ETC6083 Oxygen Trim Option

Our ETC6083 Oxygen Trim interface and software allows an oxygen probe to be added to the ETC6000 Burner Management System or the ETC6100 Air Fuel Ratio Controller

By monitoring the oxygen level in the exhaust gas flue, fine adjustments can be applied to the  air fuel ratio to compensate for combustion variables such as barometric pressure change, air humidity, variances in fuel quality etc. This continual compensation reduces inefficiencies.

The oxygen trim option allows the combustion system to become a true closed loop control system by reacting to the changes in combustion variances instantly. Without oxygen trim any inefficiencies will only be identified when the combustion system is checked during routine maintenance, using a flue gas analyser, or when smoke is detected emanating from the stack.

The benefits of utilising oxygen trim are not only financial but can also be measured in terms of maintenance downtime and potential damage to the boiler itself.

Features

The ETC6083 Oxygen Trim offers numerous features:

  • No moving parts
  • No pumped reference air is required
  • Stainless steel construction
  • 6 micron sintered stainless steel filter
  • Suitable for flue gas temperatures up to 540°C/1000°F
  • Intuitive automatic trim set-up reduces commissioning time
  • Assignable oxygen and temperature alarm limits
  • Boiler efficiency & calculated CO2 can be displayed and retransmitted
 

Benefits

Oxygen trim added to electronic combustion control offers benefits including:

  • Up to 3.5% fuel savings
  • Reduced CO2 emissions
  • Optimisation of air fuel ratio to compensate for variables such barometric pressure, humidity, gas pressure
  • Improved boiler efficiency and reduced maintenance and downtime (due to less deposits on boiler tubes)
  • Extended boiler lifespan
  • Integrated thermocouple
  • Range of probe sizes covering flue sizes from 0.3m to 4.0m across
  • Exceptionally quick response time
  • Adaptive trim algorithm can cope with continually modulating burners
