工业燃烧器

Dunphy’s range of industrial burners is designed to support a variety of applications, from heat and steam systems to process applications and incineration. These solutions work efficiently alongside industrial boilers for complete energy systems. With capacities ranging from 100 kW to 60 MW, our burners are suitable for all types of gas-fired, steam, and incineration boilers, as well as furnaces.

自 1971 年马尔科姆-邓菲(Malcolm Dunphy)为第一台轴向气流燃烧器申请专利以来,我们一直处于节能燃烧技术的前沿。如今,我们的超低氮氧化物燃烧器可提供高效、低排放的解决方案,以满足各种工业应用的需求。

Dunphy burners are equipped with advanced controls for optimal performance, energy efficiency, and emissions reduction, and can be installed within fully prefabricated packaged plant rooms. They are designed to operate on a wide range of fuel types, including: hydrogen, biogas, natural gas, liquid gases, light fuel oils and heavy fuel oils, and can be supported by gas boosters to maintain stable supply and pressure.

什么是工业燃烧器?

工业燃烧器是一种加热装置,用于产生和控制工业流程中的火焰。它以精确的比例混合燃料和空气,以实现高效燃烧。工业燃烧器的应用包括 工业蒸汽锅炉熔炉和烤箱等应用领域。

工业燃烧器系统如何工作?

工业燃烧器系统的工作原理是将燃料和空气按可控比例混合,以产生稳定高效的火焰。鼓风机或压缩机提供空气,燃料阀调节燃料流量。混合物通过火花或引火点燃,为锅炉和熔炉等工业应用产生热量。

What are the advantages of industrial gas burners?

Industrial burners are designed to deliver efficient, reliable and adaptable heat for a wide range of applications. By selecting the right burner, operators benefit from lower costs, greater flexibility and improved environmental performance.

Key advantages include:

  • Industrial burners improve energy efficiency by optimising the air-fuel mix to reduce waste and fuel consumption.
  • Provide precise combustion control that maintains consistent heat and stable operating conditions.
  • Offer fuel flexibility, supporting gas, liquid, dual-fuel and hydrogen-ready applications.
  • They help lower emissions by reducing NOₓ, CO and other pollutants to meet environmental regulations.
  • Reduce maintenance needs as reliable combustion lowers servicing requirements and downtime.
  • Respond quickly to load changes, adapting easily to fluctuations in process demand.

邓菲燃烧器的核心特点

低氮氧化物燃烧

所有 T 系列燃烧器均标配低氮氧化物燃烧头,确保符合排放法规。

高周转率

通过空气雾化,燃烧器在燃气上可实现高达 12:1 的关断,在燃油上可实现 4:1 的关断,在燃油蒸汽上可实现 8:1 的关断,从而确保在不同负荷下的高效运行。

数字调制

数字调制作为标准配置,可确保高精度控制,优化性能并降低油耗。

彻底测试

每台燃烧器在发货前都要在我们的研发测试实验室进行严格测试,以确保最高的可靠性和性能。

英国制造

在英国工厂设计、制造和组装,确保最高质量标准。

低噪音运行

轴向气流设计将电机和风扇封装在铸件内,大大降低了运行噪音水平。

附加功能

虽然 Dunphy 燃烧器通常是为特定应用而定制的,但我们也提供一系列 现成功能可提高性能和排放控制:

氧气调整

调整燃料/空气比例,将过剩氧气保持在最低水平,使燃烧在氧气含量为 2-2.5%的氧气水平。这可以补偿燃料热值、温度和压力的波动。

CO Trim

持续减少空气供应量,使燃烧器能够在低于 1% 的氧气水平下安全运行 氧气含量低于 1从而在最大限度提高效率的同时防止 CO 的形成。

烟气再循环 (FGR)

实现 超低氮氧化物排放低于 30 mg/Nm³100 mg/Nm³因此更符合环保要求。

多喷嘴头

允许双燃料或三燃料配置,使燃烧器能够同时使用多种燃料 同时独立使用.

FAQ’s

What is an industrial burner used for?

Industrial burners provide controlled heat for processes such as steam generation, hot water production, drying, brewing, chemical processing, and waste-to-energy applications.

What fuels can industrial burners operate on?

Most industrial burners are designed for natural gas or oil, but many can operate on dual fuel, biofuels, hydrogen blends or even 100% hydrogen, depending on the specification.

How do industrial burners improve efficiency?

By precisely controlling the air-fuel ratio and flame characteristics, industrial burners maximise usable heat, reduce fuel consumption and minimise emissions.

Do industrial burners require regular maintenance?

Yes, routine inspection and servicing are essential to maintain safe, reliable and efficient operation, though modern burners are designed to minimise downtime.

Can industrial burners help reduce carbon emissions?

Absolutely – low-NOx designs, hydrogen-ready technology and electric options all support decarbonisation and compliance with strict environmental standards.
