automatic horizontal cng fired boiler

It can increase the application range of heat transfer unit equipment and the design scope of heat transfer operation in process design, which has the advantages of rapid cooling and heat transfer capability and smaller temperature difference between heat transfer and heat transfer, which can increase the application range of heat transfer unit equipment and the design scope of heat transfer operation. It also provides possibility for some previous designs which are limited by heat transfer rate or temperature difference, such as recovery of heat energy by small temperature difference, small temperature difference cooling, rapid and accurate constant temperature control and so on. This is due to the fact that plate heat exchangers are also thin-layer heat exchangers. The thermal deviation of each parallel heat pipe group should be reduced as far as possible, for which the return water of the system entering the automatic horizontal cng fired boiler should be adjusted and distributed. For ordinary low-temperature hot water boilers, the hot water flow rate is large, can The natural distribution, that is, the amount of water entering each parallel pipe group, is allocated naturally according to the heat condition of each pipe group and the size of pipe resistance. Although the structure of natural distribution is simple, but the safety and reliability of boiler operation is poor, for high temperature hot water boiler, the relative water quantity is less, so it is not suitable to adopt natural distribution mode, but the valve should be used to adjust the distribution, according to the size of heat load of heating pipe group, Supply the corresponding circulating water to ensure that the outlet water temperature of each parallel loop does not vary greatly. At this point, the outlet water temperature deviation of each loop can be controlled within 10 degrees Celsius. The heat pipe of the retrofitted hot water boiler must be kept to a certain extent. Water flow rate to ensure heat pipe cooling, prevent oxygen corrosion and the deposition of impurities in the water. The downlink heat pipe should also maintain sufficient water speed. After modification, the stagnant zone of water in the boiler should be reduced as far as possible, especially at the end of the drum. Otherwise, oxygen corrosion can be easily caused. In order to remove the gas from the water in time, the exhaust valve should be set at the highest point of each loop of the boiler. When refitted into forced circulation hot water boiler, measures should be provided to prevent sudden power outage and kettle vaporization when pump is stopped.

3, looking for formal professional

There are many boiler company, scale, formal, professional renovation company does not have much. Boiler is a highly technical operational work, a large scale, qualified and experienced the transformation of the company, in the transformation, can avoid many failures due to technical immaturity caused.

Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station automatic horizontal cng fired 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.

Special equipment manufacturing enterprises, power companies are finding there are significant quality and safety risks of boiler tubes, to report to the local market regulators, power management departments and the National Energy Board sent energy regulators, and to take effective measures to thoroughly rectification to ensure the safe operation of generators . Provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps Market Authority (Hall Commission) should work together with the same level of power management departments, the National Energy Bureau sent energy regulatory agencies and other units, the organization of supervision and inspection, supervision and hidden rectification, effectively preventing security risks.

How much steam automatic horizontal cng fired boiler in some places the price of wine is wine is wine to be distilled means, so customers ask for steamed wine steam boiler steam boiler is brewing for the brewing process is there are a lot of places need to use steam. Visible steam in the brewing process need to use a lot of places. Brewery in the selection process of the steam boiler, there are many areas that need attention. For a lot of products between the various boiler manufacturers to be compared. Recently, there is a wine enterprises to fast boiler consulting, want to buy a steam boiler wine, but for the specific model and the price is not very understanding. So, here you need fast boiler technician helped carry out accounting. After the fast boiler technical personnel accounting, concluded that the brewery with a steam boiler 2 tons is possible. Currently, the model price of about 250,000. So, the price of the wine business for steam boilers wine already have a detailed understanding.
