Embodiment
For that can further appreciate that the invention, features and effects of the utility model, following embodiments are hereby enumerated, and coordinate
Attached drawing describes in detail as follows.
The natural gas smelting furnace of the utility model is explained in detail with reference to Fig. 1：A kind of natural gas smelting furnace, bag
Include melting furnace main body 1, the melting furnace main body 1 is equipped with feed inlet, discharge port and is connected with 2 air inlet of air heat exchanger
Air outlet, the air outlet of the air heat exchanger 2 are connected by communicating pipe 3 with sack cleaner 4, built in the communicating pipe 3
One air-introduced machine 5, the air outlet of the sack cleaner 4 connect an aluminum heat-dissipating pipe 6, and the aluminum heat-dissipating pipe 6 is placed in water tank 7
