LLM classification basis: function-based → ≡
The concept is defined by its identity-giving function: inducing chemical reactions through heating. Both definitions focus on the process/activity ('induce a reaction') rather than structural mechanisms, making this primarily functional classification.

Identity-Giving Function
✓ done
ReactiveHeatingFunction → ReactiveHeatingProcess ⊑ HeatTransfer
▼
COPI-Core operation
HeatTransfer via process parent HeatingProcess
LLM rationale:
The identity-giving function is to induce reactions in process fluids through heating. This is more specific than general heating (which only adds thermal energy) - it combines heating with the intended outcome of chemical transformation. This function is a subtype of HeatingFunction since it includes heating as the mechanism but adds the specific purpose of reaction induction.

Genus Proximus

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
ISO 15926 explicitly states 'A <FURNACE> is a <HEATER>', making heater the direct genus. The heater class is already enriched in our ontology with HeatingFunction. This follows the Aristotelian principle of choosing the most specific appropriate superclass rather than jumping directly to Assembly.

Furnace
from sibling classes under genus
Heater.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The differentia is the reactive heating function - the capacity to induce chemical reactions through controlled heating. This distinguishes furnaces from other heaters like boilers (which cause phase change) or simple heaters (which only add thermal energy without reaction intent).

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These parts are universal to all furnaces regardless of specific design (forced draft, natural draft, horizontal, vertical, etc.). The combustion chamber provides the heating, and process fluid pathways enable the fluid to be exposed to the reactive heating environment.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Furnaces transform input process fluids through thermal-induced chemical reactions while consuming fuel to generate the required heat. The key transformation is chemical reaction rather than just thermal energy addition.
