The support systems of Premix Gas Burners - Combustion Head and Metallic sock

Combustion Head

The premix burner is widely popular than the traditional jet burners due to the plethora of advantages it offers to industries and the environment. The primary being the process of achieving the air-gas combustion mixture. Moreover, it also depends on the technology of the combustion head. In the traditional pressure jet burners, with the help of special devices, the mixing of gas and air combustion occurs at the end of the combustion head. 

The combustion head is a primary component in the RX Burners. The air-gas combustion mixture is delivered through the ports into the combustion head. The ignition takes place through the spark generation when the mixture transits to the outer side. The gas ports' design ensures that the speed of the return flame is relatively lower than the rate of the air-gas mixture throughout the modulation range. The method avoids harmful accidents or any dangerous condition or threat to the environment.

Metallic Sock

This fundamental element of premix burners is the metallic sock. This component is specifically designed with unique alloy materials. It improves the life and overall performance of the combustion head and optimizes the resistance to thermal stress. 

  • Higher combustion intensity
  • Minimum combustion head adjustments
  • High turndown ratio
  • Prevention of incorrect combustion
  • Reduced flame noise
  • Reduced chimney noise
  • The improved thermal exchange at minimum power
  • Compact shape
  • Reduction in the dimensions of the chamber of the combustion head
  • Flexibility to work without changes with LPG gas
  • Ideal for residential applications in built-up zones
  • Enhanced design
  • Operates over minimum power
  • Minimal condensing problems

Paint Booth

Riello Gas Burners are widely used in paint booths, with the premix series allowing maximum interchange. Following are the advantages of using Riello premix gas burners for paint booth:

  • Reduced fuel consumption
  • Better temperature stability
  • 100% thermal exchange efficiency
  • No chamber
  • No chimney
  • No condensing issues
  • Quick transfer with the temperature setpoint
  • Reduced time efficiency on changing paint phase

RX Gas Burners and Types

RX gas burners include a centrifugal fan. The geometry of the fan ensures optimized speed variation, low noise emissions, and top-class performance. Some variants of RX gas burners like RX 150 contain polymer-made centrifugal fans, while other variants have centrifugal fans made of steel alloy. In addition to the centrifugal fan, the RX Gas Burner variants use brushless motors. These motors add in a lot of advantages such as:

  • Optimization of power consumption
  • Low noise
  • Compact size
  • Load modulation
  • High efficiency
  • Improved motor speed variation
  • Greatest control of power output
