Abstract

See full text

A combined heat exchanger including a flue gas cooler heat-transfer unit supplied with cooling fluid by a supply pump and an upstream GGH heat-transfer unit for circulation of circulating fluid with a downstream GGH by a circulation pump is arranged at an outlet of a gas air heater for heat exchange of flue gas from a boiler body for oxyfuel combustion with recirculation flue gases. A low-low temperature ESP is arranged at an outlet of the combined heat exchanger. A heat-exchange-duty adjustment device is arranged to regulate heats exchanged in the heat-transfer units in the heat exchanger such that at least flue gas temperature at the inlet of the low-low temperature ESP is kept to an inlet set temperature.
