Using Biomass for Cogeneration of Heat and Electricity
Vašíček, Martin ; Macháček, Jan (referee) ; Toman, Petr (advisor)
Theoretical part is concerned to disposal of biomass kinds and various forms of applications. The basic characteristic for each kind of biomass and their forms are presented. Characteristics of energy plants and woods are more detailed. In work are described two fundamental kinds of combustion, fluid combustion and grate combustion, which are used in power plants and heating plants. The work describes process of gasification and obtaining wood gas from biomass. Evaluation of (energy plants, wood biomass and the rest from agriculture production – straw) in light of heating power, treatment, handling, ash creation and environment pollution is provided. Work is concerned to redemption price history, volume of produced biomass and perspective to future. Czech Republic legislation gives support to biomass usage by guarantee for electric energy purchasing and same redemption price perspective. Explain term of cogeneration, possibility of cegeneration units application – their kinds with fuel usage aspect (biogas, natural gas, wood gas). Practical part is concerned to design of such kind of unit. Cogeneration unit will be installed in company, which producing wood. For this reason will be used wood biomass to produce wood gas. Size of unit, fuel consumption, and cost saving in comparison to electric energy together with recovery of investment are calculated. In work is drawn out possibility to connect this unit to distribution electrical network, possibility of electric energy distribution and due this to improve backflow. Noticeable are possibilities to get state grant from various grant sources.
