Study on the Application of Drying Furnace Waste Gas Treatment Technology in Painting Workshop

With the continuous development of our country's economy, the demand for automobile is higher and higher after people's living standard is improving day by day. In just 40 years of reform and opening up, China's automobile production and per capita possession have made a qualitative leap and a breakthrough in quantity. Greatly promoted the automobile industry's great development

Comprehensive Energy-Saving Technology for RTO Flue Gas Waste Heat Utilization

In the automobile painting workshop, the oven will discharge harmful exhaust gas, the exhaust gas can be reused through the TNV system, the natural gas can meet the emission standard to the atmosphere after burning, and the high temperature gas discharged TNV the system can carry considerable heat. Utilization can effectively improve the economic benefits of the factory. At present, the more mature scheme is to heat the high temperature exhaust gas through the heat exchanger, which can reduce the steam consumption of the factory. Based on the analysis of the comprehensive energy saving content of waste heat utilization of RTO flue gas, this paper hopes to provide some reference and reference for readers

Development of gypsum plasterboard embodied with microencapsulated phase change material for energy efficient buildings

Phase change materials (PCMs) have been used in the development of building materials with higher thermal energy storage capacity. Especially, PCM incorporated gypsum plasterboard has been described to decrease the cooling demand of building by up to 35%. However, it’s significantly important to fabricate and characterise the thermal/physical properties of PCM-gypsum plasterboard accurately. This paper presented the fabrication process and property measurement of gypsum plasterboard integrated with microencapsulated PCM (mPCM). Property measurement included scanning electron microscope (SEM) technique, sting, density measurement, compressive strength test, and thermal conductivity testing. The characterisation results show that: (i) the gypsum plasterboard enhanced with 5% and 15% PCM claim 5.36 and 4.34 MPa respectively; (ii) with the addition of 15% PCM, the gypsum plasterboard presented the lowest value of thermal conductivity as 0.139 W/mK; (iii) The mPCM-gypsum plasterboard also operates longer period of time than gypsum plasterboard with higher temperature of roughly 1.5 °C especially during discharging period; (iv) The mPCM-pasteboard provided 0.4 W/min higher stored energy than gypsum plasterboard due to the addition of mPCM

On Six Solutions for m

Under the assumption of two coupled parallel subsuper solutions, the existence of at least six solutions for a kind of second-order m-point differential equations system is obtained using the fixed point index theory. As an application, an example to demonstrate our result is given

A hybrid performance evaluation approach for urban logistics using extended cross-efficiency with prospect theory and OWA operator

Urban logistics performance evaluation can provide reference for further improving its level. However, most performance evaluation for urban logistics premises that decision-makers (DMs) are completely rational, which may not conform to the actual situation. Therefore, this article aims to consider the DMs’ psychological factors in the performance evaluation of urban logistics. Specifically, the cross-efficiency evaluation (CEE) method with the DMs’ psychological factors is used to measure the urban logistics efficiency in the central area of Yangtze River Delta (YRD) urban agglomeration in China in 2019. The main contributions in this article are to propose a hybrid CEE method with prospect theory and ordered weighted average (OWA) operator for urban logistics industry and to expand the evaluation perspectives of urban logistics performance. The main conclusions are obtained: (1) The DMs’ optimism level can indeed affect the efficiency value and ranking of urban logistics. (2) The aggregation based on the OWA operator is fair and reasonable because it can make all self-evaluation efficiencies play the same role. (3) To make the efficiencies and rankings of urban logistics in the central area of the YRD have credibility and discrimination, the DMs’ optimism level range is best between 0.8 and 0.8177
