What is an electric steam boiler?

Electric steam boiler is a unit for steam production that uses thermal energy developed by electric elements to heat the water inside a closed tank or shell. In addition to the heat source, the electric steam boiler is similar to its basic design and operation as other types using gas or oil furnaces to heat water. These boilers fall into two categories - resistance and electrode - types defined by elements used in their design. Resistance boilers have conventional resistant submersible elements similar to those used in the kettle, while the electrodes types use the current passing through the water between two electrodes to secure the heat source. Although they are more expensive to operate, electric steam boilers offer operators several advantages over gas and oil types, including zero emissions, without fuel leakage and easy use.

steam production for food, laundry and hospital equipment is generally achieved using a steam boiler. A similar conventional water heaterThese boilers source of thermal energy to cook water in a closed tank for generating steam. The heat source can be a flame of gas or oil or in the case of an electric steam boiler a set of electrical elements. Electrically heated boilers are quite expensive to operate, but offer many advantages that compensate for costs. These include simple operation, low maintenance and zero emissions.

electric steam boilers with resistance have one or more resistance submersible elements. These elements are similar to those used in the kettle and consist of a resistance core enclosed in a sealed tube. The elements are usually long, the U -shaped units pass through a partition or a flange screwed to the boiler body and connect to the outside of the boiler with an element immersed in the water inside the tank. When the electric flow is applied to these elements, the resistance that offers its passage of the core of the elements causes to heat up,Which in turn warms the water.

Electrode boilers have much higher outputs than resistance types and use a set of conductive bars or electrodes submerged in boiler water. When electrical current is applied to the electrodes, the water becomes a conductor and resistance to passing the current between them. This causes water to heat in the same way as the resistance core in the submersible element. This type of electric steam boiler is generally used where large steam volumes are required and are able to produce up to £ 110,000. (242,000 kg) steam per hour. Resistance boiler elements generally produce fewer steam with average values ​​between £ 50 and £ 13,000. (110 and 28,600 kg) per hour.
