Abstract (en)

The invention relates to a method for controlling the operation of a boiler (1) having a fuel supply system (2) for supplying fuel gas, in particular hydrogen, from a fuel supply (3) to a fuel gas combusting burner (4), the method comprising determining (S101) whether a risk situation exists based on a security criterion, blocking (S102) the supply of fuel gas in the fuel supply system (2) by means of a first gas valve (5) in case the security criterion is not satisfied, and providing (S103) the burner (4) with fuel gas from the fuel supply (3) by operating at least a second gas valve (6) of the fuel supply system (2) in presence of a heat request, in case the security criterion is satisfied, wherein the security criterion is based on a safety parameter associated with a concentration of fuel gas, in particular of hydrogen, in the fuel supply system (2) and/or on a detected electrical fault in the fuel supply system (2).
