3.3.2 In-plant energy consumption in the 35 WTE plants
In order to investigate the Korean WTE in-plant energy loss and/or use per ton of MSW, the
slope of the line was derived based on the data from table 9. The average energy consumption in the 35
WTE plants in 2010 was 0.67 MWh of thermal energy per ton of MSW as shown in Figure 30.
Because a portion of energy or heat is initially lost from a furnace by the ash, designing a
furnace is very important to reduce energy and heat losses. However, this applies to a future plan on
building a new WTE facility. For the existing plants, the facilities can minimize the in-plant use and/or
loss of the primary energy generated from the plants by installing new equipments and also by
improving on their operation. For example, less combustion air during start up and shut down may
lower the loss of energy.
