Abstract

The utility model discloses a novel vertical boiler, wherein, a furnace fire bar (2) of the boiler is a half-open type, that is, the half furnace fire bar close to one side of a fuel feeding port (7) is opened, while the other half furnace fire bar is closed, the closed furnace fire bar is provided with an ash discharging port (4) of a slag chamber (6), an arc closed grate (1) is arranged inside a lower hearth (3), the grate (1) is connected with a boiler inner wall (8) and the opened furnace fire bar (2) to form a combustion area (9), a smoke outlet (5) of a smoke through chamber is positioned on the arc grate (1). The utility model is of simple structure, low cost, fuel coal saving and high heat efficiency of the boiler.

Description

The novel vertical boiler

Affiliated technical field

The utility model relates to manual stove, is specifically related to a kind of structure of novel vertical boiler.

Background technology

Present manual boiler, between its stove hall and the smoke-box is open communication, the lower hearth that burns within it for coal in the fire bars top, the burning of fixed carbon, except that the condition that wind will be arranged, a hot conditions also will be arranged, and when temperature surpassed 1200 ℃, burning velocity sharply rose, therefore to make the abundant after-flame of fuel, the high temperature of keeping the fixed carbon combustion zone is extremely important, and for existing manual boiler, the CO that the bottom burning generates ₂Can be reduced upwards through the red-hot carbon in upper strata the time and generate CO, this is an endothermic reaction, thereby causes the relative cooling of this section superjacent, make the burning of fixed carbon be tending towards difficulty, it is weak gradually to be more common in flame weak point and burning, and waste is coal-fired, and boiler thermal output is low.

Summary of the invention

The purpose of this utility model is: design a kind of novel vertical boiler, improve structure on the basis of vertical manual stove, reach and be sparing in the use of coal, alleviate kettleman's labour intensity, improve the purpose of the thermal efficiency.

Technical solution of the present utility model is: the fire bars of this boiler is a semi open model, promptly the half of fire bars near the fuel charge oral-lateral is open, and second half is closed, on the fire bars of sealing, open the ash hole of cinder chamber, in following stove hall, establish a fire grate that is the sealing of arch, this fire grate and boiler inner wall and open fire bars are connected to form the combustion zone, and the exhanst gas outlet of logical smoke-box is positioned on the arch fire grate.

Description of drawings

Fig. 1 is the utility model structural representation

Among the figure: 1 arch fire grate, 2 fire bars, 3 times stove halls, 4 ash holes, 5 exhanst gas outlets, 6 cinder chamber, 7 charge doors, 8 boiler inner walls, 9 combustion zones

The specific embodiment

As shown in Figure 1, the fire bars 2 of this boiler is a semi open model, promptly the half of fire bars near fuel charge mouth 7 sides is open, and second half is closed, on the fire bars of sealing, open the ash hole 4 of cinder chamber 6, the fire grate 1 that is the sealing of arch is set in the stove hall 3, and this fire grate 1 connects boiler inner wall 8 and open fire bars 2 forms combustion zone 9, and the exhanst gas outlet 5 of logical smoke-box is positioned on the arch fire grate 1.

The utility model is because of being provided with the arch fire grate, sealed partly fire bars, stove hall volume has been dwindled, formed stable high temperature combustion zone, strengthened the air-flow of combustion zone, prolonged the stroke of flue gas, coal can obtain fast burning fully, CO, OH that high-temperature flue gas, air (excess oxygen) and combustion zone produce ₄, CO ₂Deng fully mixing and burning away, thermal loss has reduced, and the thermal efficiency of boiler is improved.

Claims

1, novel vertical boiler, it is characterized in that: the fire bars of this boiler (2) is semi open model, promptly the half of fire bars near fuel charge mouth (7) side is open, and second half is closed, on the fire bars of sealing, open the ash hole (4) of cinder chamber (6), the fire grate (1) that is the sealing of arch is set in the stove hall (3), and this fire grate (1) connects boiler inner wall (8) and open fire bars (2) forms combustion zone (9), and the exhanst gas outlet (5) of logical smoke-box is positioned on the arch fire grate (1).
