Home Portfolio Kiln burner upgrades
The burner system is an important and integral component of a rotary kiln system to optimize the combustion of fuels to release heat in the kiln.
  • Optimized fuel combustion
  • Increased safety
  • Energy efficient
  • Reduced maintenance costs
  • Lower environmental impact
  • Multi-fuel capability designed to handle gas, oil, pulverized coal, petroleum coke, or non-condensable gases separately or in combination are available
  • Flame is directional adjustable, and flame shape control is obtained by dual air channels
  • Low primary air design to maximize fuel efficiency and energy recovery from auxiliary cooling devices
  • Mechanical or steam atomization of oil and sturdy, rugged construction for high-temperature duty
  • Burner systems range from preheating to 300 MBtu/hr. (315 GJ/hr.)

Engineered for specific job requirements

All burner systems are designed based on Metso Outotec’s vast burner experience and system process design.  When designing a burner system, our engineers consider the requirements of the process to optimize the burner design to match the requirements of the process. Each system is designed using Metso Outotec proven proprietary burner designs as the basis. CFD modeling is used to help analyze and validate the
burner design to match the process requirements.

State-of-the-art burner systems

Engineered and custom-designed valve trains

Valve skids are engineered and designed to meet the operator's specific local requirements, including fuels, standards, preferred suppliers, and space constraints.

Engineered pump and heater sets for heavy oil service or light oil duty, in simplex or duplex models, are available.


Burner management systems (BMS)

  • Flame safeguard, and burner management systems are designed specifically for applications to rotary kilns firing gas, oil, or solid fuels.
  • Programmable Logic Controlled (PLC) systems perform all required limit checking and operator input checking during burner light-off.
  • Alpha-numerical message display on local flame safeguard panel guides operators through burner start-
    up procedure.
  • Remote start/stop capabilities can be provided to the plant Distributed Control System (DCS).
  • Systems provide increased diagnostics and ease of operation, flexibility, and space savings.
  • Systems conform to recognized international standards including EN and FM.


Maximum flame shape and location control for optimum kiln performance

Based on the system design experience and field experience of Metso engineers, the critical factors of flame shape and location to complement kiln internals are applied to the burner design.

Burner design features include single or dual primary air paths, dual (axial and radial) natural gas paths, easily changeable fuel oil nozzle, adjustable fuel nozzle to primary air nozzle relationship, and easily adjustable burner mount and primary airflow.
