The fly ash has a wide range of particles size and has a large amount of unburned carbon. As a raw material, the presence of the large particles and the unburned carbon will reduce the quality of the product. How to improve the utilization of fly ash has become one of focus points. In this work, hydrocyclone was adopted for classification after decarburization in a flotation column. Hydrocyclone showed a very good classification performance. In overflow, the particles were all smaller than 85μm. About 97.34% of the particles were smaller than 25 μm. Different fly ash content was selected to investigate its influence on the decarburization. The results showed that it made no obvious differences.

This paper represents a new interconnected architecture of Flight control System (FCS). It can solve the problems of massive equipment and large cross link information. The interconnected architecture adopts double CAN-Bus to construct a redundant flight control systematic bus. This paper will illustrate the characters of double CAN-Bus comparing with the characters of CAN-Bus firstly. Then it will present the bus controller hardware design, allowance design, network communication protocol, software flow and code design respectively. The experimental results show that the bus is running well, can satisfy the small vehicle control system of a high real time capability and node demand, at the same time system has high reliability, open etc.

In complex systems like flight control systems etc., reliability is as important as performance. In order to improve the reliability of flight control system (FCS), the fault- tolerant technique was adopted. Three parts of the FCS which are Flight Control Fault Tolerant Computer, Redundancy sensor and Servo-actuator have been explored. The key techniques have been solved, such as Redundant Disposition, Synchronism of the Redundant Channels, Data link and Communication of Channels, etc. The experimental results show that the system meets with the fly control system’s demand of reliability.
