horizontal multi tube steam boiler startup procedure

Pressure hot water boiler does not use softened water, what harm? Boiler during operation of the water quality requirements are more stringent, thus making boiler feed water, will install water softening water treatment device, then, if not water by softening what harm it? 1. waste fuel because the water is not timely treatment, over time, the water content of non-compliance with the boilers physical or chemical reaction, can cause damage to the boiler wall or boiler scaling, thermal insulation effect and impact of the boiler efficiency, in order to ensure that this part of the loss, the amount of fuel will increase with. 2. there will be corrosion. Since the acid-base substance and oxygen present in the water with the metal body of the boiler should chemical method, so that the furnace wall is gradually reduced, dents, reducing the strength of the boiler, can easily cause accidents operation. Of course there will be other hazards, such as boiler output, normal boiler water cycle, boiler shortened life expectancy and so on. These are the dangers of not using soft water changes caused. After analysis of the dangers of not boiler water softening treatment, you will find, if you want, such as the boiler low-power high efficiency, high operational safety, water softening boiler also make one of the most important factors, therefore, strictly according to the standard treatment also needs to be carefully done.

What are the advantages of condensing boilers? As China's energy optimization, and constantly promote the implementation of energy conservation policies, use of condensing boilers to improve the utilization of natural gas, use the remaining heat to increase heat production and the way of life has become an important means of energy re-use of the moment. As a result, the market also appeared condensing boilers more and more popular around the world, then the number of boilers, condensing boilers which have particular advantages making it the choice for the majority of consumers do? Condensing heat exchanger 1. Optional use of stable material. High-heat converter material requirements condensing boiler used, so it has a strong corrosion resistance. Since the smoke emission will contain large quantities of carbon dioxide and other acid gases, when converted into the flue gas when the condensed water will have varying degrees of acidity, the conventional switch with long-term exposure can cause condensate corrosion scratch off the surface, and changing condensing boilers converter is used to produce high-quality and stable material, reduce corrosion damage to components and zengcheng time. 2. high energy efficiency condensing boiler. Condensing boiler internal cryogenic fluid temperature can reach a very low level, and to take away the effect of reducing the flue gas is excellent, also increases the water vapor condensate can be recovered in the heat and latent heat is also more and more, thereby condense values ​​using thermal energy efficiency of the boiler is larger. 3. Good environmental benefits. Gases such as carbon dioxide and sulfur dioxide produced after the combustion fumes have serious environmental pollution, in particular, the discharge capacity is small low boiler efficiency of various contaminants stresses can cause serious environmental problems. After installation through condensing boiler, the flue gas water vapor is condensed, when many contaminants dissolved in water condensed on the flue gas purification emissions, while secondary treatment for condensed water can be completely non-polluting emission. In summary, the advantages of condensing boilers includes not only stable and reliable starting performance, but also including the use of equipment has great effect on the energy saving and environmental protection. Condensing boiler will use the moment with the State Government's strong emphasis on the concept of environmental protection has gradually up wide, which the market can provide high-quality manufacturers of condensing boilers shelf increasing, consumers want to use a condensing boiler has the best quality of work We need to learn to distinguish their brands and equipment manufacturers.

Fast boiler is committed to the development and manufacture of clean fuel boilers more than 20 years, annual investment of more than 5% of turnover on research and development of new technologies and new products; and production technology, enterprise system, workshop management have formed a relatively complete system and accumulated a rich experience, has become a priority choice for customers in mind.

All along, Zhangjiakou City, Hebei Province, took the central environmental protection supervision "look back" as the main problem of feedback opportunities to enhance the ecological environmental protection, pollution prevention and fight tough fight, active rectification, hard to rectify, resolute reform, promote the environmental reform task completed on schedule. We understand that in 2018, Zhangjiakou City Daly to promote projects cut coal, the accelerated clean alternative to coal consumption year on year in 2017 to reduce 1.04 million tons.

For unfinished "2017, the province's energy cut carbon coal down the main points of" cut annual coal requirements of mission objectives problem, Zhangjiakou City, supervisors coal companies cut coal, high quality coal, strengthen energy-saving technological transformation, to fully grasp the total coal consumption control and reduction of bulk coal.

The strengthening of key coal enterprises cut coal, to promote energy-saving technological transformation projects, several key coal enterprises to continuously improve energy standards. And vigorously promote the project minus coal, coal production in 2018 to defuse 8.6 million tons, out of coal-fired boilers 1663 units. Accelerate clean coal alternative, clean winter heating selected pilot cities in northern, rural complete "electricity instead of coal", "substitution of gas for coal" 6971. And vigorously develop renewable energy sources, as of 2018 the city's renewable energy installed capacity of 13,454,800 kilowatts, accounting for 74.2% of all electricity installed capacity, the highest in the country.
