Recently, Xi'an, Shaanxi Province take minus coal, train control, dust suppression, government sources, prohibiting other measures, the air pollution caused by human factors reduced to very low, efforts to improve air quality in Xi'an winter. As of early November, Xi'an has cut 100 million tons of coal-fired, 15 high-ranked companies relocate or shut down.
In 2018, the Shaanxi provincial government issued a formal mandate to inform, Xi'an total of 140 million tons of coal to reduce the task, mainly around the Xi'an city government to cut electricity, central heating boilers Chaigai, urban and rural residents scattered coal and gas supply security in four areas of governance to carry out jobs. As of the end of October this year, has cut coal 1.015 million tons, completed 70.7% year plan. Built area of 29,419 catering units are the use of clean energy, outside built-up area 5196 catering units are to switch to clean energy.
Vehicle exhaust is one of the sources of atmospheric pollution. In order to strictly control the "black tail", environmental management staff at the three-ring along the line, passenger stations, farmers market, food stores and other black smoke high incidence of vehicle checkpoints set up 423-bit, low-speed vehicles investigated a total of 71,300 cases to go cut the line , black smoke car 7027 cases.
In the "anti-summer period", Xi'an continue to implement the motor vehicle limit line of control measures, and completed the 3255 update of pure electric buses put into operation, the completion rate of 102%. Newly started construction of public parking spaces 12,908, 86.1% completion rate. Investigate ChaoBiaoChe 3504.
In terms of the source rule, Xi'an cumulative Mopai "scattered dirt" Enterprise 21021 (including New West Ham), complete renovation 8163, completion rate of 38.8%; 15 high energy consumption, high emission enterprises to complete the relocation or shut down; 3399 Taiwan low nitrogen gas boiler to complete the transformation, the completion rate of 99.4%.

In terms of prohibiting, Xi'an completed summer crop straw comprehensive utilization area of 249.82 acres of mechanization, comprehensive utilization rate of 95.4%, exceeding the target task. At the same time, organized and implemented six acres and nine provincial and municipal straw utilization demonstration projects, compared with the provincial target increase of 12.5 percentage points; investigate and deal with the problem of black smoke burning from 457; 8 consecutive years of summer and autumn straw Jinshao to achieve "zero fire point" goal.
This year, the Xi'an handled a number of prominent air pollution problems. City of iron-fisted rule examination revealed a total haze to do all kinds of air pollution problems 1862, the city set up a team of 153 people to strengthen the supervision and inspection found problems common enterprise 6128, cross-check inspection found a total of 11,781 business problems. These issues are issued under the supervision of the list of issues to be reform.
Gas-fired 2ton diesel steam boiler abnormal situation, how should we deal with it? When we use gas steam boiler, failure or abnormal phenomena it is inevitable, but in order not to affect the normal use, in the event of a problem gas steam boiler to be timely processing solutions, then the face of all kinds of circumstances, we should how to handle it? Share some of the ways we deal with unusual circumstances. If only gas steam boiler circulating pump abnormalities, such as its current decreases, the pump outlet pressure back to zero, which indicates no oil pump is idle, it may be caused by oil vaporization. Yang identify the reasons therefore first vaporized measures; such as clogging of the filter circulating pump bypass opening evacuated immediately clean the filter; heat transfer fluid as a result of added aqueous or decomposed gases are not excluded in the system, should immediately open the vent an exhaust valve. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, stainless steel chain should be cleaned. If the gas steam boiler before and after the filter increased in pressure, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. In addition to its low furnace outlet temperature liquid phase heat carrier, mainly for lack of heat fouling problems, it is timely soot blowing. Gas steam boiler grate more common problem is stuck, there are reasons including breaking grate or the grate off loose pins; coal grate has stuck to metallic inclusions; arched grate; slag is sinking the tip of the grate stuck. In response to this phenomenon, the required reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. But also to re-adjust the adjustment screw on both sides of the grate tension, if still does not work, we need to replace the sprocket.
