Introduction Gasifying biomass to produce a combustible gas provides the possibility for much more efficient overall conversion of a given biomass resource into electric power than is possible with traditional combustion-based technologies. In particular, gasified biomass can be used to power internal combustion engines (ICEs), gas turbines, and fuel cells, all of which are able to produce elec...

The aims to reduce harmful emissions are influencing increasingly the modern-day production of energy, while higher objectives are set also for the efficiency of combustion processes. Therefore it is necessary to develop such data analysis and modeling methods that can respond to these demands. This paper presents an overview of how the formation of nitrogen oxides (NOx) in a circulating fluidi...

This paper deals with the application of state space neural network models to fault detection and accommodation of the boiler unit. The work describes two aspects. First one is the fault detection and in this paper to diagnose the fault the three methods are described and compared: simple and adaptive threshold and more robust method which is model error modelling. The second part of the paper ...

This paper presents a model predictive control (MPC) strategy based on genetic algorithm to solve the boiler–turbine control problem. First, a Takagi–Sugeno (TS) fuzzy model based on gap values is established to approximate the behavior of the boiler–turbine system, then a specially designed genetic algorithm (GA) is employed to solve the resulting constrained MPC problem. A terminal cost is ad...

A simple simulation using SIMULINK is presented to model the thermal/control behaviour of a domestic gas boiler. The simulation was the first step in a research programme to investigate the efficacy of control using an oxygen sensor. A brief review of boiler control is used to outline current practice and research developments. Ratio control in several forms has been investigated. Performance i...

Relational transducers mapping sequences of input relations to sequences of output relations are proposed for high-level declarative specifications of business models. See [404] for a related class of ASM-transducers. Contains the problem description for the steam boiler control competition [7] and 22 proposed solutions obtained using the major known formal methods, with text and complete docum...
