Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used for boilers, water heaters, etc. that have a flat flame burner for the purpose of making the heater body lighter, thinner, and smaller by significantly reducing the internal pressure of the combustion chamber and furnace. This relates to Saharu heaters.

A burner such as a conventional boiler emits a long flame (for example, about 30σ or more) with a circular cross section. As a result, the boiler body becomes bulky and large, requiring a large space to install the boiler, etc., and it is extremely difficult to reduce the pressure inside the furnace as well as in the combustion chamber. A burner (referred to as a flat flame burner in the present invention) that emits a flame with a flame length of several centimeters or more Fahrenheit from the burner end by using AIJ for the burner of the heater used is made of ceramics or the like. ), and by using the flat flame burner, an extremely light, thin and small structure is achieved.The first invention includes a flat flame burner and a flat flame burner that covers the flat flame burner. A low-height combustion chamber is provided in the vertical direction, and a flat flame burner is placed horizontally at the bottom of the combustion chamber, and connected to the combustion chamber with a return chamber from the front end or rear end of the combustion chamber. The second aspect of the present invention is a heater equipped with a flat flame burner having a smoke pipe arranged therein. This heater is equipped with a flat flame burner, in which a flat flame burner is vertically disposed in front of a combustion chamber, and a group of water tubes are disposed next to the combustion chamber.

The present invention reduces the heat load of the combustion chamber to 10 to 20 million Kca by using a flat flame burner for the boiler melt.
1/m3hr or more, the combustion chamber can be made extremely small, and by devising the configuration of the heat transfer surface accordingly, there is the advantage that it can be made into a lightweight, thin, short, and small high-performance heater. Next, the present invention will be explained with reference to FIG. Burner (
The flame generated from 2) is completely combusted in a high-angle condition in the low-height combustion chamber +31, enters the return combustion chamber (4) from the front of the boiler, and from there passes through the combustion chamber (5) for heat exchange.

In addition, in Fig. 1, it is effective to set the slope of the earthen plate (1) in the combustion chamber (3) upward in the direction of the return combustion chamber (4) when installing it.

When the group is placed next to the combustion chamber (3) (7), the return combustion chamber (4) is placed closer to the rear end of the combustion chamber (3), and the smoke blowing part (5) is located next to the combustion chamber (7). It may be placed on the left, right, above, or below 3), and consideration should be given to whether the reheating chamber (4) should be placed closer to the front end or the rear end.

As shown in the above embodiments, the present invention allows the combustion chamber to be extremely small and the pressure inside the furnace to be extremely low. Therefore, the source pressure for fuel supply and supply can be made small, so that the requirements for θ are widened. /(-It has the advantage that it has a simple structure and has no moving parts, and that the entire boiler equipped with the heater having the flat flame burner of the present invention is small and can be made at low cost.