The main factors affecting small type gas 2ton diesel steam boiler steam boiler thermal stability of gas ignition is not difficult to establish a stable small fire signal, the root cause is a small fire detectors can not detect normal to the fire. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees biomass boilers categories: biomass boilers horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Small fire detectors use the ionization fire detection, and requires effective contact area of the flame, the flame stability and proper size, the gas pressure must be controlled within a very strict range. If the ignition gas pressure is too high, too long a small fire flame is moved beyond the detection range of the small fire detection probe, the system will not be mistaken for a small fire; if the gas pressure is too small, the gas will be firing too small and the boiler the blast very, very easy to blow out the flame, the ignition is not possible. Also, fire gases found a small pressure regulator valve regulating performance is not good, fine adjustment can not be achieved. Stability is also related to a small fire and the ratio of the size of the boiler furnace pressure boiler feed valve. The damper is too large or too small can affect the stability of the flame is ignited and the flame, furnace pressure will lead to extinguish the flame. In order to ensure the accuracy of fire detection, fire detection, we can adjust the small depth of insertion of the probe, the position of the fire detection probe in the correct position, in order to more effectively detect small fires flame.
Two of the three types of protection devices What is the difference of fuel vapor 2ton diesel steam boilers and boiler fuel gas steam boiler steam boiler fuel for steam boilers, steam boilers or fuel oil-fired boiler is in, no matter which argument, are refers to this kind of boiler fuel steam boiler. 1. the type of fuel steam boiler fuel steam boiler, which in general, can be divided into both established and horizontal. Vertical fuel steam boiler: the combustion engine, generally use the set in this manner, and using two-pass configuration, so that complete combustion can be performed. In addition, the use of these forms, the stability of the operation of the boiler, it is also very beneficial. The advantages of vertical steam boiler fuel, mainly for high thermal efficiency, and can reduce costs. Horizontal fuel steam boiler: the structure, using a three-pass tube pyrotechnic this configuration, pressurized combustion chamber so that combustion, thereby reducing the combustion load, and reduce exhaust gas temperature. As a result, promote energy conservation, economic performance of the boiler. Further, since the waveform of threaded pipe and furnace thermal efficiency of the boiler can be remarkably improved, and the use of time can be increased. 2. The fuel vapor pressure protection boiler controller: generally this type of high sensitivity, is mainly Zidongkongzhi or chain protection. And may be adjusted according to actual operating pressure of the boiler, so that appropriate. Flame protection: in the main burner, a flame failure protection devices. Its role is the amount of fuel steam boiler combustion is detected, when abnormal combustion, can take immediate steps to make the boiler stopped working in order to avoid some of the adverse consequences. Self-locking power failure protection: Usually burst power for this case the use of the protective device, so that when a sudden power failure, the fuel steam boilers can immediately shutdown and self-locking. Note, however, that when power is restored, the boiler will not start on its own, it must be reset after unlock, boiler to start the ignition and start working. Fuel gas steam boiler and the steam boiler distinction fuel gas steam boiler and a steam boiler, as energy saving device belong to the combustion products of carbon dioxide and water, will not pollute the environment. Oil-fired boiler and gas boiler biggest difference is the use of different fuels, gas boilers use natural gas, city gas as the fuel, light oil, heavy oil-fired boiler is used as fuel. In contrast gas boilers, boiler fuel cost is much higher than gas boilers, therefore, those commonly used in the oil-fired boiler operating conditions of enterprises do not have a gas boiler or Shiyedanwei use. The difference between the fuel and gas steam boiler steam boiler: 1, fuel different: the former light oil, heavy oil as a fuel, which uses natural gas, city gas, liquefied petroleum gas as fuel. 2, the burner different: the former use of oil burners, gas burners later use. 3, different cost: the former high cost, about 1-2 times the cost of the latter. The same point of the fuel gas steam boiler and a steam boiler: 1, the same boiler: the same tonnage same steam boiler or hot water boiler of the boiler body. 2, the same auxiliary components: in addition to the burner, auxiliary oil-fired boiler and gas boiler accessories equivalent tonnage same. 3, the same production process: The process of production and processing were carried out in accordance with the same process and production standards.Free Chat
