The world's first! Nikko has developed the world's first hydrogen burner dedicated to asphalt mixing equipment, which achieves zero carbon dioxide emissions during aggregate drying and heating

April 28, 2023

Foreword：Nowadays，All countries in the world want to achieve it as soon as possible“The carbon reaches the peak·Carbon neutral”Work hard for the strategic goal.。Hydrogen energy has the characteristic of not producing carbon dioxide when it is burned.，It has become the most potential new energy in the 21st century.。Japan is one of the largest carbon dioxide emitters in the world.，Continuous efforts have been made in energy conservation and emission reduction.，Except in the use of hydrogen technology in running cars.，The use of hydrogen energy is also expanding in other areas.。

This time，Nikko Group and Tokyo Gas Company have jointly developed the world's first hydrogen Burner for asphalt mixing equipment.。The Burner is suitable for the drying and heating of aggregate。Technically realize 100%Hydrogen combustion，Or mixed with natural gas for combustion。After the final certification by the relevant department，It is planned to start actual sales and use in Japan in March 2024。

The world's first hydrogen Burner

Asphalt Mixing Plants in Japan emit about 1.3 million tons of carbon dioxide every year.，About 80 of them%It is produced by the burning of fuel during the drying and heating of the aggregate.。So，Use hydrogen that does not produce carbon dioxide when burned，In the future, it will be one of the powerful choices for asphalt mixing equipment to achieve the goal of low carbon emissions.。On the other hand，When hydrogen is used as fuel，Its characteristics are different from natural gas.，In addition to producing water during combustion,，At the same time, a certain amount of nitrogen oxides will be produced.。

And this time，Nikko Group and Tokyo Gas Co.，Through the redesign of the atomization structure of the existing burner of Nikko，Realize the combustion technology of low emission of nitrogen oxides。In a related experiment，Tested，The hydrogen burner achieves lower carbonitride emissions than conventional natural gas burners。

Nikko and Tokyo Gas plan to start with 500 in March 2024.KWA small burner is introduced to the market.，After that, the product scale was expanded one after another.。The newly developed hydrogen energy low-carbon burner technology has also been promoted in furnaces and other industries.，Further for human beings“The carbon reaches the peak·Carbon neutral”Make a contribution to the cause。

Relevant use of Asphalt Mixing Plant

April 2023，Nikko Group cooperates with Maeda Road Company, one of the largest road construction enterprises in Japan.，Asphalt mixture produced using the world's first hydrogen burner，And the related paving experiments were carried out.。In the experiment，The physical property and construction performance of the mixture are strictly analyzed and studied.，It was a complete success.。
