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 1.5 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).

Successful Case

Reutilization of Tail Gas from Zinc Powder Electric Furnace Facili-tates Establishment of National-Level Green Factory

E135 Energy Service Project for Shaanxi Zinc Industry Co., Ltd.

Fuel type Energy Solution Delivery time
Electric furnaces Four E135 gas turbine units March 2023

Utilizing the tail gas from zinc powder electric furnaces as fuel, the electricity generated by the four E135 micro-turbines is integrated into the enterprise’s internal power grid to offset its electricity consumption. The waste heat from the high-temperature exhaust of the gas turbines is used for drying raw materi-als on the production line.

Customer Value:

  • The tail gas from electric furnaces is recovered and consumed via gas turbine The system operates with high efficiency, yields good economic returns, and meets emission standards, Helping clients achieve the accolade of “National-level Green Factory”.
  • Annual power generation reaches 2.94 million kWh, with the heat provided by gas turbine tail gas equivalent to saving approxi-mately 896,297 Nm3 of natural gas.
  • Fully automated operation, eliminating the need to address issues related to manual labor, maintenance, safety inspections, and environmental protection in boiler rooms.
