Household straw pellet downward guiding type combustion furnace

Abstract

The invention discloses a household straw pellet downward guiding type combustion furnace, and belongs to the technical field of straw pellet combustion equipment. The combustion furnace is mainly composed of a feeding device, an air inlet adjusting ring, an upper furnace body, a furnace grate and a lower furnace body. The feeding device is movably connected with the upper furnace body through a thread. The air inlet adjusting ring is arranged on the outer side of the upper furnace body with vent holes II in a sleeving manner. A supporting ring I of the upper furnace body is in contact with a supporting ring II of the lower furnace body. A combustion chamber is formed by the upper furnace body and the lower furnace body and is divided into two cavities by the furnace grate located on an annular platform of the lower furnace body. Vent holes I are formed in the lower portion of the feeding device. Vent holes are formed in the positions, below the furnace grate, of the side face and the bottom face of the lower furnace body. The combustion furnace has the beneficial effects of being simple in structure, convenient to manufacture and use and capable of enabling straw pellets to be fully combusted, and is especially suitable for straw pellet combustion of northern rural areas.

Description

technical field [0001] The invention relates to a down-drawing type combustion furnace for household straw granules, in particular to a down-drawing type straw granule combustion furnace for household use in northern rural areas, and belongs to the technical field of straw granule combustion equipment. Background technique [0002] Straw granule fuel is a kind of fuel formed by pressing crop straw through high temperature and high pressure with special equipment such as straw granulator. It has the advantages of high density, convenient transportation and storage, and its combustion performance has also been greatly improved. An important fuel for heating in winter. However, most of the existing combustion furnaces are traditional furnaces, which have poor ventilation and insufficient combustion of straw. On the one hand, resources are wasted, and on the other hand, due to insufficient combustion, a large amount of smoke and even harmful gases will be generated. People livi...

AI Technical Summary

Problems solved by technology

However, most of the existing combustion furnaces are traditional furnaces, which have poor ventilation and insufficient combustion of straw. On the one hand, resources are wasted, and on the other hand, due to insufficient combustion, a large amount of smoke and even harmful gases will be generated. People living in northern homes in state pose significant safety risk

At the same time, since the heat and flue gas of the down-drawing combustion furnace circulate from the bottom, if the ventilation is not smooth, it is very easy to cause the flue gas to flow back, and even cause problems such as open flame overflow
