【Q&A Question 058】June 17, 2016: What is the reason why the flame flutters weakly? The answer key will be available after responding; scoring is based on addressing the key points. The flame is weak and flickering because there is insufficient air flow, resulting in incomplete combustion; the primary and secondary air valves should be opened wider.
Low oxygen content; high negative pressure in the furnace chamber
The weak and flickering flame is due to insufficient air supply; the primary and secondary air valves should be opened wider.
Due to insufficient air volume, combustion is incomplete; therefore, the primary and secondary air valves should be opened wider.
Large air volume, small fuel volume, low pressure
The flame is weak and flickering due to insufficient air supply; the primary and secondary air valves should be opened wider.
