Modeliranje aerodinamskih izgub v pretočnih kanalih čistilnih naprav termoelektrarn

Kellner, Žan (author), Hočevar, Marko (mentor)

Naloga obravnava čistilne naprave z mokro kalcitnim postopkom na termoelektrarnah. Na podlagi enačb za preračun aerodinamskih izgub v dimovodnih kanalih, je bil ustvarjen program, ki omogoča preračun tlačnih padcev za poljubno izbrane elemente sistema. Program omogoča tudi določitev potrebne tlačne razlike, ki jo mora nadomestiti ventilator vleka ob vgradnji čistilne naprave. Delovanje programa je predstavljeno na primeru meritev na čistilni napravi, ki so primerjane s preračuni. Na koncu je predstavljeno tudi delovanje programa na primeru načrtovanja nove čistilne naprave.

• Title: Modeling of aerodynamic losses in the flow channels of thermal power plant treatment plants

Abstract

Thesis focuses on flue gas desulphurisation systems for thermal power plants. Program was created, based on well-known relations for calculation of aerodynamic losses for elements of flue gas duct systems. Program can calculate pressure drops of user created systems. It can also calculate required pressure gain from booster fan, based on pressure losses which are caused by elements in system. Verification of program is then made by comparing measured values of pressure in working system for flue gas desulphurisation. Finally, for presenting operation of program, there is calculation of pressure losses in planned FGD system.
