fire tube gas boiler supplier
"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small fire tube boiler suppliers county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.
In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.
Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.
After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "
This year the city built-up area of the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.
City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
If natural gas as fire tube boiler supplier fuel choice, because the convenience of clean natural gas and fuel used in the boiler service life will be over 10 years; but if it is a boiler coal or other fuels, it will shorten the life of some. Further, the life of the boiler with the use of the frequency, the higher the frequency the shorter the life of the boiler, the greater the contrary. Late boiler maintenance is also very important for the life of the boiler, good maintenance will extend the life of the boiler.
How to prevent corrosion of the gas fire tube boiler supplier 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 .
According to the characteristics of biomass straw, I am in a circulating fluidized bed fire tube boiler supplier technology has been developed based on an adaptation of straw biomass circulating fluidized bed boiler for sale, to avoid or solve biomass combustion and heat transfer process fouling and slagging problems and long-term stable operation. Flue gas emissions to meet the relevant national environmental standards, low carbon content of ash, fly ash utilization can be achieved.
