Title: The application of CFB boiler & the problems when course
ABSTRACT
Circulating Fluidized Bed boiler is one of the high-efficient, low-pollution & general using technology, it has developed since 1980s, because its’ unique superiority with adapting more kinds of coal & strong changing burthen ability & low pollutant egesting, so the CFB boiler developed very fast. The development of elements and the procedure to decoke for CFB boiler bring benefit for society and economy.
This article introduces the normal structure of CFB boiler; Meanwhile expound the CFB boiler’s technique trait such as low-temperature burn, solid materiel fluidized circulating accompany high thickness & high intensity & high flux. This article also explain the CFB boiler’s merit, for example, burning efficiency, to decoke efficiency, NOX eduction, adapting more kinds of coal; And introduce the CFB boiler’s burning elements; At the last, the article emphasize the problems while CFB boiler working, such as not expedite of supply coal, heat surface abrasion, not expedite of withdrawal coal with withdrawal equipment, difficult for outlet dreg, and study the reasons of these problems & the disserve of these problems, giving the solve method.
