Why Metal Fiber Burners Need to Premix Gas

Metal fiber burners are increasingly used in various industries, including aerospace, automotive, and power generation. The unique structure of metal fibers provides many advantages, such as high surface area, good thermal conductivity, and high energy conversion efficiency. However, metal fiber burners require a special gas supply system that involves pre-mixing the fuel and air.

The main reason for this pre-mixing process is to avoid the hot spots and flames that occur when gas and air are mixed after entering the burner. Metal fiber burners require very precise combustion control and uniform flame patterns to achieve maximum thermal efficiency and minimal emissions. Pre-mixing the fuel and air ensures that the resulting flame is evenly distributed across the metal fiber matrix, avoiding hot spots and uneven energy release.

Another reason for premixed gas is to reduce the risk of flashback, which occurs when the flame travels back into the gas supply line. Flashback can cause serious accidents and damage the burner components. Pre-mixing the gas and air creates a more stable and consistent flame structure that reduces the risk of flashback.

Metal fiber burners also require a low-pressure drop across the burner for optimal operation. A pre-mixing system can ensure that the gas and air are supplied to the burner at the correct pressure and velocity, maximizing combustion efficiency while minimizing pressure drop and energy consumption.

In addition, pre-mixing gas and air can reduce emissions, such as NOx and CO. A homogeneous mixture of gas and air can ensure that combustion occurs at the desired stoichiometry, reducing the formation of pollutants. Pre-mixing gas also allows for greater flexibility in fuel selection, making it easier to switch between different fuels without requiring burner adjustments.

Premixed gas and air is a critical step in ensuring efficient and safe operation of metal fiber burners. By creating a homogenous mixture of gas and air, pre-mixing reduces hot spots, minimizes flashback, reduces emissions, and maximizes combustion efficiency.

RONDATEX metal fiber fabric, as a combustion medium for premixed burners, has several advantages. Firstly, its high surface area and porosity provide excellent heat transfer and combustion efficiency. Secondly, it has a stable and uniform combustion process, which can improve the stability and safety of the burner system. Thirdly, the metal fiber fabric can withstand high temperatures and harsh conditions, making it suitable for use in various industrial processes. Finally, RONDATEX metal fiber fabric is a renewable and environmentally friendly material, which can help reduce the carbon footprint of industrial processes. Overall, using RONDATEX metal fiber fabric as a combustion medium can improve the efficiency, safety, and environmental sustainability of industrial burners.
