Chemical process releasing energy as heat and light

Three requirements for combustion

Fuel, oxygen, energy

Complete combustion oxygen supply

Plentiful supply of oxygen

Complete combustion products

CO2\text{CO}_2 and H2O\text{H}_2\text{O} only

Complete combustion flame colour

Clean, blue flame

Incomplete combustion flame appearance

Yellow, smoky, or sooty flame

Carbon monoxide toxicity mechanism

Binds to haemoglobin, preventing oxygen transport

Heat of combustion

Heat released when substance burns completely in oxygen
