Description

Pellet boiler for pellet boilers {A burner pellet of boiler pellet}

The present invention relates to a pellet combustor of a pellet boiler, and more particularly, to efficiently perform ignition and combustion of pellets in a combustion chamber of a pellet boiler, and to simplify the manufacture of a pellet combustor and installation in a combustion chamber of a pellet boiler.

In general, a pellet boiler compresses wood or waste wood, uses pellets made of particles of a standard fuel, supplies the pellets to a combustion chamber of the boiler, burns them, and heats the water in the bath with the thermal power generated by the combustion to be connected to a heating pipe. The hot water heated or heated is used for household chores such as bathing and laundry.

The pellet boiler has a lower fuel cost than oil and gas (LPG, LNG), so it is easy to use in rural areas, and demand is gradually increasing.

In the pellet boiler, the pellets are supplied to the combustion chamber to ignite, and the electric heater is generally installed below the pellets supplied to the combustion chamber to ignite, and the blower supplies external air to the combustion chamber.

The above means has a drawback in that it takes a long time to ignite because the air supply and distribution suitable for ignition and combustion are not made to the pellets, and the smoke is generated badly at the beginning of the ignition because the air distribution and the ignition temperature are not suitable for the pellets. .

Prior means for the pellet boiler is as follows.

To the ignition heater receiving tube (2a) of the combustor main body as shown in the rectangular bar shape as shown in Figs. 2 and 3, the coil-shaped spring (4a) is connected to the power connection side of the ignition heater (4), the other side The ignition heater 4 of the igniter main body as shown in FIG. A fixed plate on the other side of the housing, and the ignition heater receiving tube (2a) (5) is provided configured to combine with the bolt 8 and the nut (8a) on the inner wall of the blower (6) the channel (7).

In the drawings, reference numeral 50 is a pellet boiler, 51 is a pellet supply port, 52 is a combustion chamber, 53 is a water tank, 54 is a combustion gas induction pipe, 55 is a return, 56 is a year, 57 is a supplementary year, and 58 is a heating tube. , 60 represents pellets.

As described above, in the present invention, when the pellet combustor of the present invention is installed in the combustion chamber of the pellet boiler, the pellet is introduced into the conical container of the combustor main body, and external air is introduced into the conical container and the vent through the air inlet through the air inlet. If the ignition heater of the air inlet pipe is heated in the inflow state and the heating tube is heated, the pellet is ignited in the heating tube. If the ignition heater is turned off after ignition, the air is blown from the vent of the conical container to the inner pellet. The combustion is smoothed, so that the smoke generated by ignition and combustion is not reduced, and the pellet combustor has an optimal ignition and combustion space because the conical container into which the pellet is introduced and the air holding space for supplying the outside air are standardized. Being able to be and the specification has the advantage of being easy to manufacture and install.

Hereinafter, specific embodiments of the present invention will be described.

In the present invention, as shown in FIG. It is formed, overlapping so that the air attracting space (H) is formed between the cylindrical tube (1) and the conical container (1a) is configured by welding the edge portion to be integral, and the air inlet on one side of the cylindrical tube (1) (2), an ignition heater accommodating tube (2a) is formed at the center thereof extending into the conical container (1a), and a combustion tube (3) is provided at the tip of the ignition heater accommodating tube (2a). The combustor main body includes a conical container (1a) in which pellets are stored and combusted, an air inlet (2) into which outside air is introduced, a cylindrical tube (1), and an air inlet space between the conical container (1a) Since H) is standardized, manufacturing is easy.

In addition, the ignition heater accommodated in the ignition heater receiving tube (2a) of the combustor body is connected to the coiled spring (4a) to the power connection side of the ignition heater (4), as shown in Figures 2 and 3, the spring (4a) The other side of the fixing plate 5 is fitted into the locking groove 5a, and the ignition heater 4 is inserted into the ignition heater accommodating tube 2a as shown in FIG. 4, and the other fixing plate 5 is a blower 6. When combined with the bolt (8) and the nut (8a) to the inner wall of the pipe (7) of the) configuration is simple and convenient to use.

The pellet combustor configured as described above is normally installed in the combustion chamber 52 of the pellet boiler 50 as shown in FIG. 5, the pellet supply port 51 is supplied with the pellets 60, and the blower 6 and the ignition heater ( 4) When the power is supplied, the external air of the blower 6 flows into the air inlet 2 and the ignition heater receiving tube 2a below the cylindrical tube 1 through the tube 7 and the cylindrical tube 1 In the air holding space (H) between the conical container (1a) and conical through the upper (a) of the conical container (1a), the intermediate portion (b), and the vent hole (1b) formed in the bottom (c) It spreads inside the container 1a and air flows into the pellets.

In addition, the ignition heater (4) is heated while being heated is blown into the heating tube (3) of the tip and the heating tube (3) is heated, the hot air is distributed in the pellets around the heating tube (3) is ignited.

When the ignition heater 4 is heated for a predetermined time to ignite the pellet, the ignition heater 4 is turned off, and the external air blown by the blower 6 is passed through the conical container 1a in the air holding space H. Combustion is made by air diffused inward from the pores 1b.

If the number of revolutions of the blower 6 is set in stages above, the amount of air blown at the initial stage of ignition is increased, and the amount of air blown at the time of combustion increases.

When the pellets are burned in the conical container 1a constituting the pellet combustor as described above, the combustion thermal power and smoke and the burned pellets are vertically raised in the combustion chamber 52 by the blowing air to pass through the flue of the water tank 53. And, the pellet material is dropped into the lower ash container 55, the smoke and unburned gas is heat-exchanged with the heating tube 58 through the flue 56 and the auxiliary flue 57, the smoke is light weight specific Emissions will occur.

In the above process, when the heating pipe 58 installed outside the flue gas induction pipe 54 and the flue 56 is heated by heat exchange, the water passing through the heating pipe 58 is warmed up, and thus the heating water 58 may be heated or heated. It becomes usable.

Moreover, the water heated in the water tank 53 in the upper part of the combustion chamber 52 can also be used for temporary use, such as for heating, a bathroom, and washing | cleaning.

In the present invention as described above, the pellet combustor provided in the combustion chamber 52 of the pellet boiler 50 overlaps the conical container 1a in which the pellets are combusted in the cylindrical tube 1 such that the air holding space H is provided. It is easy to manufacture the pellet combustor by welding and integrally constituting the cylindrical inlet (1) in the air inlet (2), the center of the ignition heater receiving tube (2a) connected to the conical container (1a) integrally. It is easy to install in the pellet boiler, it is possible to efficiently perform the ignition and combustion of the pellet in the combustion chamber of the pellet boiler.
