Hydrogen Boiler Modulation Control for Flashback Prevention

The patent applies parameter changes by dynamically adjusting the air-to-fuel mixture ratio (lambda) based on the desired power output. When high power is demanded, the system increases the fuel proportion in the mixture, which increases flame speed and power output. When power demand decreases, the system increases the air proportion, which reduces flame speed and prevents flashback. This continuous parameter adjustment resolves the contradiction between maintaining high power output and preventing flashback.

The patent implements dynamics by making the air-to-fuel ratio adjustable and responsive to changing power demands rather than fixed. The control unit continuously monitors the desired power output and dynamically adjusts the mixture ratio accordingly. This allows the system to achieve high power output when needed (by increasing fuel proportion) while maintaining safety by reducing flame speed through increased air proportion when power demand is low, thus resolving the static contradiction between safety and power output.

The patent applies continuity of useful action by enabling the boiler to operate continuously at varying power levels through modulation of the fuel-air mixture ratio, rather than switching on and off. The control unit adjusts the proportion of fuel and air in the mixture to match the desired power output, allowing the boiler to maintain steady combustion at any level between minimum and maximum capacity. This eliminates the energy losses and equipment wear associated with repeated startup and shutdown cycles while maintaining adaptability to changing heating demands.
