      A Robust SRU Waste Heat Boiler Design

      In June 1993, the Pine Bend 525 LTPD SRU No.5 was started up using a typical two pass in a single shell Waste Heat Boiler (WHB) design generating nominally 600 psig saturated steam. The WHB first pass used 400 2-1/4” OD SA 213-T11 tubes and the second pass used 400 2-1/4” OD SA 210-A-1 tubes and the inlet tubesheet was 2” thick SA 516-70N.

      Even short-term contamination of the boiler feedwater may lead to corrosion-induced failures within weeks or months, particularly if a boiler system is dirty. Some WHB only recover waste heat, for example from a flue gas convection pass. In such a case, an unscheduled outage caused by a tube leak may not be a critical problem.

    • heat recovery from boiler blowdown tds control only

      Heat Recovery from Boiler Blowdown TDS Control Only

      Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.
