A Thermogravimetric Study of the Behaviour of Biomass Blends During Combustion
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
The ignition and combustion behavior of biomass and biomass blends under typical heating conditions were investigated. Thermogravimetric analyses were performed on stalk and woody biomass, alone and blended with various ...
Lab-scale Technology for Biogas Production from Lignocellulose Wastes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Currently-operating biogas plants are based on the treatment of lignocellulose biomass, which is included in materials such as agriculture and forestry wastes, municipal solid wastes, waste paper, wood and herbaceous energy ...
Resistance Spot Welding of dissimilar Steels
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper presents an analysis of the properties of resistance spot welds between low carbon steel and austenitic CrNi stainless steel. The thickness of the welded dissimilar materials was 2 mm. A DeltaSpot welding gun ...
Plasma Surface Treatment of Powder Materials — Process and Application
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Polyolefin particles are hydrophobic, and this prevents their use for various applications. Plasma treatment is an environment-friendly polyolefin hydrophilisation method. We developed an industrial-scale plant for plasma ...
Heat Exchangers for Condensation and Evaporation Applications Operating in a Low Pressure Atmosphere
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper presents a state-of-the-art study of a heat transfer process in liquid spraying heat exchangers placed in a vacuum chamber. The experimental case studied here describes the behavior of a falling film evaporation ...
Change of Pressing Chamber Conicalness at Briquetting Process in Briquetting Machine Pressing Chamber
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
In this paper, we will present the impact of the conical shape of a pressing chamber, an important structural parameter. Besides the known impact of the technological parameters of pressing chambers, it is also very important ...
Energy Recovery from Contaminated Biomass
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This study focuses on thermal gasification methods of contaminated biomass in an atmospheric fluidized bed, especially biomass contaminated by undesirable substances in its primary use. For the experiments, chipboard waste ...
Modularity of Pressing Tools for Screw Press Producing Solid Biofuels
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper focuses on the development of the newly-patented structure of a screw briquetting machine for compacting biomass into a solid biofuel. The design of the machine is based on the results of a comprehensive study ...
Biomass Gasification — Primary Methods for Eliminating Tar
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This present paper deals with primary methods for reducing tar in biomass gasification, namely by feeding a natural catalyst into a fluidized bed. This method is verified using an experimental pilot plant.
Hierarchical Modeling of Mastic Asphalt in Layered Road Structures Based on the Mori-Tanaka Method
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
We present an application of the Mori-Tanaka micromechanical model for a description of the highly nonlinear behavior of asphalt mixtures. This method is expected to replace an expensive finite element-based fully-coupled ...
