In this report, both technically and using a finite element analysis approach, the influence of design parameters on the fan noise frequency of the centrifugal blower impeller are studied. Studies of finite element analysis was conducted to test the theoretical conclusions and also to explore the influence of various configuration alternatives on the fan's noise frequency. The study of the Finite elements implies that the empirical and theoretical results are in strong agreement. The experimental research of numerous fan configurations provides details on the possibilities for noise reduction. Any vibration will still be produced by the operation of some mechanical device. Our goal is to mitigate the influence of these vibrations, since vibration is inevitable although undesirable. From nuisance interruption to a disastrous collapse, the outcome of excess vibration may differ. Any vibration must be produced by all fans. They constantly rotate and, because nothing is ideal, it is important to produce cyclic powers. It is only when a certain amplitude of vibration crosses that we call it evil. Vibration may be merely an indication of any process problem, or it may be a source of other issues. Finally, vibration may propagate into neighboring areas and interact with processes of precision, or cause irritation for individuals. The goal of this thesis is therefore to present centrifugal blower vibration analysis for materials like steel , aluminum and composite (glass / epoxy).

I- INTRODUCTION Fans and blowers provide air needed for ventilation and industrial processes [1]. Fans produce a pressure in a fan system to transfer air (or gases) against a resistance created by ducts, dampers or other parts [2], [3], [4]. The ventilator rotor collects and transmits energy from a spinning shaft to the air [5], [6], [7]. One of the essential components used daily in Boiler service is blowers. Highly effective fans will make Boiler more powerful. Using Forced Draught (FD) fans, they are used to supply air for fuel combustion in boiler furnace, mounted on the front side of the furnace supplying air either at normal temperature or at elevated temperature, whether air is supplied using air-pre heater [8], [9], [10]. The fans must have a high enough pressure strength to withstand the complete resistance of inlet silencers, air preheating cables, air ducts, air heaters, wind boxes, flame registers, and all other resistance between the fan and furnace air intake [11], [12], [13]. Using Induced Draught (ID) fans, the flue gases produced following fuel combustion can be drawn out. They keep the furnace pressure well below atmospheric pressure. Main Air (PA) fans are used for the atomization of pulverized fuel to provide combustion air. Secondary Air (SA) fans are used to transfer pulverized fuel by way of duct conveying system. FD,
