Intelligent pulse combustion system

Abstract

The invention discloses an intelligent pulse combustion system. The intelligent pulse combustion system comprises a gas pipeline, a combustion assisting air pipeline, a combustor and a control system; the gas pipeline introduces gas into the combustor; the combustion assisting air pipeline introduces air into the combustor; nd the control system controls coordinated work of the gas pipeline, the combustion assisting air pipeline and the combustor to realize intelligent pulse combustion control. The intelligent pulse combustion system realizes intelligent pulse combustion control through controlling the combustion state switching and the combustion lasting time of the combustor by the control system according to a deviated value between a detected industrial furnace actual temperature and a preset temperature. The intelligent pulse combustion system can realize precise control of a combustion atmosphere, improves the heat transfer efficiency, largely reduces the energy consumption, needs no online adjustment, can increase the burner load adjusting ratio, is simple and reliable, is low in manufacturing cost, and can reduce generation of NOx.

Description

technical field [0001] The invention relates to a control method and system for an industrial furnace combustion process, which can be widely used in metallurgy, electric power, chemical industry, petrochemical and other industries, and plays an important role in improving product quality, reducing energy consumption and reducing pollution. Background technique [0002] Modern industrial furnaces require automatic control of furnace temperature, especially during the heating and heat preservation stages of heat treatment furnaces. Correspondingly, automatic combustion control must be implemented. The two constitute the basis and core of thermal control of industrial furnaces. Combustion control methods are basically divided into two types: proportional combustion control and pulse combustion control. For different fuels and furnace types, its selection and deployment are very important, which determines whether it can meet the product process requirements and the advanced the...

Problems solved by technology

[0003] At present, continuous combustion control forms such as proportional control and double cross limit control are generally used in China, but they are often restricted by the key link of fuel quantity measurement and adjustment, and the control effect is not good. In recent years, pulse combustion control technology has appeared internationally. Overcoming these disadvantages, it is called "the development direction of future industrial furnace control technology"
