Description

[Detailed description of the invention] This invention relates to a device for supplying hot water to indoor heating and other equipment that requires hot water, and the fuel is not only ordinary wood chips, paper scraps, coal, etc., but also rubber fuel such as old tires. To provide a useful hot water supply device which completely burns water even if it occurs and is less likely to be discharged even if solid content is contained in hot air or flames.

To explain an example of implementation with reference to the drawings, the combustion chamber 1 and the heat exchange chamber 2 are arranged in parallel on a pedestal 11,
The upper part is communicated with a duct 3 so that the hot air and flame in the combustion chamber 1 can be sent to the heat exchange chamber 2, and a water storage chamber 4 is provided around the outer periphery of the combustion chamber 1, and a water storage chamber 4 is installed horizontally at the bottom of the water storage chamber. A plurality of water pipes are passed through the lower part of the combustion chamber 1 to constitute a water-cooled rostre 12, and the upper and lower parts of the water storage chamber 4 are provided with mounting ports 6, 6 for hot water circulation pipes (not shown). In the combustion chamber 1, a narrow roosttle 13 is attached below the water-cooled roostle 12, and is configured to receive ash, burning fuel, and the like. A water storage chamber 5 is also provided on the outer periphery of the heat exchange chamber 2.
The water storage chamber is provided with installation ports 7 and 7 for hot water circulation pipes (not shown) at the upper and lower parts of the water storage chamber, and the water storage chamber 5 is communicated with the water storage chamber 4 through an upper hot water duct 14 and a lower hot water duct 15. It is configured to circulate hot water while heating it. The air supply pipes 8, 8... are arranged at appropriate positions such as along the peripheral wall and in the center of the combustion chamber 1.
A large number of air supply holes 801, 801... are opened at positions facing the inside, and one end is connected to the blower 17 through the air distribution chamber 16.
The combustion chamber 1 is connected to the combustion chamber 1 so that air can be supplied into the combustion chamber 1 to achieve complete combustion. In addition to the illustrated example in which the air supply pipes 8, 8... are arranged in the combustion chamber 1, they are also arranged vertically in the water storage chamber 4 and communicated with the combustion chamber 1 through a communication pipe (not shown).
One end is connected to the blower 17 via the air distribution chamber 16, and air can be supplied into the combustion chamber 1 to achieve complete combustion. The air supply pipe 9 is piped from the air distribution chamber 16 to the lower side of the rostrum 13 in the combustion chamber 1, and blows up the incompletely burned fuel falling onto the rostrum 13 with air supplied from the blower 17 to complete combustion. I will try to achieve this. After checking the deposits on the rostol 13, the air supply is temporarily stopped and the ash is discharged. Smoke tube 1 installed in heat exchange room 2
0 is configured such that the water tank 18 formed on the heat exchange chamber 2 is penetrated, the smoke exhaust port 1002 is extended upward, and the smoke can be forcibly discharged by the exhaust fan 19, and the suction port 1001 is located at a position lower than the duct 3. The duct is arranged so that solid matter such as burning fuel and clumps of ash mixed with the hot air and flames sent through the duct are not immediately sucked into the smoke tube 10 and are separated from the hot air and flames. It is constructed so that it can fall to the bottom of the smoke tube 10, thereby reducing the risk of medium, ash lumps, fuel slag, etc. being discharged from the smoke tube 10.

In the figure, reference numeral 20 is a pressure regulating valve formed in the combustion chamber 1, and when the combustion pressure increases abnormally, the lid opens and hot air or flame is discharged to regulate the combustion pressure. code 2
1 is a water supply pipe arranged between the water storage chamber 4 and the water tank 18, and 22 is a water supply pipe formed in the water tank 18. Further, reference numeral 23 is a fuel supply pipe when waste oil is used as fuel, and it is piped to the upper part of the combustion chamber 1, and has a number of injection holes on the lower surface, and sprays toward the lower part of the combustion chamber 1, resulting in complete combustion. I'll force you to do it.

As mentioned above, this invention has an air supply pipe that supplies air to the combustion chamber from below the rostre, which blows up unburned fuel, incompletely burned fuel, etc. that falls on the rostrum, and causes flames to flow upward. Since we have installed an air supply pipe that supplies air to the combustion chamber from above the rostrum, no matter what the fuel is, such as wood chips, paper scraps, coal, old tires, etc.,
There are effects such as being able to supply a sufficient amount of air necessary for combustion into the combustion chamber and achieving complete combustion. In addition, because the inlet of the smoke tube provided in the heat exchange chamber is placed lower than the duct, solid matter is mixed in with the hot air and flames that are sent from the combustion chamber through the duct to the heat exchange chamber. Even if the solids are sucked in directly, the risk of them being ejected is reduced, and the solids are separated from the hot air, flames, etc., and fall to the bottom while burning and become ash. be.

Therefore, by complete combustion, hot water can be obtained with high thermal efficiency, fuel consumption can be reduced, and the exhaust gas can be cleaned.

Therefore, the intended purpose can be achieved.
