Combination of Electrical Heating Elements Containing a Composite Material with Microwave Plasma Torches for High-Temperature Applications in Metallurgy, Chemical Industry and Cement Industry

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a device and method that combines an electric heating element made of advanced composite materials with a microwave plasma torch for high-temperature applications. The combination allows for controlled, gradual heating of surfaces (mainly in industrial reactors or vessels) to prevent cracks and thermal shock, especially important for ceramic or refractory linings. The system is fully electrically powered, can use renewable energy, and avoids the use of combustion gases, making it environmentally friendly and efficient for processes requiring sustained high temperatures, such as in metallurgy, chemical, and cement industries.

Use CasesContent extracted from patent full text and abstract with AI.

• Melting and processing of metals in metallurgy without causing cracks in furnace linings.
• High-temperature sintering or heat treatment of ceramics, refractory bricks, and technical ceramics.
• Manufacturing of glass and specialized glass products requiring slow, controlled heating to avoid damage to linings.
• Sustainable and emission-reducing cement production and processing.
• Thermal treatment and post-processing of composite or carbonous materials in chemical reactors.
• Upgrading or retrofitting existing industrial furnaces to improve lifespan and efficiency of refractory linings.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces the risk of cracking and damage in refractory or ceramic linings during rapid heating.
• Enables more precise temperature control and gradual heating, leading to longer equipment lifespan.
• Fully electric system, allowing operation with renewable electricity and significantly lower CO2 emissions.
• Eliminates the need for hazardous combustible gases, enhancing workplace safety and reducing storage/transport requirements.
• Highly energy-efficient, especially at high temperatures due to the use of a microwave plasma torch with >95% efficiency.
• Easily retrofitted to existing high-temperature industrial setups.
