Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the configuration of a boiler that can burn both a heat source such as an oil burner and a heat source such as solid fuel.

[Conventional technology]

Japanese Patent Application Laid-Open No. 53-133980 is known as this type of technology, but its feature is that it detects the water temperature and controls the fuel supply to the combustion chamber, and it uses air blowers to remove the fallen ash. A modified damper technology is disclosed.

[Problem that the invention attempts to solve]

The purpose of this invention is that when the temperature of the water tube inside the boiler body rises to a predetermined temperature, the thermoswitch operates to stop the oil burner in the first combustion chamber of the boiler body, and at the same time stop the combustion of solid fuel in the second combustion chamber. Then, water is supplied at a predetermined temperature, and when the temperature of the water tube inside the boiler falls, the thermoswitch is activated again to start combustion inside the boiler. At this time, although the technology for shutting off oil burners and the like is easy, there is no known automatic control for shutting off technology for solid fuels, etc., and this was devised as a result of intensive research on this point.

[Means for solving problems]

This invention has achieved the technical problems mentioned above,
A first combustion chamber 2 for a heat generation source 4 such as an oil burner is located at the bottom of a boiler body 1 which has water pipes 8 vertically and horizontally inside.
A second combustion chamber 12 for solid fuel and wood fuel is disposed in the upper part via a roaster 10, and an exhaust pipe 22 is connected to the second combustion chamber 12, and the outer periphery of the exhaust pipe 22 is A blow pipe 24 is formed on the wall, and the blow pipe 2
The present invention proposes a boiler characterized in that one end of the damper 26 is connected to a heat generating source 4 such as an oil burner, and the other end is equipped with a damper 26 that automatically controls the water pipe temperature to shut off air.

[Effect]

When the thermometer in the boiler body reaches a predetermined temperature, the combustion of the heat source such as the oil burner stops, the blower motor and damper of the blower pipe are shut off, and the second combustion chamber becomes oxygen deficient and combustion stops. Stop. At this time, the solid fuel remains as a pilot flame, so when the temperature of the hot water falls to a predetermined level, the thermometer is activated again, the blower motor and damper are activated, and combustion is started.

24 is an exhaust pipe, 26 is a damper of the air pipe 24, 28 is a magnet for the damper 26 of the air pipe 24, and 30 is a flange of the air pipe 24.

In FIG. 2, reference numeral 32 is a water supply port that supplies water to the water pipe 8 in the boiler body 1, 34 is a drain port,
36 is a hot water supply port provided at the top of the boiler body 1;
8 is a safety valve installation port, 40 is a thermometer of the boiler body 1, 42 is a kerosene thermometer, and 44 is a firewood thermometer.

In the circuit diagram in Figure 7, F is fuse, TH
is a thermo switch for firewood thermometer 44, M is a blower motor, S is a switch for firewood hopper 16,
TH ₁ is a thermoswitch for kerosene thermometer 42,
T indicates an ignition transformer, R indicates a delay relay, and P indicates an electromagnetic pump.

To explain the operating state of this device, water is supplied from the water inlet 32 of the boiler body 1 of this device to fill the boiler body 1 with a predetermined amount of water, and the combustion chamber 12 is filled with water.
The lid 14 of the combustion chamber 12 is opened and the required amount of solid fuel L made of solidified waste etc. is put into the combustion chamber 12. Next, when the heat generation source 4 such as an oil burner is ignited, the heat generation source burns the required amount of solid fuel L via the roaster 10. The combustion heat rises in the combustion chamber 12 and is exhausted to the outside air through the exhaust stack 22. At this time, the kerosene thermometer 42 of the boiler body 1 shuts off when the temperature reaches 50℃,
Also, if you set the boiler to operate when the temperature reaches 40℃, the temperature of the water pipe 8 of the boiler body 1 will be 50℃.
℃, the thermoswitch TH ₁ for the kerosene thermometer 42 is activated and the circuit shown in FIG.
operates, the damper 26 shuts off, the second combustion chamber 12 becomes oxygen-deficient, combustion stops, and the solid fuel L remains as a pilot flame. When the combustion inside the combustion chamber 12 decreases, the water pipe 8 of the boiler body 1 decreases.
The temperature of the water inside will drop. Particularly, when the temperature of the kerosene thermometer 42 reaches 40°C, the thermoswitch TH ₁ for the kerosene thermometer 42 is activated, and at the same time the blower motor M and the magnet 28 of the blower pipe 24 are turned on.
operates, the damper 26 of the blast pipe 24 also operates, the heat source 4 such as an oil burner operates, and the second combustion chamber 1 is activated.
Combustion within 2 begins.

Incidentally, the firewood hopper 15 is used when supplying fuel such as rice husk without using the solid fuel L, and in this case, the firewood thermometer 44 and the thermoswitch TH for the firewood thermometer 44 are used. It is preferable to set the shutoff temperature of the thermoswitch TH to 70°C and the operating temperature to 60°C.

〔effect〕

This invention is implemented as described above, and with a simple configuration, the temperature increase inside the boiler body 1 can be accurately determined by the thermometer 40, and the temperature inside the boiler body 1 can reach a predetermined temperature. When this occurs, the thermoswitch TH ₁ for the kerosene thermometer 42 or the thermoswitch TH for the firewood thermometer 44 is activated immediately to stop combustion in the boiler body 1, thereby contributing to energy conservation. Furthermore, the magnet 28 for the damper 26 of the blow pipe 24 and the blow pipe 24 are activated by the operation of the thermoswitches TH ₁ and TH.
The damper 26 works smoothly to cut off the air and create an oxygen-deficient condition, so solid fuel, etc. does not burn unnecessarily and waste, and the preheating of the exhaust stack is used during combustion to blow air. Therefore, there are practical benefits such as improved thermal efficiency.
