Technical description of WtE(waste to energy) facility inDonetsk, Ukraine

Abstract: The main objective of this thesis project is to analyze some selected aspects of the feasibility study done in connection with the planning of a new WtE (waste-to-energy) facility in the city of Donetsk, Ukraine. The report pictures the present situation in Donetsk, existing infrastructure and national regulations, selected location of the facility and suitable waste fuels for incineration, focusing on some important items such as: land allocation and logistics; waste management strategy (collection and sorting, garbage trucks, roads); fuel characteristics and incineration plant operational strategy; existing infrastructure and limitations (city water system, natural gas system, electricity system, district heating system). The study describes the technical solutions chosen for the WtE facility, the civil works and building service systems, the operation and maintenance concept of the facility. The focus lies particularly on the general technical design criteria - operational functions, availability and redundancy; the fuel handling processweighing, quality check, waste bunker, fuel treatment; the waste incinerator and steam boiler technology, slag extracting system, hydraulic piping, auxiliary systems, boiler performance and steam data; the flue gas cleaning system; the steam turbine and electrical generator drivetrain; and auxiliary systems. Major attention is laid upon the operational strategy and functionality of the WtE complex involving the waste incinerator and combined heat and power (CHP) plant, in order to be best adapted to the fuel resource availability, environmental regulations, and the district heating network load profile.
