Understanding Boiler Circulation - Cleaver-Brooks - Complete Boiler
1 Oct 2013 Thus, if CR = 8, then x = 1/8 = 0.125, meaning that 12.5% of steam is generated in the evaporator tubes while the rest of the mixture is water. CR may be in the range of 20 to 30 for low-pressure boilers (100 to 600 psig), and about 8 to 15 for higher-pressure units, depending on the design.
How Can We Find The Circulation Ratio In A Heat Recovery Boiler
14 Dec 2016 One of the key issues in the design of Heat Recovery Boilers (HRBs) is the calculation of. the Circulation Ratio (CR). In this paper the circulation
