Morphology

pyrogen = pyro + gen

The literal 'fire-producing' interpretation is close to the component meanings, but the noun is a specialized technical term for a highly flammable substance.

Etymology

Pyrogen combines pyro- 'fire' and -gen, like in generate, 'to make'. So a pyrogen is something that 'makes fire' and is used for materials that catch fire easily or burn quickly.
