Boiler with a heat generation body that stores hydrogen

A method of controlling a boiler, comprising the steps of:

• a. before safely operating a normal operation of the boiler, supplying a predetermined purge gas into a circulation path until a first predetermined condition is reached;
• b. after reaching the first predetermined condition of the purge gas in the circulation path, supplying a predetermined hydrogen-based gas during a charge process into the circulation path while discharging the purge gas using a vacuum pump during a discharge process at the same time;
• c. during the step b, monitoring in the circulation path a predetermined combination of a circulation amount and a concentration of a mixture of the hydrogen-based gas and the purge gas during the charge process and the discharge process to provide monitored values;
• and
• d. upon reaching a second predetermined condition based upon the monitored values, stopping the charge process and the discharge process while starting to heat the boiler for the normal operation of the boiler.

• a. before safely operating a normal operation of the boiler, supplying a predetermined purge gas into a circulation path until a first predetermined condition is reached;
• b. after reaching the first predetermined condition of the purge gas in the circulation path, start heating the boiler to a predetermined safe temperature and supplying a predetermined hydrogen-based gas during a charge process into the circulation path while discharging the purge gas using a vacuum pump during a discharge process at the same time;
• c. during the step b, monitoring in the circulation path a predetermined combination of a circulation amount and a concentration of a mixture of the hydrogen-based gas and the purge gas during the charge process and the discharge process to provide monitored values;
• and
• d. upon reaching a second predetermined condition based upon the monitored values, stopping the charge process and the discharge process while starting to heat the boiler beyond the predetermined safe temperature for the normal operation of the boiler.
