  • The CFB boiler produces less NO x emissions than PC boilers as the combustion temperature is lower. The air-distributor grate of CFBC is less critical than that of BFBC, since erosion of bed internals and heat exchanger tubes is a major concern for BFBC. In CFBC, air-distributor grates are narrow, deep, and operate at much higher velocity

  • W ith the heating season starting, it is only appropriate to discuss boiler inspections. The only way to truly know the overall performance of a chemical- and/or equipment-based program is to conduct an internal inspection. Simply sticking one s head in the manhole will not cut it. Typically, boilers are opened for routine maintenance and

  • Improper steam quality can lead to tube failures in the boiler, as well as turbine blade damage, resulting in large availability loss. The cleaning of internal surface of high pressure boiler can be grouped into two main methods, one pre-commissioning and the other post-commissioning cleaning. Pre-commissioning cleaning

  • Follow the boiler manufacture’s cool down procedure and be sure to rinse out the boiler as soon as the boiler is cool to avoid dried and baked on sludge deposits later on. If the cooled boiler is to be left filled with water for an extended period of time, take the proper wet lay-up precautions to protect the boiler from corrosion.

  • Lurgi CFB boilers used an external heat exchanger (FBHE), whereas Foster Wheeler CFB (before 1994) did not. The differences between these two systems can be seen in Fig. 16.3. Lurgi CFB boilers use a CFB loop with an external heat exchanger (FBHE) where about 20–60% of the total heat (excluding the boiler back pass) is absorbed.
