boiler tsp dosing in power plant

How to deal with a hot water heating system, a hot water heating system dirt long run, the system will gather a lot of dirt and water stains, if not addressed, will affect the operating results and boiler tsp dosing in power plant heating effect. How to deal with these stains and scale? 1, the water is softened salt water against calcium and magnesium scale these major induced species, the effective use of long soft water treatment method, i.e. sodium ions to soften. This caused the water in the boiler will scale method to dispose of the material and not into the circulatory system is and should be in the affirmative. If the raw water is injected and the whole heating system are replenishment of demineralized water, then the residue under high hardness standard soften water, water will not fully described actuation handle clean dirt substances, also in the raw water and softened water replenishment systems are state will produce a certain amount of water residue. Thereby associate the water treatment device to the magnetic field in recent years, which is manufactured in accordance with the water after a certain strength of the magnetic field into the boiler, causing crystallization of salt water scale is changed such that the new scale not generated, prompting the old dirt shedding It becomes sludge. I would like to note that, even when used in combination, the residual hardness of the water because the system will generate a certain amount of water residue. 2, decontamination decontamination disposed in the boiler room and the indoor inlet duct system, so as to effectively separate the water residue. But practice shows that separation effect is limited. In particular inlet disposed in the boiler room decontamination, it can be said that almost no separation. Regardless of which design is a vertical or horizontal filter and is used in larger volume to achieve the purpose of precipitating impurities separated from the water. Can imagine, however, the speed of water flow in the pipe nearly 2 meters / second metal filter unbearable flow impact force, coupled with the effects of corrosion life of the filter is difficult to maintain more than one month. And the volume of decontamination of how limited it can produce precipitation. Cyclone decontamination emerged in recent years is also problematic, this method often used in the separation of the gas particles. Water is different, the proportion of slag sand and clay in the composition with water in a large difference is only large particles, fine particles can not be separated, so decontamination cyclone separation effect is limited. So I did not have a good practice of separating the role of decontamination do? Yes, a large volume of decontamination tanks can play a good role separation. 3, in the boiler blowdown steam boiler blowdown is very important, and the effect is very clear, whether periodic or continuous blowdown discharge can effectively expel excess boiler water salinity. But in hot water boiler blowdown effect is not very obvious. The difference is that: first steam boiler feed water per hour only 10T, while the hot water boiler with capacity for 240T. It can be seen in the water flow of the hot water boiler is particularly large, as compared with more than 20 times the capacity of a steam boiler. The most commonly used method is to discharge, the circulation pump outage for 2 hours and then precipitated impurities in the water to be seen until the water drain valve is opened. However, this method has limited effect discharge, and the drum is provided as outfall lower header tank can not be drained away precipitate. 4, for cleaning stains proved that treatment by chemical and mechanical methods of combining the most effective cleaning slag. Some people think that after you configure a valid demineralized water facilities in the heating system and no more effort to clean. This concept is not realistic, it should be said, that there must be softened water treatment, but also combined with the cleaning method is the most effective and thorough approach. (1) inside the boiler cleaning winter operation after opening the boiler we can see a lot of red fluffy black slag deposited on the bottom of the drum and the collection box, also seen in the sheet-like water residue adhered drum, a water-cooled wall, the inner wall of the smoke pipe and collection tank. The water wash residue can be chemically or mechanically. Conventional mechanical means is prepurge; a better cleaning effect, but the pot is limited space, especially for pyrotechnic impossible to use the boiler tubes. Methods of chemical cleaning with high pressure water boiling out mechanical grab combination is effective, to the extent that can meet heating surface qualities of the composition. (2) After cleaning the winter run outside the network and indoor facilities outside the network and indoor facilities in the slag should also be cleaned, clean room facilities often simple people start cleaning, extranet cleaning slag recycling can be used under the functioning of the pump system in the room to deal with the sewage entrance decontamination method.

How to using a boiler tsp dosing in power plant economizer with high efficiency?

What is a Industry boiler economizer?

The onset of winter, to ensure the safe operation of heating boiler tsp dosing in power plants, recently, Fengning, Hebei Province Market Authority to schools, hospitals, residential, hotels, enterprises and other crowded places as the focus, to carry out security checks special action winter heating boiler.

The boiler safety inspection to check whether the action is mainly for the use of registration certificate, whether or not the maintenance, overhaul and maintenance, boiler safety accessories are conducted periodic inspection; the use of units to establish whether the relevant rules and regulations and safety rules, file information is complete, run record is perfect; whether the unit is equipped with the required safety management, whether fireman and water treatment personnel certificates; whether developed special equipment safety measures and emergency rescue plan, with related emergency rescue equipment.

Through this inspection, supervision and special equipment unit firmly establish the safety production of "red line consciousness" to strengthen the routine inspection of the unit and boiler maintenance work in a timely manner to eliminate potential accidents.

Internal CFB Boiler design

Internal natural circulation CFB boiler was designed to fire a Chinese anthracite coal at the steam conditions. The anthracite coal has a relatively low volatile matter content (8.5 per cent by weight as received) and high ash content (35 per cent as received). The lower calorific value is 4 420 kcal/kg (18.5 MJ/Kg). Circulating fluidized bed (CFB) combustion technology has proven its ability to efficiently burn a wide range of fuels while being friendly to the environment. It has proven successful for the combustion of sulphur- and ash-rich coals, such as low bituminous coal or anthracite, as well as residues of coal mining operation.
