1. What kind of flowmeter is good for measuring the flow rate of circulating gas in dry quenching?

It is recommended to use the Deltaba flowmeter, which is widely used in gas applications such as coke oven gas, blast furnace, converter, etc., with good results. Contact number: Technical specifications: Accuracy: 0.5-1% (R) Repeatability: 0.1% Range ratio: 30:1, Bidirectional measurement diameter range: 3mm~15m Temperature range: -200~+1240 ℃ Pressure range: Modified pressure range: 0-69MPa Measurement medium: gas, liquid, steam, and strongly corrosive media Pressure loss is small, energy-saving and reducing nuclear energy consumption, plug-in structure is easy to install. Generally speaking, the dry quenching circulating gas will be mixed with dust, so when using this type of averaging tube flowmeter for measurement, it is necessary to use a Xiangwan matched online blowing device or order a flowmeter that can be plugged in and out online to facilitate regular removal and cleaning of dust.

3. Relationship between coke oven gas pressure and flow rate

Relationship between coke oven gas pressure and flow rate: When the downstream pressure increases while the pressure remains constant, the flow rate decreases;

; When the pressure increases while the downstream pressure remains constant, the flow rate increases. Coke oven gas is a mixed gas composed of multiple gases, which has the characteristics of low flow rate, low density, tar, dust, moisture, etc. Therefore, measuring the relationship between pressure and flow rate of coke oven gas is much more complicated compared to single component gases such as oxygen and nitrogen, and obtaining accurate me Coke oven gas flowmeter

asurement values is also much more difficult. In recent years, we have attempted to use flow meters with different measurement principles, such as rotary flow meters, vortex flow meters, and thermal flow meters, on coke oven gas pipelines. However, due to the limitations of coke oven gas itself, the use of Jiehong Zheng flow meters is not very ideal. Ultimately, the vast majority of coke oven gas measurements still use the conventional differential pressure flowmeter. The main factors affecting the measurement results of coke oven gas flow rate are: (1) Ash accumulation coke oven gas inevitably contains dust and tar, so after years of use in the pipeline, dust and tar will inevitably deposit and form uneven thickness deposits inside the pipeline. (2) The density change of coke oven gas is a mixed gas composed of hydrogen, methane, carbon monoxide, unsaturated hydrocarbons, carbon dioxide, nitrogen, oxygen, and water vapor. In the case where the temperature, pressure, relative humidity of the measured gas are the same as the design value of the orifice plate, due to other reasons such as production process, the percentage of the volume occupied by each component of the measured gas has changed, resulting in inconsistent gas density with the design state, which will affect the accuracy of the measurement value. (3) Changes in pressure, temperature, and humidity of coke oven gas. Characteristics of coke oven gas:

1. Coke oven gas has a high calorific value of 16720-18810kJ/m3 and a high combustible content (about 90%).

2、 Coke oven gas is a colorless and odorous gas.

3、 Coke oven gas is toxic due to the presence of CO and small amounts of H2S.

4、 Coke oven gas contains more hydrogen, burns quickly
