The Dual Adjustable Pulverized Coal Distributor is a core device in power plant boiler pulverizing systems,designed to solve the problem of uneven coal powder distribution.It precisely divides a single coal-air stream into two equal,adjustable outlets,ensuring balanced fuel supply to burners for stable,efficient combustion.Ideal for thermal power,metallurgy,and chemical industries,it is the key to optimizing boiler performance.
Working Principle
It adopts a Y-shaped body with internal adjustable deflectors and splitters.The incoming coal-air mixture is split into two paths.By independently adjusting the coal concentration and airflow control flaps,it achieves dual regulation of both phases.This design ensures equal distribution with deviations≤5%and low resistance(≤500 Pa).
Construction&Materials
Body:Thick carbon steel or stainless steel,pressure-rated for pneumatic conveying.
Wear Protection:Lined with silicon carbide ceramic;durable against high-velocity coal dust abrasion.
Adjustment Mechanism:High-precision flaps with optional electric actuators for remote/automatic control.
Configuration:Vertical or horizontal installation;standard flange connections for easy integration.
Key Advantages
Precise Dual Adjustment:Independently tunes coal concentration and airflow for optimal combustion under variable loads.
Excellent Uniformity:Maintains balance between two outlets,reducing burner heat deviation and NOx formation.
Superior Wear Resistance:Ceramic lining ensures 100,000+hours of reliable operation with minimal maintenance.
Low Pressure Drop:Optimized internal geometry minimizes energy loss,reducing fan power consumption.
Automation Ready:Compatible with PLC/DCS systems for intelligent,closed-loop control.
Technical Specifications
Inlet Diameter:DN200–DN600
Outlet Diameter:DN150–DN500
Distribution Deviation:≤5%(coal&air)
Pressure Drop:≤500 Pa
Material:Carbon steel(ceramic-lined)/Stainless steel
Actuator:Manual/Electric(on-off or modulating)
Applications
Widely used in tangentially fired boilers,wall-fired boilers,and industrial furnaces requiring balanced pulverized coal supply.It is essential for improving combustion efficiency,reducing emissions,and extending boiler service life.
