Description

High-efficient natural gas drying and heating furnace

Technical Field

The utility model relates to a metallurgical industry technical field, in particular to high-efficient natural gas drying and heating stove.

Background

Furnaces are equipment that we often see in factories. The working principle of the heating furnace is as follows: the high-temperature flame and the flue gas generated when the fuel is combusted in the hearth are used as heat sources to heat the medium flowing in the furnace tube to reach the specified process temperature.

The fuel is sprayed out from the burner to burn to generate high-temperature flame and high-temperature flue gas, and the high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, so as to transfer the heat to a medium in the furnace tube. The high-temperature flue gas upwards enters a convection chamber of the heating furnace under the action of the draft force of a chimney or a draught fan, and heat is transferred to a furnace tube in the convection chamber in a convection mode so as to be transferred to a medium in the furnace tube.
