Here is our guide to the must-have appliances for a cozy summer home.

When you use both burners in your kitchen, have you ever noticed that one side always has a brighter flame than the other? This is not a product quality issues, but hidden in the stove design of scientific wisdom. Behind the uneven firepower is a combination of thermodynamics, fluid mechanics and ergonomics.

(1)、 difference in cooker design

In some cases, there is a difference in heat load in the design of binocular ovens. In the common design, the right oven eye has a higher heat load (e.g. 5.0-5.5 kw) , which is optimized for cooking methods that require high heat, such as stir-frying; the left oven eye is usually set with a lower heat load (e.g. 4.0-4.5 kw) , which is more suitable for stewing or soup-making. This differential design takes into account the principles of ergonomics, most people used to stir-fry with the right hand and other operations, the right side of a large fire can improve cooking efficiency. If you need to balance the fire, you can choose the symmetrical design of the stove, or at the time of purchase carefully check the product nameplate heat load parameters.

(2)、 the fire hole is blocked

In long-term use, overflowing soup or food residue is easy to be carbonized and accumulated in the fire hole of the fire cover, resulting in the reduction of the pore size. When part of the fire hole is blocked, the gas injection section is reduced, the flame may appear red and yellow disorder state, and the thermal efficiency is significantly reduced. The gas source can be closed when processing. After the cooker is cooled, the fire hole can be dredged vertically with a fine needle (the diameter of the hole is usually 0.5-1.0 mm) to avoid obliquely piercing and damaging the hole wall. For stubborn carbon stains, soak the burner cap in white vinegar solution for 10 minutes, soften and clean up. Preventative cleaning once a month can effectively reduce the probability of clogging.

(3) 、improper throttle adjustment

The throttle controls the air and the fuel gas mixing ratio, if adjusts improperly can cause the combustion not to be sufficient. If the flame turns yellow or red, indicating insufficient air, it is necessary to increase the opening of the damper. If the flame spreads or produces noise, the opening is too large, it is necessary to reduce the opening. Ideally, the flame should be a uniform blue cone with the outer flame sticking to the bottom of the pan. Need to note that the adjustment should be carried out in a slightly dark environment, easy to observe the flame shape, and avoid empty fire adjustment, it is best to place the pot for daily use.

(4) 、component aging and usage habits

More than three years of use of the stove may appear nozzle wear or gas aging and other issues. After the nozzle diameter is expanded due to the erosion of gas impurities, the gas flow rate increases, which may lead to fire out of control. In addition, the use of habits such as excessive use of detergent foam, unequal placement of pots, will also affect the stability of the fire. In daily use should avoid hose bending, ensure that the cooker level, and regularly check the interface is leaking.

(5)、solutions and preventive measures

1. Regular cleaning and maintenance: clean the outlet of the burner cover monthly to prevent clogging; check the status of the hose regularly to ensure that there is no aging or cracking.

2. Correct throttle adjustment: adjust the throttle according to the type of gas source (natural gas or Liquefied petroleum gas) to ensure adequate combustion.

3. Rational use of habits: to avoid the overflow pot immediately after the flameout, timely cleaning after cooling; to ensure that the bottom of the pot dry, prevent water vapor caused by fire hole corrosion.

4. Professional maintenance time: if the problem still exists after adjustment, or involves damage to internal parts, should contact professionals to repair.

Conclusion

The fire stability can be improved effectively by understanding the multiple causes of the uneven fire of the binocular cookers and taking targeted measures. Routine maintenance and proper use are key, and complex problems require timely professional help to ensure safety and effectiveness.
