tips forbustion analysis ofmercial boilers

The purpose of the industrial tips forbustion analysis ofmercial boilers water treatment What are the specific purpose of industrial boiler water treatment has a specific purpose which boiler water treatment industry specific industrial boiler water which generally comes from groundwater or directly use tap water. Even if they look clean, but in fact contains a lot of impurities, boiler work easily lead to a lot of scale generated, affecting the thermal conductivity of the boiler, at the same time have a corrosive effect on metal structures of the boiler, boiler operation hazards. The main purpose of the timely processing of industrial boiler water is to reduce the harm of harmful impurities in the water or scale. The water quality has a direct impact on the work of the boiler. Fouling will result in thermally conductive boiler difference, steel contrast boilers, thermal conductivities only 1%, will seriously affect the thermal conductivity of the boiler, therefore, to raise the temperature of the boiler inner walls to protect evaporation, addition, it should increase blast volume boiler and the amount of coal feed, to enhance the exhaust heat consuming process, which can not be fully carbon coal combustion, combustion in the boiler will not significantly reduce the thermal efficiency. If the poor quality of the water will cause boiler corrosion, mainly in the following three aspects reflect: corrosion under the scale, oxygen corrosion and caustic embrittlement. Corrosion is mainly occurs in the inner walls of the boiler scale, iron ions contained in the water becomes high iron scale formation, leading to corrosion of the metal iron is accelerated under the scale, resulting in a new generation of scale, corrosion of iron finalized. In this regard, China has the exact requirements of the iron content in the water contained. Will result in poor quality or boiler fouling occurs Priming problems, and the main reason for the problem lies in the boiler water contains a lot of calcium and magnesium ions dissolved solids and other organic matter and fats, calcium and magnesium ions causing boiler fouling Effect heat transfer efficiency, while priming seriously contaminated steam. In addition, the water level gauge prone to bubbles, causing the water level does not display, automatic water level control system failure, resulting in a threat to the security of the entire boiler work. Therefore, handle the boiler water is very important, which affects the safety performance of boiler work.

On the "low nitrogen" process, the use of international tip side quickly premix, the FGE other combustion flue gas recirculation techniques, starting from the different positions of the tips forbustion analysis ofmercial boilers, the nitrogen oxide emissions fall again, less than has been achieved 18 mg / cubic meter remarkable results.

Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired tips forbustion analysis ofmercial boilerss within the city out of small coal-fired boilers remediation process. Up to now, the work has achieved initial success.

15 in the city with 20 kilowatts and above the coal-fired generating units, 13 units have ultra-low emissions; city table 292 with 20 t steam / hour or more coal-fired boilers, emission standards have reached the count 253 male , accounting for 86.64% of the proportion of the boiler with; the city built area of ​​10 steam tons / hour small coal-fired boilers 2962 units, out of a total of 29553 units, up 99.7% out of proportion, the basic completion of the national requirements out of the task.

In order to further improve air quality, improve people's living environment standards index, Changchun City by expanding the ban on burning area, improve the standard phase-out of coal-fired boilers, plans to use two years of urban 20 tons of steam / h coal-fired boiler (kiln) furnace eliminated.

By the end of 2017, the city has eliminated 20 tons of steam / hour coal-fired boilers 964 units; at the same time to speed up the central heating and (expanding) network as well as the pace of clean energy promotion, provide for the transformation of the city's coal-fired boiler control a strong guarantee.

In recent years, Changchun City, adhere to the full implementation of coal-fired boilers governance, to improve ambient air quality in Changchun City has played a positive role. 2017, good days Changchun 276 days, compared with 2013, an increase of 35 days; heavy pollution days 10 days compared to 2013, reduced by 33 days; major air pollutants respirable particulate matter (PM10) and fine particles (of PM2.5) were 78 mg / m and 46 micrograms / cubic meter, respectively, 39.5% and 37.0% decrease over 2013.

At present, in order to save more expenses, many enterprises often adopt unscientific methods to treat tips forbustion analysis ofmercial boilers water, and all kinds of tools and instruments used in the process of boiler water treatment do not meet the relevant regulations. For example, "three no" electronic anti-scale instruments and anti-scale agents and so on.
