Boiler Combustion Calorific Value Detector

Boiler Combustion Calorific Value Detector

Fuel gas is a mixture of various gases, with combustible components primarily including hydrogen, carbon monoxide, methane, hydrogen sulfide, and various hydrocarbons, while non-combustible gases mainly consist of carbon dioxide, nitrogen, and water vapor. According to the classification by the International Gas Union (IGU), fuel gases can be categorized as follows:

Wobbe Index Classification

Class I gas: Wobbe Index between 17.8 and 35.8. Online Analyzer for Biomass Pyrolysis Process Products

Class II gas: Wobbe Index between 35.8 and 53.7. L: Wobbe Index between 51.7 and 53.8. H group: Wobbe Index between 51.6 and 53.7.

Class III gas: Wobbe Index between 71.5 and 87.2.

Fuel gas is classified into three categories based on calorific value:

High calorific value gas: Calorific value greater than 15.7×10^6 J/Nm³.

Medium calorific value gas: Calorific value between (6.28–15.07)×10^6 J/Nm³.

Low calorific value gas: Calorific value below 6.28×10^6 J/Nm³.

Boiler Combustion Calorific Value Detector Product Performance Advantages:

● Fully automated one-click start system (automatic sampling, automatic collection, automatic display of analysis results, no manual intervention), simple operation.

● The instrument automatically applies bridge current upon startup, eliminating the need for manual operation.
