Industrial Energy Efficiency






Kai Chen worked to identify and analyze energy efficiency opportunities for the Huafeng group.


The primary objective of the 2021 EDF Climate Corps Fellowship at Huafeng (China) is to identify and analyze energy efficiency opportunities to be pursued for cost savings and GHG emissions reductions. The energy consumption of the plant comes mainly from two parts: steam heat and electricity. Till now, the energy consumption of the factory is in a relatively extensive pattern, and some work has been done on energy efficiency improvement. We hope to find opportunities and solutions to settle these longtime pain points for the textile industry.


Kai divided his time between these areas:

  • Energy supply and transmission: The boiler thermal energy production efficiency has been found to be problematic after calculation and investigation. In the later period, due to the requirements of the state and enterprises, the use of coal will be gradually reduced and the use of biomass boilers will be investigated. There are defects in the maintenance and use of the air compression system. It has been recommended to check and repair it as soon as possible and establish good maintenance and use rules.
  • Electric energy: In order to improve the use of electric energy, the electric equipment is analyzed and investigated, and improvements are made in three aspects: lighting, motor, and belt drive. It is recommended to use more energy-saving lamps to significantly reduce the use of electrical energy. Regarding the energy efficiency standards of the motors, the management and purchasing departments put forward suggestions to upgrade at the source. Through the use of the old general V-belt, it is found that its transmission energy efficiency has decreased over time, and it is recommended to upgrade to a synchronous belt. Through the improvement of efficiency, power consumption can be reduced and workshop production efficiency is also improved to a certain extent.
  • Heat energy: The temperature in the workshop is higher and the heat loss is more serious. In order to use this part of the heat, it is recommended to install thermal insulation devices for the dyeing machine and valves.

Potential Impact

These projects, when fully implemented, could result in 7,405,510kWh of annual electricity savings, ¥ 7,412,358 NPV of cost savings, and 5,210 metric tons of CO2 emissions reductions.
