PROCESS DESIGN OF STEAM BOILERS (PROJECT …

Draft - Draft is the negative pressure (vacuum) of the flue gas measured at any point in the boiler, expressed in millimeters of water column (kilopascals). Economizer - A series of tubes located in the path of the flue gases. Feedwater is pumped through these tubes on its way to the boiler in order to absorb waste heat from the flue gas.
