Abstract
A circulating fluidized bed boiler is described, comprising a furnace, a loopseal, and a loopseal heat exchanger arranged in the loopseal. The loopseal heat exchanger comprises walls limiting an interior of the loopseal heat exchanger, a first particle outlet for letting out particulate material from the loopseal heat exchanger, an inlet for receiving bed material, heat exchanger tubes arranged in the interior of the loopseal heat exchanger, and a first ash removal channel configured to let out ash from the loopseal heat exchanger. An ash cooler is configured to receive ash from the first ash removal channel. In the loopseal heat exchanger the first ash removal channel is arranged at a lower level than the first particle outlet.
