#1 your facts are wrong. Where did you get them?
hydrocarbon fires do not reach those temperatures
There is fairly broad agreement in the fire science community that flashover is reached when the average upper gas temperature in the room exceeds about 600°C. Prior to that point, no generalizations should be made: There will be zones of 900°C flame temperatures, but wide spatial variations will be seen. Of interest, however, is the peak fire temperature normally associated with room fires. The peak value is governed by ventilation and fuel supply characteristics [12] and so such values will form a wide frequency distribution. Of interest is the maximum value which is fairly regularly found. This value turns out to be around 1200°C, although a typical post-flashover room fire will more commonly be 900~1000°C. actual fact, no jurisdiction demands fire endurance periods for over 4 hr, at which point the curve only reaches 1093°C.

This is a list of flame temperatures for various common fuels. Adiabatic flame temperatures for common gases are provided for air and oxygen. For these values, the initial temperature of air, gas and oxygen are 20 °C. MAPP is a mixture of gases, chiefly methyl acetylene and propadiene with other hydrocarbons.
Flame Temperatures
Fuel Flame Temperature
acetylene 3,100 °C (oxygen), 2,400 °C (air)
blowtorch 1,300 °C (2,400 °F, air)
Bunsen burner 1,300-1,600 °C (2,400-2,900 °F, air)
butane 1,970 °C (air)
candle 1,000 °C (1,800 °F, air)
carbon monoxide 2,121 °C (air)
cigarette 400-700 °C (750-1,300 °F, air)
ethane 1,960 °C (air)
hydrogen 2,660 °C (oxygen), 2,045 °C (air)
MAPP 2,980 °C (oxygen)
methane 2,810 °C (oxygen), 1,957 °C (air)
natural gas 2,770 °C (oxygen)
oxyhydrogen 2,000 °C or more (3,600 °F, air)
propane 2,820 °C (oxygen), 1,980 °C (air)
propane butane mix 1,970 °C (air)
propylene 2870 °C (oxygen)
