Värnamo, Boiler 1
Mounting of an AEROVIT system August 2005
Before the boiler had to be cleaned every 6. week. The flue gas temperature was on a clean boiler 210°C. The manual cleaning was executed by 250°C
Evaluation of the AEROVIT systems effect
From 28 Nov. 2005 to 28 April the boiler is running full load. In that period the flue gas temperature increased by 30°C.
Without AEROVIT: Manual cleaning 6 times/year.
With AEROVIT: Manual cleaning 1 time/year
With 1% savings on fuel consumption and increased boiler efficiency and with 60% fewer manual cleanings the result will be:
The investment DKK 273.000 is paid back after 16 months. Rate of return/year at average: 77 %
