Abstract
The utility model discloses an efficient emission-reducing firewood/coal energy-saving furnace, which comprises a furnace surface (1). A furnace chamber (2) is arranged under the furnace surface (1); the lower end of the furnace chamber (2) is connected with a furnace core (3); an ash can (4) is arranged under the furnace core (3); a smoke outlet connected with the furnace chamber (2) is arranged on the furnace surface (1); a secondary air inlet hole (5) is arranged at the side part of the furnace chamber (2); a secondary air channel (6) is arranged at the outer periphery of the furnace core (3) and the furnace chamber (2); and a secondary air inlet is arranged on the contact surface between the secondary air channel (6) and the ash can (4). In the utility model, when the imperfect-combustion smoke in the furnace chamber rises to the secondary air inlet hole to meet secondary inlet air, the imperfect-combustion smoke is rapidly lighted to continue burning under the condition of sufficient oxygen to release a lot of heat, therefore, the burn-off rate of fuels and the heat efficiency are greatly increased for the furnace provided by the utility model, and the emission of harmful gas is reduced.
Description
Technical field
The utility model relates to a kind of domestic briquet stove, particularly relates to the energy-conservation stove of a kind of efficient reduction of discharging bavin coal.
Background technology
Existing common family expenses coal-fired and firewood-fired stove is made as air return stove more, its objective is increases the flue gas recirculation path, increase the heat-obtaining effect, but in actual applications, southwest particularly, the coal-fired and firewood-fired stove all can be used throughout the year, winter, temperature was lower, the distributing of its heat helps and warms oneself, but summer existing air return stove flue is connected on the ash bin, like this with the circulating path that has increased flue gas but because of the change of its flue makes in the stove obviously anoxic, cause fuel combustion insufficient, problems such as it is more to exist heat to scatter and disappear, and heat utilization efficiency is lower.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of energy utilization rate height, heat loss is low, heating is effective, the multiple functional energy-conservation stove of efficient reduction of discharging bavin coal are provided, can overcome the deficiencies in the prior art.
The technical solution of the utility model; It comprises boiler face, below boiler face, be provided with burner hearth, be connected with combustion chamber in the burner hearth lower end, below combustion chamber, be provided with ash bin, on boiler face, be provided with the outlet flue that is connected with burner hearth, sidepiece at burner hearth offers secondary intake opening, is provided with secondary air duct in the periphery of combustion chamber and burner hearth, is provided with the secondary air mouth on the contact-making surface of secondary air duct and ash bin.
Periphery at secondary air duct is provided with the hot water layer, is provided with water inlet at hot water layer's epimere, hypomere is provided with delivery port.
Periphery the hot water layer is provided with heat-insulation layer,
Sidepiece at combustion chamber offers bavin coal interpolation mouth, adds on the mouth being provided with cover plate at the bavin coal.
In the wherein side of burner hearth or be provided with food hot digestion case more than the side.
Be provided with steam (vapor) outlet on the hot water layer, steam (vapor) outlet is connected with food hot digestion case.
Between ash bin and grate, be plugged with air-flow plate.
Compared with the prior art, the utility model offers secondary intake opening by the sidepiece at burner hearth, periphery at combustion chamber and burner hearth is provided with secondary air duct, on the contact-making surface of secondary air duct and ash bin, be provided with the secondary air mouth, when rising to the secondary intake opening place, the interior imperfect combustion flue gas of burner hearth runs into secondary air like this, imperfect combustion flue gas is lighted rapidly to burn away and is emitted a large amount of heats under the situation of oxygen abundance, thereby fuel burn-off rate, the thermal efficiency of this stove are increased substantially, and can reduce discharge of harmful gases.Secondary air duct is set outside secondary intake opening, secondary wind is entered by the lower end of secondary air duct, the cold wind that enters so just can be heated in running, help the burning of flue gas, periphery at secondary air duct is provided with the hot water layer, epimere the hot water layer is provided with water inlet, hypomere is provided with delivery port, so just the heat that can utilize combustion chamber to give out comes the cold water in the hot water layer is heated, can further improve heat utilization efficiency, also make things convenient for the user to use hot water at any time, periphery the hot water layer is provided with heat-insulation layer, can reduce hot water layer's heat leakage like this.Sidepiece at combustion chamber offers bavin coal interpolation mouth, on bavin coal interpolation mouth, be provided with cover plate, pot can be taken away so in use, sustainable reinforced, reduce soot emissions, much cleaner more environmental protection, by regulating the size of smoke pipe upper wind door, can conveniently control the firepower size, in the wherein side of burner hearth or be provided with food hot digestion case more than the side, this case and baking box function are similar, can make things convenient for hot meal, cook; Between ash bin and grate, be plugged with air-flow plate, so just can control the air intake size, thereby further control the firepower size, by control upper and lower part intake size the flame in the combustion chamber is burnt from the top down simultaneously by the plug air-flow plate.The utility model is fit to add all kinds of comburants simultaneously, as stalk, bavin firewood.Branch, forest waste material, excrement of animals, corncob, raw coal etc., very convenient, practical, have excellent popularization and be worth.
