Abstract
The invention relates to a method for the operation of a steam thermal engine, whereby the hot steam from a working medium is converted into kinetic energy, by means of a pressure-releasing device ( ). The working medium is heated in a boiler ( ) to a low temperature, preferably boiling point at a low pressure, steam is taken from the boiler ( ) to a pressure chamber ( ), in which the steam is heated to a higher temperature. Liquid working medium (or condensate) is injected from the boiler ( ) into the pressure chamber ( ) whereupon the working medium is instantaneously evaporated, such that the pressure in the pressure chamber ( ) rises markedly and the steam is fed from the pressure chamber ( ) to the pressure-releasing device ( ).
