Industrial burner systems

Combination burner system BCB

Combined oparation: combustion of dust, oil and gas

The combination burner system BCB (sometimes also called multi-fuel burner) from Büttner  functions as a flue gas generator for diverse industrial processes. These burners are commonly used to heat drum dryers.
Büttner‘s combination burners are capable all-rounders and burn sander dust, screen dust and gaseous or liquid fuels. 
Büttner‘s combination burners make reliable, profitable and low-emission facility operations possible thanks to a flexible mix of combustion methods. Büttner‘s burner systems are each specially designed to meet the demands of the individual customer.

Details

Depending on the design, the burners have a gas train, an oil pump and metering station, as well as a dust metering and conveyor station. The entire operation is fully automatic, including adjustments to the optimal air-fuel ratio, and regulated electronically depending on the load requirement.
The entire system, including all main and auxiliary units and all components for the feeding, regulation, and metering of fuel, meet the most current technical safety requirements. In particular, this concerns the flame monitoring system, which employs type-tested compact flame detectors.

THE MECHANICS OF OUR COMBINATION BURNERS:

  • Ring gap for dust output, an even distribution of dust thanks to Büttner‘s patented rectifier unit.
  • Phased air flow and adjustment options for primary and swirl air – the length and width of the flame can be adjusted depending on dust quality and the dimensions of the combustion chamber.
  • Dust metering without cleaning interval.
  • BÜTTNER BDFS type dust feed with multiple metering screws for a uniform material discharge.
  • Gas train and safety systems, completely installed, wired and tested to ensure no leaks are present.
  • Oil-pump and -metering station completely pre-installed in a frame rack with oil tray.

CONTROLLING OUR COMBINATION BURNERS

  • The combustion air volume is measured and displayed in Nm³ (pressure and temperature correction).
  • Automatic recording of the combustion air volume and conversion to the standard state for the purposes of lambda control.
  • Unlimited number of adjustment curves – to ensure that varying fuels and conditions at the facility can be addressed.
  • Controlled by means of a PLC with display (no black boxes).
  • Minimisation of production downtimes: if dust is unavailable, the burner automatically switches to operate from gas or oil.
