Description

Detailed Description of the Invention The present invention burns liquid fuel in the first furnace to heat its hot water chamber, and heats and burns kitchen waste, shells, etc. put into the furnace to heat the hot water chamber of the first furnace. Heating is performed, and a part of the combustion flame of the liquid fuel in the first furnace is passed through a flame passage provided with a heating plate in the second furnace,
The other part of the combustion flame of the liquid fuel in the first furnace is brought into contact with the heating plate to heat the hot water chamber of the second furnace, which communicates with the hot water chamber of the first furnace, together with the combustion gas such as the kitchen waste and shells, and the combustion gas is heated. If the hot water chamber becomes overheated, the first thermostat is activated to stop the fuel supply to the oil burner, only air is blown, and the hot water is discharged to the outside through the exhaust pipe. When the temperature in the room rises, the second thermostat is activated to stop blowing air, and when the temperature in the hot water room falls, the second thermostat is activated again to start blowing air.
Furthermore, when the temperature inside the hot water chamber drops, the first thermostat is operated backwards to open the fuel valve of the oil burner, and the fuel is combusted in the oil burner and air is blown to raise the temperature inside the hot water chamber. Regarding automatic incinerators.

In Patent No. 933339 (Special Publication No. 53-8939), a non-combustible substance is dried, heated, ignited and combusted using an oil burner, the hot water chamber is heated with the heat, and the heating in the hot water chamber is disposed of in a non-combustible manner. This is done using the heat of combustion of the fuel in the burner and incineration of the materials, but as the combustion gas of the incombustible materials is discharged outside the furnace without being fully combusted, the occurrence of air pollution and other pollution cannot be avoided. Ta. Also,
Since the combustion gas inside the furnace is discharged outside the furnace while still retaining residual heat, there is a drawback that a considerable amount of liquid fuel is wasted in order to maintain the temperature of the hot water to a certain degree.

The present invention was invented to eliminate these drawbacks, and it eliminates unpleasant odors caused by incomplete combustion of kitchen waste, etc., and further improves the hot water effect by fully utilizing residual heat of combustion gas. The aim is to provide an incinerator that achieves maximum efficiency with a small energy source.

Other objects, configurations, functions, and effects of the present invention will be explained with reference to the drawings.

This is a cylindrical second furnace located at the rear of the first furnace. Reference numeral 11 denotes a hot water chamber provided in the second furnace, and 12 denotes a circulation pipe that communicates the hot water chamber 4 of the first furnace 1 with the hot water chamber 11 of the second furnace. They are connected by flange joints etc. so that they can be separated and connected. 14

The first thermostat 20, which only blows air by closing the fuel supply solenoid valve and cutting off the fuel supply to the oil burner 6, operates when the heating temperature of the hot water chamber 2 is high and opens the blower circuit of the oil burner 6. , when the temperature of the hot water chamber 2 falls, the oil burner 6 is turned on again.
The second thermostat is shown closing the blower circuit.

Reference numeral 2a denotes a lid for inputting incinerated materials such as kitchen waste provided in the incinerated material inlet 2; 21, 21 denotes a pipe connecting the hot water chamber 4 of the first furnace 1 and the hot water chamber 11 of the second furnace 10 at the lower part; 22; , 22 is an ash chamber provided below the hot water pipe 5 of the first furnace 1 at the lower bottom of the first furnace.
Note that the food waste does not have to be placed directly on the hot water pipe 5, but can be placed via a suitable roistle. 23 is a water supply pipe provided in the second furnace, and 24 is a hot water take-out pipe provided in the second furnace.

When the temperature of the hot water chamber 4 further decreases, the first thermostat 19 opens the fuel supply solenoid valve of the oil burner 6, ignites the oil burner 6 with the pilot flame, heats and burns the incinerated material in the furnace, and cools the hot water chamber 4. heating the hot water inside and guiding the flame inside the first furnace 1 into the second furnace 10,
At the same time as heating the hot water in the second furnace 10, a flame is brought into contact with the heating plate 13 in the second furnace 10 to cause secondary combustion, thereby eliminating foul odors, CO, and other pollution-causing substances in the combustion gas. and discharged from the chimney 16.

As a result of the experiment, the combustion heat exchange section and hot water chamber of the first and second furnaces were connected through the combustion gas passage and hot water passage, respectively, and the oil burner was ignited in the first furnace. The incomplete combustion gas of the liquid fuel and the odor gas from the heated combustion of the incinerated material are re-burned by the heating plate installed in the second furnace using the blowing pressure of the oil burner and the suction action of the chimney, and the bad odor caused by the incomplete combustion is removed. It was found that no pollutants or impurities were released into the atmosphere. In addition, the first and second thermostats are automatically operated to ignite and extinguish the liquid fuel, as well as to heat the hot water chamber, making it flame retardant even when the raw material is incinerated through automatic repeated heating using an oil burner. It is possible to qualitatively change the ash to make it more combustible and to cause complete combustion, and the ash can be reliably dropped into the ash chamber. In addition, even if superheated steam tries to accumulate in the hot water room, by connecting a steam release valve with a check valve to the hot water room, the pressure inside the hot water room can always be adjusted to a safe level, making it possible to save valuable liquid fuel. The effects are outstanding, including the ability to save money. In addition, the heating plate is heated by the flame passing through the flame passage of the second furnace and is stored at a high temperature. This has the effect of heating and burning the fuel intermittently and then discharging it into the exhaust pipe.
