Forced draft cooling towers are ideal to process larger cooling water flows. The features of cooling towers include reduced power consumption, favorable space requirements, minimized recirculation effects, and optimum operational behavior for salt water application. The hyperbolic shell achieves a natural draft effect which supports the fans arranged around the circumference of the cooling tower shell. Therefore the power consumption of the fans is reduced. The cooling tower is separated in different sections, which can be isolated, to ensure operation with lower water quantities.
Forced Draft Fans are used in power plants. It supplies the air necessary for fuel combustion and must be sized to handle the stoichiometric air, plus the excess air needed for proper burning of the specific fuel for which they are designed. It provides air to make up for air heater leakage and for some sealing air requirements. Forced draft fans supply the total airflow except when an atmospheric-suction primary -air fan is used. It operates in the cleanest environment associated with a boiler and is generally the most efficient fans in the power plant. Centrifugal airfoil or variable-pitch fans are preferred for FD service. If steam coils or other means of heating the air ahead of the FD fans are provided, the consequent air temperature to the fans must be taken into account.
Forced draft vaporizers are designed for customer station, distribution and plant back up applications where high flow rates are required and space is at a premium. It utilizes forced convection as the heat transfer mechanism. Multiple fans mounted at the top of the vaporizer force high velocity air downward through the heat exchange array providing maximum heat transfer and high evaporation rates. The vaporizers comprise a number of individual multi-finned heat transfer extruded elements connected in various series and parallel paths to meet the exact requirements of individual applications.
Forced Lubrication System is used to ensure consistent lubrication at all spindle speeds. Forced lubrication system ensures perfect lubrication of all moving parts and guides. This lubrication system is used to pump the oil around the crankshaft. Forced lubrication system lubricates all running gears and bearing within the headstock.
