Continue to promote the comprehensive management of dust pollution, coal-fired pollution control to strengthen and deepen the industrial pollution control and related fields, etc., which are from governance "Xining City 2018 air pollution comprehensive management action plan." Xining City, the official launch of construction on the "Xining blue" and maintain the action. Aspects of dust, industrial pollution, coal pollution will increase management and control, to develop specific control measures for building a better Xining efforts.

Since the launching of "Xining blue" action in the coal-fired pollution control, Xining City has accumulated more than 3,000 tons of steam "coal to gas," the task of governance, the main city of the city "coal to gas" campaign to take the lead. With the further implementation of the Blue Sky Project, Xining substantial increase in utilization of clean energy, significantly improve air quality of the environment, it has been among the five northwestern provinces in the forefront of the capital city.

Taking into account the special Xining City, Qinghai-Tibet Plateau is located in the geographical location, the winter heating season is longer, coal dust is an important source of winter air pollution, while heating pipeline dredge more difficult, the implementation of the transformation plan will face difficulties pipeline reconstruction. To effectively improve urban air quality since 2013, Xining City, carry out a comprehensive "coal to gas" governance by supporting comprehensive measures upgrading natural gas pipeline network, such as the yellow car out of standard co-ordinate the promotion of winter clean, safe and efficient heating, achieved within the natural gas pipeline network coverage coal to gas works full coverage.

To promote the implementation of clean energy projects, Xining City, expand the scope of the ban on coal to 166 square kilometers, and implementation of the "coal to gas" in the natural gas pipeline network range, achieved in the area of ​​coal-fired boiler "cleared." Increase coal trading market will be rectified, completed a five coal market and coal two 49 business outlets, effectively reducing the use of inferior coal pollution on the surrounding environment.

How to guarantee steam quality of steam boiler

Steam boilers are much more widely used than hot water boilers. Hot water boilers are mainly used for heating and providing hot water supply, while steam boilers cover all industries such as industrial and power generation. What are the requirements for boiler boilers for boiler boilers? Undoubtedly safe, stable, efficient, long service life, cost savings, etc., however, these requirements are indirectly or directly related to steam quality. The quality of steam is critical because it affects the stability, reliability and economy of the system, as well as product quality, production power and energy consumption. If the steam boiler user does not pay attention to this, it will definitely lead to a series of follow-up problems for the boiler.

1) Cleanliness: There are rust and carbonate deposits in the steam pipeline, and there may be slag and sealant fragments remaining in the equipment. These impurities may cause jamming and damage to the valves and equipment, and also increase the wear of the pipeline. The way to improve cleanliness is to install a pipe filter, and the filter should be horizontal.

2) Dryness: Incorrect water treatment of boiler hydration, unreasonable boiler level control, and short-term high peak load and other factors will cause the boiler to co-exit the boiler, so that the boiler outlet carries boiler water. When steam is moving in the pipeline, heat dissipation from the pipeline condenses a portion of the steam, adding condensate from the pipeline. The chemical substances and other impurities carried in the condensed water will accumulate on the surface of the heat exchange equipment, affecting the power of the heat exchange equipment, and the accumulated impurities will be fouled on the metal surface of the equipment, resulting in uneven heating of the metal surface and shortened life. In addition, the presence of moisture in the vapor reduces the transpiration of the steam, adding steam consumption; the moisture in the steam will increase the thickness of the water film measured by the heat of the heat transfer, and the rated heat transfer resistance occurs. The addition of a steam separator is a useful way to improve steam dryness, and an efficient steam separator can increase steam dryness to 98%.

3) Purity: There is air in the steam system because the steam that is generated by the boiler still inevitably contains a small amount of air, and there are also air when the pipes and equipment are started. When the system and equipment are shut down, the air is taken in due to the internal vacuum. The air has a very low thermal conductivity and is a poor conductor for heating. The inclusion of air in the steam system will reduce the production capacity of the steam equipment and will also increase the corrosion of pipes, valves and equipment. The most useful way to eliminate non-condensable gases such as air in a steam system and thereby improve the purity of the steam is to install an automatic air venting device in the system.

4) Pressure/temperature stability: In order to ensure process heating requirements, the steam pressure at the steam point should reach the demand value. Together, the steam pressure should not be too high, otherwise steam consumption will be added.

Here's a look at what the characteristics of the vacuum boiler. 1, the internal structure will not corrode due to the vacuum boiler negative pressure vacuum state, it is completely isolated from atmospheric pressure, so the configuration of each unit boiler exhaust pump will continue to discharge the steam inside the unit, not within the organization structure caused by corrosion, so the vacuum phase transition boiler in terms of durability performance is quite good. 2, the different secure and normal pressure boilers, vacuum boiler air is evacuated children because the inner container forms a vacuum environment, so its use in the process of working in a vacuum furnace-like body is not generated due to heat expansion, but it does not belong to the pressure container, and therefore there is no risk of explosion.

What are the advantages of using vacuum boiler? Vacuum boiler is primarily a device for modern intelligent residential heating, are usually provided with heating and sanitary hot water heating in places such as commercial establishments and residential areas, the traditional use of heating equipment compared with high security performance so there is no danger of explosion, cracking and expansion so easy to hurt people's appearance. So, good quality vacuum boiler which has the advantages of using it? First, the vacuum boiler mainly take the form of a vacuum suction operation, whereby in use, excellent safety and case rupture boiler explosion does not occur, while the force of the vacuum boiler steel high pressure zone and high temperature zone to achieve successful separation, using when the boiler due to the action of the vacuum can be prevented damage to the equipment where high temperature and pressure occur and can extend the life of the device functions. Second, the overall configuration of the vacuum boiler design more scientific and rational, having a smaller overall footprint advantage whereby in use can greatly save area, and to implement vacuum boiler pan vivo heat exchange can effectively shorten the warm-up period, and reduce energy waste. Third, the vacuum boiler to take automatic intelligent control mode, can be realized when using unattended or remote intelligent network control can be used to manipulate the device, and the inside of the vacuum stainless steel boiler provided with a heat exchanger, so that no rust phenomenon and not pollute the water. Fourth, the vacuum boiler cf mainly take the form of indirect heating boiler, external heat exchanger and circulating water pump in the overall installation cost can save a large part, and the vacuum boiler also has a fast heating, heat transfer efficiency and good thereby saving features high fuel costs. Above is the advantage of using a good quality vacuum boiler has, for the cold winter season in terms of the need to provide heating or region, the choice of the best vacuum boiler used in a variety of different places use homes, schools and shopping malls, etc., not only to facilitate people to use heating and also has a strong safety.
