Techno-economic Evaluation on Enhancing Cogeneration Plant ...

The boiler produces high pressure and temperature steam that expands in a backpressure steam turbine and produces electric power for the internal needs of the mill. The exhaust steam from the turbine goes to an accumulator (LP steam main) that distributes the steam to various processes in the mill.

Techno-economic analysis and optimization of the heat ...

The thermal energy of boilers exhaust accounts for approximately 38% of the total energy of fuel input. Given these factors we conducted a techno-economic analysis and optimization design of the heat recovery system using boiler exhaust gas. This research is conformed to the principles of thermodynamic heat transfer and hydrodynamics.

Nov 15 2019 · 1. Introduction. The temperature of boiler exhaust flue gas normally ranges from 120 to 150 °C in coal-fired power plant (CFPP). The heat loss of exhaust flue gas accounts for approximately 5080% of the total boiler heat loss and 38% of the total energy input of CFPP .This means that recovering waste heat from boiler exhaust flue gas could improve boiler efficiency and reduce emitted ...

Industrial Boiler Efficiency Calculation & Factors ...

Boiler efficiency measures the relationship between the energy input and energy output of a boiler system. This ratio is expressed as a percentage and is used to assess the performance of the boiler and the burner as a means to determine the fuel costs of your boiler equipment investment. In fact the ongoing fuel usage costs are the most significant portion of your investment even more than your initial capital expense so it is important to understand boiler efficiency
