Title: Apparatus and its using method for detecting explosion phenomenon of inflammable gas
Inventor: SHIMIZU TAMIO
IPC: G01N25/54
Filed: 1983-07-08
Abstract: PURPOSE:To measure the titled gas automatically and with high efficiency by providing a mixed gas supplying means for supplying the mixed gas containing an inflammable gas to be measured to each chamber of a reaction vessel basing on the result of a calculating means, a firing means and a means for detecting explosion phenomenon. CONSTITUTION:Automatic valves V1-V8 are operated to perform next operations. A gas C is supplied up to a prescribed pressure in a mixing vessel 3 after the vessel 3 is evacuated. Then gases A, B are supplied into the vessel 3 by similar procedures to produce the uniformly mixed gas of the prescribed pressure. Next, said mixed gas is sent to reaction chambers 1, 2 from the vessel 3 after evacuating the chambers 1, 2. A firing device 9 is operated to detect whether explosion is caused or not by an explosion detector F. If explosion is not caused in the reaction vessel, the uniformly mixed gas of another concn. is produced again in the vessel 3 by a command from a computer CP, refiring is performed by the procedure similar to the above-mentioned procedure and whether explosion is caused or not is detected. The limit concn. where explosion is caused can be known by repeating above-mentioned procedures.
