Abstract

The utility model is solid fuel steam combustion-supporting stove, having a stove body, a hearth and grates for loading fuel and ventilating. Side walls of the solid combustion chamber is made into water jacket form with metals; the upper of the water jacket is welded with a tender filling hole, a metal pipe is communicated at the inner and the outer of the water jacket; the upper end of the metal pipe is higher than the tender filling hole; a micropore is drilled after the lower end opening is plugged up; then the lower end opening of the metal pipe stretches into the center of the grates; a general-purpose safety valve is installed at the bottom edge of the water jacket. The solid fuel steam combustion-supporting stove utilizes the heat of the side walls transmitted by the stove to make the water of the water jacket vaporize to go into the conduit pipe and spray onto the fuel inside the stove to support combustion, and the conserved fuel can reach 80%.

Description

Solid fuel steam combustion-supporting stove

The utility model is a kind of solid fuel cooker, belongs to the F24B technical field.

At present, in samll cities and towns and rural most of family and unit also at the cooking stove that uses coal combustion, bavin, charcoal, the structure of this cooking stove is basic identical, promptly surround burner hearth with metal or fragment of brick, the fire grate of carrying fuel and ventilation is installed at the middle part, it below fire grate grey thorax, the burner hearth medial surface punches and does air feed and ash discharge, fire grate is above to be the combustion chamber, the cooking stove fuel availability of this quasi-tradition is lower, so people have done many improvement to it, but great majority all ventilate with improvement or raising burning back heat utilization ratio is set about, and obtain certain effect.

The purpose of this utility model is: a kind of water vapour of being finished by cooking stove self is provided, produces and spray, and contact with solid fuel, produce the burning cooking stove of combustion-supporting vapour, make be better than existing cooking stove greatly aspect the thermal efficiency of saving solid fuel and raising cooking stove.

Concrete structure of the present utility model is to keep the traditional burner form substantially, only around the sidewall of solid fuel ignition chamber, make water jacket form (water jacket of similar northern heating water warming stove) with metallic plate, the water filling port of belt switch is left on top outside water jacket, make steam lead with one section thin metal pipe in addition, its upper end feeds in the water jacket, and be higher than the water jacket water filling port, fire grate central authorities are stretched in lower end outside water jacket, and the thin metal pipe end opening shut, make a call to a micropore in the respective combustion chamber direction, the fire grate central authorities of corresponding micropore reserve bigger hole, below this external water jacket safety valve is installed, being connected with safety valve is a conduit, and stretches in the water jacket, (safety valve adopts automobile to exceed the water jacket liquid level, the installation valve of tractor air compressor gas storage narrow-necked earthen jar gets final product), more than promptly finish whole technology of the present utility model and constitute.

The course of work of the present utility model is: add water in water jacket, after water is added to the water filling port position, water filling port is closed, the cooking stove coal is lighted, when the water in the water jacket is heated to boiling, just had water vapour to enter steam lead, and by the micropore ejection that is positioned at fire grate central authorities below, directive stove hall contacts with fuel, and chemical reaction takes place, and generates carbon monoxide and oxygen and is used for combustion-supporting.The utility model can be cooked as family according to the purposes difference, and unit heats up water etc. and to make the specification that varies in size.

The utility model good effect is: cooking stove passes the heat to sidewall, the water of water jacket is heated up, vaporization, enter conduit and be ejected into combustion-supporting burning in the burner hearth solid fuel voluntarily, at first can be solid-fuelled 80% to save, this is that other energy-saving cookings are incomparable, in addition, to dryout the back promptly identical with traditional cooking stove state not adding water or water, do not need artificial adjustment conversion, and dry combustion method does not have harm yet.

Fig. 1 is a schematic perspective view of the present utility model.

Wherein: 1 is body of heater, and 2 is grey thorax, and 3 is fire grate, and 4 is the combustion chamber, and 5 is water jacket, and 6 is water filling port, and 7 is steam lead, and 8 is safety valve.

Embodiment of the present utility model is: adopt the roll of steel plate of 0.2 millimeter to be welded into body of heater, the high 200mm of body of heater, diameter 158mm, combustion chamber of furnace body's welding water jacket, water jacket two walls are at a distance of about 1.5cm, weld water filling port in the water jacket outside from upper limb 3 centimeters, water filling port is installed the screw thread sealing cap, safety valve is welded on the water jacket foot to be guided to the safety valve air inlet on the position that is higher than the water surface with a connecting duct, make steam lead inside and outside the fine steel tube perforation water jacket with 0.8 to 10 centimetre of diameter, the steam inlet of steam lead in water jacket is apart from about the water jacket upper limb 5mm, stretch out the outer spray vapour end of water jacket and aim at the fire grate bottom center, apart from fire grate 30-40mm, fumarole is with the weldering of steam lead lower end after death, make a call to the aperture that a diameter is 0.25mm again, fire grate is installed at middle part at body of heater, fire grate can be selected for use in existing form, also can hole with steel plate, but which kind of mode no matter, the circular hole of diameter 30 millimeter all will stay in fire grate central authorities, satisfy the requirement that steam sprays into, more than promptly finished embodiment of the present utility model.

Claims

1, a kind of combustion chamber 4 that comprises, fire grate 3, the solid fuel steam added combustion stove of grey thorax 2, it is characterized in that: sidewall of combustion chamber is made water jacket 5 with metal, water-jacket outer wall has water filling port 6, with the steam lead 7 that water jacket connects, its upper end is higher than water filling port, lower end aligned fire grate 3 bottom center, the water jacket lower edge is welded with steam security valve 8, what be connected with safety valve is a conduit, and stretches into and exceed the water jacket liquid level in the water jacket, wherein leaves the holes that can spray into burner hearth for steam in the middle of the fire grate 3.
