Abstract

The invention relates to a natural gas annealing furnace. The natural gas annealing furnace comprises an annealing furnace body, a fan and a preheating furnace. The annealing furnace body communicates with the preheating furnace. The front side and the rear side of the annealing furnace body are correspondingly provided with multiple natural gas burning guns. The front ends of the natural gas burning guns are located in the annealing furnace body. The tail ends of the natural gas burning guns are connected with a natural gas main pipeline through natural gas branch pipelines. The upper end in the preheating furnace is provided with a heat exchanger. The heat exchanger is provided with an air inlet pipe and an air outlet pipe which are located outside the preheating furnace. The air inlet pipe is connected with the fan. The air outlet pipe is connected with a combustion-supporting air main pipeline. The combustion-supporting air main pipeline is connected with multiple air inlet branch pipelines. The tail ends of the air inlet branch pipelines extend into the annealing furnace body. The natural gas annealing furnace is simple in structure, combustion-supporting air is preheated through annealing furnace waste gas energy and then is mixed with natural gas in to combustible gas, the production cost is lowered, and the energy utilization rate is increased.

Description

technical field [0001] The invention relates to a natural gas annealing furnace. Background technique [0002] In order to improve the mechanical properties of the material, it needs to be annealed during the processing of the material. The general structure is to pass the wire through the annealing chamber, heat it through the heater inside, and then cool it, so that the excess heat generated by the exhaust gas is dissipated. waste energy into the air. Contents of the invention [0003] In view of the above defects, the object of the present invention is to provide a natural gas annealing furnace with simple structure, which can be preheated by waste gas and improve energy utilization rate. [0004] The technical scheme that the present invention adopts for this reason is: [0005] It includes an annealing furnace, a fan and a preheating furnace. The annealing furnace communicates with the preheating furnace. A number of natural gas burners are respectively arranged on ...
