| This project is a part of Aquefuel manufacturing system, and the aim is to make a kind of clean, economy, practical burnable gas. In this paper we call this type of burnable gas as arc gas. Through importing the patent technique of the AquaFuel and Magnegas manufacturing system from the United States, we have developmented the experiment field in Guangzhou and Shaoguan, and initiate the research. It took about two yesrs study and continuous trial and error to finish the manufacturing equipment in the domestic for the first time at the end of the year 2002.The paper pulls weight on industries application, and introduces the concept of arc-gas, arc yielding manufacture equipment and its craft, the model of arc yielding control system, and the theory of Predictive Functional Control and its application in arc-gas yielding system. Besides, the PEC-PID transparent control method is also given.The control system deals with the signal sampling and control of motor, switch, valve, temperature, air pressure, electric voltage and electric current. What's more, the connection diagram of control parts, the flow chart of the software, and some control HMI are given. In order to guarantee the system reliability, the system adopts the PLC as the core of the control system, and the touch panel HMI as accessorial part.Accroding to the field data, the characteristic diagram of the arc gas under different conditions are drawn.The manufacturing of arc gas still lies in the start stage wether in local or in the international. If the gas can be succeefully used as public product or industry product, it must be a milestone of energy innovates in the history of mankind. And it will make the energy continuous and repetition, which have great significance for the human living environment ameliorating. |
