燃气热风炉的换热器就是把热流体部分热量能够传递给冷流体设备，因此在许多的行业生产当中具有的重要方位。燃气热风炉换热器的种类非常多，我们可以依据冷流体以及热流体的热量沟通原理还有方法基本上能够分为1.间壁式燃气热风炉换热器、2.混合式燃气热风炉换热器、3.蓄热式燃气热风炉换热器。但是对于换热器拆除检查是要定期进行的 ，但是在拆卸热风炉换热器检查时哪些问题需要注意呢？
The heat exchanger of gas-fired hot-blast stove can transfer part of heat of hot fluid to cold fluid equipment, so it has an important position in many industries. There are many kinds of heat exchangers in gas hot blast stove. According to the principle of heat communication between cold and hot fluids, we can basically divide them into 1. Interwall gas hot blast stove heat exchanger, 2. Mixed gas hot blast stove heat exchanger and 3. regenerative gas hot blast stove heat exchanger. But for the heat exchanger removal inspection is to be carried out regularly, but in the removal of hot blast stove heat exchanger inspection, what problems need attention? 
1、板式的燃气热风炉换热器在我们进行拆开之前，需要丈量板束压紧的长度尺度，然后做好记录，重装的时候需要按照此尺度选择零部件。
1. Before we disassemble the plate heat exchanger of gas hot blast stove, we need to measure the length scale of plate bundle compression, and then record it well. When we re-install, we need to select parts according to this scale.

2、需要查看密封垫片是不是粘在两板片间的沟槽内，如果在我们就需要使用螺丝刀小心肠将它分开，螺丝刀需要先从易剥开的地方插入，之后需要沿其周边实行别离，记住不可以损坏燃气热风炉换热器板片以及密封垫片。
2. We need to check whether the sealing gasket is stuck in the groove between the two plates. If we need to use a screwdriver carefully to separate it, the screwdriver needs to be inserted from the easy-to-peel place first, then we need to separate along its periphery, remember that we can not damage the heat exchanger plate and the sealing gasket of the gas hot blast stove.

3、更换密封垫片时，需要用丙酮或其他酮类有机溶剂，将密封垫片沟槽擦净。再用毛刷将合成树脂粘接剂均匀涂在沟槽里。
3. When replacing the sealing gasket, acetone or other ketone organic solvents should be used to wipe the grooves of the sealing gasket. Then the synthetic resin adhesive is evenly coated in the groove with a brush.

4、查看燃气热风炉换热器板片是否有穿孔，一般用5倍的放大镜，也可用灯光或煤油渗透法等逐片查看。
4. Check whether there are perforations in the heat exchanger plate of the gas hot blast stove. Usually, the magnifying glass is 5 times larger. The lamp or kerosene penetration method can also be used to check one by one.

5、若发现介质出入口短管及通道有杂物，则阐明过滤器失效，要赶紧清洗。一般板片常用的清洗方法有反冲法、手艺清洗法、和化学清洗法等。
5. If impurities are found in the short pipes and passages at the entrance and exit of the media, the failure of the filters should be clarified and the filters should be cleaned as soon as possible. Commonly used cleaning methods for sheet metal include backwash method, process cleaning method and chemical cleaning method.

6、换热板片结疤时，不要用钢丝刷或钢丝毛刷来洗刷，以防加快板片的腐蚀。若板片上有污点或铁锈时，可用去污粉铲除。切记用于清洗的水，不能含盐、硫等酸性成份。
6. When the heat exchanger plate is scarred, do not use wire brush or wire brush to wash, in order to prevent the plate from accelerating corrosion. If there is stain or rust on the plate, it can be removed with decontamination powder. Keep in mind that the water used for cleaning should not contain salts, sulfur and other acidic components.

7、拆开钛材的板片时，禁止与明火触摸，以防氧化。查看密封垫片是否有老化、蜕变、裂纹等缺点，禁用硬的物品在表面上乱划。
7. When dismantling the titanium sheet, it is forbidden to touch the open fire to prevent oxidation. Check whether the sealing gasket has aging, degeneration, cracks and other shortcomings, prohibit hard objects scratching on the surface.

8、密封垫片和换热板片的表面禁止积存固体颗粒，例如沙子还有铁渣等。
8. It is forbidden to deposit solid particles on the surfaces of sealing gaskets and heat exchanger plates, such as sand and iron slag.

9、查看换热板片是不是有部分出现变形，如果超过允许值的，因此需要实行修整或着是更换。
9. Check whether the heat exchanger plate is partly deformed. If it exceeds the allowable value, it needs to be repaired or replaced.
