Radiant Heat: Why Fire Jumps the Gap Between Buildings
Convection burns up; radiation burns across. How radiant heat, the T⁴ law, and view factors decide whether fire ignites the house next door.
🔥 Fire Fundamentals
Combustion, flames, pyrolysis, and heat transfer.
The t-Squared Fire: How Fire Growth Rate Shapes Escape Time
Slow, medium, fast, ultrafast: how the t-squared curve turns fire growth into numbers, and why modern fuels outrun its four classes.
How Hot Is Fire? Adiabatic Flame Temperature vs Reality
Fire has no single temperature. The adiabatic flame temperature sets a 1,950 °C ceiling, yet real fires burn at 800–1,200 °C. Here is why.
Smoldering vs Flaming: The Fire That Kills You in Sleep
A smoldering fire shows no flame and little heat, yet it loads a house with carbon monoxide for hours while you sleep. Here is the chemistry that kills.
Smoke Inhalation: Why the Upper Layer Kills You First
Smoke inhalation kills more fire victims than flame does. Here is the toxic upper layer, the CO and HCN dose, and the FED clock that times your escape.
The Science of Pyrolysis: How Heat Unmakes Everything
Pyrolysis — heat breaking molecular bonds without oxygen — drives wildfires, battery thermal runaway, biochar, plastic recycling, and even coffee roasting.
