Combustion Laboratory Unit (SMT-HT-32)
In 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, or 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
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.
