Gas fireplace combustion device structure
View Patent ↗A gas fireplace combustion device structure includes a simulated solid fuel and a combustor under the simulated solid fuel. The combustor has a fire exit hole facing the simulated solid fuel, a combustion air inlet passage under the combustor, and a specific slot at the combustor to define a third combustion air inlet. A partition is installed under the combustor; a second combustion air inlet leading to fire exit hole is formed between the partition and the combustor; the combustion air inlet passage is provided for supplying air to the second and third combustion air inlets; a combustion air slot is formed at the middle of the simulated solid fuel to resupply combustion air to the flame above the simulated solid fuel in order to achieve a two-time sectional combustion. This invention can control and resupply combustion air to the flames in different areas to improve the combustion effect.
1. A gas fireplace combustion device structure, comprising;
a combustor; and
a simulated solid fuel,
wherein the combustor is installed under the simulated solid fuel, and a fire exit hole is formed on the combustor and configured to face at least one side of the periphery of the simulated solid fuel, and a combustion air inlet passage is disposed under the combustor, and
wherein the combustor has a slot formed at the middle thereof to form a combustion air inlet, and the combustion air inlet passage communicates to the combustion air inlet, and the simulated solid fuel has a combustion air slot formed thereon, and the combustion air slot and the combustion air inlet communicate with each other directly.
2. The gas fireplace combustion device structure of claim 1 , wherein the combustor has a partition disposed thereunder, and a further combustion air inlet leading to the fire exit hole is formed between the partition and a lower surface of the combustor lower surface, and the further combustion air inlet and the combustion air inlet passage communicate with each other.
3. The gas fireplace combustion device structure of claim 1 , wherein the combustion air slot is an irregular shaped strip slot, or one or more small holes, or a combination of the irregular shaped strip slot and the small holes.
4. The gas fireplace combustion device structure of claim 3 , wherein the quantity of the combustion air slot is one, two, or more.
5. The gas fireplace combustion device structure of claim 1 , wherein the simulated solid fuel is formed by combining two or more pieces.
6. The gas fireplace combustion device structure of claim 5 , wherein the combustion air slot is a slit or a gap between two or more simulated solid fuels.
7. The gas fireplace combustion device structure according to claim 1 , wherein the combustion air slot has an average width of 1 mm˜25 mm.
8. The gas fireplace combustion device structure claim 1 , wherein the combustion air inlet is a grooved opening having an average width of 2 mm˜30 mm.
