Day Tank Furnace Pressure Control

The pressure is regulated by the inserting of plus or minus forced air in the waste gas exit pipe, after the recuperator. In this way, we can reduce or increase the speed of the waste gas and consequently the pressure inside of the furnace.
The differential pressure value coming from the furnace pressure probe is received by the pressure transmitter that transforms it in electric signal and sends it to the digital controller. The automatic digital controller manages the air quantity (electric fan speed) through an electronic inverter.

The system is composed as follows:

  • Furnace pressure probe
  • Sensor for atmospheric pressure measuring transmitter.
  • Digital controller Instrument.
  • Electronic inverter.
  • Electric fan.
  • Air Jet damper.
