The invention adopting the technical scheme has the advantages of high mixing efficiency between air and gas, short flame length during the combustion and large section surface of flame.

But the short flame and high temperature of fully aerated burners conduct more heat through burners and that causes the head of burners overheat and material the size and structure of burners.

Some companies also think the new cells could be safer than batteries, which can burst into flame if short-circuited.
