Industrial Gas Burners & Boiler Parts | Durable, Low-NOx Solutions

Stiefel, founded in 2013 and based in Guangzhou, China, is a trusted supplier of high-quality natural draft gas burners, efficient combustion systems that rely on natural air flow (created by buoyancy) to supply oxygen for gas combustion, eliminating the need for mechanical blowers and reducing energy consumption in residential, commercial, and light industrial applications. A natural draft gas burner uses the upward flow of hot exhaust gases to draw in fresh air through vents or chimneys, creating a self-sustaining combustion process that is simple, reliable, and cost-effective, making it ideal for water heaters, space heaters, and small boilers where complex ventilation systems are impractical. Stiefel's natural draft gas burner features a carefully designed combustion chamber and venturi tube that optimizes air-gas mixing, ensuring complete fuel combustion with minimal emissions of CO and NOx, which is essential for complying with safety standards and maintaining indoor air quality in residential settings. The natural draft gas burner is constructed with durable materials such as cast iron, stainless steel, and heat-resistant ceramics that withstand the high temperatures of gas combustion (up to 1,600°C), ensuring long service life and minimal maintenance, even with continuous use. What sets this natural draft gas burner apart is its simplicity of design, with fewer moving parts than forced-draft burners, reducing the risk of mechanical failure and lowering repair costs, which is particularly valuable for homeowners and small businesses with limited maintenance resources. Natural draft gas burners from Stiefel are available in various sizes (from 10,000 BTU to 200,000 BTU), supporting applications ranging from small kitchen stoves to mid-sized commercial water heaters, and are compatible with natural gas and propane, offering flexibility for different fuel sources. Equipped with safety features such as flame failure sensors and pressure regulators, the natural draft gas burner automatically shuts off gas flow if the flame is extinguished, preventing gas leaks and ensuring safe operation in enclosed spaces. Rigorously tested for combustion efficiency, draft strength, and safety, these natural draft gas burners meet international standards such as ANSI Z21.1 and EN 267, ensuring compliance with global regulations for gas-fired appliances. Backed by Stiefel's expertise in research and development, the natural draft gas burner incorporates innovations such as improved venturi designs and precision gas orifices that enhance air-fuel mixing, increasing efficiency and reducing fuel waste, aligning with the company's commitment to energy-saving solutions. With Stiefel's comprehensive service network, customers receive expert support for selecting, installing, and maintaining natural draft gas burners, including guidance on proper vent sizing and placement to ensure adequate draft and optimal performance. For applications seeking reliable, low-maintenance gas combustion, Stiefel's natural draft gas burner is a practical solution that delivers efficiency, safety, and simplicity.
