Recently, the office of the Municipal Green Power Improvement Engineering Headquarters held an on-site experience exchange meeting of the city's high-efficiency and environmentally-friendly pulverized coal boiler substitution and reconstruction project in Shandong Qidu Pharmaceutical Co., Ltd., and 50 project managers of high-efficiency environmental protection pulverized coal boilers were on hand to observe the scene. Shandong Qidu Pharmaceutical Co., Ltd. 35t/h high-efficiency environmental protection pulverized coal boiler project, reported the progress of the city's high efficiency and environmental protection pulverized coal boiler replacement and reconstruction project in October. Qidu Pharmaceutical, Yinshilai, Shengshida, and Dongfang Chemical made presentations on typical experiences. They provided experience for the construction of a high-efficiency environment-friendly pulverized coal boiler, and enhanced the confidence of high-efficiency and environmentally-friendly pulverized coal boilers in commissioning safe operation.
Compared with ordinary direct-fired coal boilers, the indicators of high-efficiency pulverized coal boilers have obvious advantages. The thermal efficiency is increased from 65% to 90%, and the fuel burnup rate is increased from 75% to 98%. Steam increased from 6 tons to 10 tons. The city has implemented 50 new enterprises with 58 sets of 1327.7 steam tons of high-efficiency environmental protection pulverized coal-fired boilers, replacing 79 coal-fired boilers with 118 sets of 118 tons of steam tons. It is expected to save 408,240 tons of standard coal annually, and reduce 329 tons of soot, 2,365 tons of sulfur dioxide, and nitrogen oxides annually. 1850 tons. When the operating load of the ordinary power station boiler is lower than 50%, it cannot be operated normally. The high-efficiency environment-friendly pulverized coal boiler can still operate normally under 30% load, and unstable operation will occur when it is lower than 15%. High-efficiency environmental protection pulverized coal boiler technology The advantage is very obvious.
The city's two high-tech and environmentally friendly pulverized coal preparation centers with an annual production capacity of 1 million tons, specially designed for the city's high-efficiency and environmentally-friendly pulverized coal boilers, can produce 2 million tons of high-efficiency environment-friendly pulverized coal, which can basically satisfy the city. Efficient environmental protection pulverized coal boilers' powder needs.
Are such issues only because of your cylindrical grinding machine?
Causes of geometry faults such as improper circularity and cylindricity as well as surface roughness could be the insufficient machine precision or the balance of grinding stones. However, in many cases, all those issues may be caused by the accuracy of the "Center Hole".
If you feel something should be improved, please first check the accuracy of the center hole. Not only can the causes of accuracy failure be because of center hole, but the "Centering machine" and "Center Hole Grinding Machine" can be the causes, too.
"2M8015" created by a highly precise Machining Center manufacturing technique
XINXIANG SUNRISE's machining center, well known for its excellent precision and long lifetime, is highly appreciated by world-class machine manufacturers. And "2M8015", SUNRISE's Center Hole Grinding machine, is developed by utilizing SUNRISE's designing philosophy and essences of the manufacturing technique.
2M8015 is a precise center hole grinding machine capable of grinding both center holes accurately without turning the work pieces. Delivery of 2M8015 into the market made a step forward to the future potential of extra precision cylindrical grinding machines.
The accuracy of the center hole influences that of cylindrical grinding greatly. The grinding motion of the unique grinding stone of 2M8015 is capable of grinding the center hole into the super-accurate polygonal shape with a deviation of 2μm or less, and this can only be realized by the cutting edge technology of SUNRISE. The center hole, which is polygonal-shaped based on the three-point support principle, is in contact with the spindle stock of the cylindrical grinding machine and the center of tailstock at three points precisely and securely. This makes possible the further higher grinding accuracy using your currently available cylindrical grinding machines.
