Prof Mauro Cavallini

Abstract

Hydro-aeolian trompes, instead of water-wheel driven bellows, were widely used in Italian metallurgical plants up to the 19th century. They provided a blast of wet air suitable to feed the tuyères of pyro-metallurgical plants. The air was drawn by Venturi effect into a falling stream of water, separated in a barrel after a fall of 5–10m and carried in a pipe at a pressure of less than 1m of water (10kPa). Two examples are given of the application of the trompe, to an iron blast-furnace and to a lead cupellation furnace in the Papal State at the end of the 18th century.
