Natural gas calorific value analyzerCalculate the calorific value by measuring the heat released from natural gas combustion or analyzing the concentration of gas components.
Natural gas calorific value analyzerWorking principle:
Combustion heat effect method: Introduce natural gas samples into the combustion chamber, mix them with oxygen and ignite them. Measure the heat generated by combustion through heat sensors (such as thermocouples, thermistors, etc.), and then calculate the calorific value of natural gas based on the heat.
Gas chromatography method: using chromatographic columns to separate various components in natural gas, such as methane, ethane, etc., then quantitatively analyzing them through detectors (such as FID, TCD), and finally calculating the total calorific value based on the contribution of each component's calorific value.
Infrared spectroscopy: Based on the absorption characteristics of different gases towards specific wavelengths of infrared light, the concentration of methane and other components in natural gas is measured, and then converted into calorific value.
Technical characteristics:
Accurate measurement: Using high-precision temperature, pressure, and flow sensors, combined with advanced measurement principles, some instruments can achieve measurement accuracy within ± 0.5%, and also have automatic calibration and correction functions.
Quick analysis: The efficient combustion system enables natural gas to burn quickly, and high-performance microprocessors and data processing software can complete the entire process from sample collection to calorific value result display within 10-30 minutes.
Wide measurement range and strong adaptability: It can adapt to the measurement of calorific value of different types of natural gas, with a measurement range usually between tens of megajoules/cubic meter and hundreds of megajoules/cubic meter, and can work normally within a wide range of pressure, flow rate, temperature, and humidity.
High degree of automation and intelligence: Equipped with automatic sampling and injection functions, it can achieve intelligent operation and control through various methods, and can also store and transmit data.
