Energy-saving and environment-friendly coal-fired cooking heating stove, cooking heating method and application

Abstract

The invention provides an energy-saving and environment-friendly coal-fired cooking heating stove, a cooking heating method and application. The coal-fired cooking heating stove is characterized in that a volatile component return pipeline is longitudinally arranged in a pyrolysis gasification zone, the top of the volatile component return pipeline is higher than a coal adding opening, and the bottom of the volatile component return pipeline extends into a semi-coke combustion area; a heating flue and a cooking flue are combined into a heating and cooking flue, and a cooking-heating switching rod and a movable cover plate are used to regulate the operation state of the coal-fired cooking heating stove. The coal-fired cooking heating stove has the advantages that on the basis of the staged combustion theory, the volatile component return pipeline is arranged in the pyrolysis gasification zone, and accordingly smoke reversing when the coal adding opening is opened can be avoided; in addition, the heating flue and the cooking flue are combined into one flue, the flue is provided with tertiary air orifice to form a secondary complete combustion area, flue gas complete combustion degree is enhanced greatly, and stable smoke-free combustion under full work conditions (coal adding, slagging, cooking, heating, stove sealing and the like) is achieved.

Description

technical field

[0001] The invention belongs to the field of coal-fired combustion equipment, and relates to a coal-fired cooking and heating furnace, a cooking and heating method and its use, and in particular to an energy-saving and environment-friendly coal-fired cooking and heating furnace, a cooking and heating method and its use based on the hierarchical combustion theory. Background technique

[0002] At present, households in some areas in northern my country, especially townships and rural households, generally use earth heating for heating. Due to the unscientific design of stoves, some coal cannot be completely burned and is discharged with smoke. The utilization rate is low. Not only the coal consumption is large, And it will cause serious air pollution. Moreover, in real life, while the majority of rural users are heating, they also hope that the stove can be used for cooking at the same time, such as boiling water, cooking and cooking.

[0003] At present, ther...
