Abstract. As energy and equipment costs increase, an efficient steam
system becomes more important in the overall economics of processing plant.
A linear programming model for the optimization of a steam boiler is presented
in this paper. We have developed a mathematical model for analyzing the
performance of total cost of a steam boiler. The optimal solution in the
model is the size of heat exchangers of a steam boiler which is characterized
by the lowest total costs, which consist of investment cost and cost of
coal for ten years. Investigations show that total costs might maximally
save up to 30%.

OPTIMIZACIJA PARNOG KOTLA
PRIMENOM LINEARNOG PROGRAMIRANJA
U uslovima rasta cena energije i opreme energetskih sistema optimalan rad
sistema postaje veoma bitan. U radu je prikazana optimizacija parnog kotla
primenom metode linearnog programiranja. Realizovan je matematički model
i analizirani su ukupni troškovi korišćenja parnog kotla. Rezultati optimizacije
parnog kotla su veličine njegovih grejnih površina za koje su ukupni troškovi,
koji se sastoje od investicionih troškova i troškova korišćenja goriva
za period od 10 godina, minimalni. Isptivanja su pokazala da se ukupni
troškovi mogu smanjiti do 30%.
