At present, the cooking heating furnace that use the rural area mainly is main fuel with bituminous coal and anthracite etc., this cooking heating furnace mainly is made up of parts such as body of heater, water jacket, fire grate, burner hearth, chimneys, mainly, adopt combustion system from bottom to top, adopt this combustion system from the fire grate oxygen supply, the fuel that adds and the coal ash of generation will stop up the oxygen supply passage, fuel combustion is insufficient, makes some fuel gas directly arrange to atmosphere, has not only wasted the energy but also polluted environment.Find that by on-site inspection existing cooking and heating furnace mainly is to have following defective: 1, fuel combustion is insufficient.Produce tar when 2, burning.3, fire-sealing time is short.4, expend the energy.5, the chimney utilization rate of waste heat is low.6, indoor temperature rises slow.
Summary of the invention:
Purpose of the present invention is exactly to change the existing rural area defective that the used cooking stove of heating exists of cooking, under the preceding topic of energy savings, provide a kind of hot half-gasification oven of three backhaul counter-burning type biomass superconductives rational in infrastructure, easy to use, sanitation and hygiene, multi-use when burning.
Problem solved by the invention is achieved through the following technical solutions:
Structure at first of the present invention comprises what several main parts such as body of heater, combustion chamber, storage compartment, heat-insulation layer, water jacket, super heat-conductive pipe, hot-water heating mouth, smoke tube mouth constituted.Its improvement is: 1) four oxygen supply burning is respectively to give wind twice before fire door, and wind is given twice in the furnace side, and behind the air intake, below water tank, in the burner hearth, there are two row's air inlets at the flame middle part, 3 gasifications of last row holes, 4 of next rows holes of gasifying; 2) with storage compartment and combustion chamber separately, dwindled the volume of combustion chamber, increased storage compartment's volume.3) storage compartment is built-in with the fuel slide plate, and after the biomass fuel in the combustion chamber burnouted, the fuel in the storage compartment can flow in the combustion chamber automatically.4) built-in four super heat-conductive pipes at the water jacket place that chimney links to each other with exhaust gases passes are welded on four jiaos of places, exhaust gases passes top with four super heat-conductive pipes, and the upper end places in the water jacket, and the lower end places in the flue; 5) welded the iron pipe that is connected with water jacket in exhaust gases passes, the absorption that it has increased heat in the flue gas has reduced the loss of heat.
The specific embodiment:
Shown in Figure 2 as Fig. 1, Fig. 1 Fig. 2 is a cutaway view of the present invention, and its structure is formed and comprised: storage compartment 1, combustion chamber 2, preceding anti-burning plate 3, air vent 4, wireway 5, fire grate 6, fuel slide plate 7, back anti-burning plate 8, fire sealing cover 9, iron pipe 10, flue 11, super heat-conductive pipe 12, chimney 13, combustion chamber bell 14, storing chamber cap 15, ash bucket 16, logical a heatable brick bed mouth 17 constitute.At first air vent 4 is opened, ash bucket 16 is pulled out a segment distance, adds a certain amount of fuel then in storage compartment 1, lights, and when treating that burning has certain fire in a stove before fuel is added, adds required fuel.During burning, be advanced into combustion chamber 2 under the flue gas, oxygen supply burning from the bottom to top, the wireway 5 of side flame and flame envelope in flame carry out the oxygen supply burning once more, be folded back behind the anti-burning plate 8 and carry out secondary to three after flue gas runs to and burn, fully gas fume after burning is passed through flue 11, the heat in the flue gas is absorbed with the super heat-conductive pipe that is connected with water jacket by the iron pipe 10 that is connected with water jacket, reduce heat to airborne discharging, play energy-conservation effect.The hot half-gasification oven of this three backhauls counter-burning type biomass superconductive also can be banked up a fire, and when banking up a fire, the fire sealing cover 9 of closing ash bucket 16, air vent 4, combustion zone and exhaust gases passes district can be effective.The difference of Fig. 1 Fig. 2 is that Fig. 2 is applied to logical a heatable brick bed area, the north more.
Fig. 3 Fig. 4 is four oxygen supply burning structures of the present invention figure, is respectively to give wind twice before fire door, and wind is given twice in the furnace side, and behind the air intake, below water tank, in the burner hearth, there are two row's air inlets at the flame middle part, 3 gasifications of last row holes, 4 of next rows holes of gasifying.
Fig. 5 Fig. 6 is the structure chart of super heat-conductive pipe of the present invention, its upper end places in the water jacket, the lower end places in the flue, utilize the fast characteristics of heat transfer rate, be delivered to the heat in the flue gas in the water jacket fast and effectively, its heat transfer rate is 1.5 times of the velocity of sound, and this design has improved the speed of conducting heat greatly, and the heating device is rapidly heated.
Fig. 5 still is an iron pipe part of the present invention, and its feature also is: welded the iron pipe that is connected with water jacket in exhaust gases passes, the absorption that it has increased heat in the flue gas has reduced the loss of heat.
Fig. 7 is the anti-structure charts that burn of three backhauls of the present invention, the flue gas that fuel produces in the burner hearth internal combustion carries out primary combustion, second-time burning, three burnings flowing into again through piping in the burner hearth, so repeatedly, gases such as carbon dioxide in the flue gas, sulfur dioxide are more fully burnt, reach the effect of energy-saving and emission-reduction.
Fig. 8 is the structure chart of fuel slide plate of the present invention, and the fuel slide plate places in the storage compartment, and after the biomass fuel in the combustion chamber burnouted, the fuel in the storage compartment can flow in the combustion chamber automatically.
Fig. 9 is the structure chart of burner hearth of the present invention inside, and storage compartment and combustion chamber are separated, and has dwindled the volume of combustion chamber, has increased storage compartment's volume, and fuel saving reaches 60%, and fire-sealing time reached more than 14 hours.
