COAL AND SYNGAS FUELED POWER GENERATION SYSTEMS FEATURING ZERO ATMOSPHERIC EMISSIONS

摘要

A coal syngas or other syngas fired power plant is provided with no atmospheric emissions. Coal or other starter fuel is gasified within a gasifier which also receives oxygen and steam therein. The oxygen is provide d from an air separator. Syngas produced within the gasifier is combusted with in a gas generator along with oxygen from the air separator. Water is also introduced into the gas generator to control the temperature of combustion o f the syngas with the oxygen. Products of combustion including steam and carbo n dioxide are produced within the gas generator. The combustion products are expanded through a turbine for power output and then separated, such as with in a condenser. Water discharged from the condenser is at least partially recirculated back to the gasifier and the gas generator. Carbon dioxide from the separator is compressed for capture without release into the atmosphere.
