在详细分析了蓄热式高温空气燃烧技术的主要特点的基础上,针对某公司拟开发的“蓄热式高温空气燃烧实验炉”的设计要求,进行了数值优化计算和控制方案设计。所设计的实验炉其主要特点表现在以下几方面:蓄热烧嘴及蓄热体可方便拆装,便于对不同材质和不同结构的蓄热式烧嘴进行研究;设有数根可灵活调节流量的炉底冷却水管,保证实验期间的炉温稳定;在蓄热体内和炉膛等重点研究对象中都埋有数量不等的热电偶,可通过监控画面、历史趋势、数据报表等方便地得到相关实验数据;实验炉的上位机组态软件采用著名的工控组态软件iFIX,使控制系统具有良好的开放性、安全性和扩展性。所设计的“蓄热高温实验炉”为今后进行高水平的实验研究提供了稳定可靠的实验平台。
Based on the detailed analysis of the main features of regenerative high temperature air combustion technology, numerical optimization calculation and control scheme design are carried out according to the design requirements of “a regenerative high temperature air combustion experiment furnace” to be developed by a company. The main features of the design of the experimental furnace in the following areas: regenerative burner and regenerator can be easily disassembled, easy to different materials and different structures of regenerative burner research; with a few can be flexibly adjusted flow Of the bottom cooling water pipe to ensure stable temperature during the experiment; in the heat storage body and furnace and other key research objects are buried in a number ranging from the thermocouple, through the monitoring screen, historical trends, data reports and other easy to get relevant Experimental data; experimental furnace PC configuration software using well-known industrial configuration software iFIX, so that the control system has good openness, security and scalability. The design of the “regenerative high temperature experimental furnace” for the future high level of experimental study provides a stable and reliable experimental platform.
