Such problems are often encountered in engineering designs: drawing moving targets orbits, however either there is no analytical formula of the orbit equation, or the derivation of getting a track equation is cumbersome; designing size of an equipment requires solving a complex transcendental equation. In order to address these matters, here were cited three instances, plotting the trajectory o...

In this work, the development of a point-of-care (PoC) system to capture aerosol from litres of air directly onto a microfluidic lab-on-chip for subsequent analysis is addressed. The system involves an electrostatic precipitator that uses corona charging and electrophoretic transport to capture aerosol droplets onto a microfluidic air-to-liquid interface for downstream analysis. A theoretical s...

This paper presents a numerical flow model applied to a 3D geometry of an electrostatic precipitator (ESP). The flow simulation is performed by using the computational fluid dynamics (CFD) code FLUENT. Realizable k-ε model for turbulence condition inside the ESP is applied. In the simulation, the perforated plates are modeled as thin porous media of finite thickness with directional permeabilit...

Wood is often combusted in small scale units for domestic heating. Although the total particle emission levels in Germany have declined steadily over the years, small scale wood combustion is an increasing source of indoor and outdoor air pollution. A novel space charge electrostatic precipitator (ESP) was developed for control of fine particle emissions control from wood combustion stoves and ...

As one of the effective control devices of air pollutants, the wet electrostatic precipitator (ESP) is an effective technique to eliminate acid mist and fine particles that are re-entrained in a collection electrode. However, its collection efficiency can deteriorate, as its operation is subject to water-induced corrosion of the collection electrode. To overcome this drawback, we modified the w...

Hierarchically structured aluminium oxide was hydrothermally synthesized with carbamide as a precipitator. Raman spectroscopy, SEM spectroscopy, and X-ray phase analysis were used to investigate morphology and parameters of porously structured aluminium oxide as influenced upon by concentration of reactive solution, excessive portions of precipitator, and the counterion type. Differing mechanis...

It has been approximately ten (10) years since the first electrostatic precipitator was applied to an incinerator in the United States by the City of New York. Since that time, numerous installations have been made on various types of incinerators. This paper gives a brief description of the majority of the installations as well as actual performance data as compared to manufacturers' guarantee...

Environmental degradation and Economic growth are two important proofs in sustainable development which are followed by steel industry. In this case, energy and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally suitable dust collector for electric furnace. In this article, the consumption ...
