Principle of operation: Generated steam is transferred into the turbine that rotates the electric generator where electric energy is produced. Steam is then directed into the condenser, where it is condensed and releases thermal energy to the heating water. After condensation, the steam is returned to the boiler, and the cycle is repeated. Additional thermal energy is produced in the flue gas condensing economizer and is also transferred to the heating water.
Standard biofuel-fired power plants operate according to the cogeneration principle, which is a process of simultaneous production of heat and electricity. Thermal energy produced by the combined heat and power station is used for the water evaporation process. Additional thermal energy is produced in the flue gas condensing economizer and is also transferred to the heating water.
