摘要随着城镇燃气多气源供应格局的形成,不同气源之间互换带来的问题日益凸显。针对民用大气式燃烧器,设计了一种用于实验室研究的燃气互换性综合实验系统,包括动态配气系统和灶具性能测试系统。该系统配气精度高、响应速度快、即配即用、数字化灵活配气、连续可调,光其在测定燃具适应域时独具优势;解决了现有系统占地面积大、混气不均、滞后性大、排空浪费气源等问题。

Abstract: In view of the pattern of multiple gas supply in cities , a series of problems about gas interchangeability are brought to our attention . For atmospheric gas burner, integrated gas interehangeability and blending test system has been designed for laboratory research , which includes dynamic gas-mixing system and combustion characteristics of gas appliances testing system . The devices have the advantages of small and accurate multi-gas blending , fast respond speed, instan blending and use , digital display instrument , and continuous gas flowing . Besides, the system has huge advantages in determining the flexible range of gas appliances to different gases . Many problems have been solved perfectly by using this system , such as large space occupation , the unevenness of gas mixture, long time lag, and wasting gas.
Key words : gas interchangeability , multi-gas blending , high precision , fast respond speed

渐形成,现存气源之间能否互换,以及与已有燃气具是否匹配的问题逐渐被提上日程。我国对燃气互换性的研究工作刚刚起步,目前尚无统一的燃气互换性理论技术可借鉴。国外的燃气互换性判定方法究竞是否适
用于我国,亦需大量实验工作来验证。因此,建立多气源互换性测试及燃气具气质适应性测试实验平台,通过大量实验来探索和总结我国的燃气互换性理论,指导和完善我国燃气具的综合设计与技术升级,对我国实现燃气的顺利互换具有重大意义。
