Abstract

The present invention relates to a pellet stove, wherein the pellet stove body (10) is composed of a pellet supply unit, a combustion unit, an ignition unit, a dust removal unit, a waste heat recycling unit, and a control unit, and solids are generated by ash when the pellets are burned in the furnace. Therefore, if the size of the solids is large enough to block the air supply pipe, the agitator impeller is installed to prevent the size of the solid, so that sufficient air (oxygen) is supplied from the air supply pipe to complete combustion, and the remaining dust is transported together with the combustion gas and the cyclone In dust, the dust collects in a bucket and only the combustion gas provides a pellet stove that recycles waste heat through the outlet.

Description

Pellet Stove {Pellet Stove}

In the technical field of the pellet stove according to the present invention, it is a general idea that a stove using pellets as fuel is completely burned out of dust and gas generated and discharged to the atmosphere through the flue. It is a technology that recycles waste heat from exhaust gas after separating and removing from cyclone to fine dust.

Most of the stoves using pellet fuel are used to supply air (oxygen) to the fan by using a heater and hot air as a means for igniting the fuel supply pipe and fuel to burn the pellets in the combustion chamber. In the first place, the fuel and air (oxygen) supply ratio is appropriately combusted, but combustion is good, but the ash contained in the pellet fuel becomes small sintered particles due to high heat and grows in size as time passes. Since the air supply pipe for supplying (oxygen) is blocked, the supply of oxygen (oxygen) required for combustion decreases, resulting in non-combustion, and a phenomenon in which the pressure of the air supplied from the pen does not pass into the combustion chamber but flows backward. . In addition, exhaust gases and dusts are discharged to the outside air through the year, which causes pollution.

In the present invention, the ash contained in the fuel components in the pellet-burning stove is gradually increased in size as the ash remaining during combustion solidifies, the air supplied from the air (oxygen) supply pipe is larger than the hole of the perforated plate in the combustion furnace ( Oxygen) is a factor that hinders supply, and it is a problem to solve the factor of air pollution by exhausting dust and the like into the atmosphere through the flue of fuel (pellets) burning and generated.

In order to solve in the present invention, in order to suppress the generation of solids contained in the pellet fuel during combustion, a stirring impeller is installed at the center of the combustion furnace to rotate the 3RPM to burn the pellet and the remaining solid fine particles as dust. In order to maximize the wind speed that can be discharged to the upper part, the air hole at the bottom of the combustion furnace is not blocked and the combustion gas discharged through the upper part of the combustion chamber such as dust and combustion gas is completely removed by using cyclone to prevent air pollution. In addition, it is a method of increasing the thermal efficiency by recycling the waste heat of the exhaust gas is removed dust.

The effect of the present invention is that the ash from the fuel component is sintered during combustion of the pellet fuel in the combustion furnace to grow into large particles, so that the air supplied from the air supply chamber is reduced, so that smoke and solids are generated due to incombustible combustion. It is combusted and discharged like combustion gas in a fine ash state to increase combustion efficiency, and components such as soot and dust are collected by a cyclone to be a clean exhaust gas, thereby recycling waste heat indoors.

2 is a configuration diagram of the impeller for agitating the combustion furnace according to FIG. 1
3 is a configuration diagram of a combustion chamber and a cyclone in the present invention
4 is an explanatory view of the configuration of a pellet stove according to the present invention.

Detailed description of the pellet stove according to the present invention will be described in detail with reference to the drawing shown in Figure 1 pellet stove body 10 is composed of a pellet supply unit, combustion unit, ignition unit, dust removal unit, waste heat recycling unit control and pellet supply unit After supplying a certain amount of pellets to the hopper 20 and operating the motor 30-1 of the screw conveyor 30, the pellets are transferred by the screw conveyor 30 and lowered by the guide plate 30-2 at the inlet of the combustion chamber. When supplied to the combustion furnace 40-1, the heater 50-2 in the ignition unit is turned on while the temperature rises to 300 ~ 500 ℃ Pen motor is turned on to blow air (oxygen) to the ignition unit In the main surface, the pellets in the furnace are ignited and combustion starts. After a certain time, only the heater is turned off and the pen motor is kept on.

In the combustion section, while the pellet fuel supplied to the combustion furnace 40-1 is ignited and combustion starts, the stirrer impeller 60-1 rotates 3 RPM at a minute when the solids of ash generated during combustion are fine. When the pellet fuel is agitated, the fine ash mass rises to the upper part of the combustion chamber 40-3 by the air (oxygen) pressure supplied from the fan motor, and is discharged together with the combustion gas and the body 10 is discharged by the temperature of the discharged gas. ) Serves to transfer heat, and the combustion gas to be transferred to the cyclone, which is a dust removal unit, passes through the combustion chamber upper portion 40-3 and through the combustion gas transfer pipe 40-5 located at the outer lower portion of the combustion chamber body 30 to the cyclone inlet. After the dust is completely removed from the cyclone 70, the dust is discharged at half level to the water tank 70-4 in the dust collecting container 70-3 at the bottom. To collect dust and exhaust gases to the upper It relates to a stove using pellet fuel for supplying waste heat to the room through the outlet (70-2) for recycling.

2 is a matter related to the combustion furnace 40-1 and the stirring impeller 60-1. When pellets are supplied to the combustion furnace, the heater is turned on and the temperature rises to 300 to 500 ° C. When the motor is turned on to supply air (oxygen), a heat source is supplied from the heater 50-2, and the air at 300 to 500 ° C ignites the pellet to promote combustion, and as the combustion proceeds continuously, the ash as a pellet component becomes solid. In the air supply chamber 40-5, the hole of the lower perforated plate 40-3 does not become large enough to block the ash solids, and the ash solids are raised as the combustion gas by the amount of air (oxygen) wind supplied from the air supply chamber. To send it to the upper part of the combustion chamber (40-3)

3 shows the construction of the combustion chamber and the cyclone. The dust and the combustion gas flow through the upper part of the combustion chamber 40-3 and flow into the combustion gas transfer pipe 40-6 installed in the lower part of the combustion chamber 40. The combustion gas which is transferred to the inlet 70-1 and separated from the cyclone body 70 is collected in the water tank 70-4 inside the dust collecting container 70-3, and the treated combustion gas is discharged to the upper portion 70-. Through 2) it is a structure that can recycle waste heat.

4 is explanatory drawing comprised in the pellet stove in this invention.
