The gas stove is developed for the Chineseculinary market. It uses the industry’s pioneered semi- closed cohesive flamecombustion technology, with a thermal efficiency of up to 75% that is far morethan the national level-1 energy efficiency (63%), it saves more gas on a year-on-year basis. Its heating area is designed to be a “crater” shape, improvingthermal efficiency, reducing heat loss and preventing the flame from lickingout of the stove to reduce the user’s fear of the flame. The design of “crater”shape gives the product good strength and makes its surface bright, clean andsmooth, and is easy to clean.
