what is boiler in ship
New what is boiler in ship inspection work is needed by the boiler and pressure vessel safety inspection department, new boiler through its approval, supervision, and related performance tests. After testing by the boiler manufacturing unit can be formally delivered to the use of units.
When the what is boiler in ship after a failure should be promptly dealt boiler, auxiliary equipment occurs due to the abnormal tiny leak or the boiler itself and burn local overheating phenomena, after timely treatment (timely stop or pause), can resume normal operation, depending on the boiler malfunction. After the boiler failure if not promptly treated, may lead to an accident, it must be given sufficient attention. Boiler equipment operation at any time are likely to be some anomalies, but behind these phenomena are often some kind of operating equipment failures and accidents aura. Which in addition to defects in the equipment itself, but also may be due to unskilled personnel to run the operation, negligence or misuse caused. Therefore, the operating personnel not only to master the technique, but also master the basic method to determine fault in order to properly determine and deal with failure, to avoid accidents and reduce losses in accordance with the operation of some of the anomalies. Typically, substantially determine the fault or accident three main methods, i.e., direct analysis method, the indirect method of analysis and synthesis. Direct analysis method is based on boiler operation intuitive phenomenon, with human sensory organs and experience to directly determine the point of failure, which is a basic method. With the growth and continue to accumulate experience in running time, it will use this method skillful. Indirect analysis method is based on professional knowledge-based, to determine the accident or malfunction by the process of logical reasoning under the direct control analysis, familiar with the equipment system premise. To achieve timely detection of faults and correctly determine fault, only to master the direct analysis is not enough, because most failures or accidents, often showing one or more indirect, implicit in the initial phenomenon occurs, it will not It can accurately judge. Therefore, the operating personnel in mastering the direct analysis at the same time, to gradually learn and become familiar with the indirect analysis. Occurs such as when the boiler flue gas temperature is low, the fault can not be determined directly, but indirectly by analysis of the heating surface can reflect a defect. Comprehensive analysis is a direct analysis method and indirect analysis of organically combined. For the gradual failure implicit features, with particular attention to the comprehensive judgment. This method is based on the surface of several phenomena, the main feature to check to find malfunction in the integrated cross several phenomena, determine the nature of the fault and the final position. Then, take appropriate measures to prevent the failure to expand. In short, the operation of the boiler, when the abnormal phenomenon, should find the problem in different ways according to experience, to determine the nature and location of the fault. In the current, the more Instruments, higher degree of automation, the operator can find signs of failure or an accident situation by displaying the instrument, and then checked again to confirm targeted fault location.
It is reported that Jinjiang City of Fujian Province will be fully started tackling air pollution prevention and control work, Market Authority as a proactive, Take Measures to promote coal-fired what is boiler in ship renovation work.
Market Authority through three initiatives to further improve the environmental air treatment Jinjiang City, Jinjiang create "blue sky": strict criteria, the better the mark.
Actively cooperate with environmental protection, by letter and other relevant departments, coal-fired boilers do not meet environmental policy, shall not start to inform, Supervision, Inspection and registration certificate for the use of strict coal-fired boilers access gateway, departmental interaction, ensure its effectiveness.
Strengthen communication and coordination with environmental protection, by letter and other related departments and Towns, a solid job of remediation coal-fired boilers, out of work.
Combined area of gas supply, heating pipe network coverage, and vigorously promote the use of natural gas, electricity and other clean energy, and take the way government subsidies, coal-fired boiler to remove their push to ensure the prevention and control of atmospheric achieve results.
Step up publicity services in place. Organization of the market supervision area of propaganda out of coal-fired boilers policy of the increase, according to the sense of service, "a visit to promote a" do a good job guidance subsidies, removal and cancellation of work, and guide to remove their coal-fired boilers, and required to apply for removal of cancellation.
Poor water quality adverse effect on the industrial what is boiler in ship water quality caused by adverse negative impact on the industrial boiler caused by (1) the formation of scale. Most likely to form a variety of adverse water quality scale, this will affect the performance of industrial boilers. The reason for the formation of scale, mainly because the steam can release a lot of energy, which energy is transferred to the water, if poor water quality, the boiler heating surface will therefore have a scale, whereby the thermal conductivity will reduce the boiler, the boiler energy consumption greatly increased. The size of the thermal conductivity can be used to measure the thermal conductivity of the object, the thermal conductivity of the scale will be a lot lower than the thermal conductivity of steel, which will definitely affect the thermal conductivity of industrial boilers. (2) boiler corrosion. Poor water quality can also lead to corrosion problems boiler. Especially waterwall, economizer and other metal parts of the drum will thus deformed more weak, and even the formation of leakage, destroy the original structure, reducing the strength of the metal. In this case, the boiler corrosion problems increasingly serious about the safety of the boiler severely affected, can not function properly. Boiler heating surface there will be metal corrosion products, which is more likely to lead to more serious quality problems boiler. Under the scale, cracks, leaks and other problems emerge, a number of difficult to effectively remove debris, clogging pipes, greatly enhance the difficulty of maintenance of the boiler. In addition, during maintenance, due to difficult, it takes more time and effort, improve maintenance costs. (3) induced accidents. Due to poor water quality-induced accidents abound. According to statistics, the scale accidents caused by condensation caused by about 20%. After the accident, the device will not only suffer losses, but also cause great risk to the personal safety of staff. Therefore, to reduce accidents, improve economic efficiency, on the need to strengthen water boiler.
