Pulverizer Performance and NOx Emissions

What is known is that Nitrogen in coal is responsible for ~80% of the total NOx formed during coal combustion. American coals are typically between ~0.25% to 1.5% nitrogen. If complete conversion of all fuel Nitrogen took place, this would result in NOx emissions of 0.4 to 2.6 Lbs./MMbtu.

TPS Coal Mills and Fan Performance - SlideShare

Pulverisers • Coal pulverizers are essentially volumetric devices, because the density of coal is fairly constant, are rated in mass units of tons/hr. • A pulverizer accepts a volume of material to be pulverized which is dependent on the physical dimensions of the mill and the ability of coal to pass through the coal pulverizing system.

Pulverised Coal - an overview | ScienceDirect Topics

A coal-fired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9.After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
