model of large power station boiler
Analysis of Zhengzhou industrial model of large power station boiler scaling analysis of the real situation of large-scale power plant boiler has a full range of water treatment equipment Zhengzhou industrial boiler scaling the real situation, strict rules, comprehensive and complete laboratory projects and means, generally does not occur Boiler scale phenomenon. Boiler fouling generally occurs in the small industrial boilers, it focuses on scaling the case of industrial boilers, industrial boiler fouling situation has the following characteristics: first, the case of large enterprise scale boiler good small and micro enterprises. More formal management of large enterprises, while the initial investment usually have to buy a full range of water treatment equipment, water treatment procedures are relatively robust and effective implementation, operation and maintenance is relatively routine in place, a high level of knowledge of personnel, personnel to follow procedures operating. Boilers generally not fouling, or some boiler scaling a smaller area of thickness or less, because in the past some units do not attach importance to water treatment, causing boiler fouling, and later after changing ideas, to take measures to strengthen the water treatment operation, the scale can well controlled. And general small and micro enterprises, the concept behind weak management, lack of knowledge, poor management, lax supervision and management of the operator, the operator or lack of knowledge can not strictly enforce the rules, poor sense of responsibility, boiler with drugs or salt supply is not in place, not timely, boiler fouling situation is more common, some scale thickness and area of more than TSGG5003-2008 "boiler chemical cleaning rules" requirement, must be carried out chemical cleaning, and even some of the bottom of the boiler vertical boiler shell filled scale, hand hole can not be opened. Second, some units use surface water such as lakes or reservoirs, due to the large surface water turbidity, hardness is small, in the water treatment measures are not quite perfect, small scale inside the boiler or only some debris, dirt, scale relatively good deal, this case has little effect on boiler operation. And some use of groundwater units, because the larger individual areas of underground water hardness, water treatment measures in place, the boiler heating surface heap knot hard scale, a great impact on the hard dirt boiler thermal conductivity. So different sources of water supply boiler, the boiler can also cause fouling situation is different.
Chinese wine culture has a long history, wine blend. In the process of making wine, almost all wine prices are inseparable from the brewing process steam, we can say the stability and quality of steam purity of the wine production plays a decisive role. Lefort Wine has been committed to producing high-quality wine products, December 2016 No. 1, Lefort wine and I signed a one 4 tons of steam condensing steam model of large power station boilers, the company continues to provide high-quality wine work steam.
Because such gas model of large power station boiler equipment belongs to gas energy, so the cost is relatively low, especially compared with coal-based boiler, in the cost have been reduced, has become among the many companies will attention to the point. Not only that, now the manufacturers, because in the production of technical improvements, so this device, you can have a system of automatic control, added safety protection devices, etc., so when during use, do not worry about the safety of one of the problem.
Selection pressure hot water model of large power station boiler conditions What? For a larger number of floors, height or higher related businesses and institutions, the choice of hot water boiler, out of consideration of the actual situation, select the Metropolitan pressure hot water boiler, the selection pressure hot water boiler What are the conditions? Here Xiaobian take you to do a simple understanding. (1) The fuel pressure type hot water boiler, the thermal efficiency of the boiler, and so must be rated working pressure is under a relatively high steady state. Oxynitride (2) of the boiler, as well as other substances emissions compliance with national and local emission standards. (3) for heating relatively large range, relatively far from the heating, and the relatively high temperature requirements of the conditions, the need to use pressure hot water boiler. (4) pressure hot water boiler in the selection, to note problems with water treatment equipment, to ensure compliance with water, boost operational safety boilers. (5) provided in the high-rise building or a multilayer furnace room, the hot water boiler power is not more than a single 7MW, rated outlet water temperature not higher than 95 ℃. At the same time we shall obtain the approval and consent of the local safety watchdog fire department. Of course, the conditions for selection pressure hot water boiler is far more than that, regardless of which one aspect, we need careful handling and operation, if the timeliness of reach, it is very likely to cause a boiler accident, resulting in unnecessary the human and financial losses.
