Abstract
The US Department of Energy (DOE), in partnership with United Technologies Research Center (UTRC) and Foster Wheeler Development Corporation (FWDC), is focusing on its Combustion 2000 Program aimed at developing inherently low-polluting high-performance power system (HIPPS). The UTRC concept is the development of an inherently low CO2 emitting coal-fired power plant based on thermodynamic optimization of indirectly fired combined cycle configurations using a topping Brayton cycle and a bottoming Rankine cycle. The UTRC HIPPS technology embodiment allows a baseline efficiency of 47%, and efficiencies approaching 55% are realizable using advanced cycles. FWDC is developing an all coal-fired system utilizing a pyrolyzer to convert coal to fuel gas and char. The fuel gas is sent to a turbine combustor, and the char is burned in FWDC's version of the high temperature advanced furnace. This chapter also reviews noncryogenic oxygen production technology, which is based on a class of dense ceramic materials that conduct oxygen ion at high temperatures.
