Abstract

In order to solve the problem of peak load regulation in winter and new energy consumption in China, zero-output technology of low-pressure cylinder was proposed. On the basis of studying a large number of literature materials, this paper briefly introduced the application scenario and technical principle of low-pressure cylinder zero-output technology, and discussed the theoretical research and application of low-pressure cylinder zero-output technology in practical engineering. As a kind of power plant operation scheme, low-pressure cylinder zero-output technology has the characteristics of significant peak regulation capability, low reconstruction cost and high economy. Although this scheme has a very broad development prospect, there are still many practical problems to be solved urgently if we want to promote its application.

Abstract

Phosphoric acid fuel cell (PAFC) has become one of the fastest growing commercial fuel cells due to its short start-up time, no pollution and simple structure. According to the first and second laws of thermodynamics, the energy, exergy and ecology performances of PAFC were studied. The mathematical expressions of electric efficiency, output power, exergy destruction rate, exergy efficiency, ecological function and ecological coefficient of performance for fuel cell were derived. Considering the trade-off between various optimization criteria, the optimal working area of PAFC under different performance parameters was obtained. Finally, the effects of some main operating conditions and design parameters on the performance of PAFC system were discussed in detail. This work considers the benefits and losses of energy from the perspective of protecting natural resources, and the results can provide some theoretical support for the design of high-performance PAFC system.

3. The Study on the Generation of Persistent Free Radicals in the Explosive Industry Area

Abstract

Phenolic compounds and transition metals exist in wastewater having a large number of emissions due to the discharge of polluted wastewater from the explosive industry. And these two substances are important factors that affect the generation of persistent free radicals (PFR). However, the generation of more toxic and harmful PFR is unclear in wastewater from the explosive industry. In this study, the dissociation reaction of phenol on transition metal oxides ZnO to form PFR has been explored by the density functional theory (DFT) calculation. The dissociation of phenol on the ZnO surface is an exothermic and barrierless reaction process, which indicates that PFR can be formed in the wastewater of the explosive industry. Thus, more attention should be paid to the toxicity of PFR in the wastewater produced by the explosive industry.
