Enhancing Built-in BBQ Gas Grills: Innovations in Combustion Systems and Materials

In the manufacturing of built-in BBQ gas grills, the innovation of combustion systems and core materials has become the key to technological breakthroughs. Traditional products had low thermal efficiency (generally below 60%) due to incomplete combustion, and were prone to local overheating that burns ingredients. The newly developed flameless combustion technology optimizes the burner structure and adopts honeycomb ceramic combustion plates, accurately controlling the gas-air mixing ratio at 1:10 to achieve complete combustion. Thermal efficiency is increased to over 85%, which not only shortens the cooking time (e.g., steak cooking time reduced from 8 minutes to 5 minutes) but also reduces CO emissions, complying with the national standard GB 16410-2020 for household gas stoves.​

In terms of furnace body materials, the industry has generally abandoned traditional ordinary cold-rolled steel plates and turned to 304 food-grade stainless steel integrated stamping forming technology. This process uses a CNC hydraulic press to complete the stamping of the furnace cavity and door in one go, avoiding dirt accumulation and corrosion risks caused by welding seams. After surface wire drawing treatment, the salt spray corrosion resistance is increased by 3 times, and there is no obvious rust even after 5 years of use in outdoor humid environments. Some production ends have also introduced laser cutting technology, controlling the precision of furnace components within ±0.1mm to ensure seamless fitting with cabinets during embedded installation and avoid gas leakage risks.​

The quality control link has also achieved a comprehensive upgrade. Each product undergoes three core tests: first, air tightness test, maintaining pressure at 0.1MPa for 30 minutes to ensure no leakage in gas pipelines; second, high-temperature resistance test, heating the furnace body to 600℃ and maintaining it for 2 hours to test material deformation and coating stability; third, cooking performance test, simulating the cooking process of different ingredients (steak, seafood, vegetables) to verify temperature uniformity (temperature difference must be controlled within ±5℃). In addition, automated screw tightening equipment is used in the assembly process, making the screw torque error less than 0.5N·m, further ensuring product structural stability.​

These process innovations not only improve the core performance of built-in BBQ gas grills but also expand their application scenarios. Whether for precise cooking in home outdoor kitchens or batch cooking needs in commercial places, the upgraded products can better adapt, laying a technical foundation for the high-quality development of the industry.
