Notes:[1]Rated operating performance under standard conditions (15℃,101.325 kPa,60%relative humidity).
[2]Derived based on the lower heating value of natural gas at 34 MJ/Nm³(where the standard conditions for Nm³are 0℃and101.325 kPa).
[3]Steamoutput is based on a steam pressure of0.8 MPa(g)and a steam temperature of 175℃ .
[4]Drying heat is based on flue gas heat at temperatures above 120℃.
[5]Hot water output is derived under the conditions of an inlet water temperature of 15℃, an outlet water temperature of 60°℃, and a flue gas outlet temperature of 75℃.[6]Cooling capacity is obtained based on an absorption chiller exhaust gas temperature of 160℃, with a simple cycle COP of 1.5 and a heat recovery cycle COP of 1.0.
[7]Heatng capacity is derived based on an absorption chiller exhaust gas temperature of145℃and aCOPof 0.93.
[8]The energy supply area is calculated based on a cooling load of 40-90 W/m², which is for reference only. Due to variations in the load of different buildings, the actual energy supply area shall be determined according to the specific conditions of the building.
[9]The fuel supply pressure here refers to the pressure required for gas to be supplied directly to the gas turbine (without a compressor) or supplied to the gas turbine after being compressed by a compressor.
[10]This refers to the flue gas volume flow rate under standard conditions(0°℃,101.325 kPa).
