This article talks about coal fired power plant boiler with the output capacity of 10MW.The 10 MW coal fired power plant boiler is based upon coal fired circulating Fuel Bed (CFB) technology, in which the boiler-based power generation is as the preferred fuel/cycle combination for power generation. More than half of the electricity generated in the world is by using coal as the primary fuel.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
Solid fuel for the Vertical Kiln is similarly prepared in a bowl mill which utilizes heat provided by a gas fired air heater to dry the fuel. This is an "indirect fired" system where the air/fuel mixture is carried to a cyclone and dust collector which discharge into a small pulverized solid fuel storage bin.
Green Pulp Mill: Renewable Alternatives to Fossil Fuels in Lime Kiln Operations. Katja Kuparinen* and Esa Vakkilainen. Pulp mills are making increasing efforts to reduce fossil fuel use and carbon dioxide emissions. Lime kilns, which are typically fired with fuel oil or natural gas, use the most fossil fuel in modern pulp mills.

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
