Generally speaking a boiler with more passes provides more opportunities for to transfer heat to the water in a boiler and operate more efficiently however boiler efficiency is highly affected by tube design and not simply the number of passesGet a Quote
· The under investigation is a 1000 MW e ultra-supercritical tangentially coal-fired tower-type utility as shown in Fig 1The furnace width between the two side-walls depth between the front wall and the wall and height are 2316 m 2316 m and 1134 m respectivelyGet a Quote

Based on the observation made on the boiler unit and 1 and 2 it was found that the existing behaviour shows higher rear pass temperature at both the left and right hand sides (LHS and RHS) of the furnace However the was found to be extremely high on the RHS compared to the LHSGet a Quote
The at the outlet of reheater will have to be maintained within a narrow band Reheater variation will have an impact on the cycle efficiency of the plant designers adopt methods like divided second burner tilting water injection gas recirculation etc to control reheater steam outlet There are other methods like Gas recirculation Excess airGet a Quote
Findings from the investigation were used to determine the tubes condition metallurgically before the removal The results show that the relatively high temperature at the area pass area did not affect the metallurgical property of the tubes Keywords: Boiler tubesar pass area SlagGet a Quote
