boilers often have one furnace tube and burner. This means that control systems are fairly simple. Although shell boilers may be designed and built to operate up to 27 bar, the majority operate at 17 bar or less. This relatively low pressure means that the associated ancillary equipment is easily available at competitive prices. Superheaters - an overview ScienceDirect TopicsThe superheater heats steam above the saturation temperature for a particular boiler pressure. Superheater tubes have steam on one side and hot combustion gases on the other. Surface temperatures are higher here than the boiler tubes. The passage of heat from the hot flue gases through the tube wall increases the temperature to about 565°C.
