We all know that boiler scaling will bring a variety of problems to the boiler, such as reducing the service life of the boiler, increasing unsafe factors, making the boiler metal brittle, virtually increasing maintenance costs, and so on. So we have to regularly clean the boiler maintenance. So what are the methods and techniques of Fangkuai boiler descaling? The editor will list for you one by one: first, the artificial scale removal method, loosening the bolts on the boiler sewage outlet is generally common at both ends of the boiler horizontal tube, and we can see the scale on the inner wall of the boiler horizontal tube. Then use a small shovel and other tools (no hard requirements, can remove the scale from the boiler and The scale is scraped off or shoveled off, then rinsed the inner wall with water to flush out the waste, but this method is more energy-consuming to our production staff, the second is chemical scaling, This is a convenient and quick method of scale removal, chemical descaling process: clean water washing boiler cleaning agent, clean water rinsing passivation treatment; Before cleaning, we should disconnect other systems that have nothing to do with the boiler, connect the cleaning tank, the cleaning pump and the boiler into a cleaning closed loop; rinse once with clear water, wash out the large particles of dirt, and then put in the scale remover for circulation cleaning Wash and decontaminate, the process is usually 2 hours, then rinse again, clean up the residue, put in the passivation agent, maintain. These are two methods used at present. For boiler scales, we can pay attention to the treatment of boiler water at ordinary times, specifically lime soda softening method. In the water to be put into the boiler, we can use lime soda soften water. Reduce the minerals it covers, or put chemicals into the boiler to soften the water.

What are the gas-fired boiler valve instrument, have any effect

In recent years, with the strengthening of China's environmental protection efforts, high low emissions, efforts to clean gas boiler gradually become the mainstream products on the market. However, to get gas boilers to maintain normal operation, there is more than boiler, but also supporting auxiliary equipment and instrumentation valves. Among them, the instrument is a major control the operating parameters of the boiler accessories, is very important.

February 20, 2019, the Beijing Municipal Government issued the "Beijing's pollution prevention campaign of 2019 Action Plan" (hereinafter referred to as the "Action Plan"). "Action Plan" clearly 2019 development goals: the first is the city PM2.5年均浓度, three-year moving average concentration strive to continue to decline.

Since 2018 autumn and winter, fog and haze in control efforts continue to increase. Beijing, Tianjin Fenwei Plain, the Yangtze River Delta region of the focus of supervision and maintain a high pressure situation, provinces and cities have also introduced Blue Sky Battle plan, air pollution control sector welcome the opportunity. And because the 2018 autumn and winter abolition of green "one size fits all", so that pollution from the administrative means to switch to environmentally friendly means to speed up environmental protection business orders release.

"Winning Blue Sky Battle three-year action plan" called for increased efforts to eliminate small coal-fired boilers, the county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers, in principle, to the new 35 per hour tons of steam coal-fired boilers. We believe that, under constant fog and haze, the small boiler phase-out process will accelerate. Research believes that by 2021 the transformation of coal-fired central heating investment 88.6 billion yuan, annual operating income of 240 billion yuan, the central heating market will also speed up the release with the environmental supervision.

Professionals expect non-electric air control about 192.2 billion market space, ultra-low emission thermal power market reform space of about 65.7 billion yuan, the whole vast air pollution control requirements.

In addition, the high diesel vehicle emissions, is also one of the main source of haze pollution. Considering the number of ministries had jointly issued by the Ministry of Ecology and environment "diesel truck pollution control tough fight Action Plan" diesel vehicles, boats become the focus of the next step of action to win the Battle of the blue sky.

Select heating boilers what are the considerations for the heating system, we propose the functional principle of the boiler and a lot of doubt, this simple to explain: household independent heating system, the first essential is a stable heat source, that is, heating boilers for the family is a simple heating boilers, for it is a city or a region, we need a lot of heating boiler heating stations were running protection of the public. 1. The inner two energy saving boiler combustion process, combustion of a fuel itself, and the other is to produce the fuel gas flammable mixture in a sealed high-temperature gasification and combustion processes. Boiler reasonable structure, the fuel gasification process stability, integrity, and the use of anti gasification burner, arranged dedicated economizer. Up to 85% thermal efficiency of the boiler, energy-saving effect. 2. The water temperature and water flow constant water temperature, no, no, no change, is a measure of the boiler is the main quality standards. Old residential water heaters commonly large amount of water or less, high or low temperature. According to a company's HVAC engineer, boiler now only one instead of the old heat exchanger, gas and water flow ratio control is not an exact match. But today's new boiler using a secondary heat exchanger. By completely secondary heat exchanger, complete remission contradiction gas two-phase flow of water, the water temperature is fairly constant, the flow does not change. 3. easy to control a good control system is an effective guarantee the normal operation of the combustion safety, testing, maintenance, daily operation and failure analysis are all important. Therefore, the choice of high-performance boiler is particularly important, especially for the elderly and children in the home. By-room temperature control not only the freedom to set their own needs heating temperature, can also be pre-set temperature before returning home, so that they will be able to enjoy the warmth of a home. 4. Look for boiler service procurement business, buying boiler products, especially large tonnage, is perfect after-sales service is an extremely important factor. In fact, due to the imperfections of production and after-sales service network, many boiler brands in the market is difficult to guarantee. Business and professional services to improve network and service system, not only the performance of enterprises and planning, more attention is to look at business and professional ability, each link is a professional, to ensure efficient and smooth transition of the whole process.
