Techno-economical Analysis Method of Energy Consumption in Cigarette Production and its Application

For tapping the potential in energy conservation in cigarette production, a techno-economical analysis method of the energy consumption based on material quantity input-output analysis was proposed,and the energy consumptions of three cigarette enterprises were analyzed at different levels. The results showed that:1) The major factors affecting the comprehensive energy consumption of the enterprises were energy type and regional climatic conditions. 2) Main production system and auxiliary production systems accounted for more than 90% in total energy consumption,primary processing line accounted for 78%-94% of the energy consumption of main production system, and boilers and air conditioners accounted for 90% of that of auxiliary production system. 3) The energy consumption per unit output of expanded cut tobacco was 5 times the consumption of cut stem or cut tobacco. It was concluded that using high efficiency boiler and air-conditioning system, and improving the working efficiency of equipments were the key points for energy saving in cigarette enterprises.
