Biomass boiler for paper mill
ZG Boiler have been commissioned by many paper mill in many countries to undertake extensive servicing activities on a high-pressure steam boiler. we have gas fired boiler, biomass fired boiler, coal fired boiler to paper mill.
Water wall boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.
Customer Service Manager to show the party fast self-developed cloud services 3.0 system, customer management, manufacturing orders, tracking shipments, commissioning monitoring, data analysis, development of online features such as warranty, the boiler has become a "butler." For the convenience of the user to monitor operation of the boiler, combine mobile phone user habits, to invest in developing mobile client APP, to achieve fault repair, maintenance reminders, data entry, work order tracking and other functions, allowing users real-time dynamic control of the boiler.
Selection of how gas hot water boiler? Gas hot water boiler as the name suggests refers to the fuel gas hot water boiler, gas hot water boiler big advantage is energy saving and pollution-free, compact, small footprint, high degree of automation, automatic operation. Gas and oil-fired boiler and hot water boiler electric boiler is compared to the most economical, most people choose as a gas hot water boiler horizontal 3000 kg industrial steam boiler, heating and bathing equipment.
