る。The present invention was developed in an effort to eliminate these drawbacks, and the structure will be explained below with reference to the drawings. As shown in Figure 3.1, a fuel inlet 2, a sealing lid 3, In addition, there is an ash collection port 4 in the lower part, as well as an opening/closing adjustment IN 5,
be crowned with. Fresh water 10 is contained inside the fire grate (rosdol) 6, the combustion chamber 7, the flame passage 8, the fire heat absorbing water wall 9, and the main body l. Also, cold water + around the outside of the chimney 11.
2, the outer plate 13 that includes 0, which is completely wrapped, and the chimney 1! ,
The cold water valve 14 injects cold water 12 into the upper end of the outer plate 18 of the water heater body 1, and then the lower end of the outer plate 18 wrapped around the chimney 11 communicates with the lower end of the water heater body l. Water pipe 15. Attach the freshwater 10. is injected from the lower part of the water heater main body l as shown by arrow B, and a discharge valve 16 is attached to the upper part.The embodiments of this invention will be described in detail with reference to the drawings.
As shown in the figure, cold water 12. , the cold water valve 14 provided on the outer plate 18 wrapped around the upper end of the chimney +1! cold water 12,
By injecting water into the water heater body 1. Fresh water 10 then overflows and fills the discharge valve 16. Next, fuel input port 2,
Open the crown 13 and drop fuel 17, i.e., wood chips, garbage, etc., onto the top of the grate (rosdol) 6.
The ignition fuel 18, which is easily combustible, such as paper waste, is ignited with something like a stick into the inside of the ignition fuel 18, and the fuel 17 is ignited. 21 in the process of immediate distribution of A! >The heat radiated by the lever absorbs the fire heat by the water wall 9, and the fresh water inside 10. is absorbed and becomes hot water. Also, the Mononoke cold water 12 shown in Figure 2. The cold water valve 14 provided at the top of the residual heat recovery tank 19 is opened, and the cold water 12 is opened.
By injecting residual heat recovery tank 19 and water pipe 2]
, fresh water is supplied to the water heater body 1 through 10. The fuel F+ is filled and discharged from the discharge valve 16.Then, the seal 8 of the fuel inlet 2 is opened, and the fuel F+ 17 is dropped into the upper part of the grate 6. 1g of flammable ignition fuel such as paper scraps
In the process of igniting the fuel 17 with something like a matchstick and burning the fuel 17, K ignites and burns and circulates through the flame passage 8, the heat radiated from it is absorbed by the fire heat absorbing water. The fresh water 10 inside the surrounding wall 9 absorbs the water and turns it into hot water.This hot water is then sent to a predetermined location through the discharge valve 16. However, in this case, a certain amount of heat is transferred to this hot water. In order to recover residual heat flowing out of the chimney 11 and K, a residual heat recovery tank 19 is filled with a residual heat recovery water wall 20 and fresh water 10, and an exhaust passage 22 is formed as shown by arrow C1. Complete exhaust heat, ie residual heat, can be recovered by exposing the exhaust gas for as long as possible. As a result, only a small amount of fuel is required, and water can be boiled in a short time, which is extremely economical.
