The objective of this study is the comparison of various sticking probabilities based on three different approaches: (1) empirical viscosity models, (2) experimental results based on ash fusion and thermo-gravimetry and (3) thermodynamic equilibrium calculations. More specifically the viscosity...

Recent built low energy school buildings have adopted a novel heat recovery heat pump and classroom ventilation system. School building energy conservation performance and classroom air quality enhancement will be simultaneously investigated in the present work. Heat recovery efficiency of the...

Pyrolysis and gasification behavior is analyzed at operation conditions relevant to industrial scale entrained flow gasifiers. A wire mesh reactor and the Pressurized High Temperature Entrained Flow Reactor (PiTER) are used to measure volatile yield of Rhenish lignite, a bituminous coal and...

The growing share of renewable energy generation eventually could lead to increased fluctuations in power supply and to negative residual loads. Therefore flexible power plants as well as significant long-term energy storage capacity are required. In this paper, an Integrated Gasification...

Environmental damage due to the emission of greenhouse gases from conventional coal-based power plants is a growing concern. Various carbon capture strategies to minimize CO2 emissions are currently being investigated. Unfortunately, the efficiency drop due to de-carbonization is still...

Organic Rankine Cycles (ORCs) are particularly suitable for recovering energy from low-grade heat sources. This paper describes the behavior of a small-scale ORC used to recover energy from a variable flow rate and temperature waste heat source. A traditional static model is unable to predict...
