The Research Of Pulse-burning Technology And Periodical Optimization In Regenerative Heating Furnace

The lack of the energy sources has already restricted the continuable development of domestic economy. As one of the main energy-consuming equipment in metallurgy enterprise, the strategy of automatic control of heating furnace is an important research topic in the field of related process control. How to design an excellent automatic control system, which can not only ensure the heating quality and enhance manufacture efficiency, but also economize energy consume, ensure good burning quality and reduce the pollution of the environment, are the main problems waiting to be solved.Based on the design of automatic control system of Walking Beam Double Regenerative Heating Furnace, we introduce different kinds of solution in saving energy. After analyze the energy exchange in heating furnace, we get the thermal equilibrium of pulse-burning and the optimize model of exchange period, which deduced according to heat balance of supply and consumption. Furthermore, in order to keep the best burning quality all the time, the dissertation presents a control strategy, which can alter the quantity of the burner.The pulse-burning technology based on double regenerative heating furnace has greatly enhanced the thermal efficiency of heat recycle. It has already applies in metallurgy enterprise what increased the convection's intensity of hot airflow and also enhanced the heating quality and manufacture efficiency. By analysis of thermal equilibrium, the pulse-burning technology based on double regenerative heating furnace is an excellent strategy, which will be the reference in saving energy of heating furnace. The dissertation introduces the application in the factory at the last chapter, as well as the exchange period and control strategy. The results show that the effect is evidence in saving energy.
