This paper explores the effect of plane-shaped cores and the value of load in high-power resonant wireless power transfer (R-WPT) system through the certain gap distance. Plane-shaped cores (Mn-Zn ...ferrite) were designed in the transmitter and the receiver with resonant coils for achieving a high power and a long transfer distance wireless power transmission with a high efficiency. The effective overlap area between the transmitter and the receiver was expanded. The circuit equivalent formulas are used to analyze the specific parameters design in this system considered the requirement output power and efficiency. Meanwhile, this paper presents the reason of frequency bifurcation by analytical model and experimental prototype. In order to realize the performance of the plane-shaped cores system, related experiments are carried out and verified the influence of plane-shaped cores structure.
In view of the application scenarios and demand of mechanical equipment pump truck, design a pump truck MRO system based on the Internet of Things and Cloud Computing, and the overall structure, ...General structure are given, and the system function is designed. Using the system, the functions can be realized, such as pump truck remote data acquisition, diagnosis processing and production management.
In this paper, study on the combustion behavior and pollutant emission properties of the different types of coal and different ratio of blending coal have been done. The influence of the ratio of ...brown-blending coal on the combustion efficiency and NOx emission have been researched and concentrated ratio and method of pulverized coal have been get. The thermal-load distribution along the height of furnace and the control of the flue gas temperature at the exit of the combustion chamber have been discussed and the retrofit schema has been put forward Through reasonably blending coal, combustion efficiency is increased and NOx emission is decreased, which lay a foundation for widely applying the combustion technology of blending coal.
This paper studies on the application of “600MW stair differential pulverized coal distributor” in Yuanbaoshan Power Plant. It is the key equipment that keeps the stable combustion of pulverized coal ...in the boiler. It can decrease the pulverized coal density and granularity variation at milling exit. At the period of 168 hours examine test of No.3 unit, the test of pulverized coal density and granularity distribution was completed. The results show that the pulverized coal density and granularity distribution is better.
