Energy from Waste: Difference between revisions

Line 36:

The energy produced by an [[EfW]] facility can either be converted to electricity to boost the National Grid and/or provide heat in the form of hot water or steam for use by nearby developments. A plant facilitating the generation of electrical power and recovery of usable heat from a combustion process is termed a [[Combined Heat and Power]] ([[CHP]]) plant and it is more efficient than [[EfW]] that is focused on power generation alone. [[Energy from Waste]] facilities can be used to generate [[Baseload Technologies | base load power]] as they produce a steady, reliable amount of energy but generally cannot be adjusted to meet peak demands. The development of an [[EfW]] plant is complex, with many inter-locking requirements for successful delivery<ref> WRAP, 2012.

In the most widely used [[EfW]] process, [[waste]] is [[treatment|treated]] via [[Combustion]] on a moving [[Grate]]. Air is introduced above and beneath the [[Grate]] in carefully controlled amounts to ensure proper [[Combustion]]. Good combustion is needed to manage the emissions from an [[EfW]] facility. The hot gases are ~~then~~ released are directed to a boiler to recover the heat. The combustion gases are then cleaned in several stages to strict standards set by the [[Industrial Emissions Directive]], which are monitored by the [[Environment Agency]] ([[EA]]) in England.
