New Design FD Fans for Boilers

According to Daily Mail reported, Bob Thissen, a photographer based in Netherlands, took the pictures of abandoned power plant inner scene, which is located in Philadelphia, America.

Since the power plant shut down 30 years ago, many film makers were attracted to this place by its reputation as a scenic location, and many movies were shooted in this rusting power plant, such as Transformers, Twelve Monkeys, The Last Airbender by M. Night Shyamalan.

The Reason of Centrifugal Fan Impeller Ash Deposition

The main reason of the centrifugal fan impeller ash deposition is that, when the waste exhaust flow through the impeller, a large number of fine dust particles collide with impeller non-working surface and blade trailing edge near the working face in impeller, then deposite in the centrifugal fan impeller; what's more, dust particles are more sticky under high temperature, so the deposition chance increase. 

High Temperature Fan for Cement Rotary Kilns

Thus, the waste exhaust gas temperature and airflow speed play an important role in the ash deposition process, when the exhaust temperature of the cement kiln preheater reach over 300 centigrade degrees, then high temperature centrifugal fan will begin to happen dust deposition and crust frequently.

5. Seal Fan: The air is from cold primary air, the seal fan sending to coal machinery and coal mill; as for the coal mill, the sealing air is used in grinding roller, roller bowl mill, spring loaded and other parts.

6. Boost Fan: One part air enters into boost fan from ID Fan, the other part air enters into chimney by-pass. The by-pass is not allowed to open during the power unit working, otherwise, the smoke air without desulfurization environmental protection can not reach up to standard. 

Stainless Steel Material High Corrosive Fan

The air from boost fan will enter into gas desulfurization system, in the simulation of flue gas desulfurization and denitrification system of large-scale thermal power station, boost fan is the core of flue gas system.

3. ID Fan: ID fan exhausts smoke from boilers, to maintain the boilers negative pressure. The smoke go through the air preheater, after dust collecting, then enter into gas desulfurization system or chimney by ID Fan.

4. Dilution Fan: This centrifugal fan is used for denitration unit, providing air to dilute ammonia in denitrification system.

1. FD Fan: FD fan supply secondary air, through air preheater, one part air as surrounding air, filling air and so on, which have effect on fuel nozzle flame, and at the same time, cool fuel nozzle. 

The other part air supply oxygen for boiler combustion, and also supply SOFA and COFA, to adjust the boiler combustion. SOFA is separation over fire air, this is the technology to lower nitrogen oxide during the power plant boilers combustion; COFA is compact over fire air.

2. Primary Air Fan: Take medium speed mill, direct-firing pulverizing system as example, the primary air fan provides primary air, one part go through the air preheater, as hot primary air, the other part air do not go through the air preheater, as cold primary air. 

Hot primary air go through the speed mill, drying and bring the pulverized coal into boiler combustor. The hot primary air mix with cold primary air in the entrance of speed mill, adjust the temperature; ventilate the speed mill.

FD Fan: Supply air for boiler combustion; 

Primary Air Fan: Drying and delivery pulverized coal to furnace;

ID Fan (Exhaust Fan): Exhausting out the smoke from boilers. 

In general, 50% capacity allocation, so double large centrifugal fans works together in power plant boilers.

Centrifugal fan has forward curved blade, radial blade, backward curved blade. 

Large Airflow Backward Curved Fans

1. Forward Curved Blade Centrifugal Fan Features
High pressure, low efficiency, easy scaling. 

2. Radial Blade Centrifugal Fan Features
Simple structure, low cost, high pressure, not easy scaling, low efficiency. 

3. Backward Curved Blade Centrifugal Fan Features
High efficiency, and a certain degree of scaling, high technical requirements.
