In this embodiment, the number of gas pipes 30 is four, which are respectively connected to mixed gas pipelines, blast furnace gas pipelines, coke oven gas pipelines, and converter gas pipelines. In other embodiments, the number of gas pipes 30 can also be set to 2, 3, 5, etc., and the gas pipes can also include natural gas pipes, which can be set according to actual conditions, and are not limited here.

[0045] Further, in the plurality of gas pipes 30, the end of each gas pipe 30 connected to the gas pipeline and the end connected to the gas mixing tank 10 are provided wit...

Embodiment 2

[0054] Based on the same inventive concept, the present application also provides a coal gas calorific value detection device, which includes the gas premixing device and the calorific value instrument room 80 in the first embodiment.

[0055] Through the gas calorific value detection device provided by this application, various types of gas calorific value measurements developed for burners can be realized, which solves the problem that the calorific value measurement methods of industrial furnaces and gas pipeline networks in the prior art cannot meet the requirements developed for burners. Technical issues of calorific value measurement of various types of gas.

Embodiment 3

[0057] Based on the same inventive concept, the present application also provides a gas calorific value detection method, such as figure 2 As shown, the gas detection method is applied to a gas calorific value detection device, and the detection method includes:

Description

technical field [0001] The invention relates to the technical field of energy and thermal engineering, in particular to a gas premixing device, a gas calorific value detection device and a method. Background technique [0002] Gas calorific value refers to the heat released by complete combustion of gas, which is an important basic thermal parameter in the professional field of metallurgical thermal energy. When testing the maximum and minimum combustion capacity of the burner, it is necessary to accurately grasp the calorific value of the combustion gas to avoid misjudgment of the air gas ratio. Therefore, accurate measurement of the calorific value of various types of gas is of great significance for the development of new burners. [0003] Some large iron and steel enterprises in China have large-scale professional laboratories for performance testing and research and development of burners in the metallurgical industry. The developed burners have achieved good technical ...
