Problems:

l. Aeration fan is uncontrollable.
2. Fluidized bed incinerator is inefficient.

Improvement measures:

1. Aeration fan- It is inappropriate to use an inverter. (Investment in the inverter to control three units of aeration fans simultaneously so as to avoid wind pressure change is too costly.) The problem was solved by the combination of interval operations and the control of the number of units.

2. Increase the efficiency of fluidized bed incinerator by using regenerative burner
- A pair of burners, which are unified with a heat regenerator for preheating, burn alternately in a short cycle.

Effect: Power - 1,200MWh/year, Oil - 293kL/year, Total -12.4% reduction
