The types of coal are multiplex in domestic small and medium sized boilers, and with unstable ingredients, the method of maintaining the amount of wind and coal supply in a fixed proportion of the wind adjustment does not always ensure the best economical boiler combustion process, the key of optimizing combustion is to modify reasonable proportion of wind and coal online. In this paper, a kind...

Achieving accurate control of main steam temperature is a very difficult task in thermal power plants due to the large process lag (8 to 10 minutes) associated with the superheater system and there exists a deviation of ± 10 °C in closed loop control. A control oriented boiler model and an appropriate optimal control strategy are the essential tools for improving the accuracy of this control sy...

Quality regulation of the combustion process inside the furnace is the basis of high demands for increasing robustness, safety and efficiency of thermal power plants. The paper considers the possibility of spatial temperature distribution control inside the boiler, based on the correction of distribution of coal over the mills. Such control system ensures the maintenance of the flame focus away...

According to the characteristics of boiler combustion process, we use image processing technique to extract features that characterize the features of flame. On requirements of good real-time performance boiler burning diagnose system, we develop a set of PC add DSP real-time image acquisition and burning diagnosis system on the 200MW boilers. The results show that the system is simple, practic...

An adaptive predictive control methodology is applied for a fossil fuel boiler control. The control algorithm takes advantage of a neuro-fuzzy identifier system for prediction of the boiler response in a future time window. An optimizer algorithm based on evolutionary programming technique (EP) uses the identifier-predicted outputs and determines input sequence in a time window. The present opt...

The programming of agents that are capable of reasoning about their actions is a major application of logic programming in Artificial Intelligence. FLUX is a recent, constraint logic programming-based method for designing reasoning agents that can sense, act, and plan under incomplete information [3]. An agent program in this language consists of a background theory, which endows the agent with...

AbstructThis paper presents the development of a control oriented boiler model carried out on the basis of fundamental physical laws, previous efforts in boiler modeling, known physical constants, plant data, and heuristic adjustments. The resulting fairly accurate model is nonlinear, fourth order, and includes inverse response (shrink and swell effects), time delays, measurement noise models, ...

Sludge is one of the main pollutants from sewage treatment and contains a high content water organic matter. The co-combustion sludge coal can bring about energy conversion sludge. However, moisture in inorganic generated by have adverse effects on combustion environment. In this work, through experimentation, it was demonstrated that does not release obvious toxic elements or create an environ...

Buildings play an important role to meet Sustainable Development Goals, especially regarding the use of resources and greenhouse gas emissions. They are increasingly designed with energy-efficient solutions their operations, while related natural is still insufficiently considered. In this article, a methodology in Building Information Modeling proposed measure resource climate footprints build...
