clean water tube single drum biomass pellet boiler

The temperature difference between the wall surface of the vertical steam clean water tube single drum biomass pellet boiler steam is generated during the vertical steam boiler generates steam, and pressure in the heating, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the temperature of the lower wall, and wall thickness of the vertical bubble there is a temperature difference between the walls, i.e., the inner wall temperature of the bubble is higher than the temperature of the outer wall, the wall temperature is higher than a temperature lower wall, an outer wall and inner wall temperature is higher than the temperature of the inner wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature of the lower wall , the wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature at the wall, the inner wall temperature is higher than the outer wall temperature. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. In order to prevent excessive thermal stress, it is necessary to slow the vertical steam boiler booster. Vertical steam boiler ignition and boosting process conditions steam parameters, each component level and also changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange closely monitor vertical steam boiler various instruments directive professionals change. Since the vertical steam boiler water temperature continues to rise, the metal wall temperature of the bubble and the evaporator heating surface begins to rise at any time, it is necessary to pay attention to temperature and thermal stress of thermal expansion of the bubble, since the bubble wall thickness is relatively thick, so vertical the main problem in the steam boiler heating thermal stress. At the same time, also considering the overall thermal expansion problems, especially vertical tube steam boiler heating surface, since the wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused.

What issues can explore the coal-fired hot water clean water tube single drum biomass pellet boiler? For this kind of boiler coal-fired hot water boiler, I believe we are not unfamiliar, because it is one of the site boiler products, so in front, has already begun work in this area of ​​knowledge to explain, so that we have the learning content, thus come gradually, and as soon as possible to achieve this objective and comprehensive requirements. So, here is no exception, is on this kind of boiler, however, is something new to learn proceed. 1.1 tons of coal-fired hot water boiler 1 hour to 45 degrees how much hot water? This, then, depends on the basis of the boiler water temperature is. However, in general, if one ton boiler temperature is 40 degrees, then it on the water, it is generally within the range of 10-15 tons. Therefore, it should be clear. 2. In the coal-fired hot water boiler, whether it is the higher the pressure, the higher the temperature in the furnace, the faster the speed of the boiler water cycle? In addition, one ton of coal-fired hot water boiler, heating area can provide much? And, in the heating, boiler which we can use to achieve their goals? One problem, the answer is yes, but also know that, in the coal-fired hot water boiler, the higher the pressure, then, for boiler water circulation is better. But it is also a limit range. As for question two, the answer is 10,000 square meters of heating area. For the three, the answer is for the gas hot water boiler, oil hot water boilers, hot water boilers burning biomass, coal-fired hot water boilers, hot water boilers, etc. These and alcohol. 3. Thermal efficiency of coal-fired hot water boiler, what should you consider? For this coal-fired hot water boiler A boiler, in which the thermal efficiency, different manufacturers, which is somewhat different. As well as differences in the manufacturing process, but also lead to different thermal efficiency. In addition to these two, and method of operation, fuel type and the like, sometimes need to be taken into account. In general, which in normal circumstances, reaching over 90%, there is no problem.

Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station clean water tube single drum biomass pellet boiler piping material quality safety risk prevention and control (the "Notice"), to further enhance the quality and safety supervision and management of boiler tubes, effectively preventing security risks, protect the power production safety , as follows.

First, carry out the verification of boiler tubes

The electricity business, special equipment manufacturers to immediately organize boiler tube inspections, to verify whether the focus of the pipe to meet the technical conditions stipulated orders, including the source, size, quantity, quality certificates, raw material procurement contracts, procurement contracts and other piping components. For imported pipe material, but also the verification of the customs declaration, commodity inspection report (proof of entry inspection and quarantine of goods), combined with the production, inspection and testing during use and operation of the situation, in-depth investigation pipe quality boiler safety issues and risks.

Second, effectively prevent security risks

Boiler pipe quality and safety hazards or other problems threatening the security and stability of power station boilers, power companies, special equipment manufacturers to take practical measures immediately, the complete elimination of quality and safety problems; there are significant quality and safety problems, it should stop running generator sets , boiler or stop production and sales of the pipe elements, and replace the boiler pipe complying with relevant standards.

The actual boiler pipe manufacturing unit is unknown or if there are doubts, the relevant information or data can not be traced authenticity, power enterprises, special equipment manufacturers to immediately in accordance with industry standards, inspection and testing institutions have entrusted the appropriate qualifications for boiler tubes were identified test. Test results show that failed boiler or pipe quality does not meet the technical requirements stipulated in the order, power companies, special equipment manufacturers to eliminate hidden dangers in a timely manner or be replaced.

Third, strengthen the source of control boiler pipe

Special equipment manufacturing enterprises, power enterprises should strengthen boiler pipe source control, in strict accordance with the standard provisions of China's relevant laws and regulations and orders technical conditions agreed to carry out boiler pipe design and manufacturing, procurement orders, admission acceptance, inspection and testing, installation and commissioning work, resolutely eliminate substandard or counterfeit boiler pipes enter the field of electricity production; to strictly implement the special equipment safety supervision and management regulations, establish and improve the technical archives and long-term care, to ensure that relevant information can be traced back.
