BNOx burners

BNOx burners are burners for conventional boilers with a low enough level of NOx to meet Class 5 requirements.
The BNOx line Multigas burner is hyperstoichiometric and cooled with water from the heat exchanger circuit.
It is cascade-connected between the return from the system and the primary heat exchanger.

Mainly used in natural (type B) or forced (type C) draft devices, its characteristics are:

  • high heat capacity;
  • low CO and NOx polluting emissions;
  • flame modulation up to 45% of the nominal heat capacity;
  • operation with gases from families II and III;

Choice of the number of burners is made proportionately to the required heat capacity and the dimensions of the exchanger. Development and matching of the burner may be carried out in our laboratories, taking into account the particular characteristics of each individual application.
