Cyclone Boiler - an overview | ScienceDirect Topics

Instead of using high-pressure steam from the main boiler, the low-pressure steam generated in the biomass boiler is used to meet the process demands of the coal-fired power plant. Parallel co-firing offers more opportunity for higher percentages of biomass fuels to be used in the boiler.

Steam Cycle - an overview | ScienceDirect Topics

2.3 Boiler and steam cycle model. In the steam cycle shown in Figure 1, the pressure of the feed water increases to 2 atm by Pump 1. The feed water entering the deaerator is further preheated to 127 °C by the steam at 159 °C and 6 atm coming from the turbine extraction valve. The pressure of the preheated feed water rises to 67 atm by Pump 2.
