This program is called HAD-WHRB which can design waste heat recovery boiler under waste gas condition. You can arrange various types of chamer type wall panel, superheater, screen, evaporator and economizer, and it is designed to be horizontal or vertical type. You are most likely to use one-drum type boiler design. The program can calculate the following contents.
HAD-WHRB01 ] Waste Heat Recovery Boiler
-
Flue gas conditions : Waste gas compositions with 2nd air flow
-
Included Gas chamber conditions
-
Evaporator : Pre-evaporator( Screen)/main evaporator with wall panel
-
Super heater type : Horizontal/Vertical type, 1st, 2nd and 3rd superheaters with wall panel
-
Economizer tube type : Bare tube type
-
Detail information of Thermal calculation
-
Detail information of heat transfer
-
Pressure drop : Gas side/Water side
-
Max. temperature of tube/fin metal tubes
