高温低氧燃烧技术的应用基础研究

HTAC (High Temperature Air Combustion) is a kind of new technology which has been empoldered since the end of 20 century. it has much virtue of extra low NOx emission and high energy-efficiency and optimize energy using.HTAC technology had developed the phase of industrial application and the key technology of HTAC is keep secrted in developed country. HTAC technology is beginning application and the key technology begin to be studied in our country. Application fundamental research of High Temperature Low Oxygen Combustion Technology in the aspect of theory numeration of the industrial applicaion and extra low NOx emission have biger difference in our county than in developed country. .Application fundamental research of HTAC technology had been studied by the way of raction engineering and the many scale character of complex process industry. The resistance losing of airflow via regenerator and the relation of the switch time of the system of regenerate combustion with the heating parameter and the factor of NOx emission had been studied in laboratory（heating load is 0.08MW）. The new technology of achieving low oxygen in the area of combustion had been developed. The mathematical model of the velocity field for the regenerate reheating furnace was established with the commercial software CFX.. The industrical experimentation which heating load is 0.8MW had been accomplished in HTAC ladle preheating system. The industrical application experimentation which heating load is 32.6MW had been finished in HTAC regenerate reheating furnace. The model of the resistance losing of airflow via regenerator had been based, The new concept of best concentration of oxygen had been declared, the new technology of achieving low oxygen in the area of combustion had been developed. The calculation theory of HTAC industrical application had being upbuilded.13 papers had been finished, 3 graduate students are been trained. 3 patents had been applied.Application fundamental research of HTAC technology had provided calculation theory of HTAC industrical application,it will accelerate application of HTAC in our country..
