Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle . The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam .
BIOMASS GASIFIERS. Gasification is a process that can find new value in traditional fuels such as coal, wood, and oil. More impressively, gasification can unlock the energy value of waste materials such as waste wood from construction, forest, lumber, and paper industries, as well as household waste from towns and cities.
Lignite and Wood Gasification Boilers C18S lignite gasification boiler. The boilers are constructed for burning wood and coal (lignite) on the principle of generator gasifying with the use of a gas exhaust ventilator, which withdraws the combustion gases from the boiler. The boiler body is produced as a weldment of 3 - 8 mm steel sheets.

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. There are a few minor losses in boiler which can also
M.S. Blinderman, A. Taskaev, in Underground Coal Gasification and Combustion, 2018. 12.1 Introduction.
