Fixed Grate Structure Enhances Combustion Stability
During the operation of a biomass boiler, the stability of the combustion system directly affects steam output and fuel utilization efficiency.
The EPCB fixed grate boiler is optimized for the combustion characteristics of biomass fuel:
· The furnace space is more rational.
· Higher flame density
· The combustion structure is more uniform
· More stable heat release
By optimizing the furnace structure and the layout of the heating surfaces, the boiler can effectively improve its thermal efficiency and maintain a continuous and stable steam output.
Even under long-term high-load operation, the system can still maintain good combustion stability.
This is especially important for textile companies to maintain continuous production.
Advanced Fixed Grate Structure Ensures Stable Biomass Combustion
EPCB firmly believes that a stable boiler system depends not only on the boiler itself, but also on the rationality of the entire system configuration.
Therefore, in this project, EPCB provided the customer with a complete auxiliary system solution.
High-Efficiency Forced and Induced Draft Fan System
The boiler is equipped with a high-efficiency blower and induced draft fan system.
The blower can continuously provide a stable air supply to the furnace, ensuring complete combustion of fuel.
The induced draft fan can maintain a stable negative pressure in the furnace.
· Ensure smooth exhaust of flue gas
· Improve combustion stability
· Improve boiler operating conditions
· Reduce the risk of flue gas retention
The two fan systems work together to effectively improve the overall combustion efficiency.
Intelligent Electrical Control System Enhances Automation Performance

Advanced Dust Removal System Ensures Environmental Compliance
With Bangladesh's increasingly stringent environmental requirements, customers are paying particular attention to flue gas emission control.
Therefore, EPCB designed a multi-stage flue gas dust removal solution for this project.
Multi-tube dust collector reduces system load
The flue gas first enters the multi-tube dust collector.
This system can effectively separate large dust particles from flue gas:
· Reduce the operating load of downstream environmental protection equipment
· Improve overall dust removal efficiency
· Extend the service life of bag filters
Multi-tube dust collectors are stable in structure, resistant to high temperatures, and easy to maintain, making them particularly suitable for biomass boiler operation.
Baghouse dust collectors have gained high recognition from customers.
