Mill Steam Inerting System Review and Performance Validation

During a ball tube mill start-up, Riley Power Inc. recommends a specified steam flow rate to be introduced and mixed with the primary air entering the mill to establish an inert atmosphere in the mill. During mill shut down, the same inerting process starts when the coal feeder is stopped or mill coal inventory reaches a certain level.

Coriolis scales - Coriolis flow rate scales - Mass flow rate

Coriolis scales, also known as Coriolis flow rate scales or mass flow rate measuring devices, measure the weight of a mass flow using the Coriolis force. They are most commonly used to measure bulk materials such as dusts, powder or gravel. Coriolis scales are also good for measuring granulates or cereals.

Gravimetric and Volumetric Coal Feed Systems for Boilers

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.

Dirtiest Fossil Fuel the Future's 'Cleanest'?

Hence the long-term goal of clean-coal research of zero-CO2 emissions. For instance, many researchers hope to turn coal into clean natural gas. The concept isn't new. Cities in the 1800s used massive, dirty ovens to turn coal into town gas to fuel streetlights and gas lamps in homes. During WWII, Nazi Germany turned coal into liquid fuel for tanks.
