industrial gas fired 0 5 ton vacuum boilers factory

Affect the operation of the vacuum industrial fired 0 5 ton vacuum boilers factory 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.

Boiler oxygen equipment startup and shutdown procedures, processes 1, check before starting industrial fired 0 5 ton vacuum boilers factory 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.

Recently, we learned, Zhangbei County, Hebei Province to speed up the transformation of low-nitrogen combustion, gas-fired, Zhangbei County Environmental Protection Agency issued the "Notice on nitrogen oxide gas industrial fired 0 5 ton vacuum boilers factory governance", the transformation of the way around the gas boiler, the transformation of technology formalities to conduct a comprehensive explanation of propaganda, mobilization of Zhangbei above a certain size gas boiler units to actively participate in low-nitrogen transformation.

In order to ensure the smooth progress of work, the EPA developed a grasp of leadership, and a series of regular briefings on the system, arrange for the transformation of real-time tracking progress, personally led by the leaders in charge of the transformation of the construction-site supervision, to solve various problems during installation accelerate the transformation progress of the project. To date, more than 10 tons of steam Zhangbei natural gas boilers have been completed the transformation and detection of nitrogen oxide emissions, emission concentration all the stabilizing reached 30mg / m³ or less, over-done.

To protect the subsequent reconstruction work in depth, Zhangbei County township organization, the relevant units of the county with a comprehensive Mo Pai, gas-fired, gas-fired boilers for each specific model boiler unit, whether used and other basic information has been verified, the establishment improve the work ledger; to ensure that the base number is accurate, targeted work, Zhangbei arrange strengthen docking with the gas company, promptly verify the perfect new gas boiler archives, ensure the follow-up task of transformation clear, exhaustive renovation project. At the same time, combined with the actual development of the Zhangbei gas boiler compliance programs to lay a solid foundation for the comprehensive promotion of this work next year.

In the use of vacuum gas industrial fired 0 5 ton vacuum boilers factory, need to understand what matters vacuum gas boiler also needs to complete its operation in accordance with the guidelines in the use of gas boiler using a vacuum today's increasingly wide following for us to come together to figure out the vacuum gas boiler in the selection as are those who need to understand the summary. First, employees need to understand the use of vacuum gas boiler quality employees use vacuum gas boiler need for quality vacuum gas boiler outstanding figure out, and I too understand the safety rules that are part of the employee does not belong to the unit is not operating, on the way transfer classes also need to do the transfer of records. Second, the gas detection engine vacuum boiler needs to be done before launching also detected in various fields, for example, looked at gas load value is not normal, vacuum gas boiler is not possible through routine gas, followed by the pump is not in normal use, etc., these are all employees need to use the contents of the intentions of detection. If the use of employees exposed to failure, also need to reach accurate disposal, failing that can easily lead to serious danger, the company's employees can also use time and counseling to improve the professionalism of the staff in the use of vacuum gas boiler start.
