The Combustion Laboratory Unit is mounted on a frame, allowing easy access to the burner , controls and combustion chamber.
The package burner starts with an air purge, ignites its appropriate fuel (oil or gas) and automatically sets to a safe firing condition. Combustion air is provided by the integral fan, and a sensor monitors the flame, shutting the fuel valve in the event of flame failure. Air/fuel ratio and fuel firing rate can then be varied by the user.
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.
A water cooled gas sampling probe and thermocouple probe allow conditions within the flame to be investigated.
The unit allows similar locally supplied automatic package burners of up to 150kW to be operated and analysed.
A frame mounted burner training unit comprising a 450 dia x 1000m cylindrical water-cooled stainless steel chamber in which either an oil or gas burner can be fired, and the flame observed through four 100mm dia windows.
Internal electric and mechanical safety devices allow for supervised operation by students. Instrumentation to measure the water, air and exhaust temperatures, and flow rates of the cooling water, air and fuel. A hand held gas analyser supplied measures flue gas O2 content and also displays combustion efficiency, excess air, and CO2 content.
Smoke Number can be determined for the oil burner with the Smoke Tester supplied.
Further flue gas analysis including CO, NO and SO2 can be performed on either burner by using the additional optional high specification Gas Analyser.
Oil or Gas Burners up to 150kW can be used in the chamber.
Supplied with a detailed experimental operating and maintenance manual giving example experimental results and sample calculations.
