Abstract. In a tool shop, different boilers may provide heat needed
by space heating and hot technology. We try to conserve energy by using
design solutions with recovery-heat exchangers and optimal sizes of heat-transfer
surfaces of boilers. As an optimization methodology we have used sequential
linear programming (LP). The LP-objective functions have been the minimum
energy and money expenditures. After a design optimization of energy system
of our example-tool shop we will have an energy saving up to 5%, and money
saving up to 14%.
UTICAJ KOTLOVSKIH RAZMENJIVAČA ZA ISKORIŠćENJE
OTPADNE TOPLOTE
NA VELIČINU KOTLOVA - PRIMER HALE SA PRESERSKIM
ALATIMA
U industrijskoj hali sa toplim preserskum alatima različiti kotlovi obezbedjuju
zagrevanje hale i energiju potrebnu za realizaciju tehnoloških postupaka.
Mi smo pokušali da metodom sekvencijalnog linearnog programiranja izvršimo
racionalizaciju potrošnje energije projektovanjem više izmenjivača toplote
i optimiziranjem veličine površine za razmenu toplote kotlova. Ciljna funkcija
metode linearnog programiranja je bila minimalna potrošnja energije sistema
i minimalni ekonomski troškovi rada sistema. Po izvršenom optimiziranju
energetskog sistema industrijske hale sa preserskim alatima mi smo dobili
mogućnost 5% uštede energije i 14% uštede troškova rada sistema.
