Notes:
[1] Rated operating performance under standard conditions (15°C, 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 Nm3 are 0°C and 101.325 kPa).
[3] Steam output is based on a steam pressure of 0.8 MPa(g) and a steam temperature of 175°C.
[4] Drying heat is based on flue gas heat at temperatures above 120°C.
[5] Hot water output is derived under the conditions of an inlet water temperature of 15°C, an outlet water temperature of 60°C, and a flue gas outlet temperature of 75°C.
[6] Cooling capacity is obtained based on an absorption chiller exhaust gas temperature of 160°C, with a simple cycle COP of LS and a heat recovery cycle COP of 1.0.
[7] Heating capacity is derived based on an absorption chiller exhaust gas temperature of 145°C and a COP of 0.93.
[8] 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°C, 101.325 kPa).

| Fuel Gas in Coal Chemical Industry | One E2100 gas turbine+ 12-ton flue gas waste heat boiler system | June 2023 |
During the production process, the project generates a large amount of fuel waste gas with a calorific value of approximately 7.4 MJ/kg. A small gas turbine is used for combined heat and power recovery and utilization of the vented fuel gas, realizing cascaded energy utilization. This provides part of the electricity and steam required for the plant’s production, while addressing environmental protection issues and heat-electricity demands.
