A Low NOx burner is a device designed to reduce the emission of nitrogen oxides (NOx) during combustion. NOx is a major contributor to air pollution, and is mainly produced during the combustion of fossil fuels such as natural gas and diesel.
Low NOx burners are used in a wide range of industries, from power plants and industrial boilers to furnaces and ovens.
Low NOx burners work by reducing the amount of oxygen available during combustion and increasing the temperature of the combustion chamber. This reduces the amount of nitrogen in the fuel, resulting in fewer nitrogen oxides being emitted.
Low NOx burners also employ advanced technologies such as staged combustion and flue gas recirculation to further reduce NOx emissions. These technologies help to increase the efficiency of the fuel combustion process, resulting in less energy being wasted and fewer pollutants being released into the atmosphere.
Low NOx burners are designed to meet strict environmental regulations. They are often required by law in certain areas or industries, as they can drastically reduce the amount of NOx released into the atmosphere.
Low NOx burners are also energy efficient, as they help to reduce energy waste. As a result, they can help to reduce energy costs for businesses and households.
The Global Low NOx Burner Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A NEW line of ultra-low NOx emission burners was introduced by Riello. In order to assure compliance with various environmental and regulatory standards, legislation is continuously lowering the allowable NOx emission limits from combustion equipment.
Additionally, appliance emissions are being monitored more frequently. The use of premix burner technology or flue gas recirculation (FGR) technology have historically been the two main methods used to reduce combustion NOx emission levels.
While the effectiveness of each of these solutions in lowering appliance NOx emission levels is acknowledged, their applications are limited in certain ways.Additional ducting from the appliance flue to the burner and a higher level of burner technology are needed for FGR technology.
This has various restrictions on operation regarding the lowest allowed recirculating flue gas temperature and increases installation complexity and maintenance expenses.The highest capacity limit of premix technology is comparatively modest, at about 3,000 kW.
Additionally, the installation and maintenance expenses are increased due to the configuration of the long combustion head that is needed.These application limitations that hinder the use of FGR and premix technologies are removed by the NEW Riello ULX Series of Ultra-Low NOx emission gas burners, which offers a solution that can be used on all boiler types and at all operating temperatures.
The reliability and resilience of previous models are maintained by the NEW series burners, which are fundamentally based on the tried-and-true Riello RS pressure jet burner design principles.
Although the Riello ULX series’ unique and proprietary combustion head technology “breaks new ground” in terms of reducing NOx emissions, at first glance they appear to be quite similar to burner types that have been on the market for a long time.
The combustion head design of the burners in the Riello ULX series integrates two controls: “internal flue gas recirculation” in the outer area of the flame and “staged air” introduction control in the “core” of the flame.
Due to the combustion head technology’s subsequent decrease in NOx emissions, a variety of appliance types, including steam and high-temperature hot water boilers, may comply with the strictest regulations in the globe.
