| Serial number | User Unit | Furnace type | Number of coke ovens | Coke oven output | Project scale | Project Type | Signing Date | Time of commissioning | Product |
| 1 | Qinghua Coal Chemical Co., Ltd., Qinghua Group, Inner Mongolia | 5.5 meters | 2x55 holes | 1.1 million tons | 140t/h | EMC | 2022.05 | 2022.10 |
The product generates superheated steam at 4.5 MPa and 450°C, with a steam production rate of approximately 500–560 kg per ton of coke. |
| 2 | Ningxia Qinghua Coal Chemical Group Co., Ltd. | 5.5 meters | 2x55 holes | 1.1 million tons | 140t/h | EMC | 2022.06 | 2023.12 |
Superheated steam at 9.8 MPa and 540°C is generated and fed into Party A’s steam network, with a steam production rate of approximately 500–560 kg per ton of coke. |
| 3 | Ningxia Qinghua Coal Chemical Group Co., Ltd. | 5.5 meters | 2x55 holes | 1.1 million tons | 140t/h | EMC | 2022.06 | 2024.06 |
Superheated steam at 9.8 MPa and 540°C is generated for power generation, with a steam production rate of approximately 500–560 kg per ton of coke. |
| 4 | Qinghua Coal Chemical Co., Ltd., Qinghua Group, Inner Mongolia | 6.78 meters | 2x70 holes | 2 million tons | 260t/h | EMC | 2022.12 | 2024.06 |
The superheated steam, with a pressure of 9.8 MPa and a temperature of 540°C, is routed into Party A’s steam network after passing through the back-pressure turbine unit, yielding a steam production rate of approximately 500–560 kg per ton of coke. |
| 5 | Zhangye Jinchangyuan Coal Industry Co., Ltd. | 6.25 meters | 2x52 holes | 1.2 million tons | 150t/h | EMC | 2025.12 | Construction Phase | Superheated steam at 9.8 MPa and 540°C is used to generate electricity in an extraction‑condensing turbine‑generator unit, with a steam production rate of approximately 500–560 kg per ton of coke. The extracted steam is supplied externally at an absolute pressure of 0.9 MPa and a temperature of 240°C ± 10°C, or as saturated steam. |
