- Electric steam boiler
Electric steam boilers are used to generate steam for process purposes in many locations, e.g. laundries,
food processingfactories and hospitals. Although they are more expensive to run than gas-fired or oil-fired boilers they are popular because of their simplicity and ease of use. Because of the large currents required, they are normally run from a three-phaseelectricity supply. They convert electrical energyinto thermal energywith almost 100% efficiency but the overall thermal efficiencyis variable, depending on the efficiency with which the electricity is generated.
An electric steam boiler emits no pollutants at the point of use but it may be responsible for off-site pollution, depending on the source of the electricity. It is a very inefficient way of using
fossil fuels because a thermal power stationconverts only about one third of the fossil fuel energy into electricity. However, if the power source is a wind turbineor water turbinethen an electric steam boiler could be seen as a very environmentally friendlymachine.
