湖州首个纯生物质热电联产项目即将正式投产Huzhou's first pure biomass combined heat and power project is about to officially start production

To further comprehensively advance the implementation and effectiveness of the "dual carbon" goals and continuously enhance the level of green and low-carbon development, Huzhou City has, since the beginning of this year, focused on four key areas: "project approval, energy efficiency improvement, coal consumption reduction, and green energy," coordinating efforts to accelerate the transformation of the energy structure. Currently, in Xiaofeng Town, Anji County, the city's first purely biomass combined heat and power project has entered the trial operation stage and is about to officially start production.

The first phase of the Anji Guofeng Combined Heat and Power Project has a total investment of 530 million yuan. The project focuses on the local abundant bamboo resources and processing waste from the bamboo industry. By introducing high-temperature, high-pressure circulating fluidized bed boiler combustion technology, it has overcome the challenges of high moisture content and low calorific value of bamboo waste. Anji County is famously known as the hometown of bamboo, and the waste materials and bamboo shavings generated in bamboo product processing have long faced disposal pressure. Now, these "waste materials" have become fuel for the boilers.

Sun Jian, Deputy General Manager of Production at Anji Guofeng Thermal Power Co., Ltd., a subsidiary of Anji County Investment Group, introduced that the company selected a circulating fluidized bed boiler to match the moisture content and calorific value of bamboo waste. After debugging, the overall thermal efficiency of the circulating fluidized bed boiler can basically reach over 90%; sulfur dioxide emissions are essentially zero, and dust and nitrogen oxide indicators are far below the national ultra-low emission standards. This means that the 'inherent deficiencies' of the fuel are compensated for jointly by the combustion process and end-of-pipe treatment.

Through three biomass circulating fluidized bed boilers and two back-pressure steam turbine generator units, the project converts biomass fuel into green steam and electricity, changing the situation where traditional energy production relies on fossil fuels. Once the project is fully operational, it will effectively reduce the environmental impact caused by bamboo waste accumulation in the surrounding areas, fully realize the green energy substitution of 'replacing coal with bamboo,' and provide stable heat support for the county's industrial park.

The benefit account is equally clear. Jin Yiran, Deputy General Manager of Anji Guofeng Thermal Power Co., Ltd., under Anji County Industrial Investment Group, introduced that according to calorific value calculations, 3 tons of bamboo waste can replace 1 ton of standard coal. The plant can process 140,000 tons of bamboo waste annually, replacing about 46,000 tons of standard coal, and reducing carbon dioxide emissions by about 120,000 tons per year. On one hand, this can effectively dispose of bamboo waste generated by the local bamboo industry and reduce waste production; on the other hand, it also supports the development of clean energy in the county.

Since the beginning of this year, Anji County has been thoroughly implementing the "dual carbon" work deployment, focusing on key areas to continuously deepen the green and low-carbon transition, and accelerating the construction of a clean, low-carbon, safe, and efficient energy system. By learning from the successful experience of the Guofeng cogeneration project, Anji County is actively planning to build a new type of energy system that covers the entire region, further optimizing the energy supply structure. Zhao Wenlin, head of the Energy Division of the Anji County Development and Reform Bureau, stated that the next steps will focus on piloting photovoltaic projects across the county, completing photovoltaic installed capacity grid connection of more than 421,000 kilowatts within three years, steadily promoting the green transformation of energy, consolidating the construction of a new county-level energy system, and driving carbon reduction in production and life through energy structure transformation, striving to create a model of county-level green transformation guided by the concept that lucid waters and lush mountains are invaluable assets.
