industrial gas pellet boiler for paper machine
How to prevent corrosion of the gas industrial pellet boiler for paper machine gas boiler it if the temperature is too high, some of the components of the boiler working long hours in the intense heat of the environment at work, the situation will cause boiler corrosion occurs. So, we are in the process of work what to do to reduce the corrosion of it? Here to tell you about some of the methods of preventing corrosion of boiler gas. Reason and approach demands on internal corrosion of the gas boiler must be in accordance with the methods and principles of conduct, you can now use a more extensive domestic and international gas boiler corrosion detection approach is magnetic flux leakage and ultrasonic detection. Ultrasonic Ultrasonic detection is used to measure the wall thickness after etching using the principle of ultrasonic pulse reflection. The basic principle of magnetic flux leakage method leakage flux detection method is based on the high-permeability properties of the ferromagnetic materials, magnetic permeability of the gas boiler corrosion disadvantage is much less than the permeability of the furnace, the applied gas boiler is magnetized in a magnetic field effect, when the furnace is no disadvantage, most of the magnetic lines of force through the pipe. Uniform distribution of lines of magnetic force at the moment; when the internal elbow has the disadvantage that the onset of meander lines of magnetic force, and a part of magnetic lines of force from leaking out of the outer steel pipe. Detecting the escaping magnetic flux leakage outer elbow, it can be determined whether the shortcomings exist. When the probe detects a straight guide hot oil furnace inner wall emit ultrasound pulse, to receive from the probe first reflected pulse within the outer wall, and will receive the ultrasound probe, this pulse and the pulse reflected from the outer wall of the outer appearance of the reflected pulse trip distance between the reflecting wall thickness. Gas-fired boiler in accordance with the practices and conditions set forth in the demand for the detection of practice, in accordance with the detection of ultrasonic inspection method can be distinguished way. High temperature components such as a gas boiler front panel, convection superheater and reheater temperature is the primary structural member and the like inside the boiler, a very long time to work in the harsh environment of use of the medium flame, smoke, ash, etc., and therefore the working process changes occurred in the organization and function of a range of materials, these changes hit the gas boiler creep, fatigue, corrosion, erosion and other messy aging and failure mechanisms. These high temperatures Microstructure component material will follow the extension of working time deteriorated creep damage occurs, such as loose pearlite, spheroidized carbides, grain boundary and growth mobilization, holes creep, intergranular cracking occurs .
2, tightness test
Indoor gas boiler pipes tightness test should be consistent with the following requirements:
① low pressure gas pipe test pressure boiler for planning a pressure not less than 5kPa, under the experimental pressure regulator least 30min, and view all the joint with the blowing agent, no leakage, no pressure gauge pressure drop qualified equipment. When the experimental system stainless steel corrugated hose, plastic composite pipe, oil hose, when the plastic cover brass, IH pressure not less than the experiment, in addition to sealing the respective view point, the end surface of the cladding layer should also whether there is leakage phenomenon View.
② medium pressure gas pipelines boiler pressure test planning more pressure and not less than 0.1Mpa. Under the experimental pressure regulator less than 2h, and view all joints with a blowing agent, no leakage, no pressure drop pressure measurement device qualified.
There are a lot of oil refines in Pakistan. And Pakistan also has rich oil, petroleum and gas resource. Last week, we got an inquiry of 10 ton oil fired steam industrial pellet boiler for paper machine from Pakistan. Our consumer kindly provided our lot of information about his requirements such as boiler capacity, boiler fuel, boiler pressure, boiler application, boiler temperature, oil refines condition, etc. Those information can save our time. And our consumer can directly receive specialized engineers advice. Our engineers is making plans for this oil refines project in Pakistan.
We produce steam industrial pellet boiler for paper machine is a very important part of the device, this provides a quick way to our gas steam boiler, after use, we found an excellent energy-saving effect boilers, flue gas discharge temperature is lower than the previous boiler equipment many, in line with national environmental provisions of the boiler equipment. --customer feedback
