SAMPLING PROBE AND IT'S SUCTION METHOD FOR RAPID QUENCHING OF PULVERIZED COAL PARTICLE

摘要

A sampling probe for quickly cooling a pulverized coal particle and a method for sucking the same are provided to accurately grasp the combustion state at a sampling point by rapidly cooling the pulverized coal particle and the reaction gas. A sampling probe for quickly cooling a pulverized coal particle comprises: a cooling water supply pipe(3) providing and ejecting the cooling water; a cooling water discharge pipe(4); a suction path(2) surrounded with the cooling water supply pipe and the cooling water discharge pipe; a helium feeding pipe(5) installed at the circumference of the suction path; a sintering metal unit(6) arranged between a top and a lower gap boards(7a,7b); a through hole formed on the top gap board; and a plurality of outlets(10) arranged at the outer circumference(9) of the suction path of an exterior at a same angle.
