[PDF] Modeling and Parameter Identification of Coal Mill
The coal mill used in the coal-fired power plants is modeled in view of the controller design rather than the educational simulator. The coal mass flow and the outlet temperature are modeled by reinvestigating the mass balance and heat balance models physically. The archived data from a plant database are utilized to identify the model parameters.

Modeling and Control of Coal Mill NTNU
Abstract: The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.
Ellenroad Mill Wikipedia
Ellenroad Mill was a cotton spinning mill in Newhey, Milnrow, Rochdale in England. It was built as a mule spinning mill in 1890 by Stott and Sons and extended in 1899. It was destroyed by fire on 19 January 1916. When it was rebuilt, it was designed and equipped as a ring spinning mill..

Compound steam engine Wikipedia
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional
