Automatic burner control system BCS 300 Dungs for oil and gas

Automatic burner control BCS 300 Dungs
  • These automatic burner controls BCS 300 are a system for open and closed loop control of oil, gas and dual-fuel burners with medium to high output. It consists of multiple distributed units which intercommunicate via a safety-oriented bus system:
- Flame monitoring device that can incorporate various flame sensors: ionization, UV, photoresistor, 2 contact inputs.
- Hand-held programmer that has a 4 line LCD on which information on the status of the burner control system can be displayed. Password-protected for parameters changing.
- Actuator SAD 15.
- Remote control via internet on the FTP server.
  • The BCS-300 can be connected by means of different gateways to superordinate control systems or other external control and surveillance systems.
  • Six different applications programs can be selected depending on required application: operation with pilot valve upstream of the safety valve and the main valve; operation with pilot valve between the safety valve and the main valve; operation with or without valve proving system, with or without pilot valve.
  • Integrated controller that responds to a signal from 4 to 20 mA.
  • Integrated valve proving system with an additional pressure switch.
  • Note: This series is no longer part of the Dungs main product line.

BCS-EM1 for O2 control

O2 probe is fail-safe and suitable for continuous duty in combination with the BCS System. No reference gas required. Long service life of the probe (>2 years). The control parameters can be switched on and off separately for each fuel type. Simple regulation at burner start-up. Continuous digital display of O2 measured value and O2 optimization status.

 

Control BCS-EM1 O2

 

Advantages for the operation of a system with O2 control (optimization):
- The O2 exhaust gas measuring probe is fail-safe and suitable for continuous duty in combination with the BCS System.
- The optimization function adjusts the O2 value specific to burner capacity and without a limiting curve, until the reference value equals the actual value.
- Manipulated variable adjustment is only limited by the range limits of the actuator but not by prescribed limit bands.
- The probe requires no reference gas.
- Weather-related interference is compensated, thereby achieving an improvement in burner efficiency.
- Incomplete combustion due to effects of temperature is impossible.
- Fuel consumption is reduced as the burner can be regulated with significantly less excess air.


BCS-EM1 for speed control

Control BCS-EM1 speed
Advantages for the operation of a system with speed control:
- Reduction of sound emission (no sound insulation is required in some cases).
- Speed supervision in every load range.
- Considerable savings in electrical energy (up to a factor of 0.5).
- The control range of the burner is extended by precise adaptation of the combustion air to the burner control system.
- Soft starting greatly reduces mechanical stress on the motor and fan impeller
- Simplification and improvement of air-side burner adjustment.
- Improved adaptability of the burner within its operating area of the existing system constellation.
