Canada Blower draft fans play an important role in thermal power plants because they regulate the air pressure inside boiler system. Draft fans are broadly divided into two types – Forced Draft (FD Fan) and Induced Draft (ID Fan). Apart from the draft fans, there are also other basic types of Canada Blower process fans used in power plants. They are primary air fans and flue gas recirculation fans. Draft Fans

The primary difference between a forced draft and induced draft is, FD fan forces outside air into the heating system whereas ID fan draws flue gases from the system out into the atmosphere. Both FD fan & ID Canada Blower fan operate in such a way that it balances the air system in the boiler to make the combustion process efficient.

Canada Blower Forced Draft Fan

FD fan or forced draft fan, draws air from the atmosphere and forces it into the furnace through a preheater. These fans are located at the inlet of the boiler to push high pressure fresh air into combustion chamber, where it mixes with the fuel to produce positive pressure. The most common centrifugal fans used as FD fans are backward curved and airfoil centrifugal fans.

In power plants, where coal is used as fuel for combustion, FD fans are used as secondary air fans to regulate proper combustion and maximize efficiency of the fuel.

A typical Canada Blower FD fan arrangement uses inlet and outlet dampers to control and maintain the required air pressure inside the system. These fans have a wheel at the center that is hung on the shaft along with inlet boxes, silencer, filter and rain hood.

When compared to ID fans, FD fans are easier to maintain and have cleaner operating conditions.

Canada Blower Induced Draft Fan

Induced draft fan is normally located at the outlet between dust collector and chimney.

The fan takes hot flue gases from the boiler through dust collector and delivers it to the chimney into the open atmosphere. ID fan creates negative pressure or suction to discharge the gases out after combustion from the furnace.

Since ID fans can handle hot flue gases, they have more corrosion and erosion problems even when used with Electrostatic precipitators.

The most common type of fans that can be used as ID fans are radial fans and backward inclined blade centrifugal fans.

Other Canada Blower process fans

PA fans

The main function of the Primary air fan or PA fan is to carry fuel to the furnace for combustion.

In power plants PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area. These fans produce a pressure upstream the pulverizer, to push the coal and air mixture through pulverizer into the furnace.

The most common centrifugal fan used as PA fan is backward curved centrifugal fan.

Flue gas recirculation fans

Gas recirculation fans (FGR) are typically used in power plant boilers to reduce the flue gas pollution content in the gases exhausted from thermal combustion processes.

Flue gas re-circulation is a highly effective technique that significantly reduces the Nitrogen oxide (NOx) emissions from burners. Controlling NOx is critical as it the largest contributor to other types of harmful pollutants. NOx emissions are mostly derived from the nitrogen in the combustion air (thermal NOx). These pollutants are produced during combustion process when nitrogen and oxygen react at elevated temperatures. NOx emission levels can be greatly reduced in industrial boilers by recirculating the flue gases from the boiler exhaust duct into the main combustion chamber.

Most common types of Canada Blower gas re-circulation fans are backward curved centrifugal fans.

Canada Blower Company is a supplier of Industrial and Commercial fans and ventilators for all air moving applications.

Canada Blower SQBA & SQDA Square Centrifugal Inline Fans are recommended for a wide range of general exhaust applications where low, medium and high ranges of air volume and pressure are specified, in both ducted and non-ducted ventilation systems. Fan applications include virtually all types of light manufacturing, commercial and institutional buildings .

Designed for easy positioning and quick installation, the versatile Squre In-Line Fan can be located inside equipmenr rooms, in ceiling spaces or as part of O.E.M. equipment.

The advantages of an Canada Blower SQBA belt-drive fan over a SQDA direct-driven fan include quieter operation, adjustable performance to suit operating needs and availability of larger air volume fans up to 30,000 CFM.

The Canada Blower SQBA fan utilizes a standard V-belt drive design with variable pitch cast iron motor pulley for adjusting fan speed. Heavy duty pillow-block bearings with cast iron housing are sel-aligning and relubricable. Available fan accessories are: vibration isolators, inlet & outlet flanges, backdraft & motorized dampers, variable inlet vanes, round duct connectors, special motors, disconnects.
