Compared to [1], this work is not focussed on design aspects of the steam generator but rather on the changing structure of auxiliary power demand of an integrated overall process caused by a reduced flue gas recirculation.
Several sets of simulations were carried out to evaluate the effect of slope, temperature, pressure and CO2 concentration, which is significantly reduced if flue gas (i.e., without capture) is mixed with the brine.
The result shows that co-combustion can be carried out in CFB plant designed for the base fuel without exceeding EU or German emission limits for sludge energy fractions of less than 25%, except for the chlorine emission that may have to be reduced by flue gas treatment.
This paper proposes a new system that utilizes the remaining heat in sulfur-reduced flue gas, where direct-contact heat transfer and absorption technologies are used to even further reduce the exhausted flue gas temperature.
A feasible method to reduce the harmful flue gases emissions and to increase the efficiency is to improve the control strategies of the existing thermoelectric power plants.
In many oxy-fuel systems the flue gas stream is recycled and premixed with the fuel and oxidizer to reduce flame temperatures.
In order to reduce CO2 capture costs flue gas, which consists mainly of N2 and CO2, injection has been proposed.
Based on these analyses thermo-chemical equilibrium calculations were performed using the FACT-Sage simulation software to identify the effect of reducing and oxidizing flue gas atmospheres on the ash melting behavior and to assess their importance on the build-up of the initial deposit layers.
Electron beam processing is an efficient technology to reduce emissions of pollutants from flue gases of industrial plants.
MOFC application could increase the efficiency of the boiler, increase the purity of the CO2 in flue gases and reduce energy consumption for the recirculation of CO2.
