WebApr 18, 2024 · The TaoTronics TT-HE001 is a small and compact space heater. As a result of its small size, it is perfect for smaller spaces, such as bedrooms and offices, that are in need of some extra warmth. To make use of this space heater, you will need to choose from three different heating modes. These heating modes include a 900-Watt heating mode, a ... WebFigure 1 shows a standard high pressure feedwater heater; low pressure heaters are similar in design less the desuperheating zone. The three main zones of the feedwater heater are the desuperheating, the condensing and the drain cooler or sub-cooling. Boiler feedwater is pumped to the feedwater inlet while extraction steam flows into the steam ...

Web• What is TTD and DCA ? Terminal Temperature difference TTD = T sat – T fw out here, T sat = saturation temperature corresponding to the heater shell pressure. T fw out = temperature of feed water leaving the heater . Drain cooler approach DCA = T drains - T fw in Where: T drains = temperature of the drains leaving the heater.
