Tenders are invited for Gas turbine flame tube
repair/rectification work at gtps, Uran.
In view of this, the present article proposes to identify the hazards present in the operating phase of flame tube
boilers of the University Hospital of Santa Maria (HUSM) with the use of Failure Mode and Effects Analysis (FMEA) tool.
If the compressed air flows into the flame tube
without being decelerated, it may cause serious problems on combustion stability and high total pressure loss.
Taking the 3D solid model of loop-type flame tube
of combustor of a certain type triaxial gas turbine as reference, a 2D axisymmetric model is built by the way of area average, and the discrete computational domain is also built on the basis of structured grid.
 generally correspond to ideal combustion conditions, which are traditionally determined for upward flame propagation in a large diameter vertical flame tube
. Under other conditions, where wall chilling effects, propagation in directions other than vertically upwards and other impediments are present, combustion is hindered and this narrows the observed flammability limits compared to the published values.
Following the initial performance runs the first engine was dismantled, the coated components were installed and six windows were mounted on the engine enabling optical access to the main hot end components including the combustion chamber inner flame tube
, nozzle guide vanes and the turbine rotor blades.

Science pavilion organiser Robin Wheldon-Williams said: "Also known as the standing wave flame tube
, or simply flame tube
, is a physics experiment demonstrating the relationship between sound waves and sound pressure.
A sonic nozzle at the top of the flame tube
allows pressure in the vessel to be raised while maintaining the throughput of reactant gas.
The buring velocities of R-152-air flames recently have been measured using both the flame tube
method (Jabbour and Clodic 2004) and the spherical bomb technique, with both pressure rise and flame imaging used to extract the burning velocity (Takizawa et al.
Heater has a top mounted gas burner that fires downward through a centrally located flame tube
. The resulting heat from the flame heats the falling water, which comes in contact with the bed of packing rings where heat transfer occurs.
NASA engineers were understandably thrilled when two of their concepts met the standard in idealized "flame tube
" tests, which mimic aspects of the conditions in a combustor.
