Biomass Combustion Boilers: A Technological Revolution and Application Practice of Green Kinetic Energy

Technological Upgrades: Solving Efficiency and Operation & Maintenance Pain Points

1. Gasification Combustion Technology
   Traditional direct combustion of biomass has problems such as low thermal efficiency and severe coking. The new generation of gasification boilers converts straw, wood chips, etc. into combustible gases such as CO and H₂ through high-temperature anaerobic pyrolysis (>700℃), with a thermal efficiency exceeding 90% and a reduction in tar production of more than 60%, completely solving the problem of furnace blockage.

2. Intelligent Control System
   Integrates IoT sensors and AI algorithms to optimize parameters such as furnace temperature and air supply ratio in real time. For example, after a textile factory in Shandong introduced an intelligent boiler, steam costs decreased by 40% and the failure rate decreased by 70%—the system can predict component wear 3 months in advance, avoiding sudden downtime losses.

3. Fuel Adaptability Upgrade
   For agricultural and forestry wastes with large fluctuations in moisture content, a multi-stage drying-crushing pretreatment system is developed to stabilize the fuel moisture content below 12%. At the same time, the reciprocating grate + secondary air supply design is compatible with various fuels such as straw and rice husks, and the thermal efficiency is stable above 88%.
   In fields such as papermaking and food processing, biomass boilers have also derived a combined heat and power (CHP) model: burning waste to generate electricity, and using the waste heat for drying or disinfection, realizing the cascade utilization of energy and improving the comprehensive energy efficiency by 35%.

4. Future Outlook: Dual Drive of Policy and Technology

   With the mandatory implementation of the "Biomass Boiler Technical Specifications" (2024 edition), equipment emission standards are becoming stricter. Enterprises need to focus on condensing waste heat recovery and co-firing municipal solid waste technologies to further reduce carbon emissions. At the same time, government subsidies (such as environmental protection technology transformation funds) can cover 20%-30% of equipment investment, significantly shortening the payback period.

   Data Verification: The global biomass boiler market size will expand at an annual growth rate of 13.64%, reaching US$13.8 billion in 2026. With the superposition of technological dividends and policy benefits, biomass boilers have been upgraded from an "alternative option" to a "rigid demand for carbon reduction".
