As the green word that natural gas in China has been widely promoted and popularized. However, the high gas prices but also to many of the business units using gas-fired boiler is very worried, which means it takes much fuel costs every year, to support the normal operation of the boiler, the boiler is how to save operating costs One of the problems business focus. Note that in addition to the use of natural gas boilers use a method other than the thermal efficiency of the boiler if the boiler itself is also an important criterion for energy conservation, today, Henan fast boiler on these issues to talk about what are the technical aspects of energy-saving gas-fired boiler.
The causes of boiler scale boiler water as a medium for heat exchange apparatus A specialty. During operation the surface of furnace and boiler water contact form thick layer of scale, over the years, people have dirt kinds of boiler scale due to the scale have been fully studied, introduced a variety of anti-scaling technology, but still not been completely resolved, while the development of antifouling cleaning technology, as an adjunct to maintain heating surface and the heat transfer surface. So, boiler scale is how did this happen? There are three main reasons: First, the boiler feed water impurities into the boiler, through continuous evaporation and condensation, boiler feed water, concentration of salts continuously increases, the degree of saturation or supersaturation, will be in the boiler metallic surface the precipitated precipitate. Second, with the increase of the boiler water temperature, the solubility of certain salts and inversely proportional to temperature, these salts at elevated temperatures, the solubility is drastically lowered opening formed scale. Third, the interaction of different salts or thermal decomposition to produce a compound difficult to dissolve. Boiler feed water in a continuous process of continuous evaporation, the pure water into steam by the boiler feeding the salt water continuous furnace substance was concentrated, the content of rising. When the boiler feedwater salinity level of saturation or over-saturation, salt materials will precipitate from the water, form a solid precipitate. Adhering a larger portion of their thermal load heating surface to form a hard or soft scale, another portion of the furnace was suspended in water with the boiler water circulating flows. When the heat receiving face of the poor circulation, the flow rate is low, then the deposition of scale on the heating surface to form a secondary, or deposited on the drum should not have high flow rates, a lower collection tank, dirt is formed, with the periodic sewage discharge from the furnace. Thus, generation of scale, in addition to the ingredients and contents of impurities in the boiler water related, but also to a large extent depends on the operating state of the boiler. The larger the water evaporation intensity, the higher circulation rate, the easier it is to generate water circulation easily broken loose precipitate, evaporation of the boiler assembly can reduce the number of scale on a surface. In contrast, evaporation intensity, the lower the cycle rate, the more easy to form scale on the surface of the evaporation boiler.
Therefore, to ensure a reasonable selection of boilers, paper and industrial users in the selection of the gas boiler, to note: 1, the fuel of choice to meet the environmental requirements; 2, flue gas emissions to meet local environmental policies; 3, choose energy-saving effect of a good boiler to ensure profitability;
Our company processes in multiple new energy automobile production will need to heat, the boiler equipment we choose is really a headache, fast Boiler solve our urgent needs. The purchase of electric water boiler system is simple, easy to operate, easy to maintain, high thermal efficiency, saving a lot of operating costs for our company. --customer feedback
