There are many varieties of gas stoves on the market today, with both good and bad quality. How can we choose an economical, safe, reliable and practical gas stove? Consumers should have some knowledge about gas stoves.

1. First of all, the type of gas stove selected should be suitable for the local gas source. Gas is roughly divided into three categories: liquefied petroleum gas (Y), artificial coal gas (R), and natural gas (T). These three types of gas have different calorific values ??and gas pressures. If the type of stove does not match the gas, danger will occur. , so stoves suitable for different gas sources must not be mixed. Before choosing a stove, first, distinguish the type of gas.

2. Packaging and labeling should be complete. The packaging should be marked with the factory name, address, model, etc., and each stove should have a certificate and instruction manual. There should be a nameplate on the side panel of the stove, with the name of the manufacturer, model, applicable gas and pressure, heat flow rate, production date, etc. marked on the nameplate.

3. Appropriate heat flow. The greater the heat flow value designed for household gas stoves, the stronger the heating capacity, which is what is usually called a fierce fire. Generally, consumers are willing to choose high-fire stoves. In fact, the size of the heat flow should be compatible with the cooking method and the stove. If you blindly pursue a large heat flow, it will greatly reduce the thermal efficiency of the stove and increase the amount of waste gas emissions.

Relevant considerations when purchasing a gas stove

4. Appearance quality. The stove should be beautiful and elegant. Press the handle of the countertop with your hand and there will be no obvious warpage. Hold the two opposite corners of the stove with your hand and twist it back and forth. There will be no obvious deformation of the stove. Tinplate must not be used as panel material (magnet adsorption can be used to distinguish tinplate and stainless steel materials). The stove head and fire cover should be processed finely without obvious burrs.

5. Air tightness. If the air tightness of the stove fails, it is a fatal flaw, which is the biggest hidden danger of accidents. The simple test method is as follows: connect the air source, close the knob, and brush the pipeline, valve body and interface with soap liquid until there is no gas leakage.

6. Ignition switch. The on (ON), off (0FF) and low fire positions are accurately marked. When the electronic ignition switch is pulled, the sound is crisp and powerful, and the fire point is blue and clear. If the switch is soft and the sound is muffled when ignited, it is of poor quality. The service life of a qualified ignition switch is more than 6,000 consecutive times, and the air tightness of the cock is still qualified, while the life of an inferior igniter is only 2,000 times. Qualified products must be ignited 10 times continuously, the number of ignitions must not be less than 8 times, and all fire holes must be spread within 4 seconds.

7. Flame burning state. It is an important reflection of the combustion quality of the stove. After igniting, adjust the damper to produce a clear, light blue flame without producing yellow flame, black smoke, backfire and other incomplete combustion phenomena. These phenomena directly affect the thermal efficiency of the stove and the quality of the flue gas. Turn off the air source and keep a small flame with 1/3 of the height of the normal flame. It can still burn normally without extinguishing or tempering.

8. Weigh the portions. Weigh the stove with your hands. Products that meet the standards have sufficient weight due to the use of high-quality materials. Inferior stoves are lighter in weight due to their thin material.
