Burners of HPN-TeR type „ULTRA LOW-NOX“

Burners of HPN-TeR type belong to a group of special burners. They are burners which are constructionally connected to relevant technological equipment. They are used mainly for heating of industrial tube furnaces and combustion chambers, especially on the field of chemical and petrochemical industries. 

Burners of HPN-TeR type are combined oil-gas burners with a manual control, with flame stabilisation provided by means of a gas injector stabilisation burner, with an internal exhaust-gas recirculation and with a forced intake of combustion air. The stabilization burner is equipped with a trigger electrode which serves simultaneously as a monitoring electrode for connection to an electro-spark ignition and monitoring device. Burners serve for the combustion of heating gases, gaseous and liquid fuels of refinery origin and for the combustion of fuel oils. In the case that the oil burner is not installed, these burners are marked as gas burners of HN-TeR type. In case a gas burner is not installed, these burners are marked as oil burners of HP-TeR type.

1) The capacity value is only illustrative.

2) The values are given for the temperature of combustion air 20 °C.

3) 5) Fuel pressure values are stated for natural gas. This specification is informative; when using different types of fuels and other burner powers, particular values will be stated in technical specifications of the burner. When using a burner for lower fuel pressure value, it is necessary to count with lowered maximum burner power with limited regulation range.
