Maintenance of the boiler and burner maintenance 1, boiler maintenance and deactivation of backup boiler, should take anti-corrosion measures. 1) maintenance Calorimetry: maintaining the furnace pressure 0.05 ~ 0.09MPa, the water temperature of about 100 deg.] C, to prevent air entering the boiler, this method is suitable within a boiler shutdown week. 2) Wet maintenance: After disabling the boiler, put the water came out, the interior completely remove the dirt and cleaned, refilled been handled well demineralized water, softened water filled boiler. Then adding alkali to the boiler, when added with sodium hydroxide aqueous 5 kg per ton to 6 kg, per ton of sodium carbonate was added if the water 18 kg to 20 kg per ton of water when trisodium phosphate is added 10 kg to 12 kg, maintaining the PH value above 10. The furnace was then heated to 100 deg.] C water, the safety valve is opened, air is discharged in the furnace, and then closed. During maintenance should always check and found that leak that is to be cleared. When the boiler is enabled, it should be drained alkaline solution, and rinse with water, especially when the plot scale boiler must deactivate more clean, because the scale can be soaked in lye and fall off, clog pipes. The method is suitable for longer-term disabled boiler. 2, the burner maintenance: 1) cleaning and maintenance of the burner: Open the combustion head, with a cleaning wipe member or combustion gas, a flame detector wipe with a clean soft cloth, carefully clean the duct and the fan wheel. 2) maintenance of the oil (gas) passage system: Remove fuel (gas) pipeline, cleaning fuel (gas) each filter and nozzle, the drain valve is opened daily oil tank, with exclusion of moisture and impurities in the waste oil. 3) maintenance circuitry: Check whether each wiring is connected firmly assembly is intact and the like.
Burns Hospital Affiliated Hospital of Shanxi Linfen Linfen Steel is attending a hospital burns burns and other diseases. Hot water boiler is essential hospital equipment heat, hot water output can provide disinfection of medical instruments and ward heating demand. With constantly improving our environmental policy, boiler correspondingly introduced more sophisticated Use. Linfen hospital burns to respond positively to the national environmental policy, decided to introduce an environmentally friendly low nitrogen gas 130 th fired hot water boiler shipped to argentina. Taking into account the special circumstances of the hospital, the boiler should also have the use of safe, clean overall characteristics. Based on the above considerations, finalize the Linfen hospital with burns boiler party cooperation fast, fast is provided by one side of a gas condensing pressure hot water boiler (CWNS2.1-95 / 70-Y.Q).
Hot water boiler belongs to special equipment, and is also a kind of high temperature and high pressure thermal energy equipment. It is inevitable that some faults will occur in the process of operation, which are normal, but it is very likely that the explosion of 130 th fired hot water boiler shipped to argentina will occur if it is not properly dealt with. Therefore, for equipment safety and personal safety, we must understand some prevention hot water boiler explosion common sense. In the design of hot water boiler, thermal calculation and strength calculation should be carried out strictly according to the requirement, the structure layout should be reasonable, and the material selection should be qualified. In order to ensure the boiler quality conforms to the drawing, the boiler should be constructed according to the drawing. The degree of delimitation. Boiler safety accessories should be complete, agile and reliable, and on-time maintenance, frequent inspection, failure of accessories should be replaced in a timely manner. Repair and repair the boiler inside and outside the boiler according to the schedule, repair and reform the existing problems in time to ensure the quality of inspection. 2. Fuel oil and gas-fired hot water boiler explosion accident in furnace to prevent explosion of hot water boiler should be carefully checked before the point of the hot water boiler, whether the oil path is tight (leakage), the pressure is normal or not, and the newly installed and modified oil and gas pipelines must be blown clean. Check whether the blower has been ventilated for 5 minutes before ignition, and analyze the reasons after ignition failure, and then follow the ignition procedure to penetrate the air. Ignite. For boilers that have not been certified for boiler use and annual inspection, the grater has the right to refuse to light the furnace. The enterprise should lay down the experienced stoves who have rich experience in the operation of the furnace. The staff of the furnace should step up the tour inspection, deal with the problems in time, prevent the flameout, and stop the fuel as soon as it is found out. The boiler shall be equipped with automatic protection devices, including automatic ignition, flameout protection, automatic combustion regulation and necessary interlocking alarm protection devices.
Boiler basic knowledge and principle: as a heat carrier, pump forced circulation of liquid phase, then return to reheating, direct-flow special industrial furnace. Widely used in foundry sand molds such as petrochemical, textile, printing and dyeing, plastics, rubber, food processing, wood processing, asphalt heat, carton production, vegetable dehydration, drying and so on. Boiler is an energy, safe, heating equipment, is an ideal alternative to steam boiler products. The working principle is that the oil heater (endothermic) (organic heat) which is transported to the various thermal equipment after heating, the heat conduction (heat energy release), and then back to the furnace, forming a closed circle in the sense of meaning. In order to achieve the purpose of heating in the process of education. Performance and characteristics: 1, low pressure and high temperature. With the increase of temperature, the viscosity of the oil will continue to decrease the resistance of the system, but also reduce the working pressure, more conducive to safe operation and safe operation. Steam boiler is a high temperature and high pressure plume. 2 the heating system adopts hot water and equipment inlet and outlet temperature of 20? 30 degrees closed-circuit forced circulation heat can be recycled repeatedly there is no waste thermal efficiency is high energy-saving effect is remarkable. (3) the pressure of the heating system is low and the requirements of the pressure equipment and its system will also be reduced accordingly. Therefore, the steam pot required by the production process is accordingly reduced. The furnace is simple and the investment cost is low. 4, the thermal efficiency of various loads can be maintained at an optimal level, and can be adapted to the production of heat load requirements of the following types of 320 degrees, temperature can be accurately adjusted and controlled. 5, heaters to increase two to three times the cycle can provide a wide range of temperature processes for a variety of equipment to meet different temperatures that greatly reduce the need for equipment investment.
