Alstom has subsequently transferred this technology to the three major Chinese boiler manufacturers as well as several Design Institutes.
Designed for pulverized coal, B&W's advanced once-through ultra-supercritical boilers are usually applied to systems with a capacity of 400 MW or more. These clean and efficient boilers usually operate at throttle pressures of 3500 psi (24.1 MPa) or more and steam temperatures in the 1100F (595C) range.
However, it agrees with the measurement on a 300 MWe CFB boiler . In the near corner region, heat flux decreases in the corner (<0.5 m). This is because a bed temperature boundary layer was artificially assumed in the calculation. Fig. 4(c) shows the heat flux distribution at the elevation of 52 m. As can be seen, the heat flux profiles on

According to Yue et al., the circulations measured in large CFB boilers are around 6–10 kg/m 2,s at fluidizing velocities in the range 5–6 m/s. These numbers differ from those reported by Wu et al., where the circulation in a 300 MW e CFB boiler operated at 5.4 m/s is 42 kg/m 2,s. The circulation chosen for CLC–CFB is approximately an
coal in steam generating units. However, coal can also be first gasified and then burned as a gaseous fuel. The integration of coal gasification technologies with the combined cycle electric generation process is called an integrated gasification combined cycle (IGCC) system or a "coal gasification facility".
scale-up of Circofluid boilers from 25 to 150 MW. Circofluid boiler designs have also been developed for capacities up to 300 MW. There are other factors, in addition to, cross-sectional area, that influence scale-up. As shown in Figure 2, the boiler portion of the Circofluid system does not differ from a conventional pulverized coal boiler.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also
