The result is poor heat-rate and undesirableemissions. Upgrading your actuators improves these and canresult in immediate fuel savings.Emissions ReductionAvoid expensive fines, upgrading or replacing old OFA, SOFA orfuel/air damper actuators helps reduce emissions and the finesassociated with not meeting EPA directives.Reduce maintenance costsOld damper actuators result in increased repair and maintenanceexpenses. Upgrading them reduces maintenance and theassociated costs in terms of spares, time and unplannedshutdowns.Reduce operating costsUpgrading damper actuators saves fuel costs by reducingprocess variability. ABB’s pneumatic positioners also have lowair consumption reducing compressor operating costs. Giventhe number of final control elements in the average plant, thetotal cost savings can reach 100,000’s per year.ABB Instrumentation Upgrade solutions for damper actuators 3
Damper drives over 10 years old are costing you moneyDid you know? ABB purchased Bailey in1999 and fully supports allof their products includingthe thousands ofBailey damperdrives installed overthe years.

They excelin applications where exact control and speed cansave fuel costs or improve efficiency e.g. forceddraft and induced draft dampers. They utilize thepower of digital technology to provide exact controland built-in diagnostics.Did you know? ABB’s Contrac drives are maintenancefree for 10 years!RHD500 Contrac Electric Actuator6 Upgrade solutions for damper actuators ABB InstrumentationUP5/6 Pneumatic Actuator Electric Rotary Actuators: ABB Contrac Actuators are thepremier choice for the power industry and other industrialenvironments where high performance and superior reliabilityare demanded. With a wide range of output torque theyare available in sizes to meet all requirements. Offering highaccuracy, ease of use and minimal scheduled maintenance,these damper drives are the ultimate upgrade to your oldinstallations. Pneumatic Rotary Actuators: ABB UP’s are built on theBailey heritage and designed as a direct replacement for theold series of Bailey damper drives. The ABB UP1 throughUP6 are available with torque ratings of 90 to 4700 ft.lbsmaking them suitable for most damper applications. Pneumatic Linear Actuators: The ABB LP series of actuatorsprovide a cost-effective linear actuation solution that is ideallysuited for applications like windbox dampers and louvers.The LP is a direct drop-in replacement for many “older” pistonactuators.

This project makes use of a mass-spring-damper model. A mass-spring-damper system describes a mass that is connected to both a spring and a viscous damper. The total amount of force applied to the mass is thus the sum of the force applied by the spring and the force applied by the damper. The spring force can be calculated as !! !"

In the English writing system, many of the graphemes (letters and letter groups) have more than one possible pronunciation. Sometimes, specific sequences of letters can alert the reader to the possible pronunciation required; for example, note the letter sequences shown as ‘hollow letters’ in this guide as in ‘watch’, ‘salt’ and ‘city’ - indicating that, in these words with .
