How to use a gas stove safely? What is the difference between a coal gas stove and a gas stove?

Human beings are the most intelligent group. For example, in cooking, which is the most common thing, we can use many different kinds of kitchen utensils, such as stoves, gas stoves, gas stoves, induction cookers, liquefied gas, etc. It is estimated that some cooking novices may not be able to distinguish them clearly. The following is a detailed introduction for you.

How to use a gas stove safely

1. First, turn the valve on the gas tank or the switch of the gas pipeline counterclockwise. If it is a gas stove with electronic ignition, press the gas stove to ignite and rotate counterclockwise to ignite.

2. For non-electronic ignition gas stoves, first light a lighter or a match, then put the flame on the stove eye, then press the gas stove ignition switch, turn it counterclockwise to on, and release the switch when the flame at the stove eye burns normally. The correct steps are ignition - release gas - place the pot,

3. Be sure to remember to close the valve on the gas tank or the switch of the gas pipeline after use.

What is the difference between a gas stove and a gas stove?

1. Different gas sources: Natural gas is a type of dry gas, with methane as the main component, no or little impurities, high calorific value, but slow flame propagation speed and high delivery pressure. Coal gas is a mixture of multiple gases, containing impurities such as moisture, oil, dust, naphthalene and hydrogen sulfide, and has a lower delivery pressure.

2. Different appearance: The appearance of gas stoves and natural gas stoves are basically the same, but there are also subtle differences, such as the different sizes and numbers of holes in the gas nozzles.

3. Different calorific values: The calorific value generated by a gas stove is 2.1 to 2.3 times that of natural gas. Under the same heating effect, the volume of natural gas consumed by a natural gas stove is less than that of coal gas.

4. Different impacts on the air: The gas produced by a natural gas stove does not contain carbon monoxide and is a non-toxic fuel gas. However, if it is used in a confined space for a long time, it may cause serious suffocation and death. The gas produced by a coal gas stove contains carbon monoxide, which is a toxic gas.

The difference between gas stove and liquefied gas stove

The gas "nozzle" has different sizes of air outlet apertures, and the natural gas stove's "nozzle" aperture is larger. Because their gas supply pressures are different, the initial "nozzles" are different and cannot be mixed.

Usually, liquefied gas has a high pressure and a small gas nozzle aperture, while natural gas has a low pressure and a large aperture. In addition, when designing stoves, people are usually concerned about the amount of oxygen in the air that supports combustion, that is, the mixing ratio. Liquefied petroleum gas requires more air, so the other two types require less air accordingly.

In terms of combustion characteristics, natural gas and coal gas are not interchangeable. Therefore, when switching from natural gas to natural gas, the original coal gas stoves, appliances, meters, and distribution pipelines must be replaced or modified. Among them, artificial gas burners should be transformed or updated to natural gas burners, and household stoves can be converted into natural gas stoves by replacing nozzles and fire hole covers. Household water heaters can be converted into natural gas water heaters by replacing nozzles (main fire, long open fire, etc.) and burners.

The working principle and appearance of natural gas stoves and coal gas stoves are similar. The difference is that the holes of the gas nozzles are different. The main reason is that the combustion calorific value of natural gas and coal gas is different, and the pressure is different. The pressure of natural gas is 2800 Pa, and the pressure of pipeline gas is 2000 Pa. Pipeline gas stoves can be changed to natural gas stoves. This process only requires changing the nozzle and fire cover of the stove.
