Here’s our guide to the essential appliances for a cozy summer home.

In home kitchens, the energy efficiency and safety of gas stoves directly affect the cooking experience and energy consumption. LG gas stoves, with their concentrated combustion system, have achieved a dual improvement in thermal efficiency and environmental emissions through fully premixed combustion technology, infrared radiation heat transfer and intelligent control, setting a technological benchmark for modern kitchens.

1. The principle of the energy concentration combustion system

LG gas stove uses fully premixed combustion technology. Gas and air are fully mixed at 105%-130% of the theoretical air volume and then burned to form a flameless combustion state. The heat generated by combustion is converted into high-energy infrared radiation through the metal honeycomb or alloy heating element, which acts directly on the bottom of the pot. This radiative heat transfer method is more efficient and has less heat loss than traditional convective heat transfer. Nowadays, LG gas stoves have improved thermal efficiency from an early 63% to 78% thanks to their "premixed swirl core" design and infrared gas combustion technology, which enables flame temperatures up to 1000 ° C and significantly enhances thermal energy utilization. The fully premixed combustion technology also reduces emissions of harmful gases such as CO, HC and NOx through the three-way catalytic converter technology, achieving a dual breakthrough of environmental protection and efficiency.

2. Enhanced thermal efficiency

LG gas stoves have improved thermal efficiency through multiple technological optimizations. Premixed swirl cores ensure thorough mixing of gas with air, increasing combustion temperature and efficiency; The heat collection plate, made of composite material, has the functions of heat storage, heat reflection and far-infrared heating, with an average energy saving rate of 25%. After installing the cyclone, the thermal efficiency of the gas stove can be increased by 6.2%-6.4%, while the CO value in the dry flue gas is increased, but still within the allowable range of the national standard. LG gas stoves have achieved a thermal efficiency of 78% in some models through technological upgrades, which can save considerable gas costs in the long term.

3.Technical Highlights

LG gas stoves stand out in terms of technical highlights. Its "four-layer energy sink" design uses four-layer insulation technology to reduce heat diffusion and make the flame highly focused and concentrated; The U-shaped hollow air wall design of the energy-concentrating and heat-insulating disk can concentrate heat and insulate effectively. The support device is designed to accommodate cooking utensils of different shapes and sizes. By adjusting the Angle between the support block and the clamping block, the bottom of the cooking appliance is located at the outer flame of the gas stove combustion, improving the heat utilization rate. In addition, the smart timing function and flameout protection device enhance the safety of use, such as cutting off the gas supply within 0.1 seconds in case of accidental flameout to prevent gas leakage. Some models also come with a 0-99 minute smart timer, suitable for long cooking scenarios such as making soup and stewing.

4. Practical Application

In practical applications, LG gas stoves have shown significant advantages. Its high thermal efficiency shortens cooking time, such as reducing the time for stir-frying ingredients by 30%, while reducing gas consumption. In terms of environmental protection, it achieves low CO and NOx emissions. User feedback indicates that LG's gas stove's "all-steel fan design" and "flameout protection low-pressure valve" enhance safety, the all-stainless steel design is durable and aesthetically pleasing, and the powerful stove with a backplate makes the kitchen neater and more organized. In the north and most heating areas, LG gas stove's low-temperature hot water floor radiant heating design keeps the floor surface temperature stable at 24-28 ° C and the vertical temperature difference controlled at 8-12 ° C, enhancing the comfort of winter heating.

Conclusion

Precisely focus energy to control the fire and fully release the calorific value of the gas. The energy concentration combustion technology combines energy and gas conservation with high heat cooking to meet various cooking needs in daily cooking and stewing.
