The problems in steam shanghai huazheng boiler manufacturing co ltd operation and the start-up of magnetic driven centrifugal pump will encounter many problems, among which the main problems are low temperature corrosion, slow exhaust speed, steam and water supply pipe damage and so on. The low temperature corrosion occurred on the low temperature heating surface of steam boiler has several main points: chemical corrosion and electrochemical corrosion. These two kinds of corrosion occur basically on the wall at lower temperature than the acid dew point. Ash deposition on the heated surface of evaporation can sometimes accelerate corrosion. The reasons for the slow exhaust rate are as follows: outlet filter core obstruction; too small cross-sectional area or long pipeline of piping; filter mesh blocking at the inlet end; reverse stop The valve won't open. Solutions to this type of problem: replace the outlet filter core, replace the larger cross-sectional line, or shorten the distance of the line; clean the filter and install an air filter at the inlet; check the spring of the reverse stop valve. In addition, steam boiler is easy to appear steam, water supply pipe damage phenomenon: when the pipe leak slightly, make noise, insulation layer wet or leakage steam, dripping water. When the pipe blasting, make a significant noise, and spray steam, water. The change of steam or feed water flow rate is abnormal, the blasting site decreases before the flow meter, and after the flow meter, the flow rate increases. A drop in steam pressure or feed water pressure. When feeding jellyfish tube blasting In 2000, the water level of the operating furnace dropped. The main causes of these phenomena are: steam pipe overtemperature operation, creep expansion beyond the standard or running time too long, metal strength reduced. Steam pipe heating pipe is not sufficient, resulting in serious water shock. The poor quality of water supply results in corrosion of pipe wall. The local scour of the water supply pipe causes the wall of the pipe to be scrubbed. Abnormal operation of the water supply system, excessive pressure fluctuations, water shock or vibration. Bad installation, manufacture, material and welding. The solution is: if the water supply pipeline leakage is slight, can maintain boiler feed water, and does not expand the fault quickly, can maintain short-term operation, put into the spare boiler as soon as possible, if the fault is added Drama, a direct threat to the safety of personal or equipment, should stop the furnace. If the water supply pipe blasting, we should try to detach the faulty pipe section from the system as soon as possible, and if it cannot be unlined and unable to maintain the drum water level, the furnace should also be shut down. If the steam pipe leakage is mild and does not enlarge the fault quickly, it can be maintained for a short period of time and put into the spare boiler as soon as possible. If the failure aggravates, it should be shut down if the failure directly threatens the safety of the person or equipment. If the boiler steam pipe blasting, unable to supply steam or direct threat to the safety of persons and equipment, should also stop the furnace. In the case of steam pipe blasting, an attempt should be made to unlist the faulty pipe segment from the system as soon as possible.

It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
How the thermal efficiency of the shanghai huazheng boiler manufacturing co ltd in order to improve the TSGG0003-2010 "industrial boilers energy efficiency testing and evaluation rules" calculated in the thermal efficiency point of view: the thermal efficiency of the boiler ηj = 100% - (q2 + q3 + q4 + q5 + q6) where: Q2 is the exhaust heat loss, q3 incomplete combustion gas heat losses, q4 solid incomplete combustion heat loss, q5 is heat loss, q6 ash material is heat loss. To save fuel, improve the thermal efficiency of the boiler, common measures are the following: 1, the use of flue gas heat recovery technology to reduce exhaust loss of the main factors influencing the heat loss is the exhaust gas temperature. The higher the exhaust gas temperature, the greater heat losses. Currently, when most of the new boiler factory is equipped with flue gas heat recovery unit, such as economizers, half or full condensation condensing flue gas heat recovery device, these measures can effectively reduce exhaust gas temperature and improve the thermal efficiency of the boiler. 2, reasonable control air-fuel ratio, to optimize combustion and reduce the loss of incomplete combustion when the heat losses and the excess air coefficient is too high, excess equivalent of inhaled cold air into the furnace, this part of the cold air does not participate in the combustion of the excess, but vain drained after being heated, heat losses increase; cold air into the furnace as to continue to increase beyond a certain limit, the furnace temperature will be lowered, incomplete combustion can also cause loss increases. When the excess air coefficient is too low, the fuel can not get enough oxygen for complete combustion, resulting in incomplete combustion loss increases. The long-term severe incomplete combustion, boiler heating surface will result in carbon impact heat transfer efficiency, continues to increase exhaust losses. Therefore, the reasonable control of the air-fuel ratio to minimize heat losses and incomplete combustion losses q2 q3, is another key point to enhance the thermal efficiency of the boiler. 3, strict control of boiler water, boiler scale control SCIENCES water will contain various impurities and calcium and magnesium scale substances, boiler fouling inevitably. Low thermal conductivity of the scale, so that once the heating surface fouling due to increased thermal resistance, boiler exhaust gas temperature rises, heat losses will increase. Test data indicate that the boiler heating surface junction 1mm scale, heat losses will increase from about 2% to 4%, the thicker the scale boiler heating surface, the greater the resistance, the thermal efficiency of the boiler will be lowered more. Boiler fouling not only reduces the thermal efficiency of the boiler, and the boiler Heating Surface temperature rise, causing heating surface damage, and even cause boiler explosion. Therefore, high-quality soft water treatment apparatus, in strict accordance with the process operating boiler feed water softening devices, the control of boiler feed water quality, can delay scale formation. Meanwhile, boiler scale control in real time to master the situation boiler scale, a scale clean-up, if necessary, is also very important. 4, strengthen the insulation, to prevent leaking, reduce heat loss due to the boiler, the temperature of soda heat pipe system is better than the boiler room air temperature is high, some of the heat will be dissipated to the ambient air by radiation and convection, heat radiating boiler loss. Accordingly, when the insulation layer and the heat pipe boiler systems found damaged or leaking, it should be repaired, to reduce heat loss.
