CDQ boiler water quality control

ram. Regeneration of the traditional method of floating bed,belstaff italia, recycled resin to maintain a renewable liquid layer in the 100mm, the resin bed Amberpack story, from the mirrors can not see the regeneration of the water level, we have the actual situation of the device. Innovation of the full water reclamation law, put into effect after the regeneration. Greatly increased the Yin and Yang bed Cycle Water. Improved water quality, mixed-bed system for water cycle and water quality greatly improved. Table 2. 2.2 The DH value of water to adjust my scope of plant boiler feed water pH 8.8 to 9.2. Initial operation, the ammonia in the ammonia tank and diluted by adding liquid ammonia pump will be added to the addition of ammonia Received Date :2008-04-15 Description: Gu Xiao (1971 a). Male. Assistant T engineers saline mother tube. This method is choking odor of ammonia solution,asics running shoes, ammonia concentration determination difficult. And in the bottom of the drain valve at the sample,Abercrombie Hoodies, the valve is frequently opened, frequent leakage. After trial and error, we ammonia ammonia tank filling time control. New replacement rechargeable ammonia ammonia bottle about 5min, using about 15 days. Extended to 1015min, the control tube desalination jellyfish pH value of 9.49.5. Meanwhile, according to the measured concentration of water pH on the ammonia tank to adjust pH to the basic maintenance of water between 9.0-9.1. In addition. Because ammonia bottle of ammonia to the ammonia tank charging is endothermic reaction, severe winter ice bottle of ammonia. Serious about 30ram thick, liquid ammonia can not overflow. Heating in Canada after the installation of ammonia asked, no freezing phenomenon, 200kg of liquid ammonia from the l0 days of using the time to 30 days,ugg botas, the water pH from the 8.88.9 to 9.09.1. Table 2 full of water and regeneration of the comparison with the traditional regeneration methods Kui ... standard PNa:. . , _ Tan :5-201z method Bureau of the system of water, t4o00o00SiO, _ :10-20 / L Conductivity :0.1-0 .21xS/cml5O00SiO2 :2-10tzg / L Conductivity: <o. 13IzS/em6OO002.3 control of dissolved oxygen in water dissolved oxygen content in water can cause excessive corrosion of pipeline oxygen. Mainly by the dissolved oxygen content in water deaerator pressure, temperature, exhaust valve opening at the top of the decision. Sometimes essential to reach the temperature and pressure ratings. However, excessive dissolved oxygen, through the deaerator top of the exhaust valve opening is adjusted, the dissolved oxygen will be reduced to the specified value or less. Deaerator rated condition does not meet dissolved oxygen content can cause excessive water. In actual operation, we measured the dissolved oxygen content in accordance. Timely adjustments to the deaerator operating conditions, the water dissolved oxygen control in 7g / L or less. 2.4 The boiler water boiler water quality control water quality and the main indicator is the pH value P0. PO boiler start is qualified and the situation of low pH, by adding NaOH solution. Running normal, use of the boiler dosing (NaPO) the method of pH, P043-adjusted. Initial operation, (continued on page 60) m �� P2 embroidery usurp a tendon transfer of re-unification parties Health Law Fuel & Chemical Fuel & ChemicalProcesseslulv2008V () 1.39No. 4 Gas - water quality from the DN1 hard, the water temperature is too low there will be brass scale attached to the heat exchanger, causing congestion, so the water temperature controlled at 20-22 ��. 4 Conclusion LiBr double-effect steam absorption chiller transformed into direct-fired lithium bromide absorption chiller, coke oven gas to methanol synthesis purge gas after the refrigerator instead of the steam used to achieve the technological system (on the next 19 pages) of cold water and applied to production, so let dissipated in the effective use of purge gas, steam annual cost savings of more than 200 million, reducing production costs. The result shows. The transformation of the refrigerator was a success, achieved the expected results. I solved the steam plant due to lack of refrigerator instead of the normal operation of the problems and ensure the production of my plant normal operation of the summer. Table 31,2 # boiler water analysis records to intermittent dosing, PO43 ~ rising fast, but frequent dosing pumps open, PO43 one fluctuated. After running for some time instead of continuous dosing. Add kits to adjust the concentration, P043 one maintained at 5mg / L or so, pH value between 9.5 to 10, the furnace water stability. 2.5 Boiler Blowdown control it is necessary to control the boiler water, but also on time and on the boiler sewage, even the normal sewage discharge control valve opening is 5%. 1 time per day given row, each row of the valve open the scheduled time of 20s, the total discharge rate of the boiler control in �� 2%. 3 Conclusion Through the above control measures to ensure the stability of our plant CDQ boiler water, steam quality is better (see Table 3), more than a year after a production run, in the repair of CDQ in question, check the boiler drum , furnace tubes, turbine blades, no significant corrosion and scaling phenomena.
