It is necessary to introduce energy cascade systems into the industrial sector in Japan. The aim of this study is to evaluate the energy conservation potential of introducing both energy cascade networks and thermal recycling systems in industries located around urban area. The following industries are thought to be connected to an integrated energy center: rolling copper, printing, bakery, integrated circuit, pharmacy, dairy and refrigerated warehouse. The authors have developed an energy cascade model based on linear programming so as to minimize the total fuel consumption.
Simulation results clearly demonstrate remarkable effectiveness of the energy cascade systems. Energy cascading saves up to 22% of energy demand in the above mentioned sectors. Co-generation systems can enhance energy cascade systems because they supply both heat and electric power at the same time. Increasing the amount of garbage combustor waste heat can reduce electric power for. the turbo refrigerator by promoting waste heat driven ammonia absorption refrigerator.
