24mv medium pressure boiler applied in school
Gas hot water 24mv medium pressure boiler applied in school blowdown sewage treatment technique which is a process of boiler operation, a link must be aimed boiler blowdown is to drain the water with a higher salt concentration pot, and the pot of water, corrosion and sediment the salt content in boiler water is maintained within a prescribed range, so as to reduce the expansion of the boiler water and the foam layer occurs, thereby reducing the salt content and humidity of steam to ensure good quality of steam. At the same time, the sewage may eliminate or mitigate fouling in the evaporator by the surface of the pipe. Classification of gas hot water boiler blowdown: gas hot water boiler blowdown discharge points on a regular basis and continuous blowdown two kinds. Continuous blowdown: also called surface discharge is continuously draw off a portion of the boiler water, the purpose is to let go of the salt was dissolved in water and the pan pot water surface float. Regular Drainage: emission time per predetermined time, the main purpose is to let go of the precipitated water boiler slag, of course, with a pan of water soluble salt. Its emissions group should be more precipitation the lowest part of the boiler slag. Gas hot water boiler blowdown techniques: good when compared to the sewage at low load low load boiler water level slightly higher vapor pressure boiler water circulating slowly, resulting in easy accumulation of dirt in the drum, the bottom of the collection tank, and the high vapor pressure high blowdown water flow rates, to facilitate the discharge of dirt. Further, when the boiler blowdown must be provided for hand operation, the water level to be closely monitored to prevent the water preferably should be operated to maintain the sewage level again at around 60%. Drain valve open should be short intermittently every sewage quick-closing speed of the opening, causing the slag scale disturbances, thus repeated several times, the precipitate was suction rely possible to quickly meet at outfall, then concentrated discharge. To control the right time, not too long, usually once a sewage must be in the 30s of the time. If the discharge time is too long, the water content of soil furnace will be gradually reduced, so the effect of variation not only sewage, emissions have increased, not only a waste of energy, but also affect the boiler water circulation, and even burst pipe failure may occur. Observation of the given row after the flash tank vapor emission mouth, must touch the outfall temperature, and view given row Expander air outlet, in order to determine whether or not to confirm the drain valve is fully closed. Ruoyin debris stuck in the spool of the leak can be re-opened after a rapid close, if the issues shutting the valve wear and difficult, should strengthen surveillance, arrange repair or replacement as soon as possible, at the same time, should be prepared to shift on the record corresponding record, for subsequent inspection. In summary, the work of boiler blowdown, we must try to do a good job, both to ensure the smooth operation of the boiler, also can guarantee the life of the boiler.

Chemical plant to solve large measure 24mv medium pressure boiler applied in school fan noise What? Chemical plant to solve large measure boiler fan noise What? Currently in use in many companies, industrial production and demand for heating, the boiler is very popular. However, due to the noise boiler many factors affect the work and life of the surrounding residents, endangering people's health, thus controlling chemical plant boiler fan noise has become essential. Blower and Bei induced draft fan sound in the boiler room is generally 90dB down, since the transport of the boiler flue gas temperature as high as 180 ℃, if a closed sound results in poor heat dissipation, the motor temperature is too high, or even burn out the motor. Thus, the fan noise and general binding energy in the process. Practice shows that comprehensively harnessing energy boiler fan noise reduction process is arranged to maintain constant the boiler room, the blower fan and primer were placed soundproof chamber, the t-joint connection with the host. Ventilation duct, a top wall soundproof chamber or open the intake port, and a muffler installed, for the air intake of the engine room. When arranged close to the fan side of the boiler room, in the upper portion of the intake port, the motor is placed in the central airflow passage. When the boiler operation, since the negative pressure in the blower noise generated by the chamber, a large amount of fresh outdoor air into the soundproof chamber automatically. First, the induction heat exchange with a cooling fan motor, the indoor temperature is kept at 50 ℃.
How to maintain water supply and 24mv medium pressure boiler applied in school water of Fangkuai boiler during operation the quality of water supply and furnace water of Fangkuai boiler should meet the requirements of GB/T1576-2008 (Industrial Boiler Water quality). And sample and test regularly. The quantity and frequency of the discharge shall be determined by the laboratory personnel. Test and discharge shall be recorded in detail. 2 Monitoring of rotating machinery shall be carried out by means of one look, two ears and three touches for pumps, fans, pumps, etc. The discovery of anomalies, that is, take measures to deal with. If necessary, the furnace should be shut down and overhauled, but it should not be careless. The oil level of the tank on the 3rd day If there is no automatic control device for oil level, the oil level should be checked regularly and it is found that the oil level is too low to be used for 2 hours. Please inform the fuel personnel in advance of the injection of new fuel. 4 the water level control of the soft water tank is generally used to automatically control the operation status of the 5 water treatment equipment to check periodically for the failure of ion exchangers in the water treatment equipment. Under normal conditions, the exhaust temperature of the new Fangkuai boiler is generally low, and will gradually increase with the increase of the running time. If it is found that the change is too large and exceeds 20 ℃, the appropriate time to shut down the furnace and clean the ash should be chosen. Such phenomena as If it happens frequently, check that the combustion system is normal. If the oil pressure is too low, the oil temperature is too low to atomize bad, or the air-oil ratio is not correct, resulting in bad oil-gas mixture, resulting in anoxic combustion and carbon precipitation. In addition, for dry-backed boilers, if the exhaust temperature increases abruptly, it is possible to leak smoke from the fire-proof wall between the second and the third return of the rear chamber, which needs to be repaired.
