Combustion Control System (BMS): Used for safety monitoring of various heating equipment, including furnaces, boilers, ovens, preheaters, reactors, calcining furnaces, dryers, thermal oxidizers, rotary kilns, furnaces, incinerators, process heaters, and vaporizers.

Emergency Shutdown System (ESD): Automatically places the factory in a safe state upon detecting dangerous situations.

Fire and Gas Monitoring: Real-time monitoring of fire risks and harmful gas leaks in the environment.

Pipeline Monitoring: Integrity monitoring of oil and gas transportation pipelines.

Overflow Prevention: Prevention of liquid overflow in storage tanks or during processes.

Tunnel Ventilation: Emergency control for tunnel safety and ventilation in subways and highways, ensuring traffic safety.

2. Process Control and Optimization Applications

Combustion Control: Optimizing fuel/air ratio to improve combustion efficiency.

Pressure and Flow Control: Maintaining process parameters stable through PID and advanced algorithms.

Heat Treatment:

Carbon Potential Control: Monitoring furnace temperature and probe output, controlling the carbon potential inside the furnace based on zirconium probe input, and including anti-carbon accumulation function.

Dew Point Control: For equipment such as heat-absorbing atmosphere generators, calculating dew point through oxygen sensors.

Terminal Automation: Automation management of oil depots, logistics terminals, etc.

Wastewater Treatment: Automated control of wastewater treatment processes.

3. Batch and Formula Management

Batch Production: In industries such as food and beverage, pharmaceuticals, etc., using the formula function to ensure extremely low error rates for product/process switching.

Setpoint Program: Automatically controlling setpoints for PID loops, creating time/value curves for batch process control.

Sequence Control: Controlling process operation sequences based on time or process events.

4. Data Acquisition and System Integration

OPC Data Integration: Transmitting real-time data to historical databases, HMI (Human Machine Interface), and SCADA (Supervisory Control and Data Acquisition) systems through MatrikonOPC server.

Experion System Integration: Seamless integration with Honeywell Experion PKS/LX/HS system to achieve historical data backfilling and meet the needs of critical data applications (such as pharmaceuticals). Remote Monitoring: Utilizing the embedded Web server functionality, it enables access to the application from anywhere.

5. Industry-specific compliance cases

AMS 2750E Compliance: Meets the key requirements for instrument control, monitoring, and recording in aerospace material specifications (calibration accuracy ±1.1°C/±2°F).

In summary, Honeywell ControlEdge HC900 is a hybrid control system that combines high security, flexible scalability, and ease of use, effectively covering a wide range of needs from single equipment control to full plant integration.
