The purpose of this utility model realizes according to structure described below.This has the multi-chamber coal stove of circulation combustion function, comprise body of heater, flue water jacket and interior flue thereof, water jacket around body of heater is arranged in body of heater, air door is arranged at the bottom corresponding with burner hearth in the front of body of heater, the upper cover plate that has removable circle lid on one its corresponding with each burner hearth that can raise or take off is arranged at the top of body of heater, has secondary air duct in the stove inwall in the body of heater, on body of heater and flue water jacket, water inlet and delivery port are arranged respectively, the air inlet of the inherent air door of burner hearth slightly has one group of fire bars by top, it is characterized in that top at burner hearth, the flame-gathering cover that an arch form is arranged below the upper cover plate, going to the bottom of body of heater is the insulation base plate with one deck heat-insulation layer, and the connection part of per two burner hearths in body of heater is one to have the water jacket partition of water jacket.

The cross section structure of the arch form flame-gathering cover of this multi-chamber coal stove is following one deck cast iron, and the centre is one deck heat-insulation layer, and the outside is the overcoat of layer of metal.

The center line of the flue water jacket of this multi-chamber coal stove and the center line of water jacket partition are substantially in a plane.

The utility model has the advantages that the moulded coal in two burner hearths can circulating combustion or burning separately, relatively simple for structure, last bell can be raised, and the flame-gathering cover of arch also can be raised or be taken off, so that to burner hearth built in type coal, or in burner hearth, take out the moulded coal slag that burnouts.Can cook for family heating, use such as small-sized restaurant.

The following drawings explanation, accompanying drawing 1 is a front view of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the left side view of Fig. 1.Each sequence number in the accompanying drawings is: 1, body of heater, 2, the flue water jacket, 3, air door, 4, moulded coal, 5, secondary air duct, 6, water jacket, 7, flue, 8, the insulation base plate, 9, flame-gathering cover, 10 upper cover plates, 11, the bell circle, 12, water inlet, 13, delivery port, 14, water jacket partition, 15, fire bars, 16,17, hinge.

Below in conjunction with the embodiment in the accompanying drawing, describe structure of the present utility model and use in detail.Shown in accompanying drawing, this has the multi-chamber coal stove of circulation combustion function, comprise a body of heater 1, flue water jacket 2 and interior flue 7 thereof, water jacket 6 around body of heater is arranged in body of heater 1, in the bottom corresponding, the front of body of heater 1 air door 3 is arranged with burner hearth, the upper cover plate 10 that has removable stove circle lid 11 on one its corresponding with each burner hearth that can raise or take off is arranged at the top of body of heater 1, has secondary air duct 5 in the stove inwall in the body of heater 1, water inlet 12 and delivery port 13 are respectively arranged on body of heater 1 and flue water jacket 13, the air inlet of the inherent air door 3 of burner hearth slightly has one group of fire bars 15 by top, it is characterized in that top at burner hearth, the flame-gathering cover 9 that an arch form is arranged below the upper cover plate 10, going to the bottom of body of heater 1 is the insulation base plate 8 with one deck heat-insulation layer, the connection part of per two burner hearths in body of heater 1 is one to have the water jacket partition 14 of water jacket.

Multi-chamber coal stove of the present utility model, the cross section structure of its arch form flame-gathering cover 9 are following one deck cast iron, and the centre is one deck heat-insulation layer, and the outside is the overcoat of layer of metal.Its profile is similar to a stage body of going up circle (day circle) below (place).

Multi-chamber coal stove of the present utility model, the center line of the center line of its flue water jacket 2 and water jacket partition 14 are substantially in a plane.

Be a structure chart in the accompanying drawings with moulded coal stove of two burner hearths.As example, bell circle 11 on the last stove cover plate 10 is taken off, will go up stove cover plate 10 and upwards start, take off the flame-gathering cover 9 of arch along hinge 17, the moulded coal of in burner hearth, packing into, as shown in FIG., 16 moulded coals of can packing into, every heavily about 1 kilogram, put four blocks of coals of igniting at the upper top of moulded coal, after two burner hearths are all filled, flame-gathering cover 9 and upper cover plate 10 are put down, bell circle 11 is covered back original position.Then, the coal of igniting in any burner hearth is wherein lighted, its corresponding air door 3 is opened, and unlit its fire door is closed, and flue gas is discharged from flue 7.The interior moulded coal of unlit that burner hearth this moment, because the air door of this side is closed, therefore, the moulded coal in it can not burn.When the moulded coal in first burner hearth soon during after-flame, with the tegillum in the decorative cover 8 the suitable for reading of arch flame-gathering cover 9 covered, the air door 3 of opposite side is opened, and flame and heat ignite from the moulded coal of the opposite side that the space on water jacket partition 14 tops will not fired, and burn away.Also the moulded coal 4 in two burner hearths can be lighted together, be increased the intensity of heat supply.Generally, 16 moulded coals of a burner hearth can burn 12-14 hour, if bank up a fire, the time can reach more than 24 hours.The moulded coal of two burner hearths is can circulating combustion uninterrupted.When a burner hearth burns separately, except that the position of the decorative cover 11 from last stove cover plate 10 cook boil water, can also be warm at north of china in winter for about 60 square metres room, two burner hearths use simultaneously, can be for 100-140 square metre room heat supply in winter.If special needs are arranged, use this moulded coal stove as brick kitchen range as small-sized restaurant, can adopt the method for (plane) quantity that increases moulded coal, as change into and put 9 or 16 in the plane, (be every thorax 36 or 64) is to increase the intensity of flame, the big fire needs when satisfying the cooking.Can adopt the method that increases monolithic moulded coal weight, increase the intensity of flame, the convenient use.Can also promptly increase by one group or several groups of burner hearths that are communicated with again with the method that increases burner hearth quantity, the centre is separated by water jacket partition 14.In the joint of each group burner hearth, promptly the center of water jacket partition 14 is provided with a flue water jacket 2.When using, at arranged outside one deck thermal insulation layer of body of heater, as the alumina silicate fiber felt or the heat insulating pearlite material of 3-10 cm thick as the brick kitchen range in restaurant.Water-filling or directly water jacket is removed not in the water jacket, and replace with the thermal insulation layer of refractory material.
