Packaged firetube boiler assemblies incorporating three- and four-pass, centerline furnace, down-draft, dry-back technology and rated at nominal 4SF-FSHS/BHP (.037m² - FSHS/kW). Capacities available from 30 to 1,300 BHP (294 to 12,743 kW) at standard design pressures of 15 to 300 PSIG (103 to 2,068 kPa).
Due to its economical and compact profile, the Y-SG Series 400C is particularly suited for continuous operation where stable process and space heating load demands are available. Moderate furnace heat release rates assure reduced vessel stress and thermal NOx production. Centerline furnace accommodates uniform vessel stress.
