Description

The subject of the present invention is a heating gas stove with a lid for protection against gas explosion.

FIG. I schematically shows a furnace in vertical section with the lid closed; in fig. 2- oven in the same section when the burner ignites; in fig. 3-view oven in horizontal section along / - /.

The furnace is a chamber /, in the bottom, of which there is a gas burner. A gas burner 2 is installed above the burner. The chamotte 3, which plays the role of the furnace volume and the combustion catalyst, is attached to the bottom. The flue gases from the chamber / exhaust into the chimney through the pipe 4.

The gas furnace of the above design is uniformly heated so that it has maximum heat transfer for a given surface of the furnace.

To prevent an explosion of a furnace filled with a combustible mixture, when the furnace is kindled in the ceiling of the latter, a hole 5 is closed by a lid 6. For a small furnace, instead of 5, the entire furnace overlap is removable.

A firing tube 7 is inserted into the chamber through the opening 5, the lower end of which covers one or a group of openings of the gas burner. The gas / gas mixture jet, entering the firing tube 7, emerges from the opening of its upper end and is ignited here.

Due to the fact that the burning rate of the combustible mixture is much higher than the speed of the dwilseepi eschar of the combustible mixture in the ignition tube, the combustion of the mixture penetrates into the ignition tube 7 and, spreading against the movement of the combustible mixture, reaches the gas burner 2 and ignites it. As the chamber / pepp at the top is open, a light gas mixture floats up, air penetrates into the chamber and the gas mixture is diluted with air, thereby reducing the concentration of the gas mixture and it loses its ability to explode. An explosion cannot also occur due to the absence of an enclosed space filled with combustible gas.

When the burner is lit, the hole 5 is closed by the cover 6. The burner continues to burn, but the chamber is almost full of non-combustible

mixture, and combustion products, safe. in relation to the explosion.

In the event of a burner damping, the gas continues to be sucked off by the chimney, which in this case begins to play the role of a vent pipe.

Subject invention

It is a gas stove that represents the whole chamber, at the bottom

which is placed a gas burner, characterized in that a chamber is made in the chamber flawless opening, closed by a lid and intended to lower the firing tube and to prevent an explosion by opening the hole when the burner is ignited and the conveying gas is released from the chamber.
