Coal and wood dual purpose furnace for cooking and warming

Abstract

The invention discloses a coal and wood dual purpose furnace for cooking and warming. The dual purpose furnace comprises a furnace body, a charging device, a fire grate, a furnace door and a cooking range, wherein the furnace body is provided with a fuel chamber and a combustion chamber, the fuel chamber is communicated with the combustion chamber, the fuel chamber is arranged above one side of the combustion chamber, the cooking range is arranged above the other side of the combustion chamber, the charging device is arranged on the furnace body and at the top of the fuel chamber, the fire grate is arranged in the combustion chamber, the lower part of the bottom of the fuel chamber is provided with a primary tuyere, and the upside of the fire grate is provided with a secondary tuyere. Thefuel chamber is arranged above one side of the combustion chamber and the cooking range is arranged above the other side of the combustion chamber so that the combustion chamber can not only heat thecooking range, but also perform dry distillation to the fuel in the fuel chamber, the volatile generated by the dry distillation of the fuel in the fuel chamber is mixed with the secondary air to burn in the combustion chamber while the fuel becomes loose after the dry distillation and carbonization so that the fuel is easy to drop into the combustion chamber to burn, the ash is discharged from the fire grate, and the combustion is extremely sufficient without black smoke.

Description

technical field

[0001] The invention relates to a stove, in particular to a dual-purpose heating stove with coal and firewood. Background technique

[0002] At present, there are still certain difficulties and great waste in completely using firewood for cooking and heating. This is because compared with coal, firewood has the characteristics of large volume, light weight, loose structure, high volatile content and short precipitation time. . The structure of traditional firewood stoves generally adopts the normal combustion method, that is, firewood is added from the top, ignited below the hearth, air is taken in from the bottom of the grate, and firewood is burned from bottom to top. In order to make the combustion uninterrupted, fuel must be added frequently, which increases the labor intensity. Oxygen deficiency is very easy on the oxide layer of the normal combustion method. Again because of the need to constantly open the furnace door to add firewood frequently, col...
