Description

Special burner for acetylene gas of roasting furnace

Technical Field

The utility model belongs to the technical field of the technique of burning furnace over a slow fire and specifically relates to a special nozzle of burning furnace carbide gas over a slow fire.

Background

Acetylene, which is also acetylene, generates high temperature when it is burned, and is mainly used for cutting, welding metals, drying, heating materials, etc. When the roasting furnace is used, the tourmaline is mainly combusted through a burner or a burner to provide heat for the roasting furnace. However, in the existing industry, the burners or burners need matching air supply and air regulation systems regardless of forced air supply or natural ventilation. The use of the air supply and air regulation system has no problem on common heating equipment, but on some special heating equipment, such as: the hammer type drying crusher, the vertical roasting furnace and other special roasting furnaces cannot be used. Because this type of furnace requires heating of the vertically rising air, which is heated to the desired temperature and then used directly to dry or heat the material in the furnace chamber, this requires that burners or burners must be mounted directly on the equipment to heat the rising air vertically using the heat generated by the combustion of the gas. Because the mounting position (flame spraying direction) of the burner is vertical to the rising air, a large amount of low-temperature air which rises vertically easily blows out the flame, the irregularity of combustion is interrupted, and the trouble is brought to production. Furthermore, because the structure of the roasting furnace is limited, a large air supply and air regulation system is not provided, so that the traditional burner cannot be used, and because the temperature of air supplied by the air supply and air regulation system is relatively low (relative to the temperature of air in the hearth), more energy is consumed for heating the air, and a large amount of energy resources are wasted.
