Tecnología de construcción de materiales refractarios para calderas de lecho fluidizado circulante.

1. The construction process of wear-resistant materials in the combustion chamber

As shown in Figure 1, Este es el proceso de construcción de moldes resistentes al desgaste en los tubos de pared refrigerados por agua en la parte inferior de la cámara de combustión de una caldera de lecho fluidizado circulante.. The wear-resistant materials are fixed by metal pins welded on the surface of the tubes. Since this area is the dense phase area in the lower part of the combustion chamber, the material concentration is very high, and the mixing and turbulent flow are very strong, so the wear is very serious. In order to prevent wear, a certain thickness of refractory and wear-resistant castables must be lined in the lower dense phase area.
