This type of boiler without the use of a condenser, the condensate can be achieved within the furnace, exhaust gas temperature can drop below 50 ℃, the thermal efficiency can be improved compared with ordinary condensing boiler reaches 10% or more as compared to 104%, down to a one-year, may be save a lot of fuel input costs. Furnace using food-grade enamel coating, can meet the standard of drinking water safer and more reliable. 6, a vacuum ultra-low emissions gas hot water boiler (T6)

How water steam boilers operate normally do? Steam boiler design are generally employed in three return, wet back, eccentric furnace, boiler structural asymmetry in different forms will have its own unique characteristics and operating modes. It has its own certain operating principle. Some recent abnormal weather, snow days is not haze, then, in this weather, water steam boiler how to run it properly? Water steam boiler and a double pipe with a single tube, is usually the case. And the suction pressure of several type, the more suction applied single-tube, by the housing, the steam nozzle, water nozzle, check pad, the exit nozzle and the mixing nozzle of several components. Simple injection operation, facilitating means. Suction head of 2 meters, temperature does not exceed 40 ℃. When need to open the first water steam boiler steam valve a little, so that a small amount of water vapor into the device, vapor discharged from the nozzle, near the mouth of the vapor with the vapor into the air, with the overflow discharge valve, a vacuum is formed within the water, a water tank by atmospheric pressure by the suction pipe into the water injector. Increase the degree of opening of the steam valve, large amounts of steam into the mix mixing mouth with water. Mixed water vapor kinetic energy obtained at high speed into the nozzle. Since the nozzle diameter is gradually expanded, mixed water to slow down, the pressure increased to greater than the pressure within the drum, the drum into the valve open. Steam boiler at the same time we must pay attention to it on a regular basis take care of themselves. These are the processes related to operation of steam boilers small series to introduce you in the operation of the water injector and methods.

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.

After years of efforts, the overall governance of Beijing's total coal consumption has achieved initial results. By the end of 2017, all of the total coal consumption of 4.85 million tons, accounting for only 5.6% of the city's total coal consumption, coal-fired completed three years ahead of "Thirteen Five" energy development plan period proposed control in less than five million tons The goal.

By 2013 to 2017 for five consecutive years to promote the work Yajian coal, Beijing successfully completed the first phase of the "Yajian based" Yajian coal work, go to "run mainly to protect", established clean energy use long-term mechanism to combat second phase coal-fired rebound. Beijing's total coal consumption in the future will be long-term control in less than 4.2 million tons, coal is mainly used for urban hazardous waste incineration, energy and protect the city safe operation of remote mountain villages Beijing winter heating three aspects.

As of last heating season, heating central heating proportion of clean energy in Beijing has reached 98%, in addition to parts of Pinggu and Yanqing, Miyun three zones as well as six coal-fired heating boiler room, other regions have achieved heating boilers no Coal.

This year, Beijing will complete the rural village 450 villages, the villagers coal public spaces and 53,000 square meters of agricultural facilities Zizhong change clean energy work, and strive to complete the Yanqing east of central heating central heating fuel in pre-season coal boiler clean energy transformation, in an orderly coal-fired heating center south of Yanqing, Pinggu Riverside, Xinggu, Miyun Taishi Tuen urban and non-built-up areas boiler clean energy transformation.

In addition, this year, Beijing Yanshan Petrochemical Industries will start coal-fired facilities clean energy transformation, and continue to consolidate six districts of the city, the southern plains "No Coal" results have been achieved on the area of ​​clean energy transformation, embargo, ban, ban save bulk coal, to prevent rebound.

Speed ​​up the construction of clean energy facilities, Beijing will work to enhance the rural town of Plains gas pipeline network construction, improve rural consumption of clean energy supply security capacity, promote Plains natural gas pipeline "through town." In the gas network facilities are relatively weak areas, speed up the liquefied natural gas, compressed natural gas supply facilities, increase the supply capacity of natural gas distribution in rural areas. At the same time, we continue to promote the 2018 "from coal to gas," "coal to electricity" supporting gas engineering and construction of power transmission project, to meet the full 2018-- coal to clean energy by 2019 energy demand for the heating season.
