german boilers products

Measures: stop german boilers products operation, the safety valve closed valve. Purge or replace the check valve by urban quality inspection departments.

In recent years, the country frequent german boilers products explosion hurts. In order to boiler explosion hazard within the city limits of strangled in the cradle, Tongxiang City, Zhejiang Province Environmental Protection Bureau began efforts to expand the investigation and remediation action on the bathroom boiler.

To strictly implement the ban on burning district requirements, to further improve the quality of urban environment, improve ecological satisfaction, since mid-February this year, Tongxiang City, four environmental protection will be co-related units Indus streets, to carry out this major investigation large heating boilers campaigns, decided to launch a big investigation on urban use hot water bath, foot bath shops, hotels and other business, the use of high-polluting fuel combustion zone ban on large renovation of heating boilers, continuous efforts to fight the "battle of the sky" .

According to preliminary statistics, the use of hot water units to provide services related to nearly 100 within the city limits, as of now, the investigation related to environmental protection has four units of 65, found that the use of biomass boilers 6 sets, 1 small coal-fired boiler units, diesel 1 small boiler units.

According to the investigation objectives edge side of remediation, environmental protection and the use of four pairs of high-polluting fuel boilers Daihatsu small bathroom has been ordered to stop using it immediately; the use of biomass boilers units of gold Water Cube, has been ordered to make corrections, use clean energy heating or hot water outsourced way.

"After a major renovation a few years ago, the small coal-fired boilers have been basically eliminated banned, but there are still dynamic changes and new heating boilers. Next, we will continue to carry out large investigation heating boilers, within city limits investigation and implementation of full coverage, and we will also carry out rectification 'look back', initially planned to be completed this major investigation big campaigns before the end of April. "Zhu Yaming, director of environmental protection four said Tongxiang three cadres of the Conference" seven action "mobilization meeting sounded the full implementation of" urban quality improvement action "horn, as" beautiful Tongxiang "vanguard construction, environmental protection and ecological environment people will be" two upgrade two down "as the goal, create beautiful ecological upgrade urban quality, Tongxiang boost economic and social development of high quality, is to make people's lives better and make unremitting efforts.

Single large german boilers products load adjustment flexibility is poor, and most are coarse adjustment by artificially staged by "the size of the fire", "top fire" or the realization. From the outside weather conditions change frequently, the larger the magnitude of the initial heating, adjust the end of the performance, the traditional boiler boiler unit determines the actual output is difficult to match the actual load required, often resulting in less heat and overheating occurs, that is often said the "supply and demand" so unnecessary additional excessive heat loss while the deterioration of the quality of the heating. In accordance with relevant domestic literature of statistics, domestic fuel, overall load factor in gas heating boiler (includes backup device), the thermal efficiency is maintained at most 45%, 72.7%, and this is very uneconomical, but this has not been caused by two indicators Experts attention. According to the advanced standards in terms of energy above the boiler system comprehensive utilization rate is also very low.

2) it is difficult to guarantee the quality of steam

As the load of the oil-fired boiler decreases, the temperature and humidity of the steam will be affected, especially for the boiler with superheater, when the load of the boiler decreases, the outlet steam temperature will also decrease, which makes it difficult to maintain the rated steam temperature. The quality of steam is getting worse. When the superheated steam temperature drops below the rated value, the heating surface condition of the steam-water system will enter the dangerous area, and the load at this time is called the technical minimum allowable load.

3) the acid corrosion of the tail heating surface of the boiler, such as air preheater, economizer and hot water boiler body, is aggravated.
