steam boiler Agent system pressure for a plant

The presence of scale, corrosion and other problems of industrial boiler water quality testing pH of treatment water quality detection problem of industrial boiler water testing approach the problem of treatment of industrial boiler water quality detection problem of industrial boiler 1, controls the boiler water. Therefore, in the process, we should focus on different issues, to take a different approach for processing, in order to achieve tangible results. When handling scale problems, a processing method used comprises the following: First, before referring to water to enhance the detection of the water, and analyzing the characteristics thereof, to achieve further based on knowledge of the water, effective control. Second, combined with the detection parameters, the development of industrial boiler optimization program running to do to solve the problem of scale from the source. In dealing with boiler corrosion problems, with particular emphasis on strengthening the dosing process. For example, in an empty pot, when dosing, which calculates a reference shall be subject to a total volume of boiler water. In the boiler, the pharmaceutical formulations should be combined with the results of water quality tests conducted increase or decrease. In short, strengthen the control of the pH of the boiler water is very necessary. In general, it should be controlled 10.0-12.0.2, material hardness control industrial boiler raw water during use, also by strengthening treatment raw water hardness was controlled to control them. Raw material for the effective control of water hardness, can take the following approach: first, to monitor water quality in the boiler water, boiler and of the inspection results, select the appropriate treatment processes. Second, using sodium ion exchange treatment process or the like, and subjected to regular monitoring in order to control the hardness of the material of the raw water. Third, the raw water softening treatment, in order to achieve the desired effect. Fourth, the quality of the boiler water and steam in combination, to reduce the alkalinity of the raw water. In short, it is very necessary for prevention from a variety of ways.

10 tph SZS condensing gas-fired boiler for cable industryJiangsu Zhongmei Cable mainly produces power cables, fire-retardant cables for coal mines, various flame-retardant and fire-resistant special wires and cables. Wires and cables project production process requires a lot of steam, in which the extruder heating, mixing rubber equipment preheating process in the drive 1 ~ 2 h need to use 0.3 ~ 0.4 MPa low pressure steam preheating, cable continuous cross-linking process requires a pressure of 2.5 MPa steam as a heating medium. In recent years, through years of sustained and stable development, the company’s scale and overall strength have been continuously improved. In 2016, Jiangsu Zhongmei Cable replaced coal-fired boilers with gas-fired boilers. ZOZEN and Jiangsu Zhongmei Cable are both in the beautiful coast of Taihu Lake. As we all know, ZOZEN boiler has advanced manufacturing technology and complete equipment, the service life of the boiler is very long. After the inspection at ZOZEN boiler, Jiangsu Zhongmei Cable ordered two sets of  6 tph SZS condensing gas-fired boilers, which can fully improve thermal efficiency.

Fast one side condensing boiler steam condensate integrally advanced technology, with high efficiency, appearance, durable, cost savings, reduced noise, low nitrogen environmental advantages; self-developed by use of flue gas condenser waste heat boiler greatly increased thermal efficiency, while reducing emissions of harmful substances, can save a lot of fuel, compared with ordinary boilers, the average annual fuel cost savings of several million. Fast and well-equipped boiler unique cloud service 3.0 system, through remote monitoring of boiler operation, all-round ensure the safe operation of boiler.

The reason for the high exhaust gas temperature following points 1, leakage is serious leakage refers to the furnace, flue, etc. due to poor quality welding or other causes leakage phenomenon is an important reason for the high temperature exhaust gas boiler. Mainly refers to the furnace roof seal leakage, see the crater, and the bottom seal Manhole leakage at the sink; chimney flue leakage refers to leakage when the ambient air in the negative pressure operating chamber wall and at the flue imprecise, especially in the furnace end leakage greatest impact. Leakage will make the exhaust volume increases, exhaust heat loss will also increase. 2, hot air factor is too large the air ratio has an important influence on the boiler thermal efficiency and combustion conditions. When the air ratio is too large, the amount of the boiler flue gas emissions will increase, so that the boiler flue gas heat loss increases, induced draft fan, blower power consumption will increase, resulting in reduction in thermal efficiency. Choose the right air ratio, it will reduce the energy losses, get a higher thermal efficiency of the boiler, and the safe operation of the boiler. When the load changes, can be adjusted into the furnace fuel and air quantity, the corresponding changes in the combustion conditions. 3, more fuel moisture content on water in fuel combustion is the main cause burning fire difficult, and reduce the temperature of the combustion zone, the fuel may not fully burn. When the fuel water every 5% increase, due to the thermal efficiency of the boiler heat losses will drop about 0.5%. 4, heating surface scaling, fouling, boiler slag when the heating surface due to poor water quality when the water content of the fuel or the like caused by excessive scaling or corrosive conditions, will produce heating surface scaling, fouling, slag and other undesirable phenomena, will effect of heating surface and heat transfer to the flue gas, the flue gas can not be cooled in a timely manner, resulting in exhaust gas temperature.
