Description

Firewood and coal dual-purpose energy-saving furnace

technical field

The utility model relates to a living stove, in particular to a dual-purpose energy-saving stove that can use firewood or coal as fuel.

Background technique

With the increase of my country's population and the in-depth development of industrialization, my country's energy supply is in a tense situation, and the vast rural areas have gradually bid farewell to long-term dependence on firewood or biomass (such as shrubs, straw, hay and leaves, etc.) The living mode of the main fuel began to use coal and liquefied petroleum gas as living fuels in large quantities. Although the living conditions have been improved, it has also brought energy problems that cannot be ignored. Non-renewable energy substances such as coal and liquefied petroleum gas are used as living fuels A large amount of consumption and cheap renewable biomass materials are abandoned, resulting in waste of renewable energy materials, which is not conducive to building a conservation-oriented society.

Patent document CN2711571 discloses an energy-saving furnace that can burn coal and firewood, including a furnace shell, a furnace rake, a feed port, an ash discharge port, a burner head and a flue, and an air inlet is provided on the outside of the furnace shell. The annular air box is provided with an air outlet ring connected with the annular air box and provided with several air outlet holes at the furnace mouth on the top of the furnace. Although this technical solution can use firewood or coal as the furnace fuel, in practical application, the heat and combustible particles in the furnace will leak out rapidly with the flue gas, the available thermal efficiency is not high, and the energy-saving effect is not obvious.

Contents of the invention

The purpose of the invention of the utility model is to provide a dual-purpose energy-saving furnace with good energy-saving effect, adjustable firepower, and clean and hygienic use. The further purpose is to provide a dual-purpose energy-saving furnace with firewood and coal that can generate hot water during use. Better adapt to the needs of the vast number of rural families, improve the practicality and economy of the product.

The technical solution adopted by the utility model is: a dual-purpose energy-saving furnace for firewood and coal, including a furnace cylinder and a furnace platform installed above the furnace cylinder. Ash port, the furnace tube above the furnace bridge is provided with a feed port with a sealing cover, a cooker seat is provided on the furnace platform, a flue exhaust duct is provided on the inner wall of the furnace platform, and it is connected with the smoke window head, and a flue regulator is installed on the smoke window head .

The flue regulator can include rotatable blades in the flue, the blades are connected to an external operable handle, and the angle of the blades in the flue can be changed by adjusting the position of the handle, thereby adjusting the ventilable cross-sectional area of the flue; the flue regulator It can also be an insert piece with a handle that can be twitched in the cross section of the flue, and the position of the insert piece can be adjusted to adjust the cross-sectional area of the flue that can be ventilated.

The ash discharge port and the feed port can undertake the air intake function of the furnace cylinder alone or at the same time. Therefore, the sealing covers of the two can be the sealing covers with the function of adjusting the intake air, such as a round cover with multiple ventilation holes on the side wall, a movable Rotate cover etc.

Firewood or coal can be sent to the furnace bridge in the inner cavity of the furnace barrel through the cooker seat on the hearth or the feed port for combustion. The cooker is placed on the cooker seat. When the firepower needs to be increased, the seal on the ash discharge port can be opened. Cover, or open the sealing cover of the feed port at the same time, to ensure the sufficient supply of fresh air in the inner chamber of the furnace, and at the same time adjust the flue regulator on the smokestack head to increase the ventilation cross-sectional area of the flue, and the fuel on the furnace bridge will quickly Entering the high-fire stage, the flame temperature is high and the firepower is fierce; when continuous high-fire is required, the flue regulator can be adjusted to appropriately reduce the cross-sectional area of the flue ventilation and slow down the exhaust speed of the flue, thereby slowing down the smoke caused by the inner chamber of the furnace. At this time, the concentration of combustible particles in the flame area of the inner chamber of the furnace chamber is high, the temperature is high, and the fuel consumption rate is small, the burning time is long, the heat efficiency is high, and the energy saving effect is obvious; When it is necessary to reduce the firepower, the flue regulator can be further adjusted to reduce the cross-sectional area of the flue ventilation, or at the same time reduce the air intake area of the ash discharge port and the feed port through the sealing cover, which can reduce the firepower of the inner cavity of the furnace cylinder; When the ash port and the feed port are all closed by the sealing cover, the fuel in the inner cavity of the furnace tube is in a smoldering state.

A water tank is arranged on the outer wall of the upper section of the furnace cylinder, and a water inlet and a water outlet are arranged on the water tank. When there is fuel burning in the furnace cylinder, the heat on the furnace cylinder can be transferred to the water tank outside, which continuously heats the water in the water tank to generate domestic hot water, which brings more convenience to family life. A water inlet and a water outlet are arranged on the water tank, which is convenient for taking hot water at any time, and is convenient for replenishing cold water in the water tank at any time. The water tank can be configured as a ring, or a square, or other shapes as required.

A detachable movable furnace core is arranged in the furnace cylinder. In order to better meet the combustion needs of coal-fired coal, especially the combustion needs of small-diameter formed briquettes, a detachable movable furnace core can be set in the furnace cylinder. Fill the non-combustible material between the outer wall of the furnace core and the inner wall of the furnace tube to fix the furnace core, and put the briquette into the furnace core to burn, which can get the same or even better combustion effect as the ordinary coal furnace; the non-combustible materials used for the fixed furnace core can be crushed slag, the material is easy to obtain and convenient to use.

A movable cover plate is arranged on the above-mentioned cooker seat. When no cooking utensils are placed on the cooking utensil seat, the movable cover plate can be placed to prevent the exhaust gas and dust in the furnace cylinder from leaking out, so as to keep the use environment clean and hygienic.

The above-mentioned feed port with a sealing cover can protrude obliquely upward from the furnace tube interface, so that users do not have to bend over too much when adding fuel from the feed port, so as to improve the convenience of use.

A base with a support surface larger than the cross-sectional area of the furnace cylinder is provided at the bottom of the furnace cylinder, which can improve the stability of the entire furnace body and prevent the furnace body from toppling when it is accidentally stressed.

The bottom of the above-mentioned water tank is provided with a supporting seat on the ground, which can improve the stability of the entire furnace body and prevent the furnace body from toppling when it is accidentally stressed.

The utility model adjusts the cross-sectional area of the flue by setting a flue regulator on the smoke exhaust channel, so that the fuel consumption is small, the thermal efficiency of the utilization is high, and the energy-saving effect is obvious; Hot water can be generated at any time, bringing more convenience to family life, and the product is economical and practical.
