  • Firetube vs watertube boilers: a comparison 2019-09-18
    There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.
  • How does a fire tube boiler start up when cold? 2019-06-28
    The action of starting up a fire tube boiler for the first time is already a cold start. As a result, the mechanical load in this type of boiler is much greater, as the main characteristic of cold starts is the absence of boiling water and greater stress on the connection and anchorage elements of the boiler. To make this start a bit easier for the boiler, the boiler operator should reduce the burner load to a boiling point.
  • How to solve the phenomenon of superheater explosion in circulating fluidized bed boiler operation? 2018-07-12
    (Question Details) Specific Performance:The pipe of superheater bursts in circulating fluidized bed boiler operation.The bed pressure indicator fluctuates little. Answer:  causes of failure:(1) Design Factors.(2) Manufacturing process, installation and maintenance quality.(3) The temperature control device is unreasonable or does not work properly.(4) Effect of operating conditions on overheating and explosion of superheater. Troubleshooting:(1) Report the fact to operator on duty and require operating the boiler in low load.(2) When the overheat damage is serious,please report it to operator on duty and require stoping the boiler immediately to prevent blowout of the near pipes.(3) Adjust the steam temperature as much as possible within the normal range.(4) If the superheater tube is not damaged badly, it has little effect on the temperature level of the steam, and it can be allowed to run in a low load range for a short period of time.
