Percussive sounds ("banging," "hammering," or "knocking") and vibrations in boiler drums or pipes are serious operational anomalies that demand immediate attention. At ZOZEN, we engineer our coal-fired boilers (like the SZL water-tube and DZL fire-tube series) to minimize these risks, but they can still arise due to operational or system issues. Here are the primary causes and ZOZEN's approach to mitigation:
Common Causes & ZOZEN Solutions:Water Hammer (Steam Condensation Shock):
Cause: Ra...
Question details (Performance):1. High temperature of motor, fast temperature rise.2. Overload, high outlet pressure and frequent safety valve open often.3. The vibration is intensified, the side vibration of the fan motor coupling is large, and the fan body never vibrates to vibration.4. No obvious vibration was found in no-load test of fan motor. Answer: Fault reason:Fan bearing vibration is common fault in the operation, the vibration of the fan will cause damage of bearing and blade, bolt looseness, chassis and wind damage, fan vibration rises abruptly in the operation. this is because when the gas enter impeller and the rotating blade working face has certain angle, according to the principle of fluid mechanics, gas from non-working face must be a spiral blade, so the dust particles in the gas will slowly sedimentation due to vortex. Airfoil blades are very easy to accumulate dust. When the accumulated ash reaches a certain weight, a part of the large amount of accumulated ash wi
Specific performance:Low level alarm of expansion tank.Answer：Cause of failure:The pipeline system (including heater) has not been replenished in time after oil leakage or degassing. Troubleshooting:Eliminate system defects and add oil.
Water tube boilers are a popular choice in industries due to their high efficiency and ability to handle high-pressure steam demands. However, understanding water tube boiler advantages and disadvantages is essential when selecting the right boiler for your operations. ZOZEN’s SZS series water tube boiler stands out as an exceptional solution, designed to maximize the advantages while minimizing the disadvantages of traditional water tube boiler systems. Let’s explore how this state-...
When evaluating boiler systems, a common question arises: which of the following is a water tube boiler? Unlike fire tube boilers, where hot gases pass through tubes surrounded by water, water tube boilers reverse this design, circulating water through tubes heated externally by combustion gases. This configuration enhances safety, efficiency, and scalability, making water tube boilers ideal for high-pressure industrial applications. Among these, ZOZEN’s SZS series stands out as ...
