FBC Boiler
FBC Boiler
Par Techno-Heat offers FBC Boiler with four-pass design ensures better heat utilization and ultimate thermal efficiency. The fluidized bed combustion furnace ensures very high combustion efficiency up to 95% even with fuel having very high ash, fine contents and having very low calorific value. The straight tube in generating bank enables manual cleaning & easy inspection. The headers are of welded type box headers with individual opening against each tube at both ends of generating bank.
Product & Technology News
- The larger tube diameter in generating bank, i.e. 76.2 mm OD, enables easy manual cleaning.
- The intermediate tube supports in the generating bank, which prevents tube sagging contributes to higher boiler life.
- The wide gap in tube spacing is 160 mm pitch, prevents inter tube space plugging by soot deposition permits trouble free operation without external cleaning as clogging of tube space with soot does not take place.
- Free-floating front header takes care of longitudinal thermal expansion. Hence, thermal stresses are not developed during heating. This design enhances boiler life too.
- Manhole is open at both sides of the drum for easier access to drum internals.
- The larger diameter drum coupled with drum internal steam separators ensures dry steam even at full main steam valve opening.
- Moderately larger furnace area and higher free board height, above grate, makes the boiler capable to burn low grade, high volatile & ash contained solid fuel efficiently without reducing rated steam generating capacity.
