Abstract
A hot-blast stove with secondary air inlet is provided with a vertical stove body cylinder which is provided with a clamping sleeve outside, wherein the lower portion in the stove body is provided with a stove grate, a stove door is arranged on the stove grate, an ash outlet is arranged under the stove grate, the upper end of the stove body is provided with a smoke discharge port, a ring-shaped baffle plate for separating a cylindrical clamping sleeve into an upper air chamber and a lower air chamber is arranged in the cylindrical clamping sleeve, the lower portion of the lower air chamber is connected with an air inlet, the lower portion of the upper air chamber is provided with an air outlet, air pipes which are in parallel with an axial cord of the stove body are evenly distributed in the stove body cylinder, the upper ends of the air pipes are connected with the upper portion of the upper air chamber, the lower ends of the air pipes are connected with the upper portion of the lower air chamber, and one to twelve secondary air inlets which are communicated with the lower air chamber and are evenly distributed along the circumference are arranged in the stove body and the stove body cylinder wall above the stove grate. The hot-blast stove with secondary air inlet not only has primary air for assisting combustion, but also enables air to enter a hearth through the secondary air inlets from the lower air chamber, secondary air which enters the hearth provides fuel in the hearth with the secondary air for assisting combustion, which is beneficial for the combustion of the fuel in the hearth, the fuel can be combusted more fully, and the heat efficiency of a hot-blast stove can be higher.
Description
Technical field
The utility model relates to the secondary wind inlet of a kind of hot-blast stove, particularly a kind of hot-blast stove.
Background technology
Hot-blast stove has the vertical and cylindrical body of heater, the body of heater cylinder has the cylindrical shape chuck outward, fire grate is arranged at the bottom in the body of heater, on the body of heater of fire grate top fire door is arranged, on the body of heater of fire grate below ash hole is arranged, there is exhaust opening the upper end of body of heater, there is the annular dividing plate that the cylindrical shape chuck is divided into upper and lower two air compartments in the cylindrical shape chuck, air intake vent is arranged at the bottom of lower air chamber, air outlet is arranged at the bottom of ipper air chamber, be evenly equipped with the airduct parallel with the body of heater axis in the stove cylinder, the upper end of airduct links to each other with the top of ipper air chamber, and the lower end of airduct links to each other with the top of lower air chamber.Fire grate top in the body of heater is the burner hearth of fuel combustion, during use, adds fuel from the fire grate of fire door in burner hearth, the burner hearth internal combustion of fuel above fire grate, during fuel combustion, a wind enters through fire grate from ash hole and enters burner hearth, for the fuel combustion in the burner hearth combustion-supporting.In the prior art, above-mentioned hot-blast stove is the wind inlet for once, does not have the secondary wind inlet, and during use, the fuel combustion in the burner hearth is not very abundant, and the thermal efficiency of hot-blast stove is not very high.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and the fuel combustion that proposes in a kind of burner hearth must be more abundant, the hot-blast stove with secondary wind inlet that the thermal efficiency of hot-blast stove is higher.
The utility model is realized with the following method.
Hot-blast stove with secondary wind inlet has the vertical and cylindrical body of heater, the body of heater cylinder has the cylindrical shape chuck outward, fire grate is arranged at the bottom in the body of heater, on the body of heater of fire grate top fire door is arranged, on the body of heater of fire grate below ash hole is arranged, there is exhaust opening the upper end of body of heater, handlebar cylindrical shape chuck is divided in the cylindrical shape chuck, the annular dividing plate of following two air compartments, air intake vent is arranged at the bottom of lower air chamber, air outlet is arranged at the bottom of ipper air chamber, be evenly equipped with the airduct parallel in the body of heater cylinder with the body of heater axis, the upper end of airduct links to each other with the top of ipper air chamber, the lower end of airduct links to each other with the top of lower air chamber, in body of heater, the body of heater cylindrical wall of fire grate top has with lower air chamber and communicates, 1～12 the secondary wind inlet that is uniformly distributed along the circumference.
During use, send into air with blower fan from the downward air compartment of air intake vent, air is discharged from air outlet after lower air chamber, airduct and ipper air chamber, in burner hearth, add fuel from fire door, fuel burns above fire grate, the heat that produces adds warm-air pipe and chuck, makes the normal temperature air through lower air chamber, airduct and ipper air chamber be heated to form hot blast, and hot blast is discharged from air outlet and used.When fuel burns on the fire grate of hot-blast stove, except that one time wind is combustion-supporting, air can enter in the burner hearth by the secondary wind inlet from lower air chamber, the secondary wind that enters in the burner hearth provides combustion-supporting secondary wind for the fuel in the burner hearth, help the burning of fuel in the burner hearth, allow the fuel combustion must be more abundant, make the thermal efficiency of hot-blast stove higher.
On the body of heater cylinder outer wall face in the utility model chuck fin is arranged, make the heat transfer area of hot-blast stove bigger, the thermal efficiency of hot-blast stove is higher.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is a kind of main cross-sectional schematic with hot-blast stove of secondary wind inlet that proposes according to invention scheme of the present utility model.
