Methane gas combustion device and methane gas fireplace

Abstract

The invention relates to a methane gas combustion device and a methane gas fireplace. The methane gas combustion device comprises a combustor and a guide device. The combustor is provided with a methane gas outlet; the guide device is combined with the combustor and comprises a partition and two baffles; the partition is provided with an opening; the baffles are located at the opening; the top edges of the baffles are higher than the upper surface of the partition; the combustor is located below the partition; the methane gas outlet is located in a position corresponds to a position between the two baffles; the guide device is further provided with at least one first gas inlet; the first gas inlets are located below the partition and communicated with a space between the two baffles. The methane gas fireplace comprises a fireplace body, a light-transmission shield and the methane gas combustion device. The partition divides the fireplace body into a gas chamber and a combustion chamber, and the combustor is located in the gas chamber. Therefore, the flame visibility and the combustion efficiency are improved.

Description

technical field [0001] The present invention relates to gas burning equipment; in particular, it refers to a high-efficiency decorative flame gas burning device and a gas fireplace. Background technique [0002] The existing DIRECT-VENTED gas fireplace adopts a natural balanced intake and exhaust method. The exhaust port and the intake port are connected to the combustion chamber in a vertical or horizontal direction, and are connected to the outside. The air in the room is completely isolated from the combustion chamber, so Direct row (DIRECT-VENTED) gas fireplace is currently the safest fireplace. Since both the exhaust port and the air intake port are connected to the outside, for the convenience of construction and installation, the exhaust pipe and the intake pipe usually adopt the design of pipe-in-pipe. As an exhaust pipe, the outer pipe is also connected to the air intake channel at the rear of the furnace body; the air intake channel can be connected to the outside...

Problems solved by technology

(3) Flame type and color: Since the fireplace must visually imitate wood burning and present a large proportion of orange flames to meet the aesthetic needs of decorative flames, colorless or blue flames cannot meet the visual needs of decorative flames

[0017] When applied to a gas fireplace, the turbulent flow generated in the airtight furnace body will strengthen the disturbance and convection of the internal airflow, especially when the scale of the flame is increased, the air with high oxygen concentration introduced from the outside is easily disturbed by the turbulent flow, so it is difficult to Control favorable combustion conditions

Therefore, the design of the existing gas combustion device 1 is still not perfect, and there is room for improvement.
