Grid Type Duct Burners

Our (De Jong Combustion) grid type duct burner is gas-fired and designed for supplementary firing in exhaust gasses from a gas turbine, gas or diesel engine or other industry process flow. Its main function is to increase the temperature and consequently the steam output of a Heat Recovery Steam Generator (HRSG) or Waste Heat Recovery Unit (WRHU). This burner satisfies the need for variable steam demand e.g. between seasons of the year, between periods of the day (for peak shaving purposes) or between stages of the process. 

Modular design: The grid type burner is of modular design which can be adapted to each specific application.

Low maintenance cost: The grid type burner design, which is made up of heavy casted stainless steel flame stabilizers and high-grade stainless steel construction, is very robust and assures a long lifetime of the burner without requiring any maintenance.

Low emissions, high stability: The special shape of the burner wings assures stable combustion over the total operating range resulting in low emissions of NOx, CO and UHC’s.

Fuel flexibility: Grid type duct burners operate on a broad range of fuels ranging from fuels containing hydrogen to fuels containing heavies or olefins.

Fresh air firing: Grid type duct burners can be used as a backup system to continue HRSG operation when the turbine is stopped. In that case, fresh air from combustion air fans is routed to the duct.

Circular Type Duct Burners

Our circular type (R&V) duct burner is gas and/or oil fired and designed for supplementary firing in exhaust gases from a gas turbine, gas or diesel engine or other industry process flow. Its main function is to increase the temperature and consequently the steam output of a Heat Recovery Steam Generator (HRSG) or Waste Heat Recovery Unit (WRHU). This burner satisfies the need for variable steam demand e.g. between seasons of the year, between periods of the day (for peak shaving purposes) or between stages of the process. 

Low maintenance cost: The circular type burner design, which is made up of stainless steel internals, stabilizers and high-grade stainless steel construction, is very robust and assures a long lifetime of the burner without requiring any maintenance.

Low emissions, high stability: The special shape of the burner throat and duct assures optimum stable combustion over the total range resulting in low emissions of NOx, CO and UHC’s.

Multiple fuels: The circular duct burner can accommodate several different fuel types by installing dedicated fuel headers and nozzles.

Fresh air firing: Circular type duct burners can be used as a backup system to continue HRSG operation when the turbine is stopped. In that case, fresh air from combustion air fans is routed to the duct.

Low NOx Register Burners

Our register burners fired on fuel gas and/or fuel oil are typically applied in direct-fired boilers.

Low emissions, high stability: In order to minimize NOx emissions, the burners make use of various proven techniques as combustion air staging, fuel staging, internal flue gas recirculation which have been fine-tuned during several projects. A stable flame is created with consequential low Carbon Monoxide and UHC emissions.

Multiple fuels: The register burners can accommodate several different fuel types by installing dedicated fuel headers and nozzles.

Tuning: In order to optimize the burner flames regarding emissions and flame shape, during commissioning, the orientation of the gas spuds, the annulus/core air ratio and the swirl (if applicable) of the annulus air flow can be adjusted.

CO Combustors / Incinerators / Oxidizers

The purpose of an incinerator is to deplete the harmful components from a process waste stream by oxidation as it cannot be emitted to the atmosphere or used as ordinary fuels. Often, the waste stream is Carbon Monoxide and in that case, the Incinerator is called CO-combustor.

An Incinerator consists of a refractory lined vessel with one or several special conventional burners with injectors for the to incinerate gasses. The vessel creates the required residence time whereas the burner(s) create(s) the high-temperature environment. Further, the waste gas needs to be mixed with a certain flowrate of the oxidation gas, air.

The latter process is the crucial aspect of the incinerator and is determining for its performance. At the effluent of the incinerator a HRSG is located which produces steam.

Auxiliary Equipment

For a reliable and functional combustion system we obviously are specialists in the following auxiliary systems:

  • Fuel gas and Fuel Oil skids
  • Gas pressure reduction stations
  • Heavy Oil booster pump and heater skids
  • Cooling air and auxiliary air skids
  • Burner Management Systems (BMS). Supporting any type of PLC hardware: Siemens, Allen Bradley, Honeywell, Hima
