Description

A pellet stove of nonpowered}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove, and more particularly, to a non-powered pellet stove capable of burning pellets for use as indoor heating or hot water in a house, will be.

Generally, for the purpose of moisture removal in the rainy season during the winter or when there is a high humidity, there is a space where people live such as houses, shopping malls and factories, a housing for raising livestock, or a vinyl house for cultivating crops such as fruits and vegetables The device will be installed.

The heating device is mainly a boiler using gas as fuel, a hot air fan using petroleum, or a fireplace using coal.

In addition to the high cost of fuel such as gas, petroleum or coal as described above, the cost of heating is increased due to a large amount of consumed in combustion. In addition, since the discharged combustion gas contains a large amount of harmful components, There was a problem of harm.

Thus, wood-pellet fuels, which are low in fuel cost and do not harm the environment and the human body, are in the spotlight. Wood pellets are eco-friendly products in which sawdust, which is a by-product of wood, is processed and dried, compressed and formed into pellets in the form of small granules at high temperature and pressure using a pelletizer, and the generation of carbon dioxide during combustion is reduced.

In addition, since the lignin component in the wood is melted and formed into a pellet shape without a separate additive in the molding process of the pellet, the manufacturing cost is reduced, and the cost is lower than the purchase cost of petroleum or coal used as fuel, , And a heating apparatus accordingly is also being developed.

On the other hand, the pellet furnace using the pellets as a fuel has a disadvantage that a separate power supply facility for driving a moving screw or the like provided in the fuel supply passage is required in order to supply the pellets waiting in the hopper to the combustion chamber. As a result, the pellets can not be supplied to the combustion chamber in a remote area where the power source is not installed, a house in a place or a vinyl house, which is disadvantageous in that practicality of the furnace is deteriorated.

When the pellets are incompletely burned from the hopper to the combustion chamber through the fuel supply passage, the pellets are filled in the fuel supply passageway, and the pellets are stored in the hopper by the sequential combustion of the pellets in the standby state. There is a problem in that there is a risk of fire.

Further, when the pellets are burned in the combustion chamber, the cold air for combustion flows from the outside when the pellets are burned in the combustion chamber because the complete burning of the pellets is difficult and the thermal efficiency is relatively lower than that of the hearth using gas or the like.

A non-powered furnace for pellet fuel is disclosed in Korean Patent Publication No. 10-2013-0112076.

The embodiment of the present invention relates to a non-powered pellet stove that minimizes soot generation by completely burning the pellets in a pellet stove using the pellets as fuel, increases the burning rate of the fuel, and increases the heat efficiency of the stove .

The embodiments of the present invention relate to a non-powered type pellet stove which can reduce the maintenance cost by supplying the pellets waiting in the hopper to the combustion chamber by the non-powered force, thereby requiring no external power source.

An embodiment of the present invention relates to a non-powered pellet stove for preventing flammability of pellets stored in a hopper by successive combustion of pellets in a fuel supply passage for supplying pellets discharged from a hopper to a combustion chamber .

In order to achieve the above and other objects of the present invention, a non-powered type pellet stove according to an embodiment of the present invention includes:

A main body having a combustion chamber, a door that can be opened and closed, a receptacle for collecting ashes of pellets combusted in the combustion chamber, and a flue for discharging the exhaust gas;

A roast trolley mounted on a diaphragm of the combustion chamber and in which the pellets supplied through the fuel supply passage are seated and burnt;

An air supply pipe installed in the combustion chamber of the main body and supplying external air for combustion to the combustion chamber from outside through a passage between the outer case of the main body and the side wall of the combustion chamber;

And a nozzle connected to the outlet of the air supply pipe and connected to the outlet of the air supply pipe and circulating in the combustion chamber external air for combustion supplied to the pellet for completely burning the pellets supplied to the roast tall to extend the residence time It features a non-powered pellet stove.

The non-powered type pellet stove according to the embodiment of the present invention configured as described above has the following advantages.

By circulating the outside air for combustion in the combustion chamber, the pellets are completely burned due to the convection phenomenon, thereby minimizing the occurrence of soot. Thus, it is eco-friendly and maximizes the heat efficiency by increasing the burning rate of the fuel.

In addition, since a moving screw, a screw conveyor, and the like for supplying pellets stored in the hopper to the combustion chamber are unnecessary, the pellets are supplied in a non-powered manner, minimizing the maintenance cost and minimizing the maintenance cost, You can supply heating.

In addition, since only a predetermined amount of pellets injected from the hopper into the fuel supply passage is burnt, the pellets stored in the hopper are prevented from being burned by the heat source of the pellets being burned to prevent the occurrence of fire, thereby ensuring practicality and reliability.
