“…While the High pressure water tank is connected with the high pressure evaporator after the economiser. Superheater at the end of the boiler used as a steam dryer and to further increase the steam temperature.It is important to keep the temperature of the HRSG within a limit otherwise it may cause deformation and material cracks [18]. This high pressure and high temperature steam drives the blades of the turbine and generates electricity.…”

With the integration of intermittent energy sources in the power system, the main focus of thermal power plant design is to optimize the conventional system by improving efficiency and flexibility of power generation in the start-up and base-load procedures. This paper focuses on the behavior of thermal power generation with respect to load variations, fuel variations, weather conditions and internal dynamics of the system to aid in energy planning and the optimization of power system. Dynamic modeling and subsequent simulation is to make improvements. Therefore, to model the system, this research study has used a dynamic modeling and a simulation framework (OpenModelica based on modelica language) which is an object-oriented and equation-based language. This framework allows a non-causal modeling and a flexible reuse of the models since data-flow direction is not predefined like other state of the art simulating tools i.e. MATLAB. The proposed model analyses the trend of electrical power generation of KOT ADDU thermal power plant to predict the future demand of electrical power. The achieved results show more than 90% accuracy of the proposed model in the transient operation such as start-up and base load procedure.

“…By definition, AFR is the fraction of air mass and the fuel mass. Different research like [4] and [5] among others, have been conducted considering the quantification of the air composition and the fuel composition. In [6], the author quantified these masses for complete combustion and also formulated the heating capacity based on the composition of the fuel.…”

The control of the air-fuel ratio (AFR) is critical for the efficiency of the combustion. This is for achieving the better performance of the plant and result in high output energy. Computation of the AFR is gone considering the composition of the fuel regardless of the inlet pressure, density ad temperature of both fuel and the air. This paper models AFR as a function of the inlet temperature, density, and pressure. Formulated models have been checked using recorded data from the Jabana2 Oil Power Plant. The results show that the AFR increases by 1.5 units as the pressures of the gas increase by 0.6 bars but when it reaches 2.9 bar, AFR starts to decrease, 0.9% of the increase of the density leads to the decrease of the AFR of 0.4 in average. 3.5 o C rise of inlet temperature lift the AFR by 0.2; however, it starts to decrease when the temperature reaches 78 o C.

The control of the air-fuel ratio (AFR) is critical for the efficiency of the combustion. This is for achieving the better performance of the plant and result in high output energy. Different parameters influence AFR. This paper models AFR as a function of the inlet temperature, density, and pressure. Formulated models have been checked using recorded data from the site. The results show that the AFR increases by 1.5 units as the pressures of the gas increase by 0.6 bars but when it reaches 2.9 bar, AFR starts to decrease, 0.9% of the increase of the density leads to the decrease of the AFR of 0.4 in average. 3.5 o C rise of inlet temperature lift the AFR by 0.2; however, it starts to decrease when the temperature reaches 78 o C.
