Abstract
U radu je opisan princip rada kogeneracijskih postrojenja te neke dostupne tehnologije koje koriste krutu biomasu kao gorivo. Naglasak je stavljen na vodeno-parno postrojenje te na postrojenje koje koristi organsku radnu tvar, tzv. ORC postrojenje. Također, izrađeni su pojednostavljeni matematički modeli dinamike procesa za termouljni i vodeno-parni kotao s izgaranjem biomase na rešetki kako bi bilo moguće simulirati utjecaj vlažnosti biomase na parametre na izlazu iz kotla. Proveden je termodinamički proračun izgaranja te dimenzioniranje veličina u sustavu. Početni podatak bio je potreban toplinski tok koji se mora prenijeti na radni medij koji iznosi 5MW. Nakon toga uslijedila je simulacija utjecaja promjenjive vlažnosti na temperature na izlazu iz izmjenjivača te su tablično prikazani dobiveni podaci. Na kraju su opisani problemi koje prevelika ili premala količina vlage u biomasi može izazvati u postrojenjima te regulacijske mjere koje mogu taj učinak kompenzirati.
Abstract (english)
This work describes the general principles of some commercially available cogeneration technologies that use solid biomass as a fuel. Emphasis is placed upon water-steam and ORC cogeneration plants. Also, simplified mathematical models of sintetic oil and water-steam boilers with combustion of solid biomass on a grid were made in order to simulate the impact of biomass moisture on working fluid exit temperatures. The thermodynamic calculation of boiler was made and plant dimensions were chosen. Initial data was the required heat flow that needs to be transferred between flue gases and working fluid with a value of 5MW. After that the simulation of variable moisture impact on working fluid exit temperatures was made and the results are shown in pictures. At the end, some problems that occur from variable moisture in plants were described and some regulatory measures proposed.
