AI Technical Summary

Technical Problem

Hydrogen boilers emit exhaust gases containing substances that have an impact on the global environment, such as carbon dioxide (CO2) and nitrogen oxides (NOx), which contribute to global warming and pollution.

Method used

A hydrogen boiler system that generates steam by combusting hydrogen and oxygen gases produced from water electrolysis, where the exhaust gases are converted into water vapor, which is then used to preheat feedwater, eliminating the need for a chimney and economizer, and a management device controls the system to optimize steam production and hydrogen storage in response to demand response requests.

Benefits of technology

The system effectively suppresses the emission of harmful gases, reduces manufacturing and operational costs, and contributes to sustainable energy management by optimizing steam production and hydrogen usage in response to demand fluctuations.

Abstract

In a hydrogen boiler (3), hydrogen gas and oxygen gas supplied from a water electrolysis device (2), which generates the hydrogen gas and the oxygen gas by electrolyzing water, are combusted in a combustion chamber of the hydrogen boiler (3), and a water pipe of the hydrogen boiler (3) is heated, thus generating water vapor.
