When selecting a burner control cabinet, the core components are primarily determined by the fuel type (gas, oil, or dual-fuel) and the burner's power rating. A compliant, safe control cabinet is customized by matching servo control systems for air dampers and gas valves (such as Siemens industrial combustion control systems) with on-site requirements for explosion-proofing and heat dissipation. Key considerations for selection and configuration include:
1. Core Control Methods: Proportional Modulation (PID Control)—suitable for industrial kilns or boilers with significant load fluctuations and high precision requirements for temperature or pressure; typically paired with servo motors and PLC systems. On/Off or Multi-stage Control—suitable for simple heating equipment with constant loads; offers low cost and simple control logic. Integrated Program Controllers—for small-to-medium burners, standardized burner control units (such as Siemens LMO/LME series or Honeywell series) are used directly, offering safety, reliability, and ease of maintenance.
2. Fuel and Process Matching: Gas Burners—prioritize the configuration of leak detection devices, gas pressure regulating valves, high-voltage ignition transformers, and explosion-proof solenoid valve trains. Oil Burners—require additional controls for oil pumps, oil preheaters (for heavy oil/residual oil), and oil return valve circuits. Special Processes—applications involving synchronized multi-burner control or regenerative combustion require PLC-based logic cabinets to manage complex ignition sequencing and flow-reversal control.
3. Safety and Protection Ratings: Flame Failure Protection—must include a flame detector (UV probe or ionization rod) to ensure fuel cutoff within 1–2 seconds of flame loss. Interlock Protection—the cabinet must provide interfaces for safety interlocks such as air pressure, gas pressure, water temperature/steam pressure limits, and valve position feedback. Protection Rating—if located in dusty or high-temperature workshops, the cabinet requires an IP54 or IP65 rating and must be equipped with a suitable heat exchanger or air conditioner.
4. Brands and Electrical Components: PLC/Controllers—Siemens, Mitsubishi, Omron. Low-voltage electrical appliances: Schneider, CHINT, DELIXI, etc.
