1, the use of different fuels:

Natural gas stove with natural gas, artificial gas;

Liquefied petroleum gas stove with liquefied petroleum gas;

2, different calorific value:

Liquefied petroleum gas has the highest calorific value (12,000 calories / cubic meter), so it is the most fine air outlet, about 0.5 ~ 1 mm;

Natural gas calorific value of the middle ( 8000 calories / cubic meter) it is 2 millimeters;

Artificial gas calorific value of the lowest (national standard: not less than 3400 calories / cubic meter), so it is the largest outlet of about 2.5 ~ 3 millimeters.

3, the pressure is different:

Liquefied gas pressure is high, natural gas pressure is low, specifically reflected in the stove, that is, the liquefied stove on the nozzle diameter is smaller than the diameter of the natural gas stove nozzle, so the two types of stoves can not be directly common.

4, the composition of different:

Natural gas is the main component of methane, combustion needs less natural gas, need more air, so it's smaller outlets, while the air inlet is larger; liquefied petroleum gas is the main component of carbon more hydrocarbons and alkenes, combustion and methane is just the opposite, so it is a larger outlets.

Expanded information:

Natural gas cooker most of the installation of automatic flame failure protection device, flame failure protection device is when the gas cooker meets the accidental flame failure to shut off the gas valve automatically a safety protection mode. Safety protection, such as the wind will blow out the fire or cooking rice overflow will be doused with fire and other circumstances, flame failure protection device will close the gas valve to prevent a large number of gas leakage into the room caused by poisoning or fire accidents.

The working principle: when the knob is pressed and the small fire is ignited, the thermocouple is heated by its flame and generates thermal potential. Thermoelectric potential through the wire into the electromagnetic coil, generating a magnetic field so that the solenoid valve suction, gas valve open;

Combustion pathway open, to maintain its normal combustion, once encountered a gust of wind or soup and other overflow, extinguish the flame, thermocouple thermal potential quickly drop to zero, the coil is de-energized, the solenoid valve is disabled, the role of the spring quickly reset, the valve closes the gas pathway, terminate the supply of gas, to ensure the safety.

Natural gas is the best gaseous fuel, high calorific value, complete combustion, less impurity content, combustion produces very few pollutants. The use of liquefied petroleum gas is not convenient, especially for large users of transportation and storage difficulties, incomplete combustion, combustion products and incomplete combustion will cause pollution and so on.

Now many local gas use gradually by liquefied petroleum gas to natural gas. In response to this change, the general business has long been ready to spare parts to facilitate the use of gas conversion.

And we can look at the logo on the stove when you buy, well-known brands and regular manufacturers, the production of natural gas stoves labeled with "T";

Liquefied petroleum gas stoves with "Y". In addition, from the stove's air outlet can also be seen, the highest calorific value of liquefied petroleum gas (12,000 calories / cubic meter) so it is the thinnest air outlet, about 0.5-1 mm; natural gas calorific value of the middle (8,000 calories / cubic meter) its air outlet for 2 mm. Consumers can choose the right brand of gas stove according to their own habits and related gas facilities.
