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 specification of boiler feed water 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).
The paper industry is one of the industries with high energy consumption, high material consumption and serious environmental pollution. The energy equipment used in paper mills is usually a steam boiler. Contaminants generated by boilers can also cause many hazards.
Tell your specification of boiler feed water business, operating points premix condensing boiler premix condensing boiler is the new show condensing boiler, using a condensing boiler premix combustion technology, not only exhaust gas temperature is low, reduce harmful substance emissions; also allows fuel combustion, releasing more heat. Although premix condensing boilers currently on the market most of the use of intelligent control system is very simple in operation, and has a good safety performance and so on, but during the operation, the following points still need to pay attention to three aspects. First, prior to use to prepare for long-term work is not running or new premix condensing boilers, to make adequate preparations before starting work. First of all to clean up the boiler, it is extremely important for preparations for condensing boilers, for the next operation will be of great help. And fast boiler remind you that should be done in the correct order when starting the boiler, not free to adjust the order of operations. Second, pay attention to the details in the process of running premix condensing boiler, the boiler should be kept inside pressure always is in a stable state, and to control the temperature, so as to make it a better working condition; Therefore, to achieve real-time monitoring, once any abnormality occurs, immediately discovered and certain adjustments. At the same time, often also in the pipeline to discharge gas, which can well prevent the occurrence of vaporization boiler, regular work of the sewage water is also very reasonable and important. Third, control the pressure inside the boiler if the boiler pressure suddenly found inside a high rise in the premix condensing boiler process, it is necessary to pay attention to, and immediately investigate the cause. Normally this is because the water temperature is too high to cause vaporization occurs, it should be appropriate to reduce the water temperature. There is probably because there is no deal with clean dirt caused by clogging occurs, and therefore should be timely to do cleanup work. If found premix condensing boiler pressure sudden drop in between, then it should be timely to add water to the boiler, which mainly may be due to lack of water caused. These are the main points premix condensing boiler operation fast boiler for your summary. In addition, you should also give regular boiler blowdown work, this can be good to avoid the accumulation of dirt on the inside and cause clogging phenomenon. And in the process of condensing boiler running, it must control the water and return water temperature difference, the temperature should be controlled at less than 30 degrees, otherwise there will be some security issues.
Note industrial specification of boiler feed water water quality testing of water quality testing what are the considerations which industrial boilers (1) pay attention to scaling problems boiler. When carrying out inspections of the boiler water quality, pay attention to the problem of scale boilers. Boiler heating surface scaling, will not only affect the thermal conductivity of the boiler, but also can disrupt the normal structure of the boiler, affecting the normal operation of the boiler. Fouling will too concentrated so that the temperature of the steel sheet, the steel sheet could afford once over, will produce accidents. Moreover, the scale problem is a common cause of boiler accident, we need to attach great importance to staff fouling problems, do water quality testing. (2) pay attention to water treatment and work-related training of personnel. First, we must strengthen the progress of the work of the boiler water treatment, understand the importance of water treatment. Second, we must strengthen the training of staff so that it can fully understand the water treatment process. To make it have the necessary knowledge of water treatment. In particular, to strengthen the natural water, the impurities in the water for effective treatment to improve water quality. To pay attention when handling method, common in two ways, first, filtration, and second precipitation. In personnel training, to ensure that staff can master the common water quality testing methods and treatment, to master the professional knowledge, and constantly improve the quality of personnel. First, to ensure accurate test results of water quality, so as to smoothly guide the follow-up by the correct data. Second, we must strengthen the technical quality of the staff increase, so do the theory with practice. Third, the development of sound, a sound regulatory framework, the rule-based quality inspection can reduce boiler performance problems caused by poor water quality. (3) prevent boiler corrosion problems. Boiler corrosion problems need attention, which need to focus on sensitive monitoring of the boiler, the weak link in the water quality testing, monitoring whether it is corrosive. If the monitoring to corrosive media, to fully, completely clear. Taking into account the protection of the cold parts of the corrosion-prone parts of timely protection, corrosion has been the site for processing, so that you can effectively avoid the boiler cause further corrosion. (4) strengthen the supervision of water treatment. To further strengthen the supervision of the water treatment process, so as to improve the performance of the boiler, saving operating costs, reduce the occurrence of accidents. First of all, to supervise water quality around the normal operation of the boiler, to avoid adverse water quality. Second, we must strictly examine the quality of treated water in accordance with the relevant requirements, the supervision carried out, to achieve the quality supervision and inspection of the entire process. Only strengthen supervision, the implementation of routine inspections in order to truly improve the effectiveness of water quality tests.
