WebFuel enters the HRSG at a much lower temperature (40F is typical) than the nominal 1000F TEG temperature at the duct-burner inlet. Thus, the fuel heats up as it flows along the duct-burner element. Heat-transfer calculations made by HRST engineers predict the fuel temperature curve in Fig 6 for a typical duct burner. WebMar 1, 2024 · At an exhaust temperature of 788°F (420°C), for example, superheated steam at about 145 psig (11 bar) and 715°F (380°C) can be generated, allowing for a thermally … WebDec 25, 2024 · This firing reduces HRSG efficiency. In peaking plants, the steam generation is double in 5 to 10 minutes. Duct burner can be added to account for CTG and HRSG degradation. Firing Temperature: Low ≤ 1250°F. Medium ≤ 1450°F. High - 1450°F to 1600°F. In natural gas combustion, flame length is 6’ to 8’ and firing chamber length is 14 ... farming tourism
