Abstract

The utility model discloses a high efficiency coal-saving multipurpose stove, which is composed of a stove body housing (1) and a stove liner (2). The utility model is characterized in that the inner wall of the stove liner (2) is a water jacket (3), and the top of the stove liner is an annular water jacket (11). The upper side of the annular water jacket (11) is provided with a fire banking cover (14), and the lower side is provided with a planar or an angle-shaped water jacket (12) communicated with the inner wall water jacket (3). The planar middle part of the water jacket (12) is provided with a circular hole (13) which is provided with a fire rising barrel (15); the interior of the stove liner (2) is divided into a coal-fired chamber (19) and a gas-fired chamber (16) by arrangement of double-layer water jacket, and thus, the utility model has little heat energy loss and large water capacity. The utility model is provided with the fire rising barrel (15), and thus, the fire intensity during cooking can be improved. The utility model has the advantages of fuel saving, high thermal efficiency and convenient and quick cooking function.

Description

The high-efficient coal-saving multipurpose furnace

The utility model relates to the stove that heating for residential area is used, and particularly a kind of centralized procurement is warm, cooking and bathing be in the high-efficient coal-saving multipurpose furnace of one.

At present, the coal-saving stove of market supply is various in style, each tool uniqueness of function, but ubiquity heat energy is serious from the chimney loss, the thermal efficiency is low, the drawback of cooking firepower deficiency.

The purpose of this utility model provides the high-efficient coal-saving multipurpose furnace that a kind of coal consumption is low, the thermal efficiency is high, the cooking firepower is strong.

The concrete technical scheme that realizes the utility model purpose is: stove is made up of body of heater shell and flue, characteristics are that inboard wall of furnace is a water jacket, its top is a ring-shaped water jacket, have above the ring-shaped water jacket fire sealing cover, below be a plane that is communicated with the inwall water jacket or dihedral water jacket, on the plane or the in-plane of dihedral water jacket have hole, a garden, on the hole, garden, be equipped with a fire poking barrel; Be provided with heat-insulation layer between body of heater shell and the flue.

The utility model is because flue has adopted the double-layer water jacket segmenting structure, and water capacity is big, and the hot-fluid stroke extends, and directly radiation has made full use of coal-fired heat energy on the water jacket surface.Open garden shape poke hole in the middle of plane or the dihedral water jacket, can lay fire poking barrel, the firepower when greatly having improved cooking, convenient and swift.

Among the figure: the coal-fired chamber of the 1-body of heater shell 2-flue 3-inwall water jacket 4-hot water outlet pipe 5-return pipe 6-chimney 7-fire grate 8-ash bucket 9-crank 10-air door 11-ring-shaped water jacket 12-dihedral water jacket 13-garden hole 14-fire sealing cover 15-fire poking barrel 16-17-of fuel chamber heat-insulation layer 18-venting 19-

Below in conjunction with accompanying drawing the utility model is described in detail:

Consult accompanying drawing 1, flue 2 inwalls are a water jacket 3, the top is a ring-shaped water jacket 11, there is fire sealing cover 14 ring-shaped water jacket 11 tops, there is a plane that is communicated with inwall water jacket 3 or a dihedral water jacket 12 below, have hole, a garden 13 at the middle part on water jacket 12 planes, on hole, garden 13, be equipped with a fire poking barrel 15, by ring-shaped water jacket 11 and plane or dihedral water jacket 12 are set, make and be divided into coal-fired chamber 19 and fuel chamber 16 in the flue, do not have clean-burning coal gas in coal-fired chamber 19 and mix the back in fuel chamber's 16 internal combustion from the air that coal filling hole enters, direct heating water jacket 11, when in the stove during coal combustion, the water in the inwall water jacket 3 is heated nature and rises and enter extraneous caliduct from outlet pipe 4, sends into heat exchanger, cold water nature under the thrust of hot water enters in the inwall water jacket 3 from water return outlet 5, to reach Natural Circulation heating purpose.Under the cooking state, when needing strong firepower, take off fire sealing cover 14, fire poking barrel 15 is placed on the hole, in-plane garden 13 of plane or dihedral water jacket 12, the height intensity of flame can improve greatly like this.

Be provided with heat-insulation layer 17 between the utility model body of heater shell 1 and the flue 2.
