XRQ-21 series gas burners are mainly designed for medium and high pressure gas, combustible natural gas, coke oven gas, blast furnace gas, city gas, liquefied petroleum gas, mine gas, generator gas, etc. The burner mainly consists of a burner body, a stable combustion hood made of heat-resistant steel, a damper regulating mechanism, an explosion-proof ignition device, an ignition nozzle, a heat-resistant steel gas nozzle, a flame detector, and a fire observation hole.

This series of burners adopts fuel staged combustion, which not only can adjust the flame shape, but also can adjust the thermal load in a wide range. Combined with staged air supply technology, low NOx combustion can be achieved. Not only is the combustion efficiency high, but also the emission of pollutants is minimized. Widely used in power generation boilers, industrial boilers, hot water boilers, fluidized bed boilers, heating furnaces, incinerators, hot air furnaces, kilns, etc.

Technical features:

◆ High injection speed at the flame outlet, strong flame rigidity, and wind resistance up to 60m/s;

◆ Structural form: small flow gas is suitable for single spray gun structure; Large flow gas suitable for multi nozzle structure;

◆ Flame length, flame cone angle, and flame shape can be designed according to user requirements;

◆ Complete combustion, with combustion efficiency above 99.9%;

◆ The gas nozzle shall not be coking, blocked, backfired, or misfired

XRQ-22 series gas burners are suitable for low pressure and low calorific value combustible gases such as blast furnace gas, converter gas, mixed gas, biogas, etc. They are widely used in various types of boilers, heating furnaces, and other heating devices. Its main feature is that the combustion supporting air is all rotated outward and is mixed with the combustible gas in the central tube while swirling out for combustion inside the burner. This series of burners has good adaptability to low pressure and low calorific value gas, with sufficient combustion, stability, and good regulation, and can achieve low NOx combustion.

Technical features:

◆ Stable combustion, with a combustion efficiency of over 99.5%;

◆ No coking or blockage;

◆ No flashback or misfire;

◆ High energy igniters, flame detectors, ignition propulsion devices, on-site control cabinets, and remote control systems can be configured according to user requirements.

XRQ-23 series acid gas burner is a semi premixed burner developed for special purposes; A combustion device that can burn various types of fuel gas and acid gas. It can burn various fuels alone or mixed. The design of staged combustion and mixed swirling air supply for acid gas and fuel gas can minimize the generation of NOx and meet the dual requirements of process and environmental protection.

Technical features:

◆ Full combustion, no black smoke, less pollution in combustion products, lower than various indicators specified by the National Environmental Protection Bureau;

◆ Complete combustion, with a combustion efficiency of over 99.5%;

◆ High energy igniters, flame detectors, ignition propulsion devices, on-site control cabinets, and remote control systems can be configured according to user requirements.
