More Information
Summary:The utility model belongs to the technical field of energy conservation of coal-fired boilers, and discloses an adjacent boiler hot air energy-saving device for pulverized coal boilers, which is characterized in that primary main air pipes of a plurality of pulverized coal boilers are sequentially communicated through a connecting air duct, sealing valves are arranged at two ends of the connectingair duct between two adjacent pulverized coal boilers, and an air volume regulating valve is arranged between the two sealing valves; according to the utility model, the primary main air pipes of a plurality of pulverized coal boilers are communicated with one another by using the connecting air duct, and when the pulverized coal boilers are started from a cold state, the connecting air duct canbe used for conveying hot air of adjacent boilers to provide energy required for starting the boilers; when the boilers operate at a low load, hot air of the adjacent boilers can still be conveyed through the connecting air du
