Burner boilers are the functional components of boilers that provide heat input by burning a fossil fuel, including natural gas, with air or oxygen. They are available as part of the boiler package from the manufacturer, as stand-alone products for special installations or as replacement products.

Natural gas fired boiler burners can achieve very low emissions. Reducing nitrogen oxide (NOx) emissions has been the focus of natural gas boiler burners, and some models can achieve NOx below 10 ppm.

Boiler burners are often adjustable for different fuel compositions or may also include dual fuel ignition features.

High Speed ​​Boiler Burners

High rpm burners can be much more efficient. Burners that are not high-speed may turn on and off constantly, respond slowly to load changes, or have trouble maintaining proper steam pressure and water temperature. Without high tilting, the burners can waste a lot of energy. Enthalpy high tilt burners solve all these problems and more.

          High speed burners provide up to 12:1 tilting to meet boiler load requirements and reduce on and off cycles. Burners not designed to do so will constantly switch on and off, resulting in “cleaning or cycle losses”. When it cools, the evacuation air passes through the boiler, removing the heat and venting it out the chimney, which wastes energy and increases fuel costs. Frequent on and off cycles also increase maintenance costs due to excessive component wear. Benefits of high tilt burners include:

• Increased energy efficiency by reducing disposal losses
• Better responsiveness to boiler load changes
• Improved control and stability of vapor pressure or water temperature
• Lower maintenance costs and increased reliability due to less component wear and failure from excessive starting and stopping
• Reduced thermal shock for boiler and refractory

Gas Burners

In general, it is possible to divide gas-fired burners into two as atmospheric and blown burners. Atmospheric burners have great advantages in building heating applications. However, premixed blown burners developed for this type of boilers in recent years have significant advantages, especially in terms of environmental emissions. This type of burner is used in many fairly new appliances, especially wall-mounted appliances. When a pre-mixed burner is used in condensing wall-mounted boilers, the heating power can be up to 65 kW. The specific power of the combustion pipes used here is around 8001400 kW/m2. In this type of burners, the gas fuel is mixed with the combustion air at the rate required for complete combustion. The combustible mixture thus obtained is sent to the combustion chamber. Here, the air share in the mixture remains the same under all combustion conditions. Therefore, the flue gas composition as a result of combustion will not change. The supply of combustion air, its mixing with gaseous fuel and its regulation are provided by a fan support. The combustion chamber is completely closed. The circulation and discharge of the flue gases are provided by the chimney and the person or the fan. The stability and safety of the flame depends on the perfection of the mixture. Premix combustion systems are somewhat similar to atmospheric burners.
