Boiler oxygen equipment startup and shutdown procedures, processes 1, check before starting low pressure vacuum boiler oxygen equipment (1) confirm the vacuum pump to start licensing conditions are met, Steam Turbine Shaft Seal has been put into operation, the shaft seal pressure is normal. (2) the vacuum pump running from the DCS screen, check the vacuum pump inlet, gradually increase the negative pressure, an inlet pneumatic valve opens automatically. (3) Check the pump motor starting current time and the return to normal, bearing vibration, moisture separator and exhaust normal level. (4) Check the plate heat exchanger is working properly, the vacuum pump sealing water inlet temperature is normal. (5) by the same procedure, the other two in turn starts the vacuum pump. (6) When the vacuum unit normal, disabled, according to a vacuum pump for backup. (7) can be put into the system to start the vacuum pump started using function group. 2, the step into the deaerator (1) confirm the deaerator electric door starts exhaust, continuous exhaust bypass valve in an open position. (2) When the condensate system rinse qualified, open the door deaerator drainage wash, rinse deaerator Sheung Shui. (3) eliminates the oxygen water quality standards, the water level dropped -900mm, close deaerator drainage flush door. (4) administration deaerator auxiliary steam heating, to turn on the auxiliary deaerator steam isolation tone front door slowly open auxiliary steam pressure control valve to the deaerator, the deaerator feed water control temperature of not more than 4.26 ℃ / min, Note that during heating deaerator vibration, such as when a large vibration, the heating rate should be slow. (5) heating process deaerator administration, continue to use the deaerator Sheung condensate pump to the normal level. (6) When the temperature reached 100 deaerator deg.] C, the exhaust start off electric gate, the auxiliary steam to the deaerator into the automatic pressure regulating valve, check deaerator temperature of not more than 4.26 ℃ / min, deaerator pressure gradually rose to 0.147MPa. (7) auxiliary steam heating process, the water level should be controlled deaerator, vacuum is not established as the condenser, the overflow inhibited from opening, the electric drainage valve to the condenser. (8) the condensate system startup, if necessary, administered deaerator water level adjustment automatically. (9) when the four pumping pressure reaches 0.147MPa, check oxygen pressure, the water level is normal, open to four extraction electric valve deaerator, the deaerator cut four auxiliary steam for the steam extraction, auxiliary steam to the deaerator pressure regulating valve is closed, the deaerator by the constant pressure operation becomes sliding pressure operation. (10) when the extraction four electric valve check valve has been opened, four extraction check valve to the deaerator before the electric air trap closed. (11) continuously adjusting the electric door exhaust deaerator feed water under oxygen. 3, how the boiler deaerator outage (1) when the load is less than 20% of the rated load, the four drawers deaerator steam heating switching supplemented to maintain constant pressure operation 0.147MPa. (2) When the generator is stopped, as the case may decide whether to stop the deaerator Sheung. (3) If the outage deaerator more than two months, it should be used to protect the nitrogen, cut off all the steam source, water, water tanks exhausted than water, close the drain valve, the isolation comprehensive total nitrogen door open doors and isolation of deaerator nitrogen and maintain a certain pressure.

Affect the operation of the vacuum low pressure vacuum boiler vacuum boiler of the four factors mainly used for civilian heating, mainly used in residential, home, hotels and other densely populated places, but there are always some of the equipment has been hampered its effectiveness, not so warm, the following tell you about the factors that affect the operation of the device: 1, boiler and valves, meters there is no leak, there are currently includes inlet valve and instrument can guarantee no leakage occurs within 3 years. 2, the load can not have the mutation, changing the boiler load is normal for the boiler, the boiler can meet the general load regulation thirty percent to ninety-nine percent. 3, vacuum pump, three-way solenoid valve is working properly, since the vacuum pump, three-way solenoid valve is not run frequently, imported and seizure operation also prone to failure. 4, control whether or part failure, boiler controls and negative pressure, pressure controller can also occur in the operation of the failure is inevitable, such as the failure rate is even higher domestic controller. 5, the control section airtightness of the boiler should check whether the normal vacuum pump, the three-way solenoid valve is normal, check load changes, if the check is normal and negative pressure controller settings. 6, after everything is normal vacuum degree of recovery boilers still function properly, or to check all aspects of the maintenance shutdown. The actual operation of the vacuum boiler breakdown maintenance rate is higher than the pressurized steam boiler, a steam boiler control requirements than. Vacuum is the main indicators of the stability of the vacuum boiler, it is generally not hot equipment, it is ineffective this is a problem, if we find a problem we should immediately go to repair, to spend the winter cold to make themselves warm as soon as possible device.

First Affiliated Hospital of Bengbu Medical College, responsible for staff to feedback to our company, this low pressure vacuum boiler to use less smoke production, in line with the special requirements of the hospital surroundings and national requirements for flue gas emissions.

Ezhou Fuel Gas Vertical Horizontal pressure hot water low pressure vacuum boiler cost pressure hot water boiler in the course of our brand in the purchase, will meet technical doubts. Here, the authors say the same about you. Pressure hot water boiler pressure hot water boiler expense of the cost of the machine, burner costs and random (vacuum pumps, instrumentation, valves) the cost thereof. Cost factors constituting pressure boiler water, comprising an effective use where: mutually different name, manufacturer, manufacturing process, testing, design, selection of steel and the like. Among the very most important but also factors such as the following: (i) production plant productivity manufacturers of productivity, largely composed, good or bad of goods. Because, there is a productive unit, remove occupied relatively large number of components on the market, accounting for the full experience. Outside, and secondly, professional strength product design capability. Compete, with the ability to directly influence the design strength of the quality of goods is enormous. Affected, the choice of goods to Japan stability, energy savings, reliability, and good level of operation. The quality of the criteria for the selection of steel 2. steel, manufactured goods is the starting point. Legal standard steel, is to ensure that the degree of sealing pressure hot water boiler stable efficacy. Not up to standard terms and circumstances of steel, will cause pressure hot water boiler of goods, poor stability, high energy consumption, in addition to having a reliable danger, and operators mainly the choice of many second-tier brands, although provinces have enough time Jian costs, but worth the candle. ③. The degree of automation of manufacturing production sequence pressure hot water boiler, mutilation, plate bending, cutting, still very most important processes. These three processes, compared to workers to operate, the use of automated production capacity, is the best highlights significant. Production by ISO, with a higher accuracy, a very small fault. It is also, pressure hot water boiler big name goods, better than the name of a small key incentive. Because, manufacturing return, then more power fitting design capabilities, better get with the standard settings. ⑷. The step of detecting the part of the domestic manufacturers will not have an elaborate pressure hot water boiler goods, factory testing process. Pressure is complete, even if for legitimate goods. This is definitely working methods extremely irresponsible. Valid detection step requires Baoyun: test load, test inert gas, the welding seam is detected, detecting the degree of sealing, and the test run. Can be neglected, even-handed. It must be so, to ensure that operators have a grasp of legal goods, so that operators use the time to Japan, to prevent non-compliance with standards of goods produced, directly affect the normal production and business activities of the operators. V. 70% of the quality of service of second-tier brands, there will be no after-sales service. Service is entrusted to act as agent. But 70% of the agency, and no professional standards of the strength of the team. After the produce does not meet the criteria, it will have non-stop passing the buck, and the results can not be resolved. In summary, summarized as, pressure hot water boiler cost factors directly affected. Generally speaking, good, good goods bearing the cost of hot water boilers, pressure hot water boiler plus native burner, usually, 700KW, 10 million or so.
