Application result shows that ESW shock wave soot blower has evident soot blowing effect. After blowing, exhaust gas temperature has been reduced by 29℃, superheated steam output has increased by 7t/h, and saturated steam produced by the boiler itself has increased by 2t/h. Heat transfer efficiency and superheat ability of the waste heat boiler have been effectively enhanced and the energy conservation effect is evident.
All changes and reactions of wares in tunnel kiln relate to thermo-technical state of the tunnel kiln, especially thermo-technical state of the preheat zone having great effect on quality and output of wares in the tunnel kiln.
Compared with many other developed countries, there are still large number of problems of energy actuality in our country, for example, low energy utilization level and renewable energy proportion, and the ratio of investment to output falls far behind international advanced level.
In order to stabilize the lean burn engine the torque output, an electronic control systemof lean burn engine was been developed by author. When the A/F of the lean burn enginechanges from the state of lean burn (A/F=21) to the state of less oxygen (A/F≤14.7), thesystem adjust throttle and ignition time automatically so as to obtain constant torque output.
In this paper , after analyzed many effect factors of the mill storage pulverizing system in the 200MW unit in GUIYANG power plant, researched the burthen change charateristic of the pulverizing system. Applied fuzzy control rule including many variables input and many variables output and set up the subject function including three input variables which affects pulverizing system. Devised fuzzy controller and constituted fuzzy decision-making using fuzzy control rule.
