Analyses the characteristics of the heating medium. Points out that high temperature water is widely used because of more advantages than steam. In view of the dissatisfied heating effect in coal handling structures of several plants, puts forward some suggestions such as enhancing the heat insulation of building envelope, setting static balance valves on return water pipes and constructing according to correlative guides, to which due attention should be paid in design, procurement, construction and operation management, etc.
