When use, in the burner hearth with wind formula air inducing vertical coal-burning hot-air furnace, add fuel from fire door, start air blast, allow wind upwards discharge at a high speed from the exhaust outlet in smoke exhaust pipe, with the air in flake hearth-tapping, make generation negative pressure in burner hearth, allow air enter burner hearth from primary air nozzle, be conducive to the fired coal combustion in burner hearth, fuel burns above fire grate, the hot heating furnace wall chuck and the heat-exchanger rig that produce, allow the heat-exchanger rig of normal temperature air in air inlet enters chuck and burner hearth and discharge from air outlet, make to be heated to form hot blast through the normal temperature air of cover and heat-exchanger rig, hot blast is discharged and is used from air outlet.
In prior art, the smoke exhaust pipe of body of heater top is only connected with an air blast, and when use, an air blast is with constant air inducing ability air inducing.In actual moving process, change with the combustion case of wind formula air inducing vertical coal-burning hot-air furnace burner hearth, the combustion case of burner hearth is good sometimes, and the combustion case of burner hearth is bad sometimes, and the good of the combustion case of burner hearth is different from the bad requirement to a wind.When the combustion case of burner hearth changes, use all the time a kind of constant air inducing ability air inducing, the power consumption of air blast is higher, is also unfavorable for the burning of burner hearth.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, when the combustion case that proposes a kind of burner hearth changes, and the two-shipper dual control band wind formula air inducing vertical coal-burning hot-air furnace that air inducing ability also changes.
The utility model is realized with the following method.
Two-shipper dual control band wind formula air inducing vertical coal-burning hot-air furnace has vertical furnace, there is chuck in body of heater outside, furnace body outer wall in chuck has fin, air inlet is arranged at the bottom of chuck, air outlet is arranged at the top of chuck, fire grate is arranged at the bottom in body of heater, on the body of heater of fire grate top, there is fire door, air port once on the body of heater of fire grate below, there is heat-exchanger rig burner hearth top in body of heater, there is exhaust opening the upper end of body of heater, exhaust opening is connected with smoke exhaust pipe, there is the first blast orifice the side of smoke exhaust pipe, sidewall in smoke exhaust pipe has the first parallel exhaust outlet upwards of the axis of the axis connected with the first blast orifice and smoke exhaust pipe, there is the first air blast body of heater top, the outlet of the first air blast is connected with the first blast orifice of smoke exhaust pipe side, there is the second blast orifice the pipe side on the first opposite, blast orifice top of smoke exhaust pipe, sidewall in smoke exhaust pipe has the second parallel exhaust outlet upwards of the axis of the axis connected with the second blast orifice and smoke exhaust pipe, there is the second air blast the side of smoke exhaust pipe, the outlet of the second air blast is connected with the second blast orifice, the outlet of the second air blast is hinged with valve plate.
When use, allow the heat-exchanger rig of normal temperature air in air inlet enters chuck and burner hearth and discharge from air outlet, in the burner hearth with wind formula air inducing vertical coal-burning hot-air furnace, add fuel from fire door, start the first air blast and the second air blast, allow wind upwards discharge at a high speed from the exhaust outlet in smoke exhaust pipe, with the air in flake hearth-tapping, make generation negative pressure in burner hearth, allow air enter burner hearth from primary air nozzle, be conducive to the fired coal combustion in burner hearth, fuel burns above fire grate, the hot heating furnace wall chuck and the heat-exchanger rig that produce, make to be heated to form hot blast through the normal temperature air of cover and heat-exchanger rig, hot blast is discharged and is used from air outlet.
The utility model has the first air blast and two air blasts of the second air blast for being with wind air inducing, in the time that the fired coal combustion situation in burner hearth needs larger ventilation, the first air blast and the second air blast can be opened simultaneously, in the time that the fired coal combustion situation in burner hearth does not need larger ventilation, can close the second air blast, only use the first air blast, now, the hinged valve plate of the second blower export is closed, the air inducing interaction energy that prevents the first air blast is introduced air from the second blower export through the second air blast, affect the air inducing effect of the first air blast to burner hearth.Because valve plate is the outlet that is hinged on the second air blast, the weight of valve plate need to be designed in the time of the first air blast air inducing, the air inducing active force of the first air blast can not be opened the second hinged blower export valve plate, and in the time of the second air blast air inducing, the blasting action power of the second air blast can be opened the second hinged blower export valve plate.
