Experimental research on Spontaneous co.bustion Tendency of High Volatile Blended co.ls

Engineering（科研） 2013年第3期5卷 309-315页

作者： Jinfeng Ma Fei Shao Junrui Shi Zhijia Xue Shuqun Wang Hongtao Li Huangxin Zhang mi ninth design & research institute co. Ltd. Changchun China Shenyang institute of Engineering Shenyang China

Experiment of oxidation characteristics with slow velocity of high volatile blended co.ls was investigated in the surroundings of low oxygen co.ditions, which gives three kinetic factors in the step of low temperature through the methods of thermo gravimetric analysis, the co.ts-Redfern integration and Achar-Brindley-Sharp-Wendworth. The results of calculation show that activation energy and pre-exponential factor increase with the reaction process, and tendency of spontaneous co.bustion of the blended co.l have changed. The experimental results show that the type of absorbing oxygen is mainly physical adsorption and calorific value is very small during increasing weight. Volatile of blended co.l releases before single co.l and co.bustion temperature of blended co.l is between one and other single co.ls. If the oxygen co.tent is below 16% in the milling system, explosion-proof effect on high volatile blended co.l can be obtained.

Three-dimensional CFD simulation of inlet structure flow in pumping station based on Eulerian solid- liquid two-phase flow model

Sediment deposition in the pumping station has a huge negative impact on unit *** three-dimensional CFD method has been used to simulate inlet structure flow in pumping station based on the Eulerian solid- liquid two-phase flow model. The numerical results of the preliminary scheme show that sediment deposition occurs in the forebay of pumping station because of poor flow pattern therein. In order to improve hydraulic co.figuration in the forebay,one modified measure reco.structs water diversion weir shape,and another measure sets a water retaining sill in the approach channel. The simulation results of the modified scheme prove that back flow in the forebay has been eliminated and the sediment deposition region has also been reduced.
