The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase steam package boiler overheat steam to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
When the package boiler overheat steam to conduct regular sewage? why? 1, on a regular basis during boiler blowdown procedures Stokes provisions, when the pressure is increased to 0.3MPa, lower header to regular sewage water wall once. Its role is three: the first function is excluded in the second line box of precipitated impurities. The second effect is that the uniform temperature associated tank. Stokes waterwall process due to uneven heating, cycle rate waterwall tubes in each range, even some stagnant, which makes the entire second line different water tank, so that uneven thermal expansion of the header. Sewage regularly eliminates uneven heating, the circulation flow rate in the water wall tube is substantially equal to the same header. The third role is to check regularly outfall is smooth, if clogged sewage pipes, treated invalid, it is necessary shutdown process. 2, the initial ignition of boiler blowdown regularly at this time for regular sewage, discharge of water in the bottom part of the cycle, not only the impurities to be discharged, to ensure the pot of water quality, and the circulation loop heat exchanger to heat the weaker part of strengthened to prevent the local stagnant water cycle, so that each of the water system components uniformly expanded metal heating surface, reducing the temperature difference between upper and lower walls of the drum.
Users of the steam package boiler overheat steam is required, what does? When using any kind of device has its own various requirements, when the user uses steam boilers, and many also have their own requirements, so when users use this product, what are the requirements have it? First, we need to let at the time of use to achieve good thermal efficiency requirements. Because it is itself a type of heating equipment, if it is in use did not meet this requirement of 2, one is hard to make good use of user needs. Furthermore it is also not in the use of good energy efficiency.
The transformation of low nitrogen gas package boiler overheat steam common question is what low-nitrogen gas boiler in the transformation of what is a common problem? In order to solve the gas boilers fundamentally unacceptable emissions, low energy efficiency issues, many boiler to begin low-nitrogen transformation, and therefore inevitably encounter this or that problem in low nitrogen gas boiler reconstruction process. The following version will guide you through the four common problems Boilers nitrogen transformation. 1. What are gas boiler units need to be low-nitrogen transformation? The situation analysis, NOx emissions from boilers exceeds 80mg / m, NOx emissions from new boiler exceeds 30mg / m, the need for low nitrogen gas boiler transformation. 2. If the boiler does not fail to transform how to do? According to relevant laws and regulations clearly defined, since April 1, 2017, for boiler emission concentrations exceed 80mg / m + unit, punishable by a fine of 100 thousand to 1 million yuan less, the circumstances are serious, should be ordered to shut down. 3. transformation of low nitrogen gas boiler what good results are as follows:? (1) help to improve the thermal efficiency of the boiler operation, reduce operating costs to a certain extent. (2) more conducive to achieve the environmental effects, the boiler long run more smoothly, reducing the portion of the waste disposal costs. How about the safety performance of low-nitrogen transformation 4. The gas boiler? Low nitrogen transformation process in boilers, burners can be replaced, installation and commissioning, it is necessary to conduct the test run, likely to cause boiler accident. However, if you strictly follow this procedure there is no problem, this is a reminder to customers that quality burner in the selection process should be dominant, and should not be judged solely based on price. In short, there may be many problems boiler transformation process, we need to control the transformation from the macro to do thorough.

Aug 26, 2011 · Another way to look at the efficiency of both boiler types is this: The HRSG generates an additional 75,000 lb/hr of steam with a fuel input of only 75.6 million Btu/hr (subtract the fuel input at 100,000 lb/hr steam from the unfired case steam generation). The package boiler, on the other hand, requires 84 million MM Btu/hr (111.6-27.56).Learn More

Soluble-salt deposits may form at a superheater tube inlet as a result of excessive entrainment of boiler water solids with the steam. This can result in restricted flow. However, overheating and direct oxidation failures may occur in areas distinctly removed from the blockage, such as the bottom loops or the hottest areas of the superheater tubes.Learn More
