Method and apparatus for dampening noise occurring in liquid heaters operating according to the vacuum vaporization principle

摘要

A method for dampening noise occurring in liquid heaters operating according to the vacuum vaporization principle owing to pronounced vapor formation at the heating surfaces which contemplate opposing the formation of vapor bubbles at the heating liquid through the action of obstruction or damming up means. The equipment for the performance of the aforesaid method employs obstruction or damming-up means arranged at the vacuum vessel or container which oppose the formation of vapor bubbles at the heating liquid.
