Problems solved by technology

In actual use, the burner 7' is set on one side of the airtight container 9' for high-temperature heating. Because of its setting problem, the heating area of ​​the burner 7' is limited, especially in the initial heating process, resulting in the airtight container 9' The temperature of the part in contact with the high-temperature heat source is not uniform, and the temperature rise rate is slow in the initial process, which affects the effect of heat treatment, so that the effect of metal heat treatment is not good

Abstract

An industrial furnace capable of achieving rapid temperature rise comprises a furnace body (1), a furnace door (2), a flue (3), a smoke outlet (4), a shell (5), a combustion chamber (6), a combustor (7) and an air inlet (8) and further comprises a preheating tube (10). The preheating tube (10) comprises a horizontal channel (101) and a vertical channel (102). The horizontal channel (101) is arranged in the flue (3). A gas curtain (12) is formed by gas sprayed out of the outlet end of the vertical channel (102), and the air inlet (8) is covered with the gas curtain (12). The combustion chamber (6) further comprises a first combustion chamber body (62) and a second combustion chamber body (63). Side wall openings (631) allowing gas to flow are formed in the side wall (630) of the second combustion chamber body. The heating furnace is provided with the combustion chamber and the gas curtain, so that heating speed in the initial heating process is increased, and the overall structure is simple.

Description

technical field [0001] The invention relates to a heating furnace, in particular to an industrial furnace for rapid temperature rise directly using a burner as a heat source. Background technique [0002] As a commonly used industrial product, industrial furnaces have been widely used in many occasions, including electric furnaces, heating furnaces, biomass carbonization furnaces, etc. During use, sometimes it is necessary to heat treat some metal workpieces. In the prior art, the heating heat source can be electric heating, fuel heating or gas heating. Usually, the industrial furnace includes a furnace body 1', a burner 7' and a combustion chamber The air inlet 601', a closed container 9' with a heating space 90' ​​is arranged in the furnace body 1', and the object 91' to be processed is placed in the 90' ​​for heat treatment. In actual use, the burner 7' is set on one side of the airtight container 9' for high-temperature heating. Because of its setting problem, the heati...
