In clean coal technologies, improving energy conversion efficiency is one of the most important directions. Compared to traditional subcritical power plants, pressure-increased supercritical power plants improve the plant energy efficiency from 35% up to 45%. This work presents a study of the thermodynamic behaviour of the water cycle in coal-fired boilers in response to the changes in energy demands.

Simulation-based research using COMSOL Multiphysics® software will be focused on the forced convection of supercritical water inside a heated pipe. The heat transfer coefficient will be evaluated in response to sudden changes in water conditions such as pressure, heat flux or mass flux, and thermal efficiencies.

As a result, the best working conditions from a thermodynamic point of view will be identified.
