The unit will be of wide interest to all those concerned with the combustion of fuels and energy conservation, from the burner maintenance technician, to research engineers. Experimental Capabilities Familarisation of the setting and operation of a commercial oil or gas burner. The Combustion Laboratory Unit is mounted on a frame, allowing easy access to the burner , controls and combustion chamber. Combustion air is provided by the integral fan, and a sensor monitors the flame, shutting the fuel valve in the event of flame failure. Gas from either an LPG cylinder stored outside the building, or from local mains supply, is fed through pipes to the connections on the frame.
Oil is supplied from portable tanks provisioned with the oil burner.
The flame burns within a stainless steel combustion chamber which is water cooled and of sufficient size to prevent flame impingement under normal conditions. Observation windows on the side of the chamber allow the flame to be observed. The combustion products leave the combustion chamber through a duct in the end remote from the burner, and are turned to discharge vertically upward. Due to high flue temperatures, an air break transition piece is supplied between the chamber duct and the main flue, to entrain cool air and so reduce flue temperature. A flue system is available as an optional extra.
