industry boiler in mongolia
Pressurization of water industry boiler in mongolia heating system for heating hot water heating system with a constant pressure common mode: constant pressure expansion tank, Common constant pressure supply pump, pressure tank, and the gas constant pressure, constant pressure steam, frequency control constant pressure supply pump, stable constant pressure water and other hydrating the constant pressure. Hybrid heater of the hot water system should be used in the form of overflow constant pressure. (1) the constant pressure expansion tank: In the embodiment above the highest point of the heating system 2-3 meters, provided a constant-pressure tank to maintain a constant pressure point is referred to as the constant pressure expansion tank. The advantage is that the pressure is stable afraid of power; disadvantage is the limited height of the tank, and when the higher maximum building floors away from heat, or high temperature hot water, the expansion tank erection height not meet the requirements. (2) Normal pressure up water pumps: heating system with a water supply pump continuously maintain a constant pressure point pressure of water filling method called fixed constant pressure supply pump. The advantage of this method is that simple equipment, less investment, easy to operate. The disadvantage is afraid of power outages and a waste of electricity. (3) a gas pressure tank, and constant pressure: nitrogen partial pressure of the given gas at constant pressure and two constant pressure air, is characterized by using a low-pressure tank, and the joint operation of water supply pump, the heating system to maintain a constant pressure. Constant pressure nitrogen is constant pressure filling nitrogen tanks. The constant-pressure air is filling the air, the air dissolved in water to prevent corrosion of pipelines, installed normally constant pressure in the air bladder tanks, the air and water separator. Constant pressure gas heating system advantages are: safe and reliable operation, can better protect the system and the vaporized water hammer phenomenon; disadvantages are: complex equipment, larger, more expensive, used for high temperature water systems. (4) Constant pressure steam: Steam is constant pressure by the pressure of the boiler drum vapor space ensured. For more than two boilers, may be employed externally constant pressure expansion tank vapor system. Further, the use of water spray produced by the present heater and the steam heater may be movable considered a constant steam pressure. Constant pressure steam advantages are: the system is simple, low investment and operational economics. The disadvantages are: constant pressure to steam pressure depends on the level of boiler combustion conditions, pressure fluctuations, if mismanagement steam fleeing into the water Netease cause water hammer. (5) Frequency constant pressure supply pump: The basic principle is to change the power frequency according to the pressure change in the heating system, smooth stepless adjustment of the supply pump and regulating the speed and fill water, constant pressure point for system pressure constant. The advantage of this method are: energy saving, easy to adjust the control pressure. The disadvantages are: large investment, fear of power outages. (6) a constant pressure water: tap water pressure during the heating system meet the heating value of the constant pressure and the pressure is stabilized. The water can be directly connected to the heating system return pipe, pay constant pressure. The advantage of this approach is apparent see, simple, minimal investment and operating costs; disadvantages are: narrow scope of application, and the quality is not directly heating process causes the heating system fouling. (7) forms the overflow constant pressure: constant pressure valve has a constant pressure, constant pressure and high water tank overflow pipe pressurization inverted U-shaped and the like. In operation, the highest point of the system is filled with water and there is inevitably a certain margin pressure head, and generally about 4m. Since the system is large floors for, and much smaller than the resistance of the return path for the resistance, and therefore, the runtime, the ram is higher than the highest point of the head rest. Thus, the value of the static pressure may be set appropriately lower, preferably generally 1 ~ 4m. Minimize pressure constant pressure value, in order to take full advantage of the ability to work in the steam.
Hechi City Industrial Boiler what brand it is a good moment for domestic industrial industry boiler in mongolia manufacturer, The contrast evaporation, each with its own case highlights industrial boilers. Analysis of the main industrial boilers do not understand the problem is really a problem of standards covering what. To choose the exact terms of normal industrial boiler units of everyone, as some of the specifications you need to know: One, two industrial boilers efficiency indicators, industrial boilers the steam speed Third, industrial boilers rated evaporation four, the type of comprehensive industrial boilers Some said earlier norms, the purchase of common industrial boilers certainly fail, and most certainly concerns the failure, from where some of the specification, a set of industrial boilers may know there is a real quality problem, of course, for industrial boilers process, to find a most correct all units, high-cost industrial boilers before they are most very important.
Hot water industry boiler in mongolia in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
When the industry boiler in mongolia blowdown work to strengthen and overhaul the content whether fixed: Under what circumstances, boiler blowdown should be strengthened? Boiler overhaul, it has what? In addition, circulating pump, which is on a different boiler, if there are different installation location? Ask these questions, its main purpose is to be completely resolved, so that we can learn to understand clearly, in turn, can enhance the degree of familiarity and understanding of their boiler of this important product. 1. Under what circumstances should strengthen the work of boiler blowdown? The problem, it seems boiler in the box, it is not difficult to answer, so they give a specific answer, is: When the boiler water testing, SiO2 content is too high, or too high alkalinity found to strengthen its sewage works, and that measures must be taken, it can not be taken lightly. 2. boiler overhaul, what it has? Overhaul of the boiler, which in terms of content, there is a major overhaul of the heating surface, the furnace wall repair, and overhaul of auxiliary these three, however, not every overhaul, these three should be carried out. So, boiler overhaul, it is not a fixed item. In accordance with the requirements, when half of the heating surface is thinned, to overhaul the furnace wall is once every six overhaul. And auxiliary equipment, is to see the actual situation, to determine the need for overhaul work.
