What kind of gas is used in general fierce fire stoves?

The gas used by fierce stoves and ordinary stoves is the same, both of which are natural gas.

The difference between them is that the aperture of the focal eye is different. Ordinary household stoves have small ventilation aperture and soft flame; However, the ventilation aperture of the fierce fire stove is large, and the amount of gas passing through is large, so the flame is fierce.

Generally, families don't need strong fire stoves. Usually only in professional restaurants, when cooking, strong fire stoves will be used.
