Grid type duct burners

Our 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.
