Category or many metal composite pipes, including carbon steel, corrosion resistant metal outside, effectively raises the anti-corrosion of heating stove heat exchanger tube
Property, extend the service life of heat exchanger tube.
（2）The heating stove of the use composition metal heat exchanger tube that the utility model is provided, in exhaust gases passes（Fume collection case）
Heat-exchanging tube bundle is put in fork arrangement, is conducive to flue gas to form turbulent flow, and effectively heating surface area is utilized under less flue gas circulating resistance
Enhancing heat transfer effect, is greatly improved heating efficiency.
The heating stove of the composition metal heat exchanger tube that the utility model is provided, using composition metal heat exchanger tube and heat exchanger tube
Fork arrangement is put, and improves the corrosion resistance and heating efficiency of heat exchanger tube, significantly extends the service life of heating stove.
