Plant Engineering | When to use electric steam boilers

Sep 06, 2001 · A packaged electric steam boiler may be a more economical solution (Fig. 1). It can keep steam-consuming operations running at full speed, while the big fossil-fueled boiler takes the summer off or has to be maintained or repaired. Fig. 1. Packaged electric steam boilers only require electricity and feed water. What about electricity costs?

How electricity is generated - U.S. Energy Information

Nov 09, 2020 · Steam turbines are used to generate the majority of the world's electricity and they accounted for about 48% of U.S. electricity generation in 2019. Most steam turbines have a boiler in which a fuel is burned to produce hot water and steam in a heat exchanger, and the steam powers a turbine that drives a generator.

Feed Water Treatment to Avoid Corrosion - Engineering ToolBox

Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Corrosion is a major problem in steam systems with high consumption of make-up water. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems.

Boiler Efficiency and Steam Quality: The Challenge of

As water is lost rapidly and the steam/water mixture contains more and more steam, tubes may overheat. By the time the external water level detector eventually identifies a low-water level and shuts down the boiler, the steam distribution system will be laden with water and boiler tubes may have been damaged.
