Axiomatization Decision Log
1
Identity-Giving Function
Function class
FiredHeatingFunction
⊑ HeatingFunction
Realized in
FiredHeatingProcess
⊑ HeatingProcess
The identity-giving function is the conversion of chemical energy from burning fuel (solids, liquids, or gas) into thermal energy that is transferred to a process fluid. This distinguishes fired heaters from other heating equipment that uses electrical energy, steam, or hot oil as the heating medium.
2
Genus Determination
Heater
The parent_candidates list does not include 'heater' but the already-enriched classes show that 'heater' exists with HeatingFunction and Assembly genus. Both ISO 15926 and the natural classification hierarchy confirm that fired heater is a subtype of heater. This is the most specific appropriate genus - more specific than 'heat transfer equipment' and correctly captures the shared heating function.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These parts constitute the minimal necessary components for any fired heater: a combustion space, fuel burning device, heat transfer surface, and exhaust system. Specific configurations vary by subtype but these elements are universal.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— process fluid to be heated
PortionOfFluid
— fuel (gas, liquid, or solid)
PortionOfFluid
— combustion air
Outputs (O)
PortionOfFluid
— heated process fluid at target temperature
PortionOfFluid
— combustion products/flue gas
Transformation (T)
chemical energy from fuel combustion converted to thermal energy and transferred to process fluid
Signature reflects the fundamental process: fuel and air combine in combustion to heat a separate process stream, with flue gas as exhaust. This distinguishes from direct heating where combustion products mix with the heated fluid.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Cross-Standard Observations
ISO 15926 provides broader scope including all fuel types, while CFIHOS specifically mentions liquid heating without vaporization. Both agree on the core fuel combustion principle. The CFIHOS definition may be more restrictive, potentially excluding fired heaters designed for vaporization.
