Abstract
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.
