Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, specifically to an internal pipe-supply air gasification furnace. Background Technology

[0002] A gasifier is a type of combustion furnace. With technological advancements, gasifiers are becoming increasingly widely used, including portable outdoor applications. Portable gasifiers are typically small in size, simple in structure, and very easy to carry. The main body of a gasifier generally consists of an outer shell and an inner liner. The space between the inner liner and the outer shell serves as a ventilation duct to provide oxygen for fuel combustion. Fuel is added to the furnace from the top and is located in the middle of the inner side of the inner liner. Because the inner liner surrounds the furnace, the ash after combustion is difficult to clean and requires complete tipping and emptying. Moreover, a large amount of ash remains when emptying the ash, requiring repeated tipping and emptying to clean it thoroughly. Furthermore, because portable gasifiers have a simple structure, the burner outlet at the top is in direct contact with the bottom of the pot, making the support structure very unstable and prone to tipping over.

[0003] Therefore, the inventors aimed to solve the problem of designing a gasifier with internal duct air supply, material-saving features, a side-opening door for easy ash cleaning, and multiple support methods. Utility Model Content
