Description

Hydrogen heating system for on-site analysis and method of operating the same

The present invention relates to a hydrogen heating system and an operating method thereof, and in particular to a hydrogen heating system and an operating method thereof for on-site analysis.

Achieving carbon neutrality is a goal set by many advanced countries. To achieve this goal, carbon emissions caused by industrial production must be effectively reduced. The steel industry, which has high carbon emissions, is therefore facing great pressure to reduce carbon emissions. Carbon emissions caused by steel production mainly come from the blast furnace ironmaking process, because blast furnace ironmaking uses coke as a medium for iron ore reduction, which will be converted into carbon dioxide and discharged after the reaction. To reduce carbon emissions generated by steel production, the most direct way is to reduce the use of coke.

Methods to reduce the use of coke include adding pre-reduced hot pressed iron or passing hydrogen into the blast furnace. Adding hot pressed iron as part of the iron ore raw material can reduce the use of coke, because the hot pressed iron has a high degree of reduction and does not require coke for reduction. Passing hydrogen can replace part of the coke and serve as a medium for iron ore reduction. These two methods have been the consensus and common methods adopted by many steel mills.

Although both of the above methods can effectively reduce carbon emissions, they will also change the process of blast furnace ironmaking. The blast furnace operating parameters must be redesigned or adjusted to achieve carbon emission reduction while maintaining good blast furnace operating efficiency. The basis for parameter adjustment is the understanding and control of the iron ore reduction mechanism. The first task is to understand the high-temperature reduction reaction in real time and find the important parameters that affect the reaction.

On-site high temperature experiments can detect the progress of high temperature reduction reactions in real time, and are an important tool for exploring the mechanism of iron ore reduction. On-site high temperature experiments for hydrogen reduction of iron ore require a high temperature of 1600 degrees Celsius, a special space design to perform on-site analysis, and the ability to safely control the inflow and outflow of hydrogen. However, when these conditions exist independently, it is a difficult technology, and when combined, there are even greater technical limitations. In addition, hydrogen has a very high thermal conductivity coefficient, which will transfer heat energy to the heating element or cavity and cause thermal melting damage. General high-temperature furnaces are not specially designed for this characteristic to avoid damage. At the same time, there was no special control of hydrogen emissions to achieve safe operating conditions. Hydrogen is a highly dangerous gas and is prone to explosion when the hydrogen concentration is higher than 4%.

Therefore, in order to overcome the shortcomings and deficiencies in the prior art, the present invention is necessary to provide an improved hydrogen heating system for on-site analysis and an operating method thereof to solve the problems existing in the above-mentioned conventional technology.
