Energy-saving effect by 1 day-audit

(Average energy-saving rate by industry)

Case example of audit (1): Water supplying works
Problems:
  1. 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 numbf 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
