The energy outputs from this kind of waste
incinerators are:
– electricity – can be easily calculated; the incineration
process itself may use some of the
produced electricity.
– steam/hot water – the heat released in the
combustion process can be recovered to feed
industrial or domestic users.
To electrical energy recover from the steam produced
by the boiler is mandatory to provide a steam
turbine – generator group. In situations where economic
incentives are provided to support the
production of electrical energy from incineration
(e.g. as a renewable source) there may be a price
differential between purchased and exported electricity.
Plants may then choose (for economic reasons) to
export all of the electricity generated by the
incinerator, and import from the grid, that which is
required to run the incineration process itself. Where
this is the case, the incineration plant will often have
distinct electricity flows for input and output. [1, 3]
Combined heat and power (CHP) plants provide
both heat and electricity. Steam/hot water not used
by the incineration plant can be exported.
Considering this facts and the Timişoara potential
background, a suitable solution for thermal treatment
of MSW is the implementation of a grate incinerator
with an energetic group that used a condensation
steam turbine.
