Eclipse ThermJet Burners for Preheated Combustion Air - Power ...

System Design3DesignDesign structureDesigning a burner system is a straight-forward exercise ofcombining modules that add up to a reliable and safe system.The design process is divided into the following steps:1. Burner model selection:a. The burner size and quantityb. The fuel type and pressurec. The combustor material2. Control methodology3. Ignition system4. Flame monitoring system5. Combustion air system: blower and air pressure switch6. Main gas shut-off valve train selection7. Process temperature control systemStep 1: Burner modelselectionBurner size and quantitySelect the size and number of burners based on the heat balance.For heat balance calculations, refer to the CombustionEngineering Guide (EFE 825).Performance data, dimensions and specifications are given foreach TJPCA model in Data Sheets 206-1 through 206-13Fuel type & fuel pressureThe usable fuel types are:• Natural gas• Propane• ButaneFor other fuels less than 800 Btu/ft (330 MJ/m3) contact Eclipsewith an accurate breakdown of the fuel contents.The minimum gas pressure required at the burner can be foundin ThermJet PCA Data Sheets 206-1 through 206-13.Eclipse ThermJet PCA Design Guide No. 206, 3/5/07
