00:00:08.049 00:00:08.059 Sumitomo shi fw is advancing steam
00:00:11.839 00:00:11.849 generation technology with its
00:00:13.699 00:00:13.709 state-of-the-art circulating fluidized
00:00:15.439 00:00:15.449 bed technology due to its fuel flexible
00:00:18.439 00:00:18.449 low-temperature burning process cfb
00:00:21.259 00:00:21.269 technology can utilize all types of
00:00:23.570 00:00:23.580 colds late nights petroleum coax and
00:00:26.269 00:00:26.279 carbon neutral fuels like biomass and
00:00:28.730 00:00:28.740 recycled waste to produce clean and
00:00:31.220 00:00:31.230 economical power generation it offers a
00:00:33.889 00:00:33.899 major advantage over the limitations of
00:00:36.020 00:00:36.030 conventional combustion the ability to
00:00:38.360 00:00:38.370 burn the widest range of fuels
00:00:40.750 00:00:40.760 conventional coal technology requires
00:00:43.279 00:00:43.289 the fuel to be finely ground and dried
00:00:45.740 00:00:45.750 before entering the furnace these steps
00:00:48.290 00:00:48.300 are not needed for the cfb instead the
00:00:51.560 00:00:51.570 fuel is coarsely crushed and dropped
00:00:53.630 00:00:53.640 into fuel chutes which lead to ports in
00:00:55.880 00:00:55.890 the lower section of the CF B's furnace
00:00:58.329 00:00:58.339 unlike conventional boilers that burn
00:01:00.889 00:01:00.899 the fuel in a massive high temperature
00:01:03.110 00:01:03.120 flame cfb technology utilizes
00:01:05.810 00:01:05.820 circulating hot solids to cleanly and
00:01:08.210 00:01:08.220 efficiently burn the fuel in a flameless
00:01:10.400 00:01:10.410 combustion process it's low uniformed
00:01:13.310 00:01:13.320 combustion temperature minimizes the
00:01:15.380 00:01:15.390 formation of nitrogen oxides and allows
00:01:17.690 00:01:17.700 the injection of limestone to capture
00:01:19.670 00:01:19.680 acid gases as the fuel burns giving the
00:01:22.700 00:01:22.710 CF be the lowest furnace emissions since
00:01:25.730 00:01:25.740 the fuels ash doesn't melt heat transfer
00:01:28.400 00:01:28.410 surfaces stay clean allowing the hot
00:01:30.560 00:01:30.570 solids to conduct their heat efficiently
00:01:32.720 00:01:32.730 throughout the entire boiler while
00:01:34.400 00:01:34.410 fouling and corrosion are minimized the
00:01:37.130 00:01:37.140 payoff low plant emissions low
00:01:39.620 00:01:39.630 maintenance and high plant reliability
00:01:43.990 00:01:44.000 to achieve very high combustion
00:01:46.670 00:01:46.680 efficiency for all fuels the solid
00:01:49.070 00:01:49.080 particles in the furnace are collected
00:01:50.900 00:01:50.910 by steam cooled solid separators which
00:01:53.660 00:01:53.670 recycle most of them back to the furnace
00:01:57.039 00:01:57.049 before re-entering the furnace the
00:01:59.390 00:01:59.400 particles pass through a high
00:02:00.740 00:02:00.750 performance in Trek's heat exchanger
00:02:02.749 00:02:02.759 where steam coils are submerged in a
00:02:04.880 00:02:04.890 bubbling bed of hot solids to
00:02:06.649 00:02:06.659 efficiently produce high temperatures
00:02:08.479 00:02:08.489 superheat steam to further reduce plant
00:02:11.600 00:02:11.610 operating costs and emissions our CF
00:02:13.850 00:02:13.860 bees can utilize vertical tube
00:02:15.559 00:02:15.569 supercritical steam technology to
00:02:17.660 00:02:17.670 achieve the highest plant efficiency and
00:02:19.670 00:02:19.680 for full capture of greenhouse gas
