Gas industry

Brief description:
The analysis of oxygen content plays a vital role in the purification process of coke oven gas. If the oxygen content in the coke oven gas exceeds 1.2% VOL, it will easily cause the electric tar catcher to explode. Therefore, in order to avoid major accidents, the accuracy and reliability of oxygen content analysis data must be guaranteed. However, because coke oven gas contains tar, naphthalene and other easily condensable substances, the sampling system of the oxygen analyzer is often blocked, which reduces the reliability of the oxygen content measured by the analyzer. According to preliminary statistics, nearly 80% of the inaccurate analysis or failure events of the oxygen content analyzer in coke oven gas were caused by the irrational and imperfect design of the sampling system. Xinze Technology gas analysis technology can accurately and reliably measure the gas content in coal gas, providing a complete gas analysis solution for the gas industry.

Application areas:
Coke oven gas, dry quenching gas, gas stove gas, blue coal gas, water gas, semi-water gas, lignite drying gas, etc.

  • Gas calorific value composition analysis solution
  • Analysis and resolution of oxygen content in coking gas


概述 Product Overview


Mixed gas is the main fuel produced by iron and steel enterprises. It is mainly composed of blast furnace gas, coke oven gas and converter gas. The calorific value of the mixed gas is an important measurement index, and its accuracy directly affects the gas measurement and balance of the entire plant. At present, iron and steel enterprises mostly use the "combustion method" calorific value instrument for online analysis of the calorific value. The flammable gas calorimeter made by the principle of combustion method is not scientific in theory and has many defects in design. The deviation of the air-fuel ratio during combustion has a great influence on the accuracy of detection, the burner is also easily blocked, and the maintenance is large. In addition, because the measurement principle determines that it is difficult to accurately calibrate, the combustion method usually uses a standard calorific value gas for calibration, which is difficult to reflect the calorific value characteristics of the mixed gas, and it is also a combustion method calibration, which has its own suspicion of calibrating itself! It often causes gas plants The output calorific value does not correspond to the calorific value output by the same equipment at the application site, causing many contradictions. This is a technical problem that has plagued iron and steel enterprises.

介绍 Product introduction


The TK-6000 on-line analysis system for heating value uses the "composition analysis method" instead of the "combustion method" to achieve accurate detection of the heating value of mixed gas.

The “composition analysis method” performs continuous online analysis of the content of combustible gas components in the mixed gas, and then calculates the calorific value through the standard calorific value mathematical model of each gas component according to the standard calorific value of each gas component, thereby realizing the calorific value of the combustible gas. Direct detection. Because the gas composition can be calibrated by a standard gas that conforms to national standards, the standard value transmission is traceable, so it fully meets the national calibration specifications of the metrology department.

TK-6000 on-line analysis system of calorific value of mixed gas is aimed at the characteristics of mixed gas in iron and steel enterprises. It analyzes the gas components H2, CH4 and CO in the gas to calculate the calorific value of the gas, which is suitable for combustion control systems in various occasions. Parameter compensation for heating value.

样气预处理系统 Radon sample gas pretreatment system


Sample gas pretreatment is the key technology of this system. Aiming at the gas containing benzene, naphthalene, tar, water, soot and other conditions, the specially designed flowing water washing and precision filtering technology can effectively treat benzene, naphthalene, tar mist, water, soot and other impurities in the gas.

The sample gas pre-treatment system has advanced sample gas processing technology that guarantees that the analytical instruments achieve online, continuous, and automatic detection under specific working conditions of high temperature, high pressure, dust, and humidity.
