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.

In the Pulverized Coal Boiler, the coal pipes layout varies and each coal pipe has a different length and layout to the burner. It can rapidly and accurately measures the coal flow up to 8 pipes per mill (there is no limitation for the number of mills). It is drift free and independent from pressure and temperature operation in a wide range.

pulverized coal flow measurement restaurantlegargantua.fr
In a pulverized coal-fired boiler of a large power plant, an oxygen analyzer is essential for combustion control. Exhaust gases from the pulverized coal boiler contain a large quantity of dust and flow very fast. Oxygen analyzers that employ a sampling method may be subject to wear or clogging, resulting in increased maintenance workload and cost.

Pulverized coal-fired boiler Wikipedia
The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
