In order to optimise pulverised fuel flow many aspects need to be taken into account. The major areas of a power plant where improvements can be made are the mills, air/fuel ratio, pipework and boiler. However, before any optimisation can be achieved, measurements which are not only reliable and repeatable, but ideally in real time, must take ...

Pulverized coalfired boiler. A pulverized coalfired 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 ...

In a coalfired power plant, pulverised coal is pneumatically transported from the mills to the burners using air. Typically, the air should have a velocity of approximately 20 m/s, whereas the mass loading of coal should be approximately kg coal/kg air (Storm and Reilly, 1987). These requirements ensure that the pneumatic transport of coal ...

Coalfired plants are the most widely used power plant today. They involve the combustion of coal producing high pressure (typically psig, ~165240 bar) and high temperature (>500ºC) steam which is used to drive a turbine at synchronous speed (3000 rpm in countries such as the UK with a 50 Hz supply frequency, 3600 rpm in ...
