In a gas fan burner, the ratio of combustion air to gas quantity can be precisely dosed. The combustion air is supplied via a fan, which means that the combustion process is less dependent on ambient conditions such as the draught of the chimney. Due to the precise dosing, the burner can be operated with a small surplus of air and thus achieves a good firing efficiency.
Gas fan burners can be used for H/L natural gas or biogas or liquefied petroleum gas. They differ in their gas connection with the gas hoses, burner settings and pressure controller.
HL 352.02 is configured to use natural gas by default.
The HL 352.02 Natural gas burner is a commercially available gas fan burner in the power range that is commonly used for residential buildings.
The HL 352 test stand can be used to measure important temperatures and pressures, which are then available for further calculations. A thermal balance can be created from the measurement data and the energy efficiency can be determined.
