Fluidizedbed Incineration With Heat Recovery

The addition of heat-recovery equipment can increase the capacity of fluidized-bed incinerators by about 20%

(Henmi, Okazawa, and Sota 1986). The plant shown in Figure 10.10.4 has been in operation in Tokyo since 1984 (Henmi, Okazawa, and Sota 1986). Heat recovery involves inserting a heat exchanger into the stream of the hot gases, which generates a supply of hot thermal oil. The oil is then used as the energy source to heat the sludge cake dryers.

The hot oil passes through the hollow inside of the motor-driven screws, while the sludge cake is both moved and
