HL 350 Oil Burner Demonstrator Show data sheet (pdf file) Print page
Technical Description

  The unit is equipped with an oil burner. The oil pressure at the burner, the combustion chamber temperature, measured with a thermocouple, and the preheat temperature of the oil are indicated on an additional digital measuring unit. A small oil tank is fitted on the lower shelf of the frame.

  The heating boiler features a viewing window for observing the flame. The heat generated can be dissipated using a plate heat exchanger and additional cooling water connections, enabling the unit to be operated continuously.
  The exhaust gas can be studied in detail with the exhaust gas analyser HL 860.

 
Learning Objectives / Experiments
