Dust extraction systems in combined heat and power plants during the processing of waste wood of various grades. Delivered by truck, the material is conveyed into a feed hopper by means of a push floor unloading system. It is then transported further by huge grabs. These processes generate a considerable amount of dust, which poses a major hazard. Poor visibility due to dust increases the risk of accidents, such as near collisions or tragic collisions between vehicles and workers. In addition, high dust concentrations can impair technical equipment and trigger fire alarm systems, leading to operational interruptions and unnecessary costs.

Advantage: Water mist technology has proven to be an extremely effective method of binding dust.

Effective dust control
Special nozzles spray a fine mist of water directly onto the sources of dust. The mist binds the dust particles, increases their weight, and prevents them from being stirred up. This significantly improves the air quality in the plant and reduces hazardous dust concentrations.

Safe working environment
Lower dust exposure improves visibility and minimizes the risk of accidents for employees. This is particularly important as operating heavy machinery and vehicles in dusty environments can lead to dangerous situations.

Robust design
In this application, the nozzles were installed in sturdy stainless steel housings specially designed for the harsh conditions in combined heat and power plants. A specially manufactured steel armor along the feed hopper protects the spray bars from mechanical damage, such as from grapples, and ensures a long service life for the system.

Efficient use of water
Precise dosing of the water mist achieves effective dust binding without soaking the waste wood. This is crucial for maintaining material quality and plant efficiency.

Optimized system control
Monitoring and control of the system, combined with employee training, ensures the highest safety standards and maximum efficiency. Modern automation technologies make it possible to adjust the mist intensity to the dust load and minimize water consumption.

Prevention of false alarms
A reduced dust concentration prevents false alarms in fire alarm systems, which are often triggered by swirling particles. This contributes to uninterrupted operation and lower maintenance costs.

Conclusion

Dust binding with water mist is an essential solution for combined heat and power plants that process waste wood of various grades. It improves air quality, increases workplace safety, and reduces technical malfunctions. Thanks to its robust construction and targeted application of water mist, long-term operating costs are reduced and plant productivity is increased. In addition, the method helps to create an environmentally friendly and safe working environment—a decisive advantage for modern combined heat and power plants that must meet the highest safety and environmental standards.
