the effect of bulk gas diffusivity on apparent pulverized

The effect of bulk gas diffusivity on apparent pulverized

Jan 01, 2019· Apparent char kinetic rates are commonly used to predict pulverized coal char burning rates. These kinetic rates quantify the char burning rate based on the temperature of the particle and the oxygen concentration at the external particle surface, inherently neglecting the impact of variations in the internal diffusion rate and penetration of oxygen.

pulverized coal-fired boiler - wikipedia

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

experimental study of diffusion combustion of a fine

EXPERIMENTAL STUDY OF DIFFUSION COMBUSTION OF A FINE

This paper presents an experimental study of diffusion jet combustion of gas at different flow rates of CH4–N2 and a constant flow rate of coal. Blow-off curves for a diffusion flame for different nozzle diameters are obtained. It is shown that an increase in the the nozzle diameter causes a decrease in the minimum residual flow rate of the fuel gas at which stable combustion is possible.
