Embodiment 1

[0055] This embodiment provides a coal-fired hot air heating furnace and a heating method thereof, such as figure 2 As shown, the furnace top side of the coal-fired hot air heating furnace is provided with a chimney 1, the bottom of the chimney 1 inside the furnace body is provided with a first transverse partition 2, and one side of the first transverse partition 2 is connected to the furnace body. The furnace walls on one side of the chimney 1 are connected, and the other side of the first horizontal partition 2 is perpendicular to the first horizontal partition 2. The first vertical partition 3 is arranged, and the first vertical partition 3 divides the interior of the furnace body into two Connected chambers, the chamber located on one side of the chimney 1 is a pyrolysis gasification area, and the chamber on the other side is a flue gas burnout area; a grate 4 is arranged obliquely below the pyrolysis gasification area, and the A primary tuyere 5 is set under the furnace ...

Embodiment 2

[0065] This embodiment provides a coal-fired hot air heating furnace and a heating method thereof, such as Figure 4 As shown, the furnace top side of the coal-fired hot air heating furnace is provided with a chimney 1, the bottom of the chimney 1 inside the furnace body is provided with a first transverse partition 2, and one side of the first transverse partition 2 is connected to the furnace body. The furnace walls on one side of the chimney 1 are connected, and the other side of the first horizontal partition 2 is perpendicular to the first horizontal partition 2. The first vertical partition 3 is arranged, and the first vertical partition 3 divides the interior of the furnace body into two Connected chambers, the chamber located on one side of the chimney 1 is a pyrolysis gasification area, and the chamber on the other side is a flue gas burnout area; a grate 4 is arranged obliquely below the pyrolysis gasification area, and the A primary tuyere 5 is set under the furnace...

Embodiment 3

[0077] This embodiment provides a coal-fired hot-air heating furnace and its heating method. The structure of the coal-fired hot-air heating furnace refers to the structure of the coal-fired hot-air heating furnace in Example 2. The difference lies in: the number of the tertiary air outlets 13 for 2 pcs.

[0078] The heating method refers to the method in Example 2, the difference is that the coal used is clean briquette prepared from bituminous coal containing a soot-fixing agent, a sulfur-fixing agent and a denitrification agent.

[0079] In this embodiment, the combustion temperature of the semi-coke combustion zone described in step (b) is 900°C; the volumetric heat load of the semi-coke combustion zone is 330kW / m 3 , the area heat load is 2.5kW / m 2 The temperature of the flue gas burnout in the flue gas burnout zone in step (c) is 800° C.; the thermal efficiency of the cooking hot air heating stove is about 80%.

Abstract

The invention provides an energy-saving and environment-friendly coal-fired hot-blast heating stove and a heating method and application thereof. The coal-fired hot-blast heating stove is characterized in that a chimney is arranged on one side of the top of the stove body of the coal-fired hot-blast heating stove, a heat exchanging device is arranged in the chimney, an air distribution device is arranged outside the chimney, the heat exchanging device comprises a tube side and a shell layer, the tube side is communicated with flue gas circulating in the chimney, and the shell layer is communicated with the air distribution device. The coal-fired hot-blast heating stove has the advantages that the heat exchanging device is arranged in the chimney of the coal-fired hot-blast heating stove, and heat in the flue gas is recycled to heat indoor air; an air sleeve wraps the stove body of the coal-fired hot-blast heating stove and can effectively control the temperature of a semi-coke combustion area and a flue gas complete combustion area, the heated air can be used for indoor heating, and indoor air heating circulation utilization is achieved.

Description

technical field [0001] The invention belongs to the field of coal-fired combustion equipment, and relates to a coal-fired hot air heating furnace and its heating method and application, in particular to an energy-saving and environment-friendly coal-fired hot air heating furnace and its heating method and application. 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, there are two main types of coal-fired stoves on the market: [0...
