Jul 24 2017 · The Ash Fusion Temperature AFT test became popular in the 1920’s as a way to judge clinkering on the grate of a stoker fired boiler It was not designed to work on pulverized coal PC units
Ash fusion temperatures are determined by viewing a moulded specimen of the coal ash through an observation window in a hightemperature furnace The ash in the form of a cone pyramid or cube is heated steadily past 1000 °C to as high a temperature as possible preferably 1600 °C 2910 °F The following temperatures are recorded Deformation temperature This is reached when the corners of
The ash fusion temperatures AFTs of coal mineral matter at high temperature are important parameters for all gasifiers Experiments have been conducted in which mixtures of selected coal ashes and SiO2 Al2O3 CaO Fe2O3 and MgO were subjected to the standard test for ash fusibility The computer software package FactSage has been used to calculate the liquidus temperatures of coal ash
Sep 19 2018 · There exists a number of studies demonstrating that the chemical and mineral composition of the coal ash governs its melting characteristics and fusion temperatures Gray 1987 Kucukbayrak et al 1993 Vorres 1979 Vassilev et al 1995 Winegartner and Rhodes 1975Since the composition of the ash influences the AFT magnitudes and thereby performance of a coalbased
Fusion temperatures are measured over short time periods while heating ash at a rate of 8 3 ºC 15 5 ºF per minute whereas ash deposits typically accumulate for hours and are formed during cooling relative to the bulk gas temperature Fusion temperatures do not account for either boiler design or boiler operation both of which strongly influence slagging and fouling behavior
Pure silica typical highsilicon coals Xuanwei area China and their low temperature ashes LTA were selected to carry out a vaporization experime
51 The design of most coal combustion and coal conversion equipment anticipates that the ash either remain solid or assume some degree of fluidity depending on the particular design Ash fusibility temperatures help predict whether the ash will perform properly in the process for which the coal
