Abstract
Description
The present invention is for the pellet boiler which can stir the pellets burned in the combustion vessel to facilitate the combustion of the pellets, and to provide air to the pellets are burned while stirring to prevent the heat of the pellets to be transferred to the outside Relates to a combustor.
In general, a boiler is a means of heating a water tank circulated for hot water and heating while the burner is operated by a control system such as an electric ignition method, and the fuel mainly uses oil or gas.
In the case of a boiler using such oil or gas as fuel, the burden of using the boiler is increasing in rural areas such as the income level is difficult because the cost of purchasing the fuel is excessive and the maintenance cost is high.
In view of these characteristics, it is a recent trend that a lot of boilers used as solid fuels such as coal, wood, and coal briquettes are spread in rural areas.
Most of the existing boilers using the solid fuel as described above simply burn fuel in the lower part of the hot water tank, so the heat loss through the outer wall of the combustion chamber is large, resulting in low overall thermal efficiency.
In addition, there is a disadvantage in that the overall life of the boiler is shortened, such as the parts around the combustion chamber are easily corroded due to exposure to high temperatures.
Recently, a large number of hot water boilers have been proposed in which the entire process such as fuel supply and combustion and discharge of combustion materials is automatically performed.
For example, anthracite coal or chaff sawdust, which is a particulate solid fuel, is automatically supplied to the combustion section by a transfer screw, and the solid fuel thus supplied is combusted in the combustion section, and at the same time, the ash generated after combustion is automatically generated by an ashtray device. Large-capacity hot water boilers that are discharged into the air are being used a lot. In addition, a lot of pellets (pellets) produced by processing chaff, sawdust, other sludge and the like are being used.
However, the boiler for burning the conventional pellets has a problem in that the combustion efficiency of the combustor is lowered because the impurities contained in the pellets that are burned in the combustor disposed in the combustion chamber are burned and fixed to the combustor.
In addition, the heat of the pellets that are combusted in the conventional combustor is also transmitted to the pellets supplied through the screw described above there is a problem that a fire occurs.
The present invention has been made to solve the above problems, and an object thereof is to provide a combustor for a pellet boiler which can easily burn pellets by stirring the pellets combusted in the combustion container.
Another object is to provide a combustor for a pellet boiler which can prevent the combustion heat from being transferred so that the combustion heat of the pellets that are combusted is not transmitted through the screw.
Furthermore, another object is to provide a combustor for a pellet boiler in which air supplied to the combustion container forms an air curtain by the structure of the combustion container so that the pellets burned in the combustion container can be completely burned.
In addition, it is possible to prevent the fire by blocking the pipe while separating the pipe supplied with the pellet.
