Abstract (Croatian)

U radu su opisane komercijalno dostupne kogeneracijske tehnologije koje koriste krutu biomasu kao gorivo, a čija snaga ne prelazi 1 MWe. Opisane kogeneracije su: ORC kogeneracija s termouljem kao prijenosnikom topline, ORC kogeneracija s direktnim isparavanjem organskog medija te plinski motor pogonjen generatorskim plinom dobivenim rasplinjavanjem biomase. Posebno su proračunate i opisane komponente ORC kogeneracije s direktnim isparivanjem organskog medija čija je električna neto snaga 700 kW. Proračunata kogeneracija se planira postaviti unutar drvnoprerađivačke industrije, a proizvedena toplinska energija će se koristiti za sušenje sirovine iz koje će se proizvoditi peleti, te za grijanje radnih prostora. Kako bi se mogla predvidjeti potrošnja toplinske energije iz kogeneracije, izračunate su potrebe za toplinskom energijom, pri čemu su uzete u obzir klimatske prilike na mjestu planirane kogeneracije. Na kraju su navedeni glavni financijski pokazatelji pogona potrebni za izračun profitabilnosti projekta.

Abstract

This paper describes the commercially available cogeneration technologies that use biomass as fuel and whose electrical power does not exceed 1 MW. Described cogeneration are: ORC cogeneration with oil loop, ORC cogeneration with direct evaporation and a gas engine powered by generator gas, obtained from biomass gasification. Components of 700 kW ORC cogeneration with direct evaporation that has net electrical power of 700 kW, were calculated and described . Calculated cogeneration is planed to set up within wood industry, which will use heat for heating working premises and for drying material that will be used for production of pellets. In order to predict consumtion of heat from cogeneration, heat requirements are calculated, and in this calculations are climatic conditions of the location (where cogeneraton is planed to be) taken into account . Finally, main financial indicators of operation which are necessary for calculation profitability of the project are shown.
