Title:
HIGH TEMPERATURE SOLID HEAT RECOVERY WASTE HEAT BOILER AND METHOD FOR RECOVERING WASTE HEAT
Document Type and Number:
WIPO Patent Application WO/2020/029047
Kind Code:
A1
Abstract:
A high temperature solid heat recovery waste heat boiler and a method for recovering waste heat. The boiler is vertically disposed and is cylindrical. An upper portion of the boiler is provided with a material inlet (1). A lower portion of the boiler is provided with a material outlet (2). Supplied water of 4.5 MPa or more of a boiler system enters an inlet of a high parameter economizer (9), is heated inside the high parameter economizer (9), and then is sent into a high parameter steam drum (10). High parameter saturated boiler water above 4.0 MPa is formed inside the high parameter steam drum (10). The high parameter saturated water enters a high parameter front evaporator (5) and high parameter evaporators (71/72) along a high parameter boiler drop pipe (15), and forms a vapor-water mixture. The vapor-water mixture flows back into the high parameter steam drum (10) via a high parameter boiler riser pipe (16), and undergoes vapor-water separation inside the high parameter steam drum (10), so as to form high parameter saturated vapor above 4.0 MPa. Then the high parameter saturated vapor enters a high parameter low temperature superheater (62) and a high parameter high temperature superheater (61), so as to form high parameter superheated steam having a degree of superheating at or above 200°C. The method directly converts heat of high temperature solid particles into high parameter superheated steam, thereby improving heat efficiency.
