Abstract
This paper presents methodology and results of a research project on software optimization of combustion process efficiency in coal-fired power plant.The general goal of this project was to increase boiler efficiency by proper control of the combustion process using optimization software, integrated with Distributed Control System and in-furnace temperature profile measurement system. The research goal relays on new approach in combustion modelling based on in-furnace temperature distribution and utilization of this model in on-line boiler control. it is assumed that this approach allows for more precise control of the combustion process, what finally has a positive influence on boiler performance – the efficiency in specific.The solution has been designed, installed and tested on existing, utility plant – 225MW (650 t/h of nominal steam generation). Final analysis has shown positive results – the boiler efficiency increased over 0.25%.
