The utility model content
The purpose of this utility model is utilized the existing waste heat boiler equipment of power plant, transform a kind of petroleum coke powder combustion power generation device that substitutes right steam turbine exhaust heat that the burning petroleum coke powder replaces the steam turbine waste heat to generate electricity as.
The utility model is achieved in that a kind of petroleum coke powder combustion power generation device that substitutes right steam turbine exhaust heat, burner hearth interface at waste heat boiler connects petroleum coke powder auxiliary combustion mechanism, described petroleum coke powder auxiliary combustion mechanism comprises whirlwind tube combustion chamber and secondary furnace, secondary furnace one side is connected with whirlwind tube combustion chamber and communicates, the opposite side of secondary furnace is connected with the burner hearth interface of waste heat boiler, described secondary furnace is provided with a minimum air inlet, the air inlet is connected with air injection tube, purpose from air to secondary furnace that inject is the temperature that reduces wherein, and it is overheated and damage burner hearth to avoid injecting air in the waste heat boiler burner hearth.
The top of described whirlwind tube combustion chamber is provided with burning spray gun, sidewall above the whirlwind tube combustion chamber is provided with tangent air inlet, the inwall place of the corresponding secondary furnace port in whirlwind tube combustion chamber is provided with downward-sloping flue gas guide plate, guide plate makes whirlwind tube combustion chamber and secondary furnace form exhaust gases passes, and the bottom of whirlwind tube combustion chamber is provided with the sediment outlet.
Described tangent air inlet comprises tangent air inlet and secondary tangent air inlet, and tangent air inlet and secondary tangent air inlet are to arrange successively from top to bottom in the both sides of combustion chamber wall surface.
It is conical that the bottom of described combustion chamber is, and the below of sediment outlet is provided with detritus tank.
The downward-sloping angle of described flue gas guide plate is 60 °.
The utlity model has following advantage: under the situation that does not change existing electric power factory equipment, on waste heat boiler, increase petroleum coke powder auxiliary combustion mechanism and just can make waste heat boiler running generating, in transformation process, need not to change the original structure of boiler, can realize that petroleum coke powder replaces fuel oil, natural gas and kerosene to act as a fuel, and has saved fuel cost greatly, and discharge low, do not have any transformation risk, keep original combustion apparatus, provide multiple choices to the user.
