What is a radiant tube and how does it work?
Radiant tubes are a key component in various heating systems, playing a vital role in providing efficient heat transfer. Whether you’re exploring metal treatment or furnace industry, understanding what radiant tubes are and how they work can greatly enhance your knowledge of heating systems. In this blog post, we will delve into the exploring the purpose of radiant tube heater, features, and operation. We will also explore why we stand out as a leader in manufacturing the finest radiant tubes in India.
What is a radiant tube heater?
Radiant tubes are tubular heating elements designed to emit radiant heat. They are typically made of durable material such as stainless steel, ensuring high-temperature resistance as well as longevity. Used in extremely demanding environments, radiant tubes are leak-proof and corrosion-resistant, among other unique features. Radiant tubes are primarily used in heating systems, where their ability to transfer heat through radiation plays a crucial role.
Radiant tubes are seamless tubes that are made up of heat-resistant materials like iron-chromium-aluminium alloys, nickel-based alloys, etc. Stainless steel tubes are commonly used due to their excellent heat resistance and durability. Operating temperatures of up to 1100 °C are supported by these alloys. Radiant tubes can function independently or in conjunction with bundle rod heaters. When used with bundle rod heaters, they can be used for temperatures up to 1400 °C and have superior performance.
It prevents the heater from coming into direct contact with the furnace’s atmosphere. A radiant tube must have good mechanical properties at high temperatures. When power is supplied to the heater, heat is generated because of the joule’s heating. This heat is transferred from the electric heater to the radiant tube by radiation. And then on, from the radiant tube to the material being heated. The material gets heated up by irradiation from the radiant tube.
Highly customized to meet specifications, they are mostly used for electrically heated furnaces. They are employed in industrial furnaces, ovens, and kilns to provide precise and controlled heating for processes such as metal heat treatment, glass manufacturing, and food processing.
Moreover, radiant tubes find extensive use in various furnaces, including, melting, dosing and holding furnaces, laboratory furnaces, etc.
What are the features of a radiant tube heater?
Radiant tube heaters offer several features that make them a popular choice for heating applications. Here are some key features of radiant tube heaters:
- Efficient Heat Distribution: Radiant tube heaters are designed to provide even as well as targeted heat distribution. The radiant heat emitted from the tubes travels in straight lines, directly heating objects and surfaces in its path without the need for air circulation.
- Energy Efficiency: By directly heating objects and surfaces, they eliminate the need to heat and circulate large volumes of air, reducing energy consumption compared to traditional heating systems.
- Rapid Heat Response: These heaters heat up quickly and provide rapid heat response. This feature is particularly beneficial in applications where immediate heat is required, such as industrial processes or commercial spaces.
- Zoning Capabilities: Radiant tube heaters often have zoning capabilities, allowing users to divide an area into different zones and control the heat output for each zone independently.
- Durability and Longevity: Radiant tube heaters are built to be durable and long-lasting. The tubes are typically constructed from materials such as stainless steel or ceramic, ensuring resistance to corrosion as well as high-temperature environments. Due to the capability of forming a dense and adhesive oxide film and the excellent mechanical properties of radiant tubes, which increase the operating life,
- Versatile Installation Options: They can be mounted overhead, suspended from ceilings or walls, or installed horizontally or vertically, depending on the space and heating requirements.
- Superior power rating: Ferritic alloys provide a higher power rating than any other metallic heating system.
Overall, radiant tube heaters combine energy efficiency, rapid heat response, and even heat distribution to provide effective and reliable heating solutions for a variety of settings, including industrial applications.
