摘要
The invention relates to a high temperature ash adhesion testing system for measuring ash adhesion force on the boiler tubes at different elevated temperatures in pulverized coal fired boilers, comprising: a shaped body demarcated by a fixed stage (5) located at bottom portion of the body, and a moving stage (1) at upper portion; a force sensing unit (3) connected to a load cell, the force sensing unit (3) measuring the force between said two stages (5,1); a coated specimen (7) to be tested placed on the moving stage (5) being covered by a punch and die set (8) which accommodates an ash pellet (9); heating elements controllable by a PID Controller (6) placed between said two stages (5,1); a cooling device (10,11) attached to said specimen (7) for particular period; a double acting hydraulic cylinder (4) for application of tensile load to separate the ash from the coated substrate (7), the load cell (2) sensing and measuring the adhension force.
