Technoeconomic Analysis about Oil-free Ignition Technology of 1 000 MW Double-reheat Coal-fired Power Plant
-
Abstract
The ignition technology is extremely important for lower operating cost and ignition reliability of coal-fired power plant. The article discussed ignition technology (oil-less ignition, plasma ignition, natural gas Ignition) about 1 000 MW double-reheat coal-fired power plant from technological aspect, and developed an economic evaluation based on the actual unit. The result shows that for 1 000 MW double-reheat power plant, oil-free ignition technology has lower operating cost. Because of no operation experience, the risks and countermeasures for 1 000 MW double-reheat unit to take oil-free ignition are processed furthermore to offer reference for execution. The integrated technoeconomic analysis method can also be applied for ignition technology selection about other capacity units with its broad applicability.
