Description

Wood pellet boiler {A Boiler for wood pellet}

The present invention relates to a wood pellet boiler, and more particularly, to improve a boiler that burns wood residue by compression molding pellet fuel, which is economical and environmentally friendly, and has high thermal efficiency and combustion residue (ash). The wood pellet boiler is easy to process.

Generally, boilers are used to supply heating water and hot water in homes, offices, factories, and plastic houses. These boilers have high thermal efficiency and do not leave ash after combustion. Is widely used.

The use of such oil boilers or gas boilers has caused economic difficulties due to increased fuel costs such as oil and gas. Especially in rural, mountainous, and walled areas where economic conditions are inconvenient, economic problems due to increased fuel costs as well as their installation and operation are difficult. It was a situation.

In addition, fossil fuels used in oil boilers and gas boilers act as important sources of global environmental pollution, including air pollution, due to natural vapors from the exhaust gases generated during combustion or from oil storage tanks.

Recently, a tendency to use boilers using various pellet fuels, including wood as well as biomass, in general farms and factories used for home or small-scale business is increasing. .

Pellets used as fuel for boilers are fuel produced by crushing bark, sawdust or thinning twigs left after wood processing at sawmills, etc., and emit significantly less carbon dioxide than fossil fuels such as coal and petroleum. There is almost no heat, and relatively high calories are emerging as an eco-friendly fuel, and the consumption of heating or hot water boiler fuel in rural or urban areas is increasing.

The prior art related to the present invention discloses a pellet fuel supply and combustion device for the boiler of the Utility Model Publication No. 20-2009-0007901, which is the fuel of the block-shaped body formed a fuel supply path for communicating the upper surface supply port and the side inlet port A supply unit; A combustion part of the duct-type body which is positioned and connected to the side inlet side of the fuel supply part and whose front end and side are open; A first screw installed in the fuel supply path of the fuel supply part toward the side inlet, and a first motor for controlling the operation of the first screw; A fuel supply pipe having one end connected to an upper surface supply port of the fuel supply part and the other end connected to an end portion of a fuel transfer pipe having a second screw for transferring pellet fuel from a pellet fuel storage tank; A second motor for controlling the operation of the second screw; A heater for supplying heat for combustion of pellet fuel introduced into the combustion unit; The fan is provided for supplying air to help the combustion of the pellet fuel in the combustion section, and the pellet fuel is introduced into the combustion section because the pellet fuel is introduced laterally in the combustion section in a separate process of the first supply and the second input. It is possible to increase safety and to increase efficiency of pellet fuel supply and combustion.

On the other hand, in the above-mentioned conventional pellet boiler, the feed amount of the pellet is purely determined by the rotational speed of the first and second screws, and the bottom of the combustion part body is made of a simple duct type with a flat bottom, so that the amount of pellet supplied to the combustion part is lower in summer. In the winter, it needed a lot of calories in winter, so much more had to be added than in summer.

 In addition, the pellets supplied to the combustion section had to be combusted in a uniformly dispersed state in the combustion section, but when pellets were supplied in the lateral direction by the second screw, the pellets were not uniformly dispersed in the combustion section and thus concentrated in one place. Something happened.

In addition, in the conventional pellet boiler, since the combustion chamber cannot maintain a high temperature, the pellet is incompletely burned and burned, but a lot of ash is generated.

Therefore, the inside of the combustion section needs to be cleaned periodically or there is a problem of emission of pollutants through the exhaust gas, and in particular, the sludge (ash) due to incomplete combustion is stuck to the inside of the combustion chamber, so that the heat exchange efficiency is gradually decreased. .

 In addition, the conventional pellet boiler has a problem that the blowing blown by the side is caused by the wind blown in the state that the pellet is not burned.

The use of pellet fuel in such a boiler has the advantage of being more economical and environmentally friendly than the use of oil or gas, but the thermal efficiency of operating the boiler if the residue is not properly processed due to ash or the like as described above.
