Heat recovery system of the boiler with CO₂capture system

摘要

A boiler system including an electric power generation system having a boiler, a steam turbine for generating electric power by steams which received heat at a boiler, a condenser provided at the downstream thereof for condensing the steams, and a heater for heating condensed water by steams extracted from the steam turbine and, further, a CO2 capture system of sorbing and capturing a CO2 gas in an exhausted gas exhausted from the boiler by using a solid CO2 sorbent, and a chimney of exhausting an exhaust gas in the CO2 capture system after recovery of CO2 or an exhaust gas exhausted from the boiler, in which the temperature of a fluid concerned with the boiler system is increased by using the exhaust gas exhausted from the CO2 capture system.

1. A boiler system comprising:
an electric power generation system including:
a boiler;a steam turbine which generates electric power by steam heated at the boiler;a condenser downstream thereof for condensing the steam; anda heater which heats condensed water by steam extracted from the steam turbine; and further a CO2 capture system which sorbs and captures a CO2 gas in an exhaust gas exhausted from the boiler by using a solid CO2 sorbent; and a chimney which exhausts exhaust gas after recovery of CO2 in the CO2 capture system or exhausted from the boiler, wherein the system has a device for increasing a temperature of fluid for the boiler system by using exhaust gas exhausted from the CO2 capture system, wherein the device for increasing the temperature of the fluid is a device in which the fluid contains the exhaust gas exhausted from the CO2 capture system, and wherein the fluid for the boiler system is either a gas flowing into the boiler or an exhaust gas flowing into the chimney.
