Sažetak

In the paper the techno-economical analysis of the waste-to-energy plant
that includes combined heat and power production is presented. The
technology of waste combustion on the grate is chosen as the proven
technology most often in use even today. Selection of this technology
assumes application of all the most stringent environmental protection
standards. The paper analyses two variants of flue gas cleaning systems.
Due to high requirements on environmental protection, the operating
and maintenance costs of the facility are rather high while the calorific
value of the municipal waste burned is relatively low (around 10 MJ/kg),
which brings the waste-to-energy plant under consideration to the brink
of economical viability for the given annual capacity of 100.000 tons of
waste and the limiting gate fee value of 105 EUR per tone of waste, if
solely direct cost-effectiveness is considered.
The parameters on which the cost-effectiveness of the waste-to-energy
cogeneration plant depends range from purely technical, like plant
capacity and the waste calorific value (including percentage of moisture
and biodegradable matter) to entirely economical, such as loan conditions,
costs of flue gas cleaning, costs of hazardous waste disposal, revenue from
selling of electricity and heat, and the most important factor – charge levied upon a waste received at a waste-to-energy plant (the gate fee). High costs of ash and residue disposal could influence the total economic viability of the plant.
