Reheaters - an overview | ScienceDirect Topics

The outlet pressure of the superheater in a subcritical drum boiler, for example, is for example at 18.6 MPa, while the outlet pressure of the reheater is only 4.0 MPa. When a supercritical boiler is operated under normal load, the heating surfaces of the reheater and superheater have to increase in order to meet the heat requirement for

Construction and Working Principle of Lancashire Boiler

May 12, 2018 · When the boiler is operational, then the flue gases pass through the fire tubes and side and bottom space. The great thing for this boiler is that water level inside the drum is always above the side channels of flue gases. For this reason, more heat can transfer to the water. But the water drum is not completely filled with water.

The Difference Between Vertical Boiler And Horizontal

Another reason is the customer misunderstanding, sideways is the horizontal boiler, standing is vertical boiler, such as many customers think that the bulk of fluidized bed boiler is large vertical, but for this kind of boiler, and no vertical or horizontal points. The characteristic of vertical boiler is that the combustion part adopts a double grate combustor, and the heating and boosting are fast.
