The gas hole is the key channel for gas to enter the burner. The dimensions of these small holes are carefully designed to achieve the desired gas flow. Every gas stove has specific design parameters, including the desired amount of heat production and combustion efficiency. The size and number of gas holes are adjusted according to these parameters to ensure proper combustion.
The size of the gas hole directly affects the gas flow rate. Smaller holes cause the gas to flow faster, creating an area of lower pressure that draws ambient air into the mix. By controlling the flow rate and pressure of the gas, the gas holes help ensure that the gas is mixed with the air to support efficient combustion.
2. Venturi Tubes:
A Venturi is a unique tube whose shape changes cause changes in gas flow rate and pressure. The generally narrow inlet section of such pipes causes the gas to accelerate, thereby reducing the gas pressure. This process creates an area of low pressure, triggering the effect of air being drawn in from the surrounding environment.
The design of the Venturi tube allows the gas to fully mix with the air before entering the combustion zone. This mixing helps to eliminate uneven combustion and prevent flame instability, thereby increasing the efficiency and performance of the stove. By maintaining the proper air-to-gas ratio, the Venturi ensures optimum combustion.
