header that served paper machine #3. In addition, the boiler room 40 psig steam header vented approximately 2,000 lbs of steam per hour. The assessment showed that if these headers were connected, the steam currently being vented could supply the paper machine. This would lower the mill's total steam load and yield natural gas savings ofTaking all things into account, the most costeffective heating options, over the full service life of the autoclave, will be either a highpressure steam boiler or gasfiring using an internal or external heat exchanger. Cooling. Cooldown at the end of the process cycle requires a means of
highpressure steam. The assessment estimated that this measure would increase the ammonia plant's efficiency by 0.4% and thereby lower highpressure steam demand by approximately 20,000 lb/hr. Energy savings were estimated at 0.4 MMBtu per ton of output, yielding estimated annual natural gas savings of 274,000 MMBtu.Loion: 8600 Rockville Pike, Bethesda, MD
The yield of each steam generator indies the percentage of calories produced by burning and recovered as steam. With an 80 percent yield, the kilocalories actually available for steam production are: The total heat produced by vaporization of one kg of steam at 170°C at a pressure of 8 kg/cm 2 is 660 kcal. However, assuming the water comesENERGY CONSIDERATIONS FOR STEAM PLASMA GASIFICATION OF BLACK LIQUOR AND CHEMICAL RECOVERY (see Figure 3).

The wasteheat boiler can produce steam with pressures ranging from 30 to 100 bar. This steam can be used to drive the processair compressor of the secondary reformer or can be fed to the internal high pressure steam network.
2013 Revisions to the Greenhouse Gas Reporting Rule (PDF) to 40 CFR part 98, subpart C: Table C–1 to Subpart C—Default CO2 Emission Factors and High Heat Values for Various Types of Fuel and Table C–2 to Subpart C—Default CH4 and N2O Emission Factors for Various Types of Fuel.A steam boiler plant must operate safely, with maximum combustion and heat transfer efficiency. Lowlevel alarms will draw attention to low boiler water level and, if required, shut down the boiler. Highlevel alarms protect plant and processes. The operation and benefits of 3 different types are considered here liquid expansion traps
All the tests performed were undertaken on boiler No. 2. The No. 2 boiler was a small 18,000 Ib/hr (8,200 Kg/hr), 150 psig (103.4 N/cm2), saturated steam boiler equipped with a chaingrate stoker. The boiler has no heat traps, superheaters, or pollution equipment.
