Energetická analýza procesů v tavenině
Němec, Lubomír ; Jebavá, Marcela
The glass producers face frequently problems of glass quality, energy consumption, investements into technology and environmental damages.
Chování bublin v tavenině v rotujícím válci
Tonarová, V. ; Němec, Lubomír ; Jebavá, Marcela
The goal of this work is to present results of the matematical modeling of bubble behaviour in the centrifugal field.
Vliv proudění skloviny v horizontálním kanálu
Cincibusová, P. ; Němec, Lubomír ; Jebavá, Marcela
This paper deals with removal of single bubbles in horizontal channels with different character of glass flow.
Czech glass - a country museum or a good brand?
Němec, Lubomír
The contemporary production and ownership structure of the czech glass and ceramic industry. The proposed main activities of the czech research to the development of glass and ceramic production in the country.
Bubble behavior in rotating cylinder with glass melt
Tonarová, V. ; Němec, Lubomír
Bubble removing during glass melting may be a slow process if only the gravitatiuonal force determines its rate. This wwork brings derivation of relations governing the one and multicomponent bubble behavior in a rotating cylindr.
Bubble distribution in Channels with glass melt
Cincibusová, P. ; Němec, Lubomír
Equations were derived describing bubble distribution in horizontal and vertical channels with glass melt.
The analysis of the melting process
Němec, Lubomír ; Jebavá, Marcela
The analysis of the melting process provides some non-traditional opportunities when intersifying the main homogenization processes.
Redox equilibria of sulphur in glassmelts
Kloužek, Jaroslav ; Němec, Lubomír ; Arkosiová, Miroslava
The combination of experimental and computational methods used for the study of redox equilibria of sulphur in glassmelts makes possible to reveal mechanism and time sequence of redox phenomena taking place during melting process. Both methods were applied for the optimization of sc. reducing sulphate refining realized by the addition of sulphate and reducing agent to the glass batch. The results of experiments supported by the model calculation showed that proper combination of both components at the same time improves homogenization and refining of glass melt and suppresses unwanted bubble nucleation at maximal melting temperatures.
Bublinové modely, získávání informací a použitelnost modelu
Jebavá, Marcela ; Kloužek, Jaroslav ; Němec, Lubomír
Two experimental and theoretical methods are presented to acquire equilibrium and kinetic data of gas dissolving and transport in glass melts.The mentioned values are crucial for bubble modelling during glass melting and consequently for the quality of industrial glasses.
Účinek bublin na redukční stav skla
Štáhlavský, O. ; Brada, J. ; Trochta, M. ; Němec, Lubomír
The time-temperature history of glass melt may influence its redox state and consequently, the refining ability, glass reboiling or melting of recycled glass.
