Abstract

Energane na otpad su postrojenja u kojima se spaljuju različiti tipovi otpada, u ovome radu analiziran je sustav za suho čišćenje dimnih plinova za energanu koja godišnje spaljuje 60000 t goriva dobivenog iz otpada. Na temelju odabranog sastava goriva postavljene su bilance dimnih plinova i izračunate su potrebne količine aditiva za neutralizaciju kiselih plinova i uklanjanje teških metala i organskih spojeva. Neutralizacija kiselih plinova vrši se pomoću sode bikarbone čija potrošnja je procijenjena na 118,6 kg/h, a za uklanjanje teških metala i organskih spojeva troši se 6,2 kg/h aktivnog ugljena. Glavna komponenta sustava za čišćenje dimnih plinova je vrećasti filtar te je za njega izrađen proračun na temelju kojeg je dobivena potrebna površina za filtraciju od 1900 m2 i odabran je materijal vreća od politetrafluoretilena (PTFE). Izrađena je shema cijelog sustava za čišćenje dimni plinova te je odabrana glavna oprema i detaljno je opisan princip rada. Zadnji dio rada obuhvaća proračun izmjenjivača topline snage 1161,4 kW koji se koristi za regeneraciju topline dimnih plinova nakon procesa čišćenja.

Abstract (english)

Waste-to-energy plants are facilities where various types of waste are incinerated. This paper analyzes a dry flue gas cleaning system for a waste-to-energy plant that annually burns 60,000 tons of fuel derived from waste. Based on the selected fuel composition, flue gas balances were established, and the necessary quantities of additives for neutralizing acidic gases and removing heavy metals and organic compounds were calculated. The neutralization of acidic gases is performed using sodium bicarbonate, with an estimated consumption of 118,6 kg/h, while 6,2 kg/h of activated carbon is used to remove heavy metals and organic compounds. The main component of the flue gas cleaning system is a bag filter, for which a calculation was made, resulting in a required filtration area of 1900 m², and bags made of polytetrafluoroethylene (PTFE) were selected. A schematic drawing of the entire flue gas cleaning system was created, and the main equipment was selected, with a detailed description of the operating principle. The final part of the paper includes the calculation of a heat exchanger with a capacity of 1161,4 kW, which is used for heat recovery from flue gases after the cleaning process.
