Abstract:
A method for measuring the component and calorific value of goal gas. The method includes measuring a volume concentration of H2 (TH2) using a thermal conductivity detector (TCD), measuring a volume concentration of O2 using an electrochemical detector (ECD), measuring volume concentrations of CO, CO2, CH4, and CnHm in the coal gas, revising an interference of CH4 in CnHm, revising a measured volume concentration of H2, and calculating the calorific value of the coal gas.
