March 22 to 23, Ganzhou City, Jiangxi Province Bureau of Quality Supervision established party leadership team, the progress of the 2018 phase-out of coal-fired boilers to conduct random work. Leading group led by Liu Ping, deputy director of Ganzhou City, Municipal Quality Supervision Bureau, the Municipal Industry and Information Commission, the Municipal Environmental Protection Bureau and the Municipal Development and Reform Commission composed of four departments jointly checks group within Xinfeng County of Ganzhou City, Nankang District, Jiangxi counties and carried out spot checks Yudu County coal-fired boilers working-out of a total of 17 companies.
Sampling results show that 17 companies, more than 10 companies to complete phase-out of coal-fired boilers, the other seven unfinished business executives also said that this year will be to complete the rectification work before December 20.
In this sampling event, checks the group also proposed rectification direction of the coal-fired boilers for local authorities: by strengthening the policy advocacy, strengthening inter-site inspectors guidance and strengthen departmental interaction, the three parties work together to ensure the timely completion of this non-compliance within Ganzhou coal-fired boiler out of the task.
Vacuum condensing boiler vacuum boiler how much the price currently is not required filing examination, if the boiler factory stock, then, companies have used the site, it is smoothly approach quickly installed, run. For businesses, the choice of vacuum condensing boiler, be sure to go through many contrasts, so, can choose a more suitable plant boiler products. The choice of vacuum condensing boiler must be for manufacturers to have a detailed understanding of all aspects of quality, after all, a good brand of boiler manufacturers are guaranteed, therefore, for the enterprise, must be multifaceted comparison after selection, recently, there is a business to be fast boiler consulting, want to buy a vacuum condensing boiler, but for the specific need of models and prices do not understand, and I hope fast boiler technicians help accounting the technical staff according to the needs of the fast boiler hot water provided by the company, out of accounting data shows that the firm with a 2-ton vacuum condensing boiler is to meet production. The current price of the model boiler is around 150,000. Therefore, the company for the vacuum condensing boiler prices have detailed knowledge of.
Boiler oxygen equipment startup and shutdown procedures, processes 1, check before starting 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.
What are the characteristics of vacuum boilers?
Vacuum phase change boilers in the industry are usually referred to as vacuum boilers. Professional vacuum boilers form a negative pressure vacuum environment within the enclosed furnace body. There is no danger of expansion and explosion because a vacuum boiler creates a low-pressure environment with little air, and then uses water to boil at a low temperature to produce steam. As a result, it is now commonly used in higher elevations. Let's find out what the features of the vacuum boiler are.
1, the vacuum boiler will not corrode because the internal structure of the vacuum boiler is negative pressure vacuum state, so it is completely isolated from the atmospheric pressure, so the pump pumps configured by the various units of the boiler will continuously discharge the steam from the unit. It does not corrode the internal structure, so vacuum phase change boilers perform fairly well in terms of durability.
2, safety and reliability are different from ordinary atmospheric pressure boilers. Because vacuum boilers pump air out of the inner container to form a vacuum environment, the furnace body does not work under the vacuum body in the course of use and will not be expanded by heat. It is not a pressure vessel, so there is no risk of explosion. At the same time, if the pressure increases due to faults or other perceived factors, the vacuum pressure switch automatically cuts off the power supply, so vacuum boilers are more reliable than other types of boilers in terms of safety.
