1. Real-time online soot blowing/cleaning
   How does a ZOZEN biomass boiler improve fuel combustion efficiency? ZOZEN’s three-drum biomass boiler supports real-time online cleaning without shutdown. This technology enables stable year-round operation, adding about 15–30 extra days of output. It ensures continuous production while reducing economic losses from shutdowns for cleaning.

2. Higher thermal efficiency
   How does a ZOZEN biomass boiler improve fuel combustion efficiency? In actual operation, ZOZEN biomass boilers improve thermal efficiency by about 10% compared with conventional boilers. For a 20 t/h unit running 6,500 hours annually, a 10% efficiency gain can save about USD 280,000 in fuel costs. This significant energy-saving effect demonstrates ZOZEN’s strength in boosting combustion efficiency.

3. Strong fuel adaptability
   How does a ZOZEN biomass boiler improve fuel combustion efficiency? The three-drum biomass boiler offers strong fuel adaptability and can be customized to fuel properties such as calorific value and volatiles. Supported fuels include biomass pellets, wood chips, sawdust, demolition crushed material, rice husks, and more. This flexibility maintains high combustion efficiency under varying operating conditions.

4. High degree of automation
   How does a ZOZEN biomass boiler improve fuel combustion efficiency? ZOZEN biomass boilers feature automatic feeding, automatic soot blowing, and automatic ash discharge, greatly reducing labor costs. High automation enhances operational stability and reduces safety risks from manual intervention.

5. High-temperature-resistant materials
   How does a ZOZEN biomass boiler improve fuel combustion efficiency? The boiler uses grate bars rated for high temperatures (about 1160°C), featuring low failure rates and high reliability, ensuring long service life. This design lowers maintenance costs and minimizes downtime due to equipment failures.

6. Customized air distribution and control system
   How does a ZOZEN biomass boiler improve fuel combustion efficiency? The three-drum biomass boiler is equipped with customized air distribution and a control system that prevents grate damage during operation, ensuring safe, stable, and reliable performance.
