Abstract Scope In Natural gas pressure reduction stations, gas with temperature 15 C enters to station, as the gas pressure drops, temperature drops too, this can cause condensation or frosting gas compounds, resulting block in flow path. To avoid this phenomenon, station inlet should be pre-heated before going to regulators and pressure reduction process, using heaters installed in station; much of heat from burning gas is transferred to environment through body and specially stack. this article tries to calculate amount of wasted energy using experimental results of field research and data collection from a sample heater of gas pressure reducing station, by numerical modeling of the stack in Ansys software. modeling and analyzing the results determined daily 3.46Kwh energy as heat from body and 55.2Kwh energy output from stack to environment is wasted, considering the heater’s functions annually and many of these heaters in whole country, considerable energy source can be retrieved.
