ABSTRACT:
A carbon foam evaporator is described which can be used in a wide variety of operating conditions. The evaporator utilizes a carbon foam with a bi-model pore distribution. The carbon foam is thermally stable up to temperatures of at least 300° C., is rigid, and has a compressive strength of at least 100 psi. The carbon foam is also resistant to chemical attacks.
