Pulverizing system equipped by fan mills uses “three medium” (ie. low-temperature furnace smoke, high-temperature furnace smoke, hot air) for drying coal, especially in large-scale plants burning lignite. A constantly increasing unit capacity leads to a more complicated design for pulverizing system, with a heavier weight of furnace smoke tube. This paper focuses on a research of water-cooled membrane...
With the continuous growth of world economy and energy shortage recently, more and more attention has been paid to geothermal resources. Geothermal electricity generation also has been increasing year by year. At present, there are three main technical problems which hinder the development of geothermal power, the three technical problems are the reinjection, corrosion and scaling of geothermal field...
An experimental study on the equilibrium moisture content of ash and bottom ash under the various factors was performed, and regression was conducted by semi-empirical equation with experimental data, obtained quite good regression result; the article could provide experimental data for related theory and experimental investigation.
This article adopts SIMPLE algorithm, and uses corrected ?? - ?? turbulence model and non-staggered grid pressure interpolation method to have numerical value emulation for cyclone separators' flowing field. By studying flowing field property, we proposed optimum separator redesigning plan and have tested it in industry experiment, with practical results excellent.
This article introduces the three kinds of solar thermal power systems existing in the world, and analyzes the key technologies affecting the continuous and stable running of solar thermal power plant (STPP). According to the fact that STPP can't operate stably and continuously, the article puts forward a new running mode with an auxiliary boiler. The auxiliary boiler plays three roles in the system,...
