Production of steam from electric energy

In localities where hydroelectric power is abundant and steam loads are readily available, the production of steam from electric energy has proved to be a highly satisfactory means of utilizing surplus and off-peak power. This method of producing steam is particularly advantageous where cleanliness is important and in small establishments having intermittent demand for steam. Although the production of steam by this method has had a wider application in Canada, where the total installed capacity of such equipment exceeds 1,500,000 kw, numerous installations, totalling about 200,000 kw, also have been made in the United States. The design and operation of the principal types of equipment used for this purpose are discussed in this paper.
