On the way to reducing emissions released into atmosphere, there is an obstacle in form of solid pollutants produced by households, namely burning fuels small heat sources. In this article, authors deal with development a low-cost electrostatic precipitator, which would be able significantly reduce production particulate matter. This tubular precipitator concept, enhanced dividing precipitation...

An efficient finite volume approach has been used to develop a three dimensional Helmholtz acoustic solver for complex geometries. This acoustic solver was utilized to obtain characteristic mode shapes and frequencies of a baffled combustion chamber. An experimental setup, including stationary and moving sensors, has also been used to measure these quantities for the same model combustion chamb...

The acoustic wave velocity depends on elasticity and density at most materials, but because of anisotropy and especially piezoelectric coupling effect, the acoustic wave propagation at piezoelectric based crystalloacoustic materials, is an applied and challenging problem. In this paper, using modified Christoffel's equation based on group velocity concept, the effect of anisotropy and piezoelec...

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are found on fly ash and in flue gas of municipal waste incinerators. Municipal waste incinerators seem to be the most important source for PCDDs and PCDFs emitted into the air during the last decades. PCDD/F formation takes place in the cooler zones (250 °C-450 °C) of a municipal waste incinerator, at the elect...

The paper presents a theoretical analysis on the dynamic characteristics of the current-voltage characteristics of plate-type electrostatic precipitators (with three fields) from an electric power station. Measures were made with signal conditioning, data acquisition card, and PC. It was found that these characteristics can not be mathematically model, due to their permanent modification (have ...

the electrohydrodynamic (EHD) flow in a relatively wide electrostatic precipitator (ESP) (width:height = 2) is 2-or 3-dimensional (3D). The previous our measurements of 3D time-averaged flow velocity fields suggested that the flow in the ESP duct centre is almost 2-dimensional. In this paper we present both the 3D instantaneous and time-averaged flow velocity fields in a relatively wide ESP (wi...
