Jufeng Thermal Focuses on Biomass and Carbon Capture Technologies, Leading Industrial Combustion Toward a "Carbon-Negative" Future

Recently, a study published in the top international academic journal Engineering highlighted that Staged, Pressurized Oxy-Combustion (SPOC) technology can retrofit existing coal-fired boilers to fire woody biomass, achieving over 95% carbon capture efficiency and delivering carbon‑negative emissions. As a national high-tech enterprise specializing in high-efficiency, energy‑saving, and environmentally friendly combustion technologies, Jiangsu Jufeng Thermal Technology Co., Ltd. (hereinafter “Jufeng Thermal”) has long been deeply engaged in the industrial combustion and thermal energy sector. The company closely monitors and actively positions itself in the important technology pathway of Bioenergy with Carbon Capture, Utilization, and Storage (BECCS/BECCU).

SPOC Technology: An Ideal Combination of Biomass Combustion and Carbon Capture

Since its inception in 2012, SPOC technology has integrated fuel staging with pressurized oxy‑combustion to achieve a more compact plant layout, higher energy efficiency, and lower costs for pollutant and greenhouse gas removal. Originally designed for coal, the research shows that SPOC is particularly suitable for biomass combustion—because biomass flue gas has a high moisture content, and SPOC can recover the latent heat of this water vapour, thus improving overall system performance compared to conventional atmospheric biomass combustion systems.

In terms of system efficiency, the study indicates that compared to a reference power plant with post-combustion carbon capture (PCC), the SPOC power plant is 33% more efficient, and the SPOC combined heat and power (CHP) plant has 42% higher net energy output. At the experimental level, a research team at Washington University in St. Louis has successfully conducted 100% biomass combustion tests in a 100 kWth pressurized oxy-combustor, demonstrating excellent performance in start‑up, steady-state operation, and load regulation.

Carbon Capture Efficiency Exceeds 95%, Supporting Deep Industrial Decarbonisation

The most remarkable advantage of SPOC technology lies in its carbon capture capability. Because the entire process operates under pressure, the CO₂stream can be directly compressed and sequestered with lower energy consumption. The integrated system includes an air separation unit, a staged pressurized boiler, high-temperature heat recovery, a baghouse filter, a direct contact cooler (DCC), and a CO₂ processing unit. The DCC simultaneously performs flue gas cooling, water vapour condensation, and removal of SOₓ, NOₓ, and HCl in a single pressurised tower, significantly reducing capital and operating expenditures compared to conventional flue gas treatment systems

The research confirms that retrofitting existing coal-fired boilers with SPOC technology can convert them into carbon-negative assets using sustainable woody biomass, offering a practical pathway for industrial decarbonisation and repurposing thermal assets.

Jufeng Thermal: Core Combustion Expertise Embracing a Green Energy Future

Founded in 2015 and headquartered in Yangzhou, Jiangsu Province, Jufeng Thermal is a national high-tech enterprise with a strong focus on efficient, energy-saving, and environmentally friendly combustion technologies. The company has developed proprietary core technologies, including fuel oil secondary atomisation, heavy oil flat-flame combustion, low-NOx combustion, and oxygen-enriched and pure-oxygen combustion. Its self-developed burners, nozzles, and oil guns cover 15 product series and over 200 specifications, compatible with a wide range of fuels including oil, gas, coal, and biomass.

In 2025, Jufeng Thermal expanded its business to include biomass formed-fuel sales and biomass energy technical services, and has filed patent applications such as “A flue gas filtration device and method for biomass burners”. These initiatives mark the company’s accelerated technology reserve and market development in the biomass energy sector.

Looking Ahead

As China’s “dual carbon” goals advance, the demand for low-carbon and even carbon-negative combustion technologies in the industrial sector is becoming increasingly urgent. Pioneering technologies such as SPOC, which combine biomass combustion with carbon capture, offer a fresh approach to the green retrofitting of existing industrial boilers. Jufeng Thermal will continue to leverage its technical strengths in oxygen-enriched combustion, low-NOx combustion, and biomass combustion, actively exploring the industrial application of biomass-carbon capture integration. The company is committed to providing customers with more efficient, energy‑saving, and environmentally sustainable combustion and thermal energy solutions, contributing to China’s green and low-carbon industrial transformation.
