EXERGY AND ECONOMIC ANALYSIS OF DUAL PRESSURE WASTE HEAT RECOVERY BOILER 1UMIT GUNES, 2ASIM SINAN KARAKURT Abstract-Waste heat recovery systems (WHRS), uses exhaust gas in the boiler, are very important in terms of increasing energy efficiency and reducing green gas emissions. Due to this reason, WHRS get more importance. Although dual pressureLearn More
The Aalborg XW-TG can be arranged in many different configurations, e.g. for a single pressure or dual pressure system, according to each individual requirement for steam and power output. The economizer can be supplied with a dividing wall system for connection of several exhaust gas sources to one boiler.Learn More
A dual pressure boiler system has a bottom furnace that operates as a low pressure natural circulation steam generating system and a top furnace that operates as a high pressure natural circulation steam generating system. The low pressure natural circulation steam generating system his a low pressure steam drum, a first pump for providing feed water to the low pressure steam drum, and a low Learn More

Sep 01, 2001 · Dual-bed CO 2 adsorption using zeolite was studied experimentally and theoretically. Boiler exhaust gas (13 vol% CO 2, 79 vol% N 2 and 8 vol% O 2) was used as a feed gas for the eight-step four-bed PSA process.Na-X type zeolite (NaX) and Na-A type zeolite (NaA) were selected in the break-through test. NaX has higher CO 2 adsorption capacity than other adsorbents.Learn More
