Deskripsi Analisis Optik
Online Gas Analysis for Industrial Process Control and Energy Monitoring
The online gas analyzer system is widely used in industries where continuous monitoring of combustible gas composition and calorific value is critical.
Aplikasi yang umum meliputi:
Steel plants – monitoring blast furnace gas and converter gas
Coal gasification systems – analyzing synthesis gas composition
Pabrik kimia – process gas monitoring and optimization
Biomass gasification – measuring bio-gas components
Energy efficiency monitoring – evaluating combustion efficiency
Industrial fuel gas monitoring – coke oven gas, mixed gas, producer gas
The analyzer can measure CO, CO₂, CH₄, H₂, hydrocarbons (CnHm), and O₂ concentrations while calculating heating values (MJ/m³ or kcal/m³). Advanced algorithms automatically correct cross-gas interference, ensuring accurate gas composition analysis even when multiple gases coexist.
Its standard 3U rack-mount design with aluminum alloy housing makes it easy to install in industrial control cabinets and monitoring systems.
