Project description

Vattenfall Heat Poland 2010-2011, 2011- in progress	Siekierki CHP boiler OP230 K-1 conversion to biomass fired BFB boiler. The project includes conversion of the boiler and implementation of biomass handling systems with the systems enabling deliveries of approx.. 320,000 t/a biomass by rail and by road. A feasibility study was prepared to determine the project concept. The study analysed two solutions for boiler operation: common steam header with other boilers or as a separate unit (boiler + turbine set). Concept of flue gas condensing system and biomass handling (320,000 t/a pellets) was described. Economic analysis of the project was made as a basis for optimising project alternatives. The scope of work also included preparation of environmental impact report and an application for environmental permit and preparing an application for land development conditions, including permitting procedures and obtaining the said permits for the project. The work also included preparation of tender documents (tender specification, contract) for two tenders: to select unit modernisation contractor and biomass handling system contractors, as well as participation in the evaluation and selection of contractors.

El. Rybnik S.A.(EDF Polska) 2009	Review of technologies for biomass use in energy prodution and analysis of application at Rybnik Power Plant in order to increase biomass utilisation (Feasibility Study). The objective of the study was to determine best technical solutions enabling the increase of biomass utilisation up to 700 000 Mg/a. Multi-alternative concept analyses were made, taking into account co-firing various biomass types with coal in the existing unit boilers, as well as concepts of constructing a dedicated biomass firing installation (new boilers, biomass gasifier). Analyses covered biomass at different processing level, such as wet biomass, dry biomass, torrefied biomass, liquid biomass, straw in bales. The study analysed issues related to biomass storage and logistics, including the existing transport limitations. Analysis of formal conditions for power to be qualified as renewable was made, as well as the analysis of metering and billing issues.
Dalkia Łódź S.A. 2009	Technical and economic guidelines for converting OP230 boiler to a biomass fired fluidised bed boiler at EC-4 CHP Plant in Łódź (biomass consumption 370,000 t/a.). A detailed concept of boiler conversion was prepared with BFB furnace, technology of biomass combustion was presented together with installation parameters. Influence of modernised unit on the other Dalkia Łódź’s plants was analysed. Biomass transport and logistics assumptions as well as biomass handling system were prepared. Analysis of economic viability of the project was carried out.
EC Białystok S.A. (E.On Group) 2008	Concept of a heat recovery system from flues gas condensation for a 75 MW boiler fired with biomass (fuel humidity approx. 40%). The study presented multiple alternatives for the 13-15 MW system consisting of a scrubber and a condenser recovering head for district heating. Technical solutions were presented as well as location and connection of the heat recovery system with flue gas ducts, DH system and raw water system. Technical and economic analyses were made, as well as project profitability analyses, taking into account environmental issues and grants.

A number of technical and economic alternatives were analysed for a forecast heat demand of approx. 100MWt. Main alternatives included: Waste-To-Energy project based on unsorted municipal wasted and alternatively energy fraction separated from waste and a biomass installation, as well as heat accumulator with capacity of approx. 8000 m3. Biomass types analysed included straw, pellets and wood chips.
ZEW Kogeneracja S.A. (EDF Polska) 2007	Study of biomass generation unit at ZEW Kogeneracja S.A.”, aiming to find an optimum technical and economic alternative for using biomass fuel for renewable energy production at Wrocław and Czechnica CHP Plants.
