Riello Introduces New Range of Monoblock Ultra Low NOx Gas Burners

LEGNAGO, Italy, 2022 年 4 月 5 日，意大利莱格纳戈(LEGNAGO)——为了丰富其产品系 列和满足日益增长的超低氮氧化物(NOx)排放的需求，RIELLO 基于创新的超低氮燃烧头 技术(即 ULX 技术)开发了新型一体式燃烧器系列。 RIELLO 是供暖、空调，节能产品和服 务的领导品牌，是开利全球集团 (纽约证券交易所交易代码为“CARR”)的一部分，开利全 球集团是全球领先的健康、安全以及可持续的智能建筑和冷链解决方案供应商。

LEGNAGO, Italy, 5 th April 2022 – As part of its commitment to expanding its technology portfolio and comply with the increasing demand for very low nitrous oxide (NOx) emissions, RIELLO has developed a new range of monoblock burners based on the innovative ultra low NOx, or ULX, combustion technology. Riello is a leading brand in heating, air conditioning and energy efficiency products and services, and is part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions.

ULX 技术对燃烧过程中产生的各种气流进行控制，从而实现超低氮排放的限制。 采用合适的炉膛尺寸，不需要 FGR 系统，氮氧化物排放可以低于 40 mg/Nm3 @ 3.5% O2; 此外，在特定应用中，也可以实现低于 30 mg/Nm3 @ 3.5% O2 的氮氧化物排放。 RS 68÷510/E ULX 系列燃烧器采用 Riello 公司的新型 ULX 燃烧技术，提供超低氮氧化物 排放，能够满足严格的环保政策。 集成的数字化燃烧器管理系统管理空燃比，以获得卓 越的的输出控制，并确保在比调范围内可以正确的燃烧和安全的运行。

ULX technology operates on the control of the flows that are generated through the combustion process, which are then suitable to achieve low emission limits. With proper combustion chamber dimensions, NOx emissions lower than 40 mg/Nm3 @ 3.5% O2, without any need of FGR system can be obtained; moreover, for specific applications, emissions below 30 mg/Nm3 @ 3.5% O2 are also achievable. The RS 68÷510/E ULX burner series uses Riello’s new ULX combustion technology to provide low NOx emission, capable of meeting stringent environmental regulations. An integrated digital burner management system manages the air-fuel ratio to obtain excellent output control and to assure correct combustion and safe operation on all modulation ranges.

RS/E ULX 系列燃烧器结合了 ULX 技术的燃烧性能和 RS 系列的稳定性和可靠性。一体式的配置将所有组件集成在一个紧凑的尺寸内，便于安装和维护。 ULX 技术带来许 多优势，包括:

The RS/E ULX range combines ULX combustion performance with the consolidated features of robustness and reliability of the RS series. The monoblock configuration allows all the components to integrate in a compact size, to facilitate easy installation and maintenance. The ULX technology brings many advantages, including:

• 安装简便：不需要安装 FGR 系统所需要的回烟管道

• Faster and easier burner installation: does not require the piping system normally needed in the FGR solutions.

• 节约空间：避免锅炉房内部分管道的安装

• Space-saving design: avoids piping in the heating room.

• 烟气内循环：消除管道和机器的冷凝水，延长机器的使用寿命，节约后期维护 成本.

• Internal recirculation: eliminates condensation in both piping and burner, providing long operating life and cost-savings on future maintenance

每一台 RIELLO 燃烧器都是长期的不断设计和制造改进的实践成果。 RIELLO 致力 于投资寻求新的材料和开发更先进的燃烧技术.

Each Riello burner is the result of a long-term experience in design and manufacturing. Riello is committed to investing in the search for new materials and in the development of more advanced combustion technology.
