ABSTRACT
The thesis introduces the field of application and background of development of gas burners. Especially, the economy develops rapidly in our country. The development of Industries and city needs the high quality and clean energy. Therefore, gas burners are applied and developed rapidly. In the process of burning, it is important to control Nox. This is an important environment. In order to obtain the property, gas burner need be controlled. The thesis discusses existed control algorithms including Dahlin and fuzzy logic algorithms. It is a base of analyzing and applying Eclipse Burners. The history of Eclipse Inc. is introduced and Eclipse Eclipse burners are sorted. It describes 15 kinds of Eclipse burners and one burning monitor. It analyzes the characteristic of gas burners, property and application field. Applications of Eclipse gas burners are described for example of Chinese Heavy Truck Company Group to heat air in the assembly line. Eclipse burners can meet requirements of production, operation, running and of equipments. It analyzes and designs Eclipse burner AH-MA V.210 including its property，advantage and operation principle. Furthermore, it analyzes the structure of control system in gas burners. The design method of burner structure is obtained. Sizes of burner structure, size of air let in pipe and the location of the pipe are designed. The analysis of control system is obtained for control method, fire system and main gas burning plate. After analysis of control system, the algorithm of control is built. This paper analyzes the basic structure, components and control objective. After comparing the two level robust micro controller of burner system, it adds the control of the airflow in the control system that has more control variables for the robust adaptive control in the burner system. Thus, the process of burning is controlled in high performance, and it guarantees the quality of burning and least pollution emissions. The results of simulation describes that the robust adaptive control has a better dynamic response. It improves property of control algorithm and computer simulation is obtained. The results of analysis and simulation indicate that the adaptive control algorithm can control gas burners better.
