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
