oxygen trimming device for boiler

We learned that recently, Beijing issued a "three-year action plan to win the Beijing Blue Sky Wars," to date, mainly to strengthen ecological environment construction, pollution control tough fight to win Beijing, make the appropriate efforts. Details are as follows.

First, build a green energy system

Combined with the characteristics of the capital, in the city to protect the power supply, heat supply network under the premise of safe operation, relying on intelligent technology, strengthen external power transferred, increase the proportion of outside transmission. Full development of new local energy resources. Promoting clean renewable energy for heating, Municipal Development and Reform Commission, City Management Committee and other sector organizations to increase renewable energy use in key areas clean city sub-center, Beijing's new airport and other heating. In principle, to new natural gas cogeneration and gas chemical projects.

Second, lay Yajian coal finale

Led by the Agriculture Commission, in accordance with the principle of progressive advance of the first plains, mountains and then to "coal to electricity," the main scientific technical route choice, according to local conditions to promote rural village "coal to clean energy" work. 2018, the completion of the plains 450 villages "coal to clean energy" to carry out energy-saving synchronous rural residence. Completion of Pinggu District, clean energy transformation of coal-fired central heating boilers 5 of Yanqing district, the basic realization of the city's Plains "No Coal." In 2019, the development of scientific and effective mountains "coal to clean energy" technology roadmap, the heating period to break a long, large temperature difference and other problems, an orderly mountain villages of "coal to clean energy" work.

Third, improve energy efficiency

Municipal Development and Reform Commission and other departments to study and improve energy consumption limits system. City Housing and Urban Construction Commission, the Municipal Planning and Land Committee and other departments to revise new residential building energy efficiency design standards, energy-saving rate of more than 80%; accelerate the development of ultra-low energy buildings, new buildings strict implementation of green building standards. City Housing and Urban Construction Commission, the Municipal Urban Management Commission, Agriculture Commission and other departments saving renovations to existing buildings, Rural public buildings energy-saving standards and scope of the earthquake.

Fourth, accelerate infrastructure construction clean energy

City Management Committee, the Agriculture Commission and other departments to speed up the "coal to electricity" grid upgrading in rural areas, to meet the heating needs of the field of alternative energy. Into the "No Coal" facilities construction village, power and other reconstruction within the scope of planning in advance to give priority to implementation. Related power companies continue to strengthen the construction of power facilities and support capabilities.

place, it only needs the oil and electricity, then can be put into

operation. The boiler is coaled by a chain grate and equipped with a drum,

And how to determine what is alkalinity oxygen trimming device for boiler water cold room? For boilers alkalinity should be how to determine the appropriate scope? How to determine whether the boiler pressure boiler? And a cold water chamber fluidized bed boiler, specifically what? The three above-mentioned problems are associated with the boiler, and is also very important. So, then, without further ado, to answer specifically, so that we can understand and grasp. 1. boiler alkalinity should be how to determine the appropriate scope? On the boiler, it is necessary to have a certain boiler water alkalinity, the specific reason is because to avoid boiler scale, and silicate scale, so as to avoid some of the problems, and to facilitate their normal work and run. In the specific range thereof, the upper and lower limits, for 6mmol / l. In the upper limit, it is generally of 8mmol / l, so as to avoid corrosion and alkaline caustic embrittlement occurs boiler.

Greenhouses have very strict requirements of humidity and temperature control, which directly affect the the plants growth and earnings. Zhengzhou Boiler Co., Ltd has a long history of providing high efficient and reliableoxygen trimming device for boilers for thegreenhouseowners that demand uninterrupted service when it comes to their domestic water and hydronic heating needs.

Design Specification For Boiler Control System
