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.

Jun 06, 2011 · The firing rate of a single neuron is a sigmoidal function of the feeding input. This is shown by obtaining the pulse period τ j of a neuron. It is the time required for the threshold to decay from its recharged initial height down to the internal activity level (Figure 2).Consider equation (4) when the threshold is recharged with a single pulse by an amount V t For a constant feeding input F
