Description

Pellet Stove The present invention relates to a pellet stove, and more specifically, to a pellet stove that naturally induces the falling of pellets to allow for prolonged combustion of the pellets, controls the temperature resulting from the combustion of the pellets by adjusting the amount of falling pellets, ensures high combustion efficiency by collecting the ash generated from the combustion of the pellets in an ash tray, and prevents backfire without the need for separate power energy input by forming an airflow according to the inflow of air. As the burden of fuel costs increases due to rising oil prices, there is a growing trend among factories and farms that previously used diesel or anthracite coal for heating to use wood-based pellets instead of coal to reduce fuel expenses. Pellet is a product made by crushing and drying plants or wood into small particles, such as sawdust, and compressing them into a uniform size without the use of adhesives; it is widely used as fuel for heating and power generation. Accordingly, various technologies for pellet stoves that use pellets as fuel have been developed. Among stoves that use pellets as fuel, a functional non-powered pellet stove is disclosed in Registered Patent Publication No. 10-2385354 as a technology for non-powered pellet stoves. The above technology comprises: a stove body forming a space for burning pellets as raw material; a chimney connected to one side of the stove body and discharging smoke generated during combustion; a pellet feeding hopper for feeding pellets into the stove body; a pellet supply line section having one end communicating with the pellet feeding hopper and the other end disposed within the stove body, supplying pellets within the pellet feeding hopper; an air supply line section disposed radially outside the pellet supply line section and supplying external air to the stove body; and a pellet dispersion unit disposed within the stove body at a location adjacent to the lower portion of the pellet supply line section and dispersing pellets supplied from the pellet supply line section. In addition, a non-powered pellet stove is disclosed in Registered Patent Publication No. 10-1793182. The above technology comprises: a main body equipped with a combustion chamber, an openable door, an ash tray for receiving and collecting ash from pellets burned in the combustion chamber, and a flue for exhaust gas discharge; a hopper connected to the combustion chamber through a fuel supply passage and storing pellets supplied to the combustion chamber, wherein the fuel supply passage is formed at an angle so that the pellets discharged from the hopper are supplied to the combustion chamber by their own weight and the inclination of the passage; a roast stall mounted on a diaphragm of the combustion chamber, upon which pellets supplied through the fuel supply passage are placed and burned; an air supply pipe mounted in the combustion chamber of the main body and for supplying external combustion air, which is introduced from the outside through a passage between the outer casing of the main body and the side wall of the combustion chamber, to the combustion chamber; and a nozzle connected to the outlet of the air supply pipe and configured to extend the residence time by circulating the external combustion air supplied to the pellets within the combustion chamber to ensure complete combustion of the pellets supplied to the roast stall. However, in conventional pellet stoves, the means of controlling the combustion temperature is generally by controlling the amount of air entering. In other words, the means of controlling the temperature of a pellet stove is to regulate the amount of air supplied to the combustion chamber. As the amount of air supplied increases, the temperature of the combustion chamber rises. However, this method of controlling heat output (temperature) by adjusting the amount of air can lead to incomplete combustion due to a lack of oxygen, resulting in reduced thermal efficiency and fuel waste. Additionally, incomplete combustion causes soot to accumulate inside the stove, which reduces heat transfer, shortens the cleaning cycle, and can reduce the durability of the stove. In addition, precise temperature control is difficult, and response to rapid temperature changes is slow. In addition, ash is generated by the combustion of pellets; if this ash accumulates, the flame weakens and heat radiation decreases, resulting in lower thermal efficiency and the disadvantage that flashback may occur.
