HL 350

Oil Burner Demonstrator

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 trolley. The boiler features two viewing windows 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

- Layout and operating behaviour of an oil burner
- Operation of a boiler with an oil burner
- Effect of burner setting on combustion and on the
flame
- Temperature measurements in different areas of
the combustion chamber
- Oil pressure measurements on the burner with
observation of the effects of changes on the flame
- Investigation of the effect of oil preheating on
combustion and particularly the flame
- Calculation of the thermal rating of a boiler
- Function of a plate heat exchanger
- Temperature curves in a plate heat exchanger

Features
