[Abstract]:The dry hollow reactor in operation can be monitored (inspected) to avoid the fire loss. In order to overcome the limitation of several existing methods of monitoring and testing reactor operating state, the characteristic gas total volatile organic compounds (TVOC).) produced by dry hollow reactor insulating material bisphenol A epoxy resin under superheated condition were found out by experiment. The change of TVOC volume fraction with superheating temperature, superheating time, wind speed and relative humidity was studied by simulating the overheating failure of dry hollow reactor. The experimental results show that the volume fraction of TVOC increases with the increase of superheating temperature, and when the superheating temperature exceeds 160 鈩，
