7.3 Heating System Steam is injected directly into the chamber sump to heat the recirculating cleaning solution The steam assembly contains the following components: • One (1) Steam sparger assembly − Duty: See Table 6: Direct Steam Injection Performance − Material: 316ss with welds color cleaned − Insulation: None − Design: Direct steam injection − Rating: Non-ASME − Connections: Tri-clamp (sump connection), MNPT (steam connection) • Steam supply piping manifold constructed of uninsulated SCH 40 304ss socket weld pipe and fittings − One (1) Pressure gauge with 0-100 psi range anti-siphon and manual block valve
− One (1) Steam strainer with manual blow-down valve − One (1) On/off ball valve with pneumatic actuator − One (1) Check valve
