The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Yunnan Steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. vertical Steam generator how much Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.

The main parts of the waste heat boiler can be divided into drum, pipe, header, membrane wall, tube panel, tube box, etc. These parts are the parts with specific process requirements in the waste heat boiler. Yunnan Steam generator For example, the drum should go through metal flaw detection, heat treatment, hydrostatic test and other processes to improve the stability of the waste heat boiler. At the same time, because the header needs high sealing, manual welding is required, and the welding quality needs to be tested. It can be seen that due to the complexity of the working environment of the waste heat boiler, it has special requirements for its internal structural members. vertical Steam generator how much In the process of designing and manufacturing the waste heat boiler, the process designer should consider the advantages and disadvantages of various processes, and then select a reasonable process to complete the manufacturing of the waste heat boiler. For example, the serpentine parts in the waste heat boiler cannot be bent automatically by the machine, so they can only be bent manually.

The long-term use of gas-fired boilers will inevitably lead to problems of one kind or another. However, the working principle of gas-fired boiler is complex, and the price of gas-fired boiler is particularly high, so it is necessary to select high-quality gas-fired boiler manufacturers and companies with good after-sales service. Yunnan Steam generator In addition, what should we do if the gas boiler fails? As the gas-fired boiler involves the construction of gas and lines, the professional installation personnel of the manufacturer must check the installation at home, and the professional personnel shall install it. Improper installation will bring a series of problems for future use. vertical Steam generator how much The existing pipes and radiators in China need to be observed by professional engineers and installation personnel to determine whether they can continue to be used. If the service life is long, the heating system may scale more. It is generally recommended that the user replace it to obtain better heating effect.

The waste heat boiler is composed of drum, movable smoke hood, feeding pipe groove, oxygen lance mouth, furnace mouth section flue, inclined section 1 flue, inclined section 2 flue, last section 1 flue, last section 2 flue, nitrogen sealing device and nitrogen sealing plug, manhole, micro differential pressure tapping device, flue support and hanger. Yunnan Steam generator Unlike conventional boilers, waste heat boilers do not produce combustion process and do not have combustion related equipment. Essentially, they are just gas water/steam heat exchangers. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of flue is introduced from the drum through downcomer to the lower header of each flue, and then enters into each heating surface. The water passes through the heating surface and generates steam into the header, and then is introduced into the drum through the riser. vertical Steam generator how much The needle tube waste heat recovery device is a special high-efficient energy-saving product specially designed for waste heat recovery of flue gas. The heat recovery boiler uses needle shaped tubes to strengthen the heat elements to expand the heating surface. The heating surface on the water pipe smoke side can be greatly increased. At the same time, the smoke will form strong turbulence when passing through the needle shaped tube surface, which will improve the heat transfer efficiency and reduce the soot accumulation.

Gas steam generator is also called gas steam boiler. The steam temperature is not high when the steam gas and steam generator has a fault. How can we solve this problem. Yunnan Steam generator Generally, there are two situations: physical characteristics of water vapor: it will evaporate when reaching 100 ℃, and it is impossible for steam to reach a higher temperature. Although the measured temperature of steam is higher when it receives pressure, the temperature will drop to 100 ℃ as soon as it reaches normal atmospheric pressure. vertical Steam generator how much The way not to imagine that the pressure of the steam engine will rise is to make the steam negative pressure. Every increase of about 1kg in steam pressure will increase the steam temperature by about 10 ℃, so by analogy, you need to increase the pressure as much as you need the temperature. I hope it is useful to you.

When using stainless steel storage tank, cracks appear on the head. If it is not handled in time, it will be dangerous, and how to handle this situation will be explained. Yunnan Steam generator Firstly, the cracks in the stainless steel tank can were removed by polishing. After grinding, pits that do not need repair welding and do not affect the grading shall be formed within the allowable range. Otherwise, repair welding shall be carried out. The position of surface crack defect shall be determined by surface penetration defect detection, and the welding repair shall be completed. The horizontal gas tank shall be repaired, and the weld and surrounding materials shall be repaired. After that, argon tungsten arc welding shall be used for repair welding. vertical Steam generator how much Tungsten argon arc welding shall be adopted for welding repair. It is suitable for back welding or skip welding, small size multi-layer and multi pass non rotating welding to avoid overheating of the weld. Water cooling measures are adopted. The defects of stainless steel storage tanks shall be removed by grinding with angular grinding wheel with conical grinding rod. Note that the abrasive grains of the grinding wheel should be perpendicular to the crack length. If the defect is deep, crack stop holes shall be drilled at both ends of the defect to prevent the crack from expanding with the grinding process. According to the inspection, in the stainless steel storage tank with primary side inspection, there are cracks at the head welds, and these defective welds have different edge bite degrees. Do not panic when the stainless steel tank can has cracks. The oil tank works. The above measures can be taken to solve this problem.
