Steam Boiler: Classification of Circulation Water Steam Boiler

Based on circulation of water in the steam boiler, circulation can be commonly classified as follow: 1. Natural or thermal circulation. Water from steam drum is distributed to water drum and lower drum through down comer. Water in down comer is unheated water.
