Abstract
A vessel system (10) comprises an outer shell (14) of carbon fibers held in a binder, a coolant circulation mechanism (16) and control mechanism (42) and an inner shell (46) comprised of a refractory material and is of light weight and capable of withstanding the extreme temperature and pressure environment of, for example, a coal gasification process. The control mechanism (42) can be computer controlled and can be used to monitor and modulate the coolant which is provided through the circulation mechanism (16) for cooling and protecting the carbon fiber and outer shell (14). The control mechanism (42) is also used to locate any isolated hot spots which may occur through the local disintegration of the inner refractory shell (46).
Claims17
A vessel system capable of withstanding high temperatures and pressures comprising a plurality of shells:
- one of said plurality of shells constituting a closed, pressure containing outer shell comprised of carbon fiber held in a resin binder;
- means for cooling said outer shell which includes at least one separate cooling element disposed inside of and separate from said outer shell for circulating coolant;
- and
- another of said plurality of shells constituting an inner shell disposed radially within and separate from said cooling means, said inner shell being of refractory material to withstand high temperature and being in free and open pressure communication with all of said outer shell.
A coal gasification vessel system comprising:
- a closed, pressure containing outer shell comprised of carbon fibers held in a resin binder;
- means separate from and substantially concentrically disposed inside of said outer shell and adjacent thereto for circulating a fluid to protect said outer shell from high temperature in the vessel system during coal gasification;
- and
- an innermost temperature insulating wall of refractory material concentrically disposed within and located adjacent said fluid circulating means, said inner shell being in open and free pressure communication with substantially all of said outer shell.
