Title: Gaseous fuel lighting-back preventer - uses jet pump to supply gas, driven by fluid which can quench flame, fluid being separated from gas before burner
Inventor: SCHNEIDER BERTRAM DIPL ING
IPC: F17C13/12
Filed: 1992-07-03
Abstract: The system prevents lighting back of inflammable gases from a burner to a tank (3) for the mixture.
