SYSTEM FOR MEASURING HEAT CAPACITY OF NATIONAL GAS

摘要

The present invention relates to a system for measuring the heat capacity of natural gas capable of measuring the heat capacity of gas supplied from the gas inlet of combustion devices in real time, calculating data using the Wobbe index (WI), and automatically controlling the combustion devices with the required heat capacity using the calculated data. The present invention comprises a WI measurement and control unit (100) installed in the front end of the gas inlet to measure the heat capacity of the gas supplied to the multiple combustion devices and to control the combustion devices based on the measured data. The WI measurement and control unit (100) detects the temperature, pressure, and mass flow values of sample gas (110) and reference gas (120) and compares them to calculate the required heat capacity, thereby controlling the combustion devices. The heat capacity is calculated using WI.
