Can Biomass Replace Coal? - Renewable Energy World

Jun 25, 2009· Gasifiers need no external energy once they are started. Gasifiers are also very convenient for converting coal power plants because the syngas can be piped to burners inside the coal-fired boiler. The gasifier can be built in any convenient place leaving the coal burning boiler intact for fuel flexibility.

Modelling, comparison and operation experiences of ...

The coal, oxygen and if required a moderator (steam) as well as support fuel (methane) is fed to the burner which can be situated at the top or bottom of the gasifier. A part of the pulverised coal is burnt with oxygen thereby producing the required heat for the endothermic gasification reaction.

Coal & electricity | World Coal Association

Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature (see diagram).

Clean Coal Technologies | Carbon Capture and Storage | CCS ...

In conventional plants coal, often pulverised, is burned with excess air (to give complete combustion), resulting in very dilute carbon dioxide at the rate of 800 to 1200 g/kWh. Gasification converts the coal to burnable gas with the maximum amount of potential energy from the coal being in the gas.
