National Day holiday just ended, Shenyang Environmental Protection Bureau threw himself into the urban environment construction. Before the onset of winter, the Shenyang municipal government will strictly control the air pollution problem. It is reported that Shenyang Environmental Protection Bureau issued out since November 1, Shenyang will strictly enforce the standards of air pollutants emission limits in particular, all the environmental standards of heating enterprises will be cleared out of the heating market.

Shenyang Environmental Protection Bureau issued "on the thermal power industry, coal-fired boilers execution of air pollutants in particular emission limits of the notice" in the next year (the "Notice") requires: Thermal power within the gamut of Shenyang, iron and steel, petrochemical industry and fuel emissions of air pollutants in coal boiler project "thirteen five" period should implement special emission limit standards.

Shenyang is also a good environmental citizen blue sky, Shenyang City this winter and will continue to adhere to "turn point furnace, load shifting blocked arteries," the implementation of standards. After heating units gradually open blocked arteries, Municipal Environmental Protection Bureau will strengthen the routine inspection of law enforcement, and pay close attention to on-line monitoring data 474 coal-fired boilers, boiler emissions of non-compliance immediately ordered to carry out rectification, and severely dealt with strictly waste-water treatment, ultra row of such acts. At the same time, the Shenyang municipal government will also heating units regularly conduct random sampling of coal quality.

It is understood, Shenyang open blocked arteries in succession since October 26 from heating. To ensure that excessive heat stable and safe operation standards, Shenyang will be fully commissioning of heating facilities, to solve problems in a timely manner to ensure the November 1 time blocked arteries heating, the temperature reaches above 18 ℃. After the blocked arteries, Shenyang will strictly implement the winter heating emergency plans to complete the repair within 6 hours general accident, complete repairs within 24 hours more accidents.

Shenyang Environmental Protection Bureau official says, the environmental protection department will be heating business day on-line monitoring, and strictly control their emissions of air pollutants. Over the years, Shenyang has been doing the heating business "remove small and large," the relevant measures, so that some can not afford to increase environmental protection facilities of small companies to large companies merge powerful, let Shenyang municipal heating more environmentally friendly. Strict implementation of the special emission limits of air pollutants standards, both national policy, but also the heating of corporate responsibility, companies must increase investment in environmental protection to ensure the discharge standards.

It is understood that this year, the Shenyang municipal heating will continue to increase the proportion of clean energy, clean coal existing store 230,000 tons, an increase of 30,000 tons last year. Shenyang City, natural gas and other clean energy heating an area of ​​150 million square meters, clean heating the proportion reached 45%, up 6% over last year. Reduction of 1 million tons of total coal year, 5000 tons of coal-fired boilers to complete denitrification, the city starting from November 1 particularly strict implementation of air pollutants emission limits.

Pressure fire operations and precautions Henan fast boiler's steam boiler Xiao Bian told you about the operation of steam boilers and pressure fire precautions and stainless steel high temperature magnetic pump structural characteristics 1. pressure steam boiler fire steps of (1) to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. (2) to the slag is thickened seam about 1 mm from the stop grate rotation, the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal the lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the coal-fired back, a distance. (3) the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, can be restored run. 2. Note the use of a steam boiler (1) before starting Check power supply voltage, there are unusual circumstances water, close the drain valve opens the water supply valve, check whether the pump stuck, stuck if the pump, remove the fan cover, rotation of the motor shaft to the flexible state to boot. (2) When the steam boiler maintenance or replacement of parts, turn off the power to avoid live work dangerous. (3) electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean. (4) steam boilers in accordance with quality requirements, when using the apparatus sure to install a water softener, the water softener is not used because the boiler may cause fouling, may cause serious squib, shortening the life of the boiler. (5) Please note that when using sewage. And at least once a day with a discharge pressure of between 0.1MPa to 0.15MPa discharge may be prevented clogging of pipes, sewage should be properly connected, to guard against burns. Stainless steel high temperature magnetic pump structural features: a sliding bearing magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. Because of engineering ceramics has good heat resistance, corrosion resistance, abrasion performance, so the sliding bearing magnetic pump more use of engineering ceramics production. Because of engineering ceramics are brittle and expansion coefficient, so the bearing clearance is not too small, so as not to hold the shaft accident. Since the magnetic pump in order to lubricate sliding bearing medium conveyed, it should be used depending on the medium and conditions, making use of different materials bearing. 2. Cooling lubricating fluid flow control pump operation must be flush cooling internal friction annulus region between the sliding bearing and the magnetic rotor and the containment shell with a small amount of liquid. Coolant flow rate is typically 2-3% of the design flow of the pump, the annulus area between the inner magnetic rotor of the eddy current generated spacer bush high heat. When enough cooling lubricant or flushing holes poor, clogging, the medium will result in a temperature above the operating temperature of the permanent magnet, the inner magnetic rotor gradually loses its magnetism, the magnetic force actuator failure. When the medium is water or water-based liquid, the temperature rise can be maintained in the annulus region of 3-5 deg.] C; or when the medium is a hydrocarbon oil, allows the annulus region of the temperature was maintained at 5-8 ℃.
