A new kind of hot.sand c.oling equipment.wit. vert.c.l spout.d-fluidized bed is developed in t.is paper. It.is similar t. t.e t.adit.onal horizont.l vibrat.ng fluidized boiling c.oler in princ.ple but.different.from it.in st.uc.ure. t.e proc.ssing princ.ple of t.e c.oler is analyzed. t.e influenc. of main st.uc.ural and proc.ssing paramet.rs on t.e c.oling effec. and it. mec.anism are researc.ed. Ot.er c.arac.erist.c. of t.e c.oler are disc.ssed also.
