The York Shipley Global Series 400L and 500L three- and four-pass water-back design accommodates lower BTUH/CF (Mcal/m³) volumetric furnace heat release rates in comparison to competitive water-back configurations. The intermediate tubesheet design reduces vessel thermal stresses.
York Shipley Global water-back boiler employ a low offset furnace with completely submerged self cleaning cylindrical reversing chamber, which permits for scale formation from water bound solids to drift to the bottom of the boiler for removal during blowdown procedures. Fire-side and water-side access is readily provided. Top longitudinal level service platform ensures safe and secure access, while bottom longitudinal inspection trough ensures unencumbered visual access.
Series 400L and 500L Packaged Firetube Boilers
York-Shipley Global offers its packaged firetube boiler utilizing a low-offset furnace design. Series 400L comprising 4SF-FSHS/BHP (.037m² - FSHS/kW), and Series 500L comprising 5SF-FSHS/BHP (.046m² - FSHS/kW), are available as a three-and four-pass, water-back configuration. All steel fireside surfaces are completely water-backed. York-Shipley Global product is supported through an extensive worldwide network of sales, service and regional management representatives.
3W (3-Pass Water-Back)
4W (4-Pass Water-Back)
Liberal Steam Volume
York-Shipley Global’s water-back boiler maintains a larger water volume as well as a larger steam storage space and steam-water interface disengaging area allowing it to maintain performance during swing load operation.
Low-Stress Design
The offset furnace design reduces material stress and thermal NOx production through low heat release rates because of its larger furnace construction and an intermediate tubesheet design which incorporates a fully submerged reversing chamber.
Easy Maintenance
Units include split front and rear fire-side access doors with internal insulation supported by heavy duty pivoting hinge arrangements and protective steel covering. A secure level platform provided on top of boiler prevents casing damage during maintenance and inspection.
Water-Back Design
Completely submerged cylindrical rear combustion reversing chamber construction allows any scale formation from water-bound solids to drift to the bottom of the boiler, to be removed during blowdown maintenance procedures.
