Boiler water hardness value is not up to what harm? Boiler is a heat exchange device, which is released when fuels will play a combustion heat transferred to the water, resulting in the role of steam. If poor water quality, the formation of scale on the heating surface, the generation of scale can greatly affect the boiler thermal conductivity. Typically the thermal conductivity of the object, the greater the thermal conductivity with thermal conductivity expressed, indicating enhanced thermal ability. Scale thermal conductivity than the thermal conductivity of steel decimal tens to hundreds. Therefore, boiler fouling generates the following consequences: (1) a waste of fuel. After scaling the boiler, the heating surface heat transfer performance deterioration, in order to maintain the boiler ratings, plus fuel must be more investment, thus wasting fuel. (2) heating surface damage. The junction of boiler scale, the temperature difference between both sides of the heating surface increases, the metal Bi temperature rise, decrease in strength, pot under pressure, bulge occurs, causing serious accidents and even burst pipes and so on. (3) reduce the boiler output. Scaling the boiler, the generation of scale will reduce the flow of heat receiving section of the inner tube, the inner tube to increase the flow resistance of the water cycle, serious or even completely blocked. This destroys the normal circulation of the boiler, impede heat transfer inside the boiler, reducing the evaporation capacity of the boiler. Thus, the economizer boiler output will be reduced, water wall, convection tube member and the like are corrosion in the boiler drum due to poor water quality and cause corrosion. As a result, these recesses and the thin metal member, and even perforation. More serious corrosion of internal metal structure will be destroyed. Corroded metal strength is significantly reduced. So, seriously affecting the safe operation of the boiler, shorten the useful life of the boiler, resulting in economic losses. After the metallic corrosion products are carried to the pan of water boiler heating surface, easy to form scale and other impurities. Iron-containing scale high, likely to cause corrosion of metallic iron in contact with the scale. The iron corrosion products and easily re-form scale. This is a vicious circle, which leads to rapid deterioration of the boiler members. Priming pot when water contains high sodium chloride, sodium phosphate, organic matter with a base role, grease or water has the saponification, in the boiling pot of water evaporation, the liquid level will produce a foam, the bubble is separated many water droplets, these salt content of many drops of water are constantly being taken away by steam. Priming occurs, the harm follows: Steam serious contamination; superheater tubes and steam pipes salt accumulation, severe plugging; so filled with the bubble level indicator, causing confusion level; water hammer effect, easily damaged piping connections steam system; easy to cause corrosion of parts of the steam valve, return elbow. Increasing the amount of boiler maintenance boiler plate or pipe has a scale after the junction is very difficult to remove, in particular due to leakage caused by boiler scale, cracks, breakage, deformation, corrosion and other diseases. Not only damage the boiler, and spend a lot of manpower and material resources to repair, not only shorten the running time, also increased maintenance costs. Boiler accident caused by accidents caused due to the scale, accounting for over 20% of boiler accidents not only cause loss of equipment. Also threaten personal safety. According to US statistics reports, boiler water treatment, from the global to say what is "lucrative" thing, but water treatment capital and operating costs, accounting for a quarter of the cost savings. Boiler hazard protection (1) the choice of specification boiler water treatment methods and facilities. Boiler unit should be based on the number of parameters, the boiler water situation, choose rational and effective water treatment methods, supporting appropriate water treatment systems and equipment to ensure compliance with water quality standards for boilers accordingly. ① rated evaporation amount is smaller than 2t / h, and the rated steam pressure less than or equal steam boilers and soft drinks dual 1.0MPa boiler pot-treatment may be employed. But we must strengthen the supervision of scaling, corrosion and water boilers, earnestly dosing, sewage and cleaning work. ② The chemical treatment of the outer pot, the selected period of ion exchange water system, exchange capacity, the washing water consumption, or an acid salt consumption and consumption requirements should match boiler output. And to run the economy. ③ boiler water treatment method should be selected in units of actual use, take the form of an outer pot and the pot water treatment method combining the methods. Pot-treatment as a supplement to the outer pot water treatment method, the metal surface is conducive to the boiler forming a protective film, to reduce corrosion. And can eliminate residual hardness, or the boiler can be thin Paradise scale operation, the boiler further reduce power consumption. To ensure safe operation of the boiler. 2) Water treatment operations must go through examination certificates. Each boiler units should strictly implement the relevant water quality standards GB1576 "industrial boiler water quality", we must adhere to the raw water boiler feed water, boiler water, return water and steam quality of daily laboratory analysis. Every time laboratory analysis of the project, data and appropriate measures taken, shall fill in the table on water quality testing records. Substandard water quality timely treatment, to ensure the boiler feed water and boiler water reaches the relevant provisions of national water quality standards. (3) specification installation and commissioning of boiler water treatment equipment. ① pot outside a water treatment system, after completion of installation of equipment should be carried out by the unit with debug capability to debug, determine a reasonable operating parameters; take pot-boiler commissioning process should be conducted by the unit with debug capabilities, determine a reasonable increase drug method and quantity. After the commissioning of water, steam quality should meet the requirements of quality standards, technical commissioning report shall be deposited in the archives boiler unit boiler. ② boiler water treatment system installation and acceptance is part of an overall acceptance of boilers, water treatment equipment should eliminate substandard hastily put into operation, planted accidents. Unqualified acceptance of boiler water, boiler will not send registration certificate.

Steam boiler in the boiler room operation in energy-saving power equipment mainly refers to the steam boiler feed pumps, 7 ton hot water boiler for sale circulating pump, fill water pumps, blowers, water pumps make life on Cleaner coal equipment. Electricity ranks second in heating costs fee. How to achieve energy-saving boiler to run it? Measures to reduce the power consumption of the boiler apparatus as follows: 1, the steam boiler feed pump, circulation pump hot water boilers, boiler drum by a fan apparatus main power frequency to frequency modulation, frequency conversion device start after stopping, of greatly reduced mechanical shock and grid current, improve equipment Kai, safety stop. After the devices using frequency conversion technology, significantly saving boiler than the frequency of 30% energy saving device. Frequency intelligent control of high precision, the water feed pump pressure error can be controlled within 0.01MPa. 2, instead of the motor drive circulation pump hot water boiler industrial steam turbine. 3, strengthen the management of electrical equipment, prohibited device "big horse car", part of the equipment can be run on intermittent intermittent operation, energy-saving equipment, elimination of large energy-consuming equipment, lighting do people go out the lamp, lamp often destroy Wait. 4, the use of scientific management, improve the heating network operation and management. The measure of the level of heating network hydraulic imbalance degree level are: water balance, disorders of 1. Is greater than or less than 1, the heating temperature is not lower energy consumption increase. There are many units employed operated flow balancing valve, the control valve is adjusted manually, preferably for energy saving effect. 5, the boiler room equipment arrangement should be reasonable, and reduce the length of the elbow channel number, smoke duct in order to reduce resistance loss.
