Abstract:

The article deals with the issue of air pollution by particulate matter. At present, there is a high production of these substances in the sector of heating with small heat sources, compared to the automotive or energy industry. The purpose of this article was to create an experimental numerical model of an electrostatic precipitator and to calculate its efficiency of particle capture in a simulated community.

Authors:

František Šucha, Viera Peťková

Abstract:

One of the basic goals of Eustream is environmental protection Methane emissions are classified according to their origin in three different types: Fugitive emissions, Vented emissions, Incomplete combustion emissions. Searching for leaks during transmission and gas distribution is an important diagnostic activity. Based on the results diagnostic (detection and quantification) the company Eustream prioritizes maintenance activities to eliminate the identified defects. This approach both increases the safety of the operational facilities and decreases losses due to by leaks.

Title:

Refractory Materials for a Reheating Furnaces and their Development in Present Time

Authors:

Miroslav Tatič, Ján Kizek, Ladislav Lukáč

Abstract:

Refractories are inorganic, nonmetalic, porous and heterogeneous materials composed of thermally stable mineral aggregates, a binder phase and additives. They are materials which are resistant to heat and exposure to different degrees of mechanical stress and strain, corrosion/erosion from solids, liquids and gases, gas diffusion, and mechanical abrasion at various temperatures. The contribution deals with composition of lining and with description destructive effect on refractories by which they are brick reheating furnaces in hot rolling mills such as pusher, walking beam and rotary hearth furnaces. In the contribution are summarized practical development experience applied to these aggregates.
