The techniques covered include mass reduction of the links, dyad addition, addition of springs and dampers, use of a torsional-vibration isolator and use of a flywheel (which does not reduce peak
Standards and Technical Documents - NOX Reduction On Coal-Fired Units Utilizing Combustion Airflow Measurement And Control - POWID 2007
Description: coal flow measurement to adjust air to fuel ratios. For the Lee 3 project, the DCS was also modified to allow control of mass flow of air to each overfire air port as well as air to fuel ratio control of each burner. This was accomplished by utilizing the burner secondary air disk to control burner

Spend Your Time Engineering, Not on Differential Equations
with something as simple as a spring-mass-damper system, for example, users must draw the free body diagram and then generate the governing equations between the physical components. Next, users must derive the differential equations for the system, convert them to integral form, and, finally, break
