Abstract
The utility model discloses a furnace core. The furnace core is composed of a furnace bridge (4), a combustion chamber (2), a fire-baffle ring (1) and a separation board (3). The furnace bridge (4) is horizontally placed, and one end of the furnace bridge (4), close to a furnace door, is higher. The combustion chamber (2) is of a big-end-down pyramid type. The fire-baffle ring (1) is made of yellow mud, coal ash, hair and the like, the distance from the fire-baffle ring (1) to the pot bottom is 5mm-30mm, the portion of the fire-baffle ring (1), close to a chimney, is the lowest, the portion of the fire-baffle ring (1), opposite to the chimney, is the highest, and then heights are reduced gradually. The separation board (3) is of a pyramid type and is installed in the middle above the combustion chamber (2) of the furnace core, the height of the separation board (3) is 3cm, and two rows of oxygen supply holes are formed in the separation board (3). The furnace core enables fuel to be combusted fully, heat preservation effect is good, heat energy use ratios are high, and therefore the fuel is saved, and exhaust emission is reduced. Thus, the furnace core is suitable for use in households of towns and villages.
Description
Technical field
Originally relate to utility model and cooking stove, specifically, relate to the combustion chamber of solid-fuelled domestic burners.
Background technology
Cooking stove is people's indispensable apparatus of living.The structure of cooking stove and efficiency of combustion thereof and fuel consumption are people's problems of concerns always.Be fuel saving, the raising thermal efficiency, people have carried out large quantity research to cooking stove, have also designed various stove and accessorys and kitchen range.
Guizhou Province's Qiandongnan Prefecture of Guizhou Province natural, ecological is preserved better, and afforestation rate is high, and still, working condition is poor, low productivity, lag of economic development, peasant's per capita income is lower than the whole province's mean value, and the colliery resource is few, it is wideless to distribute, and reserves are not enough, and agricultural cooking stove fuel is mostly with Chai Weizhu.Therefore, research applying biological matter high-efficiency, low-emission and energy-saving fuel saving stove to reducing environmental pollution, reduces the deforestation amount, preserves the ecological environment, and energy-saving and emission-reduction synergy has extremely important realistic meaning and far-reaching historic significance.
Through retrieval, specially for related application such as application number 201120066340.6 " a kind of fuel saving stove ", 201020570426.8 " energy-saving firewood ranges " etc. of the special-purpose cooking stove of faggot, stalk design, effect may be better, but structure is still comparatively complicated.
Summary of the invention
The purpose of this utility model is to provide a kind of combustion chamber, to overcome the deficiencies in the prior art, not only can solve better the heat energy utilization problem of bavin fuel, also has very simple structure.
The combustion chamber that the designer provides has following characteristics: this combustion chamber is installed in shaft inside; It comprises grate, combustion chamber, fire-stop ring and dividing plate; Wherein grate is formed by cast iron casting, is of a size of 16*20cm, is traverse, and is slightly high near a side of kitchen range door; Large little pyramid type under being of combustion chamber, the diameter of bottom is 24-25cm, the diameter on top is 21-22cm, high 12-14cm; Fire-stop ring adopts the making such as yellow mud, coal ash and hair, is 5-30mm apart from the distance in the bottom of a pan, and minimum near the chimney place, offside is the highest, successively decreases successively; Dividing plate is conical,
InstallIn the combustion chamber of combustion chamber upper center, height is 3-4cm, is provided with two row's oxygen supply holes.
Above-mentioned grate is 16-18cm to the distance in the bottom of a pan.
The kitchen range door is positioned at upper limb than the low 3cm of outlet flue, and wide is 16cm, high 14cm.
Above-mentioned combustion chamber periphery has heat-insulation layer.
Combustion chamber of the present utility model is compared with old-fashioned firewood-saving stove, has reduced the volume of combustion chamber, can reduce the input of fuel, thereby reduces the use of fuel, has set up heat-insulation layer, and heat-insulation layer can reduce the heat absorption of combustion chamber, is that heat energy obtains utilizing more fully.Grate is more reasonable to the distance in the bottom of a pan, has avoided the excessive height of old-fashioned firewood-saving stove but a large amount of heat energy consumes in vain.The oxygen supply hole of dividing plate can be the imflammable gas that produces in combustion process of fuel such as CO, CO
2, CH
4, SO
2Mix mutually with oxygen Deng when not leaving the combustion chamber, in the thermal-flame of combustion chamber, burn away, make fuel combustion more abundant, reduced the discharging of waste gas.Fire-stop ring the mass rate of emission that can reduce hot-air is set, thereby the more effective thermal source that utilizes improves the thermal efficiency.
Therefore, adopt combustion chamber of the present utility model to make fuel combustion abundant, heat insulation effect is good, and heat utilization rate is high, thus fuel savings and reduced toxic emission.Be applicable to cities and towns and Rural Families.
