Plant Performance Improvements by Enhanced Combustion through Laser-based Optimization
نویسندگان
چکیده
The power generation companies have to seek more superior and sophisticated technologies in order to gain an edge on their competitors owing to continually rising demands by environmental and governmental authorities and consumers. Intelligent Combustion Optimization is a proven methodology to accomplish plant performance improvements, boiler efficiency increase and reduction in emissions. The Siemens SPPA-P3000 Combustion Optimization solutions allow plant operators to achieve these objectives. The purpose of the paper is to describe in detail the performance improvements achieved by using Siemens SPPA-P3000 Combustion Optimizer at Unit 4 of Huaneng Rizhao Power Plant, P. R. China. This unit is a 660 MW tangentially-fired, supercritical boiler. To balance the combustion better, a closed-loop optimization is delivered by manipulating fuel and air levels with the help of laser measurements which provide the key combustion components O2, CO, H2O and temperature simultaneously, directly in the furnace.

متن کاملFuzzy optimization control for NOx emissions from power plant boilers based on nonlinear optimization
Combustion optimization adjustment can effectively suppress NOx emissions from power plant boilers. Current combustion optimization adjustment methods involve nonlinear optimization based on the boiler combustion model, such as optimization by a genetic algorithm or particle swarm algorithm. The computational complexity of these methods results in poor real-time performance, which limits their ...

In this paper, a multi-objective enhanced imperialist competitive algorithm (MOEICA) is presented. The main structures of the original ICA are employed while some novel approaches are also developed. Other than the non-dominated sorting and crowding distance methods which are used as the main tools for comparing and ranking solutions, an auxiliary comparison approach called fuzzy possession is ...
متن کاملCombustion Optimization in a Hydrogen - Enhanced Lean Burn
Lean operation of spark ignition (SI) automotive engines offers attractive performance incentives. Lowered combustion temperatures inhibit NO, pollutant formation while reduced manifold throttling minimizes pumping losses, leading to higher efficiency. These benefits are offset by the reduced combustion speed of lean mixtures, which can lead to high cycle-to-cycle variation and unacceptable eng...
