“…Klafisikasi Fan memiliki rasio spesifik 1,11 dan Blower memiliki rasio spesifik lebih dari 1,11 dan kurang dari 1,20 sedangkan kompresor memiliki rasio spesifik lebih dari 1,20 [3]. Pada kasus konsumsi daya mesin, mesin centrifugal mendominasi di antara total fan dan blower dengan mengkonsumsi 90% energi sektor [4]. Primary air fan dioperasikan secara terus menerus, dalam pengoperasiannya tidak selamanya performa yang dihasilkan fan itu konstan, karena adanya beberapa faktor yang menyebabkan perubahan performa fan sehingga terjadi fluktuasi pada performa fan dan jauh dari peforma desain awal [5].…”

The primary air fan functions as a primary air producer which is used as air to transport coal powder from the pulverizer to the burner to be burned in the boiler furnace. This study aims to obtain the effect of the rotation variation of fan to fluid flow characteristics such as the distribution of total pressure, the dynamic pressure, the pressure static contours, velocity distribution, and the fan optimal efficiency. This study was numerical study with simulated a backward impeller type centrifugal fan in a two-dimension model using Fluid Computational software with the multiple reference frame method with the variation of fan rotation. Based on the visualization of the pressure contour and velocity distribution, it could be concluded that there was a volute phenomenon, this was indicated that the greater the volume area in the volute is the greater the total pressure value too. Based on the visualization of the outlet velocity distribution at the position of -0,8531m to -1,01301m, it was found that the velocity is close to the value of 0 m/s2. It showed that the minimum velocity in the area due to the volute tongue radius occurs a flow collision and it impacted the velocity in the area decreased up to V=0. From the simulation results, it was found that the greater the fan rotation value was the greater the efficiency value too. It would be verified by the actual operating data of the centrifugal fan with a minimum rotation range value of 1194 rpm to a maximum of 1468 rpm

“…The resultant peripheral velocity at the inlet of impeller is obtained using the relation shown in equation (5). Beena Devendra Baloni et.al [5] suggested that the blade inlet angle should not exceed 35.26° for the effective operation of the impeller. They have also mentioned that the selection of the number of blades should also be taken care as too many numbers of blades would restrict the motion of fluid and very few of them would not guide fluid properly.…”

“…Bruno Eck also expressed in a patent (US3306528A) that there is strong relationship between diameter ratio, and number of blades. The resultant peripheral velicity at the inlet can be calculated using equation (5). The inlet blade angle (β 1 ) and impeller width (b) play a vital role in deciding the performance parameters of the centrifugal fan as stated earlier.…”

Beena Devendra Baloni et.al [5] have worked on a unified design procedure in order to achieve improved performance parameters for the same pressure head of industrial blower. The flow rate of the boiler designed through their unified theory was increased by 35% and showed minimum losses.…”

The tightness of electro-technical components for dust entrapment is an extremely important parameter to be considered for effective functioning. International Electro-technical Commission (IEC) developed standards for testing the parts under severe environments like rain, dust etc. The procedure for developing and conducting the dust proof test is known by IEC as 60068-2-68 standard. The blower is an essential component used in the dust test system in order to create a forced airflow along with dust to simulate a dusty environment. The radial tip centrifugal blower is designed in this work for the application of dust test chamber. The pressure and velocity of airflow at the outlet of the radial tip centrifugal blower is mostly influenced by inlet blade angle (β 1 ), impeller diameter (D 2 ) and impeller width (b). The design procedure is elaborated and the above said design parameters are optimized using iterative procedure using MATLAB software. A numerical analysis is carried out using ANSYS Fluent software for the design of Taguchi L9 orthogonal array. In the perspective of further exploring the relationship between design parameters of blower and output parameters like pressure and velocity, a statistical analysis is carried out using Design-Expert software. The optimized design parameters are then used for manufacturing the blower. The experimental test is carried out on the designed blower. The experimental, numerical and statistical results for the optimized design parameters are compared and known to be in good consensus.
