This application relates to a hydrogen-blended combustion system for a coal-fired power boiler and a method for operating the system. The method includes: acquiring the operating status information of the coal-fired power unit; determining the operating stage of the unit based on the operating status information; during a deep peak-shaving period, controlling the pulverized coal-hydrogen mixed burner in the main combustion zone to blend hydrogen for combustion, assisting in stable combustion at low loads; during a period of rapid load increase, controlling both the pulverized coal-hydrogen mixed burner in the main combustion zone and the pure hydrogen burner in the burnout zone to simultaneously blend hydrogen, rapidly increasing the boiler's thermal load; and during a period requiring peak load, controlling both the pulverized coal-hydrogen mixed burner in the main combustion zone and the pure hydrogen burner in the burnout zone to simultaneously blend hydrogen, enhancing the unit's constant load capacity. This effectively improves the dynamic load adaptability of the coal-fired power unit and ensures the combustion effect of the coal-fired power boiler.

The utility model discloses a high efficiency's fierce fire staggered floor combustion system of upper air inlet, include: furnace head subassembly, furnace base, blast box, air blower and fierce fire air outlet structure, blast box and air blower set up in the below of range panel, the blast outlet of fierce fire air outlet structure is located the above of range panel, towards the injection port of injection channel, blast box is equipped with the blast connecting port of connecting fierce fire air outlet structure, and air blower can send air through blast box to the blast outlet of fierce fire air outlet structure, the utility model discloses, break through upper air inlet space limit, realize efficient blast, the core innovation is in the ingenious adoption " blast source lower -positioned, air -supply path up -going, air -out point upper -positioned " split type design. Through special fierce fire air outlet structure, air is accurately delivered to the injection channel injection port near the above of range panel, realizes the core function of forced air supply. This design perfectly adapts the structural characteristics of all upper -positioned of upper air inlet burner injection system.

The application discloses a stove upper air inlet burner, which comprises a burner base and a fire cover, and a circular channel for gas flow is arranged on the surface of the burner base, the circular channel is formed by a left channel and a right channel, the left channel is gradually lifted in the height direction with the change of the central angle and is ended above the right air inlet hole, the right channel is gradually lifted in the height direction with the change of the central angle and is ended above the left air inlet hole, the left and right air inlet holes are respectively extended backward to connect with the injection pipe, a plurality of fire holes are arranged on the outer wall of the circular channel of the burner base, and the fire cover is matched and covered on the surface of the circular channel.
