Currently the demolition and integration of clean energy and the transformation is complete, out of the task have been put in place, we have been completed out of eight coal-fired boilers and boiler room of the grid work, removal of nine coal-fired boilers (grid yet dismantled three, to electricity yet dismantled three), and has been able to "break two three clear", the remaining boilers will be completed by the end eliminated.
The transformation of low nitrogen gas my boiler is leaking water 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.

PH measured by pH paper Timing acid value of (1/20 minutes), it was maintained at 1 or less, when the pH value is stabilized within half an hour, and purge the system without gas evolution, the pickling process ends; 5, after passing rinse water, circulating add "Yunqing passivation pre-film" passivation to improve the corrosion resistance of boilers. After concentration of the whole system is stopped mixed solution was warmed to about 60 degrees cycle, soak for 2-3 hours, the passivating liquid discharge system, the cleaning process is ended. Note: 1, this product can not be eaten; 2, process handling, operation, wear protective clothing. Packing: plastic bags: 1 kg / bag 25 kg / bag.
Steam flow rate calculation and the weight of the steam my boiler is leaking water specific types: steam boilers this kind of boiler, which is both common and commonly used species, and, still in the box boiler products. So, if you want to know the manufacturer, then, you must be familiar with this kind of boiler. Therefore, corresponding to this requirement, the following will be to learn and understand the steam boiler, this achieves the above object. 1. steam boiler, heat one ton of steam, is how much is? Equivalent to National Cheng Kung University card, how much it is? Steam boiler, one ton of heat from the steam, from a professional point of view, is in the range of 2.7-3 GJ. However, if you want to get an accurate value, then, but also know steam parameters, so as to carry out. National Cheng Kung University and its equivalent card would probably be about 60 million kilocalories. 2. Steam the weight and emissions of steam boilers, how to calculate? A steam boiler, the steam is calculated by weight, is very simple, as long as the displacement of a ton of water when sewage is subtracted, to obtain specific numerical values. The boiler continuous blowdown, is to calculate the emissions, generally speaking, is multiplied by the continuous blowdown flow time to get emissions boiler.
