Multifunctional furnace with backflow dual combustion-chamber device

Abstract

The invention provides a multifunctional furnace with a backflow dual combustion-chamber device, belonging to a household living furnace which has simple structure and can completely combust fuels. A partition plate is arranged in the furnace, an upper fire opening is arranged at the rear part of the partition plate, and an adjusting plate is arranged in a smoke outlet. Flames flow back from the upper fire opening, flow to an upper combustion chamber from a lower combustion chamber, and flow to a chimney from the upper part of the smoke outlet after passing through the upper combustion chamber and the lower combustion chamber, so as to realize adjustable fire power. The semi-gasification multifunctional furnace has the following characteristics: a furnace mouth does not discharge smoke tothe indoor part, smokeless baking can be carried out, the effects of energy saving and emission reducing are obvious, the manufacturing is easy, and the cost is low.

Description

1. Technical field [0001] The present invention relates to a multipurpose furnace for domestic or similar occasions. 2. Background technology [0002] No matter what kind of stove, to make the fuel burn completely and fully in the stove, three conditions must be met, one is sufficient combustion temperature, the other is enough air and its uniform mixing with the fuel, and the third is enough Combustion time or space, the three are indispensable, only when the fuel is fully burned, can the heat contained in it be released. However, due to structural limitations, it is difficult for domestic furnaces to meet these conditions at the same time. The Chinese patent No. 90205721.9 realizes that the end pot does not emit smoke, so that people's living room is free from smoke pollution, the combustion conditions in the furnace are improved, the furnace temperature is higher, and the flame spreads around, and the combustion area is reduced due to diffusion. Increase, make it diffic...

Problems solved by technology

However, due to structural limitations, it is difficult for household furnaces to meet these conditions at the same time.

Chinese patent No. 90205721.9 realizes that the end pot does not emit smoke, so that people's living room is free from smoke pollution, the combustion conditions in the furnace are improved, the furnace temperature is higher, and the flame spreads to the surroundings, and the combustion area is reduced due to the diffusion. The increase makes it difficult to mix the air and the flame, and the heat absorbing area of ​​the heat receiver is large, so that the peripheral temperature drops rapidly, making it difficult to maintain the normal state of combustion, resulting in insufficient fuel combustion, and the structure of the heat receiver is large , so that the structure of the furnace becomes larger, the cost rises, and the manufacture of the heat receiver is also more difficult
