GE's Aeroderivative Technology Uses Low-Cost Fuel to Help Chinese Steel Producer Increase Efficiency by 15 Percent
- Two of GE’s LM2500+ Aeroderivative Gas Turbines to Replace Current Coke Oven Gas Boiler at HaBei Huafeng Coking Plant in China
- GE’s Technology will Reduce Carbon Dioxide, Sulfur Dioxide and NOx Emissions While Increasing Energy Efficiency and Providing Economic Benefits
HEBEI, CHINA-May 26, 2016-GE (NYSE: GE) announced today that it has signed an agreement to provide HeBei Huafeng Coking Co. Ltd. with two aeroderivative gas turbines to replace the current coke oven gas (COG) boiler at the Huafeng Coking Plant in Hebei, China. The aeroderivative gas turbines will burn 100 percent COG, which will help the coking plant reduce emissions and efficiently convert low-BTU (British thermal unit) gas to power.
Under the terms of the project, GE will supply two of its LM2500+ aeroderivative gas turbines with a standard annular combustor and water injection for NOx control that will utilize COG, a zero-cost byproduct from the coking process, to produce electricity in a cogeneration facility. The current high-emissions, low-efficiency (27 percent) COG boiler will be replaced by GE’s technology and configured in combined-cycle mode with the customer’s existing steam turbine. Once the project is completed, the overall power generation efficiency will be up to 42 percent-an increase of 15 percent-largely enhancing the technology of the Huafeng Coking Plant. This project also takes Huafeng’s COG supply into consideration, leaving enough space to expand production in the future. Commercial operation is expected in the fourth quarter of 2017.
“This project will use a low-cost fuel to provide power for the Chinese public power grid and improve the conditions at the coking plant by reducing emissions and increasing efficiency,” said Yang Dan, general manager, China, GE Power Generation for GE Power. “We’re glad Huafeng chose us based on our proven technology, high quality and service.”
The Huafeng Coking Plant is a service-oriented manufacturing enterprise integrating coking, coal washing, production of chemical products, power generation and coal logistics. It is known as a top 500 private enterprise in China and a large tax contributor in the city where it’s located. Its annual coke production capacity is up to 400 million tons, and the power generation capacity has reached 700 million kilowatt-hours. By selecting GE’s aeroderivative gas turbines, this coking plant will largely reduce carbon dioxide and sulfur dioxide emissions. Its NOx emissions will be under 120 mg/Nm3, which is one-sixth of the current emissions level. While increasing energy efficiency and bringing economic benefits to the enterprise, this project also serves as a demonstration project for other plants in the industry.
