CNG compressor manufacturers take you to understand the calorific value of CNG and filling station
Author:
1. Calorific value of combustion. CNG compressor manufacturers tell you that the combustion calorific value per cubic meter of natural gas is 8000 kcal to 8500 kcal, the density of natural gas is 0.7174kg/Nm, and the combustion calorific value per kilogram of natural gas is 11150 kcal to 11815 kcal. The calorific value of combustion per kilogram of liquefied gas is 11,000 kcal. One cubic meter of natural gas has the same calorific value as one liter of liquefied gas.
2. Gas station. CNG compressor manufacturers tell you that CNG filling station includes parent station, standard station, and substation. The main gas filling station generally takes gas from the high-pressure pipeline to fill the CNG gas cylinder truck, and then supplies gas to the sub-stations through the CNG gas cylinder truck.
CNG compressor manufacturers tell you that the standard station generally takes gas from the urban medium-pressure pipe network to refill CNG vehicles; the sub-stations use CNG cylinder trucks as the gas source to refuel CNG vehicles. The standard station takes gas from the medium-pressure pipe network. Due to its relatively large flow, it has a great impact on the urban medium-pressure pipe network, and at the same time affects the gas supply of other users. Comprehensive consideration should be taken in the selection. Most of them are in the form of sub-stations, which can be divided into conventional sub-stations and hydraulic sub-stations in terms of sub-station types.
The above information is the CNG compressor manufacturer's introduction of the calorific value of CNG and filling station, hope it helps you.
