| 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,尤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 interchangeability 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, instant 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. |
