Combustion Training & CPD

Fuel-Rich C₃H₈ Explosion

GTRC offers the necessary facilities and expertise to deliver bespoke training and CPD packages for operators, engineers, and graduates in the areas of gas turbines and combustion.  See GTRC News for recent courses we have developed and delivered.

Outlined below is a general combustion course delivered to staff in the steel industry. Other course have been developed to introduce gas turbine technology and power systems. Please contact the centre manager (morrissm@cardiff.ac.uk) if you require any further information.

 

Course Aims

 

To introduce the basic principles of combustion systems (burners, engines, explosions, gas turbines) and fundamental control parameters, particularly to raise awareness of negative impact of poorly controlled combustion.

Course Elements

 

Seminar 1 - Introduction to basic combustion & explosive risks

 

1. Introduction to basic combustion principles (flames, premix, diffusion, ignition).
2. Combustion ppplications (Domestic, ICEs, Boilers, GTs).
3. Inherent Risk & Hazard. Case studies (What can/has gone wrong) with particular attention to steam explosions.
4. Explosive limits (overview for differing fuels at different initial conditions).

 

Seminar 1 - Demonstration

 

1. Coal dust explosion rig demonstrating how much energy is contained in a small amount of pulverised coal.
2. Flammability limit demonstration rig with propane/air mixtures showing effects of fuel mixture on resulting flame.
3. Explosive demonstration of liquid fuel mists, liquid fuel jet fires and pool fires

 

Seminar 2 - Combustion mixture composition

 

1. What is required in a typical combustion mixture composition.
2. Very simplistic Chemistry explaining Air rich to fuel rich (referring back to Seminar 1 demonstration).
3. What is a Stoichiometric mixture? And why is this important (Flame speed, flame temperature).
4. Problems with the accurate control/metering of fuels and oxidants potential error.
5. Emissions (how and why are these monitored (basics)).

 

 Seminar 2 - Demonstration

 

1. Atmospheric burner methane/air, demonstrating range from diffusion to pre-mixed showing how equivalence ratio affects flame-speed (flash back & blow-off) and flame temperature. Lead into how high flow can develop into turbulence.

 

Seminar 3 - Industrial Energy Systems

 

1. Fuel and Burner types.
2. Basic insight into fuel reserves and usage (Gases, coal, etc).
3. Effect of mixing, stabilisation, ignition, pilot etc.
4. Characteristics of different fuels Cv (on a mass to volume basis) , flame-speed, stoichiometric mixes, flame temperatures with particular attention to components of COG (H₂), BFG (H₂/CO) and Natural Gas (CH₄).
5. Burning characteristics of Hydrogen and Methane flames and mixtures of. (illustrated by small scale laminar explosions) showing instability and flame speed comparisons).
6. Insight into potential fault diagnostics.

 

Seminar 3 - Demonstration

 

1. Swirl burner showing how mixing and stabilisation can be achieved for methane flames, COG and BFG.
