What are the three elements of the fire triangle required for combustion?
Answer: Fuel, oxygen, and heat
Combustion requires fuel, oxygen, and heat — the three sides of the fire triangle — and all three must be present simultaneously.
What are the primary byproducts of complete combustion of a carbon-based fuel?
Answer: Carbon dioxide and water vapor
Complete combustion of carbon-based fuels produces carbon dioxide (CO₂) and water vapor (H₂O) as the primary byproducts.
What combustion byproduct is most dangerous because it is odorless and colorless?
Answer: Carbon monoxide (CO)
Carbon monoxide is the most dangerous combustion byproduct because it is odorless, colorless, and can cause fatal poisoning without any sensory warning.
What most commonly causes incomplete combustion in a wood-burning fireplace?
Answer: Insufficient air supply
Insufficient air supply leads to incomplete combustion, producing carbon monoxide, creosote, and smoke instead of fully oxidized flue gases.
What flue gas temperature range indicates efficient combustion in a wood stove?
Answer: 300°F to 700°F (149°C to 371°C)
Optimal wood stove flue gas temperatures of 300°F to 700°F indicate efficient combustion while avoiding excessive creosote formation from too-cool gases.
Which type of combustion produces the most creosote in a chimney?
Answer: Slow, smoldering combustion with restricted air
Slow, smoldering fires with restricted air supply produce the most creosote because unburned hydrocarbons condense on the cooler flue walls.
