Ⅰ.Overview of hydrogen heating technology

1.1 Basic characteristics of hydrogen energy

As a clean energy,hydrogen energy has a wide range of application prospects.Hydrogen itself only produces water vapor during combustion and emits almost no harmful gases.Therefore,it is considered to be an ideal choice to replace traditional fossil energy in the future.The application of hydrogen energy is not limited to transportation,power generation and other fields.Industrial heating is another important application direction of hydrogen energy.

The advantages of hydrogen energy include:



Zero carbon emissions:The only product of hydrogen combustion is water,and there is no emission of greenhouse gases such as carbon dioxide during the combustion process.





High calorific value:Hydrogen has a high energy density,and the energy released per unit mass of hydrogen is higher than the same mass of coal or natural gas.





Rich resources:Hydrogen has a wide range of sources and can be obtained through water electrolysis,natural gas reforming and other methods.

1.2 Principle of hydrogen heating technology

Hydrogen heating technology heats industrial materials through the high-temperature heat generated by hydrogen combustion.It is often used in heating furnaces and heating equipment in the production of steel and steel pipes.Compared with traditional coal gas or natural gas heating technology,hydrogen as a fuel has higher thermal efficiency and is more environmentally friendly.

During the steel pipe production process,hydrogen is introduced into the heating furnace as fuel to react with oxygen to generate heat.Through this process,the heating process of the steel pipe becomes cleaner and more efficient.The temperature of hydrogen combustion can be precisely controlled,avoiding material waste and uneven heating problems caused by over-combustion.

Ⅱ.Application of hydrogen heating technology in steel pipe production

2.1 Heating requirements for steel pipe production

Steel pipe production is a complex and delicate process involving multiple links,among which the heating process is the most critical step.During the heat treatment of steel pipes,raw materials(such as steel billets,steel bars,etc.)need to be heated at high temperatures before subsequent cold rolling,cold drawing and other operations can be carried out.This process not only requires the temperature to reach a certain standard,but also requires heating uniformity and temperature control accuracy.

Traditional heating furnaces usually rely on coal gas,natural gas or electricity for heating,but the use of these energy sources is accompanied by a large amount of carbon dioxide emissions and low combustion efficiency.Against this background,the application of hydrogen heating technology has brought new opportunities for steel pipe production.

2.2 Advantages of hydrogen heating technology



Reduced Carbon Emissions:The most significant benefit of steel pipe production is the reduction of carbon emissions.The use of hydrogen as heating fuel not only avoids the use of traditional fossil energy,but also reduces carbon emissions in the steel pipe production process by about 50%,providing important support for the green transformation of the steel industry.





Improve heating efficiency:Hydrogen has a high combustion calorific value and can provide higher temperature heat in a short time.For the heating process in steel pipe production,this can not only shorten the heating time but also improve production efficiency.





Improve product quality:Since the temperature during hydrogen combustion is relatively uniform,more precise temperature control can be achieved,thereby improving the heating quality of the steel pipe and reducing steel pipe defects caused by uneven heating,such as surface cracks and welding defects.





Reduce production costs:With the advancement of hydrogen production technology and the gradual reduction of costs,the cost of hydrogen energy will be further reduced,thereby reducing the total cost of energy consumption in the steel pipe production process.

In traditional steel pipe production,coking furnaces and heating furnaces are the main energy consuming equipment.Traditional heating furnaces use fossil fuels such as natural gas and coal gas.The combustion of these energy sources not only consumes a lot of energy,but also emits a lot of carbon dioxide.By transforming these heating equipment into hydrogen heating furnaces,the carbon emissions of steel pipe production have been effectively controlled.

2.3.2 Efficient heat treatment

The heat treatment process in steel pipe production usually requires heating the steel pipe to hundreds of degrees Celsius to complete grain structure adjustment and hardness control.By using hydrogen heating technology,efficient and uniform heating can be achieved to ensure that the steel pipe products meet standard requirements and improve the strength,hardness and corrosion resistance of the products.

2.3.3 Temperature measurement and energy efficiency optimization

The hydrogen heating furnace is equipped with an advanced temperature control system that can monitor the temperature in the furnace in real time and make precise adjustments according to production needs.This precise temperature control system not only improves the efficiency of the heating process,but also ensures the uniformity of heating and effectively reduces energy waste.
