This paper outlines a unique case of the development of strategies to reduce ventilation and heating costs in Konsuln iron ore mine in northern Sweden. The mine, located just south of Luossavaara-Kiirunavaara Aktiebolag’s Kiruna iron ore mine, was

The ventilation power and the temperature increase experienced by steam turbine last stages operating at low load are strongly influenced by some design parameters such as radial clearances, degree of reaction and pitch to chord ratio. This paper pre

The continuous increase of variable renewable energy and fuel cost requires steam turbine power plants to operate with high flexibility. This situation leads to steam turbines running at very low volume flow (LVF) for an extended time. Ventilation po

During very low load operations the last stage moving blades of a low-pressure steam turbine run in ventilation condition. The flow temperature increases mainly in correspondence of the tip region and some heat flows through the inner casing. Flow an
