00:00:00.000 boilers and thermal liquid heater 00:00:01.79000:00:01.800 generate heat for use in other 00:00:03.37900:00:03.389 operations they differ in the fluid 00:00:06.17000:00:06.180 medium used to transfer this heat the 00:00:09.35000:00:09.360 industrial boilers shown is used for dry 00:00:11.95900:00:11.969 cleaning steam boilers heat water to 00:00:14.99000:00:15.000 produce steam which is then used to 00:00:16.84900:00:16.859 generate energy or heat for other 00:00:18.71000:00:18.720 processes water is converted to steam in 00:00:22.37000:00:22.380 the boiler this steam travels through 00:00:25.07000:00:25.080 the heating apparatus which can be any 00:00:27.38000:00:27.390 piece of equipment that requires steam 00:00:29.87000:00:29.880 for operation the cooled steam is then 00:00:32.74900:00:32.759 condensed into water the returns to the 00:00:34.88000:00:34.890 boiler to start the cycle again 00:00:38.66000:00:38.670 there are three main types of steam 00:00:40.54900:00:40.559 boilers fire tube water tube and cast 00:00:43.52000:00:43.530 iron in fire tube boilers the combustion 00:00:46.97000:00:46.980 gases travel within the tubes to heat 00:00:49.85000:00:49.860 the surrounding water in water tube 00:00:53.06000:00:53.070 boilers the water travels inside the 00:00:55.40000:00:55.410 tubes cast-iron boilers are similar to 00:00:58.72900:00:58.739 water tube boilers but the water is 00:01:01.00900:01:01.019 contained in cast iron sections instead 00:01:03.38000:01:03.390 of in tubes 00:01:05.22000:01:05.230 all steam boilers have four independent 00:01:07.83000:01:07.840 systems the feedwater system supplies 00:01:11.01000:01:11.020 water to the boilers the fuel system 00:01:13.26000:01:13.270 transports the fuel the draft system 00:01:15.90000:01:15.910 controls air flow for fuel combustion 00:01:18.48000:01:18.490 and the steam system collects and 00:01:20.73000:01:20.740 controls the produced steam the most 00:01:23.55000:01:23.560 commonly used fuels are coal natural gas 00:01:26.52000:01:26.530 and oil most fire tube boilers are 00:01:29.82000:01:29.830 portable and are used in oil fields 00:01:32.12000:01:32.130 sawmills and that construction sites to 00:01:35.10000:01:35.110 generate heat or power water tube and 00:01:38.04000:01:38.050 cast-iron boilers may be solid fuel 00:01:40.47000:01:40.480 fired or they may operate on standard 00:01:43.11000:01:43.120 liquid and gas fuels the water tube 00:01:46.23000:01:46.240 boiler at Wright operates on gas fuel 00:01:48.63000:01:48.640 and is part of a cogeneration plant 00:01:51.15000:01:51.160 where heat from the fuel is 00:01:53.04000:01:53.050 simultaneously converted into electrical 00:01:55.47000:01:55.480 and thermal energy 00:01:59.51000:01:59.520 water and fuel the only to feed for this 00:02:02.63000:02:02.640 type of boiler our abundant and 00:02:04.60900:02:04.619 inexpensive it can handle large 00:02:07.28000:02:07.290 capacities and high pressure but it 00:02:10.13000:02:10.140 corrode during shutdown periods and 00:02:12.22900:02:12.239 water must be treated to prevent buildup 00:02:14.58900:02:14.599 there is always some heat loss water 00:02:18.55900:02:18.569 heat boilers have immense size as shown 00:02:20.92000:02:20.930 environmental and economic concerns 00:02:23.12000:02:23.130 promoted the development of a boiler 00:02:25.16000:02:25.170 that ruses byproducts waste heat boilers 00:02:28.72900:02:28.739 recycle the heat steam or combustible 00:02:31.13000:02:31.140 byproducts of other processes to provide 00:02:33.53000:02:33.540 energy because of their unconventional 00:02:35.30000:02:35.310 fuel source waste heat boilers have a 00:02:38.27000:02:38.280 unique design waste heat boilers 00:02:41.18000:02:41.190 generally have large intake capacities 00:02:43.46000:02:43.470 than other types of boilers because the 00:02:45.80000:02:45.810 entering fuel is not very efficient the 00:02:48.22900:02:48.239 way steam or other fuels enter through 00:02:50.47900:02:50.489 the inlet duct and travel to the reader 00:02:52.37000:02:52.380 where any combustible material is burned 00:02:55.09000:02:55.100 the resulting gases travel through a 00:02:58.07000:02:58.080 series of high and low pressure tubes to 00:03:00.97900:03:00.989 heat the water held in the reservoirs 00:03:02.94900:03:02.959 the resulting steam exits through the 00:03:05.99000:03:06.000 outlet stack 00:03:10.25000:03:10.260 waste heat boilers are used in many 00:03:12.50000:03:12.510 industries in steel mills two furnaces 00:03:15.83000:03:15.840 supply heat to one boiler energy sources 00:03:19.61000:03:19.620 are recovered from diesel engine exhaust 00:03:21.92000:03:21.930 or refineries and cement kilns these 00:03:25.30900:03:25.319 boilers are also common in the paper and 00:03:27.55900:03:27.569 wood industries this photograph shows 00:03:30.41000:03:30.420 four waste heat boilers used in a 00:03:32.80900:03:32.819 repowering project in Las Vegas the 00:03:35.72000:03:35.730 boilers process the waste fuel from 00:03:38.00000:03:38.010 adjoining processes it recycle waste and 00:03:41.63000:03:41.640 good for the environment and business it 00:03:44.38000:03:44.390 depends on other processes for fuel and 00:03:47.36000:03:47.370 heat byproducts of other processes are 00:03:50.44900:03:50.459 not the most efficient combustible fuel 00:03:52.84900:03:52.859 sources and therefore waste heat boilers 00:03:55.67000:03:55.680 are less efficient than other types of 00:03:57.58900:03:57.599 boilers 00:03:59.56000:03:59.570 thermal liquid heater are similar to 00:04:02.24000:04:02.250 other boilers in that heat is generated 00:04:03.98000:04:03.990 for use in a remote application in 00:04:06.52000:04:06.530 thermal liquid heaters 00:04:08.57000:04:08.580 however fluids other than water transfer 00:04:11.33000:04:11.340 the generated heat thermal liquid 00:04:14.18000:04:14.190 heaters are usually liquid tube boilers 00:04:16.27000:04:16.280 comparable to water tube steam boilers 00:04:19.01000:04:19.020 the most common heat sources are gas and 00:04:22.64000:04:22.650 oil fuels and electricity 00:04:25.82000:04:25.830 thermal liquid heater are better than 00:04:28.26000:04:28.270 steam boilers if process operates near 00:04:31.17000:04:31.180 or below the freezing point of water or 00:04:33.33000:04:33.340 above 700 degree fahrenheit thermal 00:04:37.08000:04:37.090 fluids typically do not transfer heat as 00:04:39.66000:04:39.670 well as water serious containment 00:04:42.51000:04:42.520 problems with thermal fluids at high 00:04:44.31000:04:44.320 temperatures including corrosion erosion 00:04:47.28000:04:47.290 and freezing other problems with 00:04:49.98000:04:49.990 toxicity explosiveness and order Thermal 00:04:54.15000:04:54.160 liquids and equipments are expensive
