Abstract
The utility model relates to an indoor smokeless fuel-saving stove which comprises a stove body. A stove chamber, a stove door, a smoke outlet and a discharge flue are arranged on the stove body; and the smoke outlet is formed on one side of the stove door and communicated with an outdoor chimney through the discharge flue and is higher than the stove door. The utility model has the advantages that the smoke outlet is preposed nearby the stove door, so that the smoke reversely flows, the travel of smoke in the stove is increased, the discharge temperature is reduced, and the thermal efficiency is improved; because a negative pressure source at the smoke outlet is closer to the stove door, the pressure difference is larger, the discharge capacity is strong, and airflow entering the stove door can block smoke overflow so as to ensure smaller possibility of diffusing the smoke to indoor and obvious effect of reducing or avoiding indoor air pollution; and the indoor smokeless fuel-saving stove has less fuel used, easy fire lighting, high fuel utilization, concentrated fire, high thermal efficiency, quick temperature rising speed. The utility model is an ideal stove for rural households.
Description
Technical field
The utility model relates to a kind of kitchen range, is specifically related to a kind of indoor smokeless fuel saving stove.
Background technology
Biomass fuel combustion discharges a large amount of harmful substances, comprises particle, carbon monoxide, polycyclic aromatic hydrocarbon, sulfur dioxide, nitrogen oxide, group compounds of aldehydes and ketones etc., not only room air is polluted, and the health of human body is impacted.The room air pollution that biomass fuel combustion caused is a global health problem, can cause annual 1600000 premature deaths according to estimates.According to World Health Organization calendar year 2001, about in the world 50% population and the developing country rural households more than 90% still use firewood, animal wastes and the crop material handled without processing to act as a fuel.These materials burn in indoor naked light or the simple cooking stove of function, cause air height to be polluted, and women's (particularly be responsible for cook women) and children's exposure are the most serious.
For a long time, what China peasant used is old-fashioned traditional kitchen range, directly burning crop straws, fuel wood and coal.Exist: the thermal efficiency low (8～12%), Fuel Consumption is big; The 2nd, intensity is low, a little less than the firepower, and poor performance; The 3rd, operating condition is poor, time-consuming, effort; Particularly the flue dust in the chamber of a kitchen range can be emerged from the kitchen range door, can produce a large amount of air nuisances and be dispersed into indoorly, causes aspect problems such as IAQ is abominable.
The utility model content
The technical problems to be solved in the utility model provides the high indoor smokeless fuel saving stove of a kind of utilization efficiency of heat energy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of indoor smokeless fuel saving stove comprises stove, and this stove is provided with the chamber of a kitchen range, kitchen range door, exhaust opening, smokejack, and described exhaust opening is arranged on kitchen range door one side, and smoke vent position is higher than the kitchen range door, and this exhaust opening is communicated to outdoor chimney by smokejack.
Described kitchen range door upper edge is lower than kitchen range pot pot navel, or maintains an equal level with the pot navel.
Described stove also is provided with the kitchen range grate, and its installation site is that the upright projection point on chamber of a kitchen range bottom surface with the pot navel is the center, kitchen range grate length overall 1/5～1/3 towards exhaust opening, 4/5～2/3 exhaust opening dorsad.The kitchen range grate is arranged on from a chimney side far away, the position of flame also can correspondingly be moved far from chimney so, so just, increased high-temperature flue gas in lead to the process of chimney with the contacting of pot, through after long distance and the pot generation heat exchange, the temperature of flue gas can be even lower, and heat energy utilization is more abundant.
The described chamber of a kitchen range comprises the combustion chamber and at the air-returen flue above the combustion chamber and between below the pot.
Air-returen flue is meant above the combustion chamber and the space between the below of pot, it is the passage that connects combustion chamber and exhaust opening, unburned fuel gas burns away at this, make high-temperature flue gas and pot proceed heat exchange, thereby make full use of the heat of flue gas, its shape and the thermal efficiency are irrelevant, but must keep gas flow unobstructed.The air-returen flue of soft bavin kitchen range should be designed to the single-order ladder type, and the air-returen flue of hard bavin kitchen range can be designed to two ladders or single-order ladder type.
The described chamber of a kitchen range is the cylindrical of inner wall smooth, or is taper type, or is bowl-type, or is the class cydariform, and the center of combustion chamber coincides with a pot navel.
Chamber of a kitchen range shape is wanted rationally, with the flow velocity and the flow direction of control high temperature gas flow, makes high-temperature gas and pot carry out sufficient heat exchange simultaneously the bottom of the reflect radiation heat of fuel combustion to pot; The smooth heat radiation that is beneficial to is wanted on the surface of the chamber of a kitchen range, reduces the air current flow resistance; Chamber of a kitchen range material will have good heat insulating ability and fire resistance.As, the advantage of class drum shape is that the internal face of combustion chamber is a sphere, high-temperature fuel gas can be along spheric motion during burning, and contact with the normal of pot, make to have prolonged the time of high-temperature fuel gas, improved the thermal efficiency, simultaneously with the thermal convection current of pot, the sphere wall of combustion chamber can further improve the temperature of pot being radiated its surperficial reflect heat to the bottom of a pan again.This combustion-chamber shape can also be used pluralities of fuel, and adaptability is better.
Described combustion chamber to hang fire highly be 100～200mm, combustion chamber volume 0.004～0.017m
3, air-returen flue volume 0.007～0.01m
3, exhaust opening sectional area 80～150cm
2
During chamber of a kitchen range design certain volume to be arranged, supply with to guarantee the needed air appropriateness of fuel combustion.
Exhaust opening is the passage of air scavenge, and the exhaust opening cross section is little, the flue gas flow rate height in this cross section of flowing through, and the negative pressure of generation increases suction draught to a certain extent, help burning, but the cross section is too small, is unfavorable for burning, and above-mentioned size is more suitable.
Be provided with the waste-heated water-tank above described exhaust opening, the smokejack of being made by metal material is communicated to outdoor chimney behind this waste-heated water-tank.
The baffle plate of movable band peep hole is installed on the described kitchen range door.
Zone near burner hearth in described stove is provided with baking box.Further expand the function of combustion bavin kitchen range.
Along the burner hearth periphery heating water tank is set in the described stove interlayer, this heating water tank is provided with entery and delivery port.Can solve the problem (especially in the winter time make) of rural households with the hot water inconvenience.
The utility model can a plurality ofly be used in combination as the stove unit, can shared same smokejack.
The utlity model has actively useful effect:
1. exhaust opening is prepended near the kitchen range door, the one, but smoke backflow, increase the interior stroke of kitchen range of flue gas, reduce exhaust gas temperature, improve the thermal efficiency, the 2nd, the negative pressure source at exhaust opening place is nearer apart from the kitchen range door, pressure differential is bigger, and the smoking ability is strong, and the air-flow that enters the kitchen range door can stop that flue gas is excessive, it is less to make flue gas be dispersed into indoor possibility, alleviates or avoids the effect of room air pollution remarkable.
2. few with bavin, light a fire easily, the fuel availability height, firepower is concentrated, thermal efficiency height, programming rate is fast, is the desirable kitchen range of rural peasant household.
