Spontaneous combustion of hydrogen

Spontaneous combustion of hydrogen

Date: March 4, 1922
Creator: Pothmann, PH & Nusselt, Wilhelm
Description: It is shown by the author's experiments that hydrogen which escapes to the atmosphere through openings in the system may burn spontaneously if it contains dust. Purely thermal reasoning can not account for the combustion. It seems to be rather an electrical ignition. In order to determine whether the cause of the spontaneous ignition was thermo-chemical, thermo-mechanical, or thermo-electrical, the experiments in this paper were performed.
