Electrostatic Precipitator Penetration Function for Pulverized Coal Combustion

Electrostatic Precipitator Performance in Indian Pulverized Coal Based Thermal Power Stations - Problems and Solutions

Coal used in Indian thermal power stations is of inferior grade having low heat value and high ash content due to drift origin. However, Indian power coal ash is specially known by its refractory in nature and low sulphur (below 0.5%) and alkalis (less than 1.5%) contents. Due to presence of low sulphur and alkalis and consequently having very high ash resistivity (10 – 10 O cm) it is difficult...

Interactive System for Pulverized Coal Combustion Visualization with Fluid Simulator

Designing pulverized coal combustion simulation and visualization systems is still a complex task. The current solutions, such as the commercial CFD packages are focused on the precision of the computation. Our solution is suited to the education and computer graphics area, where the precision does not take the first, but also not the last place. The main factor in our solution utilizes the int...

Measurement and capture of fine and ultrafine particles from a pilot-scale pulverized coal combustor with an electrostatic precipitator.

Experiments were carried out in a pilot-scale pulverized coal combustor at the Energy and Environmental Research Center (EERC) burning a Powder River Basin (PRB) subbituminous coal. A scanning mobility particle sizer (SMPS) and an electrical low-pressure impactor (ELPI) were used to measure the particle size distributions (PSDs) in the range of 17 nm to 10 microm at the inlet and outlet of the ...

Characterization of Nano-Ashes Generated during Pulverized Coal Combustion

Model of pulverized coal combustion in a furnace

We describe behavior of the air-coal mixture using the Navier–Stokes equations for gas and particle phases, accompanied by a turbulence model. The undergoing chemical reactions are described by the Arrhenian kinetics (reaction rate proportional to exp ` − E RT ́ , where T is temperature). We also consider the heat transfer via conduction and radiation. Moreover we use improved turbulence-chemist...
