Estimating Electric Motor Operating Cost Per Year

Image
Estimating Electric Motor Operating Cost Per Year When determining the operating cost of a project, it is important to remember motor operating costs. To determine these costs by using the following formula: EMOC/YR = (HP) (%FL) (0.746 HP KW) ($/KWH) (HRS/YR)/MOTOR EFFICIENCY Where ·                      Estimated Motor Operating Cost per Year = EMOC/YR ·                      Motor Horsepower = HP ·                      Motor Percentage of Full Load = %FL ·                      Horsepower to KW factor = 0.746 ·           ...

Why you don't need explosion protection on drum filters

Why you don't need explosion protection on drum filters We at  ATMOS360   are in the business of engineering and manufacturing dust collection systems and equipment. As we develop the scope for new systems, as well as upgrades to existing systems, we must evaluate the options for the use of a baghouse filter versus a drum filter. The Need for Explosion Protection One important factor is the need for explosion protection. The cost of an explosion protection system can add as much as $100,000 to the cost of filtration equipment. The need to provide explosion protection on a baghouse filter is typically straightforward and, in most cases, is needed. Drum filters, however, are a different animal and for some installations, explosion protection is not required. Typically drum filters have rounded floors and inlet ductwork designed to provide a low sweeping inlet. This keeps the floor clean and minimizes the amount of material within the dirty air plenum.
