A study of delayed spontaneous insulation fires
نویسندگان
چکیده
The phenomenon of gaseous thermal explosion within inert insulation material filled with a combustible evaporating fuel is considered. A novel approach to estimate the activation energy is suggested using the available experimental data and the relevant theoretical predictions concerning the delay ignition time. 2003 Elsevier Science B.V.

Analysis of the Influence of Construction Insulation Systems on Public Safety in China
With the Government of China's proposed Energy Efficiency Regulations (GB40411-2007), the implementation of external insulation systems will be mandatory in China. The frequent external insulation system fires cause huge numbers of casualties and extensive property damage and have rapidly become a new hot issue in construction evacuation safety in China. This study attempts to reconstruct an ac...

Thermal insulation materials protects internal surface of the motor casing in contact with the hot produced gases, extreme turbulence flow and high pressure due to combustion propellant. Insulation Materials in the rocket motor covers the inner surface of the motor casing and protect the body against the damage caused by extreme and short-term heat, intense turbulent flow and high pressure. O...
متن کاملImproper Fuse Wire Replacement, and Possible Association with Commercial Fires
The rewireable fuse or cutout is widely used in Bangladesh and elsewhere, in spite of the very real danger of improper replacement of fuse wires. To assess the problem, a preliminary survey of buildings, electrical shops, and electricians were conducted. The majority of buildings and retail establishments were found to use fuse wires. Electricians were found to use copper of arbitrary thickness...
متن کاملInvestigation of leakage current flow through wooden poles structures on overhead distribution system
Insulation degradation leading to leakage current flow through the high voltage insulator is a major problem faced by various power distribution utilities. The excessive leakage current flow into the wooden supporting structures (wooden cross-arm and pole) leads to pole-top fires and subsequently power cut-off. Most prior researchers focused on flashover phenomena of insulators rather than inve...
متن کاملCauses of wildland fires, associated socio-economic impacts and challenges with policing, in Chakari resettlement area, Kadoma, Zimbabwe
Zimbabwe is among the most fire prone countries in Africa south of the Sahara. Annually over 1 million hectares of land are destroyed by wildland fires during the fire season which runs from July to November. Wildland fires are caused by several agents, cost huge socio and economic loses and are difficult to police. The objective of this study was to evaluate the causes of wildland fires, assoc...
