As to the boiler, the explosion energy, besides a few (about 3%-15%) consumption in tearing steel plates, pulling off in-situ fragments as well as with the boiler connected steam-water pipes, valves and main body outside, the energy of consuming for further tearing the container would be little as well, and most of the explosion energy will function as the form of shock wave on the surrounding environment, causing the destruction of buildings and casualties [4]. the magnitude of the blast wave is much higher than the one caused by a vapor cloud explosion occurring in an identical quantity of material.

Study on the Thermal Properties of High-strength Flame Resistant Vinylon Blending Fabric Zhang Shuo1,a, Chen Xuwei1,b, Li Yuling1,c, Du weiping2 1Kay Lab of Textile Science & Technology, Ministry of Education, Donghua University, Shanghai, China,201620 2The technology center of Shangtex, Shanghai, China,200336 a2100029@mail.dhu.edu.cn, bcxw@dhu.edu.cn, clylu@dhu.edu.cn Keywords: high-strength flame resistant , Vinylon fibers, thermal conductivity, heat resistance.
Material 1.1 Yarn The high-strength flame resistant Vinylon fiber, flame retardant viscose fiber and aramid fiber were blended into a high-strength flame resistant Vinylon blending yarns, with the blending ratio 25/25/50.
Thermal conductivity of sample The thermal conductivity coefficient means the energy transfer rate in the thermal diffusion process of the material.
The formula of thermal conductivity coefficient is as follow: (1) -- Thermal conductivity coefficient of the material[W/(˚C•m2)] -- Unit time heat energy through the fabric.

However, this application is limited within the demand of construction materials.
Experimental 2.1 Materials The raw FA used for the synthesis of zeolite-like materials was supplied by the Jingdezhen Power Station located in Jiangxi province, China.
Zeolitic materials with high decolorization ratio of 93.8% were successfully synthesized via alkaline fusion followed by hydrothermal reaction using alkaline fused FA as starting materials and NaOH as activator.
