Natural Gas Analyzer – NGCA

Why use a natural gas analyzer?

An industrial natural gas analyzer is essential to ensure stable combustion in industrial environments using gas as the primary energy source.

Variations in gas quality can lead to:

a decrease in energy efficiency
an increase in polluting emissions
an instability of the industrial burners
Continuous analysis therefore makes it possible to anticipate these variations and automatically optimize the settings of the installations.

Measurement of the Wobbe index

W = PCS / √relative density (relative to air)

The Wobbe index is a key indicator of natural gas interchangeability. It allows to compare different gases according to their actual energy delivered during combustion.

Continuous monitoring of this index ensures:

a stable combustion
compatibility between gas sources
a reduction in manual adjustments

Analysis of calorific value

The calorific value (PCI / PCS) represents the energy contained in natural gas.

PCS= E/V

Its measurement makes it possible to optimize:

the efficiency of boilers
fuel consumption
the overall energy performance

Oxidative stress index and combustion stability

The comburity index makes it possible to assess the ability of gas to burn efficiently.

Proper monitoring of this index allows you to:

stabilize the flame
reduce the unburned ones
improve industrial safety
Industrial applications

The NGCA natural gas analyzer is used in:

glass industry
steel industry
industrial ceramics
thermal power plants
gas distribution networks

FAQ – NGCA Natural Gas Analyzer

What is a natural gas analyzer?

A natural gas analyzer is an industrial instrument used to continuously measure the quality of gas used in energy installations. It analyzes essential parameters such as the calorific value, density and composition of gas in order to optimize combustion and equipment performance.

What is the measure of the Wobbe index used for?

The Wobbe index allows for a comparison of the energy quality of different natural gases. It is essential to ensure a stable combustion and avoid performance variations in industrial burners. Its measurement is essential in gas control systems.

What is the difference between lower and higher calorific values?

The net calorific value (NCV) is the energy released without condensation of water vapour, while the gross calorific value (GCV) includes this energy. These two values are essential for optimising the energy efficiency of installations using natural gas.

What is the comburity index in natural gas?

The comburity index measures the gas’s ability to react efficiently during combustion. It optimizes the flame stability, reduces unburned flames and improves the overall performance of industrial systems.

Why use an industrial natural gas analyzer?

An industrial natural gas analyzer allows continuous monitoring of changes in gas quality. It improves fuel efficiency, reduces pollutant emissions and ensures stable combustion in industrial processes.

In which industries is a natural gas analyzer used?

The natural gas analyzer is used in the glass industry, steelmaking, ceramics, thermal power plants and all installations requiring precise control of natural gas and combustion.
