Abstract
The utility model discloses an efficient coal furnace; a fire grate is installed at the lower part of a hearth; the upper part of the hearth is provided with a chimney; the front part of the fire grate is provided with a coal feeding hole; the back part of the fire grate is provided with an ash discharging hole; the hearth is internally provided with a heat exchanging tube provided with a water inlet and a water outlet and/or a water tank; the efficient coal furnace is characterized in that an inclined furnace arc higher in front and lower behind is installed at least above the front and/or middle part of the fire grate; the furnace arc is supported by a supporting water pipe inserted through the furnace arc; and the supporting water pipe is communicated with the heat exchanging tube and/or the water tank. The utility model can quicken the speed of igniting the added coals, thereby greatly improving the combustion condition in the furnace so as to burn coal completely and improving the heat efficiency of the coal furnace.
Description
Technical field
The utility model relates to a kind of boiler of briquet.
Background technology
Moulded coal is used for small-sized domestic burners more, when using it for drinking water boiler or driving radiator, want polylith moulded coal placed side by side could satisfy the requirement of high-power burning on the fire grate, usually the coal feed point of this high-power molded coal boiler is arranged on the boiler side walls, when adding new coal from coal feed point, with original moulded coal on the fire grate to pusher, constantly make rear portion the moulded coal of after-flame release from ash hole, and each initiate moulded coal is mainly by lighting at the moulded coal of burning of being adjacent, because briquet is little with the contact area of new adding moulded coal, its flame and hot gas mainly are again to walk to the burner hearth top, so the heat exchanger effectiveness of the two is low, the speed that new coal is lighted is slow, has influenced combustion efficiency, has moulded coal burning problem not to the utmost.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, and a kind of high efficiency molded coal boiler that initiate moulded coal is lighted fast is provided.
For reaching above-mentioned purpose, the utility model adopts following solution: a kind of high efficiency molded coal boiler, be provided with fire grate, top is provided with chimney, the fire grate front portion is provided with coal feed point, and the rear portion is provided with ash hole, is provided with heat exchanging water pipe and/or the water tank of bringing the mouth of a river and delivery port in the burner hearth, it is characterized in that: the low inclination chimney arch in high back before being provided with above fire grate front portion and/or middle part at least, draw back certain distance between the high-end and burner hearth roof of chimney arch.
Above-mentioned high efficiency molded coal boiler is characterized in that: the chimney arch of described fire grate top is supported by the support water pipe that passes it, supports water pipe and is communicated with heat exchanging water pipe and/or water tank.
Above-mentioned high efficiency molded coal boiler is characterized in that: the low inclination chimney arch in high back before multistage more than two is set above fire grate from front to back, leaves exhaust gases passes between the initial and end end of adjacent chimney arch differing heights.
The utility model burns red donor at reliable on the one hand its of the chimney arch that is provided with above the fire grate and lights moulded coal on the fire grate, the low inclination donor in high back can just be guided the rear portion into front portion at the flame and the high-temperature flue gas of briquet on the other hand, accelerates the front portion is newly added the lighting-up rate of moulded coal.The utility model can improve the combustion position of moulded coal in high-power boiler greatly, makes moulded coal be able to abundant burning, improves the thermal efficiency of molded coal boiler.

The specific embodiment
Embodiment 1:
As shown in Figure 1, present embodiment is provided with chain furnace grate 3 in burner hearth 4 bottoms, have coal feed point 11 on the boiler side walls of fire grate front portion, back of furnace row is provided with ash hole 6, upper boiler is provided with the smoke box 7 that is communicated with chimney 9, smoke box is communicated with the burner hearth 4 of bottom by some smoke pipes 8 that pass water tank 10, be provided with heat exchanging water pipe 5 in the burner hearth, be provided with the low inclination chimney arch 1 in preceding high back near anterior fire grate top, chimney arch is supported by the support water pipe 2 that passes it, support water pipe and is communicated with (or be communicated with water tank 10) with heat exchanging water pipe 5, the effect one of support water pipe is the support chimney arch, the 2nd, and make water and high temperature chimney arch in the water pipe carry out heat exchange.The minimum point at chimney arch rear portion is a little more than the height of placing moulded coal on the fire grate, and anterior peak is lower than the burner hearth roof, reserve the propelling passage of moulded coal and level to exhaust gases passes.
Embodiment 2:
As shown in Figure 2, difference from Example 1 is that present embodiment is provided with the low chimney arch 1 in high back before three from front to back above fire grate, leaves exhaust gases passes between the initial and end end of adjacent chimney arch differing heights.
Present embodiment is provided with the multistage chimney arch more than two, and its anterior chimney arch can play the effect of lighting new coal fast, and the rear portion chimney arch is to utilize the high temperature of baking body to make the rear portion fire unburning briquette to obtain further fully burning in the effect of putting in the combusting boiler.In the boiler of new ignition phase, can put into the moulded coal of lighting at every grade of chimney arch rear portion, unlit coal is put in the front portion, lights anterior moulded coal by the moulded coal that chimney arch at different levels are lighted by the rear portion simultaneously, thereby the coal of lighting on the whole fire grate in parallel has improved speed of ignition.
