The Plate Type Coal Powder Mixer is a high-efficiency,low-energy continuous mixing device specially developed for thermal power plants,coal chemical plants,and industrial boiler systems.It is used to mix pulverized coal with air,flue gas,or additives uniformly,ensuring stable combustion,reducing NOₓemissions,and improving boiler efficiency.
Construction&Materials
Body:Carbon steel or stainless steel(SS304/316L),pressure-resistant and wear-resistant.
Mixing Plates:Multiple layers of inclined or perforated plates inside,arranged in a staggered pattern to create strong turbulence.
Shaft&Drive:Heavy-duty shaft with gear motor,low speed and high torque,stable operation.
Sealing:Mechanical seal+packing gland,prevents powder leakage.
Working Principle
Raw coal powder enters the mixing chamber from the top inlet.As it falls,the staggered plates repeatedly split,disperse,and recombine the powder flow.High-speed primary air carries the powder through the plate gaps,forming a swirling turbulent field.This 3D mixing action ensures coal powder and gas are blended into a homogeneous gas-solid mixture before entering the burner.
Key Features
Uniform Mixing:No dead zones;mixing efficiency≥90%,improves combustion stability.
Wear Resistance:Hardened plates extend service life;easy to replace worn plates.
Low Pressure Drop:Optimized plate angle reduces resistance,saves fan energy.
Dust-tight Design:Fully enclosed structure,no powder spillage,clean operation.
Easy Maintenance:Modular design,quick access for inspection and cleaning.
Customizable:Plate number,angle,and material can be adjusted for different coal types.
Technical Advantages Over Ordinary Mixers
Compared with ribbon or paddle mixers,the plate type has higher mixing efficiency and lower power consumption.
The layered plate structure avoids material short-circuiting,ensuring consistent mixing quality.
Compact size,easy to install in limited boiler space.
Applications
Thermal power plant boiler pulverizing&combustion systems
Industrial coal-fired boilers and furnaces
Coal gasification and coal slurry preparation lines
Flue gas desulfurization powder mixing systems
