multistage boiler feed water pump manufacturers

CAUSE industrial multistage boiler feed water pump manufacturers scale formation of what are the reasons for the industrial boiler scale formation which has industrial boiler scale formation which has first of all, water treatment measures are not in place. Situation local industrial boiler water treatment methods are set out below: Some of the salt tank with the use of small water treatment apparatus (hereinafter referred to as the outer pot water), some of trisodium phosphate and sodium hydroxide was added to the pot (hereinafter referred to as pot- ), while some units are not taking any water treatment measures, direct operation of the boiler. The outer pot using water, some units in the design of a water treatment system, the local water quality testing is not performed, the washing apparatus and the backwash time are not set according to local water conditions, the hardness of the water supply when a large, positive and negative wash time is inadequate. Are washed lack of time, can cause water supply quality standards, and the lack of time will result in the backwash exchange properties of the resin gradually decreased until failure. In the selection of water treatment equipment, water treatment equipment selection of some units capacity is too small, does not match the rated boiler evaporation, can not meet the water supply needs. Also in the installation and operation of water treatment equipment, water pressure does not reach, it will also affect the normal operation of water treatment equipment. The use of pot-use units, some only use sodium hydroxide or unreasonable use of the ratio of two drugs, an insufficient amount to some at the time of dosing pot, add the drug, or add less than the frequency of drugs, or frequency is not fixed, sometimes pay more, sometimes less plus, often when the operator aware of the dosing dosing, failure to strictly follow the rules dosing, the drug failed to change according to changes in boiler load of the added amount, this will non-compliance resulting in water supply, boiler heating surface fouling. A situation that prevails, and a great influence on boiler fouling. Second, the sewage is not a lack of diligence or emissions. Some people in charge of rural baths, sewage think too much waste, sewage is not timely or a small amount of sewage, resulting in high concentrations of calcium and magnesium ions and salts can not be discharged, calcium and magnesium ions inside the boiler and salt concentration gradually, gradually formed scale. Increase managers are not aware of boiler fouling caused by coal consumption, the loss of economic costs and the impact on safety. Others are lax management unit, boiler rules are not perfect, fireman inadequate business knowledge, sense of duty, these conditions can also cause sewage below standard. In addition, industrial boiler units are generally not full-time water quality laboratory technicians, laboratory technicians and no part of the water quality, clear quality of the boiler feed water and boiler water, can only be opened when found inside the boiler scale realized that quality is not up, or unable to make timely feedback regulation, resulting in increased internal boiler scale or the amount of scale which has to a certain extent.

Main steam temperature in the multistage boiler feed water pump manufacturers when a hot start is less than the rated Why? Hot Start For the boiler itself, in fact, is to a certain stage of the whole process of Cold Start as a starting point. When the unit stopped running, the boiler cooling faster than the turbine. If the turbine is in a semi-hot or warm, cold boiler may already start operation of such boilers essentially as cold to warm, boosting, to try to meet the red hot state turbine revolutions required parameters for input large amount of fuel, but this time only by the amount of the bypass system and a steam exhaust air is not enough, so that the steam temperature rises rapidly, and the walls and high temperature. Also, because the combustion chamber and the flue outlet larger width, uneven temperature distribution in the furnace, the superheater tubes are not circle the steam flow rate, the temperature difference is large, causing local over-temperature superheater tubes. To prevent over-temperature superheater, extending its life, so to start the predetermined process in the main steam temperature should be lower than the rated 50 ~ 60 ℃.

ZG supply large coal fired circulating fluidized bed multistage boiler feed water pump manufacturers mainly including 75 ton coal fired circulating fluidized bed boiler and 110 ton coal fired circulating fluidized bed boiler.

Since more than six months since the multistage boiler feed water pump manufacturers equipment, heating and hot water supply well, our technical staff also view real-time remote monitoring and control through the use of the boiler to the scene, Baiyun Quan Lake hotel management staff related to our technical staff gave very great encouragement and affirmation. --customer feedback
