Embodiment Construction

[0009] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0010] Such as figure 1 A coal-fired hot blast stove as shown comprises a furnace body 1, a heat exchange device is arranged in the furnace chamber of the furnace body 1, the lower part of the furnace body 1 is a combustion chamber 2, and the exhaust gas outlet 1-1 in the middle of the furnace body 1 is connected with a The flue gas dust collector 3, the side wall of the combustion chamber 2 is provided with a hot air outlet 2-1, and the top of the furnace body 1 is also provided with a secondary air inlet 1-2, which can make the intake air sufficient and the combustion complete.

[0011] In order to increase the air volume, a blower 4 is connected to the sec...

Abstract

The invention relates to hot-air central heating equipment, particularly to a coal-fired hot-blast stove. The coal-fired hot-blast stove comprises a stove body, wherein a heat-exchanging device is arranged in the furnace chamber of the stove body; a combustion chamber is arranged at the lower part of the stove body; a smoke dust catcher is connected with a tail gas outlet at the middle part of the stove body; a hot-air outlet is arranged on the side wall of the combustion chamber; and a secondary air inlet is further arranged at the top of the stove body. As the secondary air inlet is arranged at the top of the stove body, the coal-fired hot-blast stove in the invention achieves sufficient air feed and full combustion, solves the problem of flue waste caused by insufficient combustion fundamentally and reduces the cost. Furthermore, the hot-air central heating equipment has the characteristics of compact structure, reasonable layout, large heat-exchanging strength, fast temperature rise speed, high heat efficiency, small occupied area, convenience for installation and operation, clean air hot, stable properties and the like.

Description

technical field [0001] The invention relates to a hot air centralized heating equipment, in particular to a coal-fired hot blast stove. Background technique [0002] Hot air stove is widely used in drying, spraying and dehydration of various materials such as chemical industry, food, medicinal materials, tobacco, ceramics and building materials. It can also be used for heating of buildings such as workshops, auditoriums, farm sheds, and livestock houses, as well as dehumidification or heating of underground mining areas and underground engineering. Most of the existing hot blast stoves only have one air inlet, which will cause insufficient fuel combustion in the furnace body, resulting in waste of resources and increased costs. Contents of the invention [0003] In order to fully burn the fuel, the present invention provides a coal-fired hot blast stove, which includes a furnace body, a heat exchange device is arranged in the furnace cavity of the furnace body, the lower ...
