Description

[Detailed Description of the Invention] The present invention relates to an energy-saving water heater used in public baths and the like.

Conventional hot water boilers are wood-fired, which use only firewood as fuel, and oil-fired, which use only fuel such as heavy oil or kerosene, each equipped with a dedicated furnace for each type of fuel.

Therefore, it is inconvenient that wood boilers cannot use oil, and oil boilers cannot burn wood, so it is difficult to save fuel by burning wood and oil alternately or at the same time. could not.

This invention integrates a firewood furnace equipped with a castor rosdle and an oil furnace equipped with refractory bricks, and each is equipped with a firewood burning port and an oil burner installation port.
It can be used as both wood-fired and oil-fired, or it can be used as both wood-fired and oil-fired at the same time.According to this invention, it is possible to burn waste construction materials, old wood, combustible waste, etc., and it burns with moisture. It is convenient to heat and dry hard-to-burn wood etc. with an oil burner to make it easier to burn, and it is possible to provide a hot water boiler that reduces oil consumption and has good thermal efficiency.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a boiler, and 2 and 3 are wood burning ports and oil burner installation ports that are arranged side by side at the bottom of the front wall of the boiler.

A is a furnace, and this furnace A is formed by integrally forming a firewood furnace A□ and an oil furnace A2, which are arranged side by side.

The firewood burning port 2 and the oil burner mounting port 3 are provided corresponding to the respective furnaces A□ and A2.

In the firewood furnace A Arrange in a shape.

Reference numeral 7 denotes a flue that connects to the furnace A and traverses the inside of the boiler 1 from the back of the furnace A to the rear of the boiler 1.
A backfire vent 68 is provided in the flue 7 at the inner rear, and several flue pipes 10 with their rear ends open to the flue 7 are mounted horizontally on the front wall inside the boiler, and several exhaust pipes are installed above these flue pipes. The front end of the horizontal frame 11 opens into the connection chamber 9 in the same way as the smoke pipe 10, and the rear end opens into the rear wall of the boiler 1 and connects to the flue 12.

A water chamber 13 is formed inside the boiler 1.

14 is an oil tank attached to the outer circumference of the side wall of boiler 1;
15 is an electrode rod insertion hole drilled in the upper wall of the tank, 16 is a liquid level gauge provided on the front wall of boiler 1, 17 is a thermometer,
Reference numeral 18 indicates a water inlet provided on the upper wall of the boiler 1, and reference numeral 19 indicates an ash removal outlet.

In a water heater with such a configuration, firewood is put into the furnace A1 from the firewood burning port 2 and burned, or an oil burner is installed in the oil burner attachment port 3 and oil is burned in the furnace, or both of these methods are performed simultaneously. , the smoke is discharged through the flue 7, smoke pipe 10, connection chamber 9, exhaust pipe 11, and flue 12, and at the same time, these parts are heated or their temperature increases, so the water chamber 13 formed around them The water inside is heated and becomes hot water.

Since the present invention is configured as described above, firewood and oil burner can be inserted and attached to the firewood burning port 2 and oil burner installation port 3 respectively, and firewood and oil can be burned separately, or firewood and oil can be burned at the same time. It can be burned to heat the water in the boiler with high-calorie heat, waste wood and old wood can be used for firewood to save fuel, and oil can be used as fuel only when needed. It is enough to supply it.

Also, the furnace A, the flue 7, the next flue 10, and the exhaust pipe 1
The temperature of water in the water chamber 13 decreases in this order due to heat exchange with the water in the water chamber 13. Therefore, the temperature of the water in the water chamber 13 decreases around the exhaust pipe 11, around the smoke pipe 10, and in the water chamber. Water chamber 13 because the temperature gets higher around the bottom of water chamber 13 and toward the bottom.
By effectively utilizing the convection of water within the tank, it is possible to perform effective heat exchange and equalize the temperature of the hot water.

Furthermore, regarding maintenance, the cost furnace A1 and the oil furnace A2 are integrated side by side, and there is no complicated partition wall inside the furnace A, and the flue 10 and exhaust pipe 1
1 is opened and connected to a connecting chamber 9 which can be opened and closed, so it can be easily cleaned, and water leakage can be easily repaired because the ice chamber has a simple structure.

The present invention can effectively use a variety of fuels, save oil and boil bath water economically, and has a simple structure that makes it easy to handle and maintain. It is possible.
