20.500.12556/DKUM-14564 VODENJE TEMPERATURE POVRATNEGA VODA UPLINJEVALNEGA KOTLA NA LESNA POLENA CONTROL OF WOOD GASIFICATION BOILER RETURN TEMPERATURE Diplomsko delo zajema analizo, modeliranje in načrtovanje vodenja temperature povratnega voda uplinjevalnega kotla na lesna polena. Za doseganje maksimalnega toplotnega izkoristka in popolnega zgorevanja lesne biomase mora uplinjevalni kotel delovati v svojem optimalnem delovnem področju. To pomeni konstantno proizvodnjo toplotne energije ne glede na potrebe sistema ogrevanja. Zato je v sistem ogrevanja vgrajen hranilnik toplote, ki akumulira višek proizvedene toplotne energije, ki jo lahko sistem ogrevanja porablja, ko kotel toplotne energije ne proizvaja. V diplomskem delu je opisan način povezave med uplinjevalnim kotlom na lesna polena in hranilnikom toplote. Temperatura povratnega voda kotla mora presegati kritično vrednost, ki še ne povzroča kondenzacije dimnih plinov. Zato je v povezavo med kotlom in hranilnikom toplote vgrajen sistem za mešanje hladnega medija iz hranilnika in vročega medija iz kotla, za katerega je bilo izvedeno načrtovanje in izvedba sistema vodenja. The diploma work is describing analysis, modeling and control system synthesis of wood gasification boiler return temperature. The gasification boiler must operate at the optimum regime to achieve maximum efficiency and complete combustion of wood biomass, which means a constant heat production regardless of the heating system needs. Therefore, the heat accumulator is installed in the heating system, to accumulate the heat energy excess. When the boiler is out of operation, the heating system could use accumulated heat energy. In this diploma work the connection design between boiler and heat accumulator is described. If the boiler return temperature is below the critical value, the flue gas condensation occurs. The mixing system of cold heating medium from accumulator output and hot heating medium from boiler output is build to rise the boiler return temperature. The core of diploma work represents the design of the control system for mixing valve to achieve the desired boiler return temperature. regulacije sistemi ogrevanja na lesno biomaso uplinjevalni kotel na lesna polena temperatura povratnega voda mešalni ventil enofazni sinhronski motor control biomass heating systems wood gasification boiler boiler return temperature mixing valve single phase synchronous motor true true false [A.
