The slag flow rate and heat flux through a combustor wall were measured in a 24 T/D pilot plant of a coal partial combustor, which is one kind of slagging cyclone combustor. Results of computer analysis on the slag behaviour and the heat transfer were compared with good agreement to the test results. The computer model predicted the following characteristics. (1) The slag flow rate showed rapid increase or sudden decrease when combustion conditions were changed. (2) The effects of various factors were evaluated, including the firing rate, combustor stoichiometry, ash content, flux additive, air preheat temperature, enriched oxygen concentration, refractory thickness, cooling-wall temperature and the reactivity of coals.
