boiler rotary cup burner manufacturers
Please emergency shutdown following conditions: relative to the normal shutdown, emergency shutdown of the boiler rotary cup burner manufacturers, said boiler abnormalities that, if not stopped immediately, it may cause some economic losses. Therefore, in the following conditions are met that should attract immediate attention, emergency shutdown operation. (1) When the boiler water level gauge water level drops below the lowest water level, through the "waters" law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation.
Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired boiler rotary cup burner manufacturerss 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.
What are the characteristics of the electric normal pressure boiler rotary cup burner manufacturers
Nowadays, the advanced electric atmospheric pressure boiler is a kind of energy conversion equipment, the user inputs certain electric energy to the boiler and outputs the steam, high temperature water or organic heat carrier with certain heat energy after the equipment capacity conversion. But the high-quality electric atmospheric pressure boiler has the wide range of application, the high safety performance and the high thermal efficiency characteristic, then, what are the specific characteristics of the excellent electric atmospheric pressure boiler? The details are as follows:
1. At present, the advanced first-class electric atmospheric pressure boiler adopts open-type pot slips, which can maintain atmospheric pressure and prolong the service life of the steel furnace in the process of operation. In addition, the circulating pump of the electric normal pressure boiler is installed on the outlet side of the steel furnace, so that the pressure of the boiler can be reduced. Moreover, there is no internal pressure in the boiler of the equipment, and the heating system has pressure, so the boiler water level is kept in a certain range when it is running with water tank or tap water.
2, electric atmospheric pressure boilers with strong environmental applicability and high quality can be allowed to be installed in unsuitable locations of other boilers, so the environmental applicability of electric atmospheric pressure boilers is strong, and no need to consider the problem of pressure relief in boiler rooms. In addition, there is no explosion danger for the electric normal pressure boiler with better performance, so the safe and reliable performance of the electric atmospheric pressure boiler is higher.
3, it is understood that the manufacturing process is simple and it is recognized on the market that the obsolete pressurized steel furnace, after being repaired, inspected and tested, can be transformed into an atmospheric pressure hot water boiler, thus effectively prolonging the service life of the general boiler. The cost of heating system is reduced. In addition, the electric atmospheric pressure boiler can also be made of ordinary steel, which can save high quality steel to a great extent, simplify the manufacturing process, and effectively improve the utilization efficiency.
Where do energy-saving projects boiler rotary cup burner manufacturers? Corresponding to the requirements of environmental protection policy, many companies began to conduct energy-saving boiler, where it can do energy-saving projects boiler? Currently, Xiao Bian learned many areas of Henan have to do this piece of business, of course, there are certain other areas . Now, Xiao Bian Zhengzhou fast boiler energy-saving projects, with everyone to do a simple understanding. In general, energy-saving boiler, we must first take into account the actual situation of the original boiler, to see local adjustment or removal of transformation. In addition, in the process of transformation, the transformation to meet the standards, according to the relevant provisions of the transformation, not free to change private, random change. Of course, no matter which side of the index will need to secure energy-efficient, cost-effective as the reference standard. Therefore, energy-saving projects boiler wherever do, as long as the result of the transformation in line with the transformation of our demand, production has brought real economic, environmental and social benefits like.
