SECTION VI - TECHNICAL SPECIFICATIONS

6.1 GENERAL The following pages contain Tables with general reference information intended to assist in the installation of your Clayton SigmaFire steam generator. The information is provided only for standard Clayton thermal products. Specially designed equipment, such as Clayton Steam Generators with Low NOx Burners, are addressed in Supplemental Instructions. 6.2 AGENCY APPROVALS All standard SigmaFire steam generators are designed and built to meet ANSI, ASME, Boiler Pressure Vessel Code Section I, ASME CSD-1, IRI /GEGAP, FM, UL, CUL, and CRN requirements. The marine listings ABS, USCG, DNV, and CCG, are available. 6.3 CONSTRUCTION MATERIALS Only high quality materials are used in the manufacturing of the Clayton Steam Generator. The Heating Coil in the generator is manufactured by Clayton using ASME SA178 or SA192 steel tubing. All welds are performed by Clayton ASME certified welders. The coil is then hydrostati- cally tested to 1.5 times the design pressure or 750 psig (52 bars) which ever is greater. The coil is encased in a mild steel jacket that contains all combustion gases. The steam separator shell is constructed of SA53 seamless black pipe. The heads are made of ASME SA 285 carbon steel. The separator also has openings for steam safety relief valves. 6.4 FLAME SAFEGUARD Combustion safety control is accomplished by an Electronic Safety Control (ESC) flame monitor- ing system. The ESC is a microprocessor-based, burner management, control system designed to provide proper burner sequencing, ignition, and flame monitoring protection. In conjunction with limit and oper- ating controls, it programs the Burner, Blower Motor, ignition, and fuel valves to provide for proper and safe burner operation. The control monitors both pilot and main flames. It also provides current operating status and lockout information in the event of a safety shutdown. The programmer module, a component of the ESC, provides functions such as pre-purge, recy- cling interlocks, high-fire proving interlock, and trial for ignition timing of the pilot and main flame. Burner flame is monitored by a flame sensor mounted in the Burner Manifold Assembly. The flame sig- nal is sent to the amplifier module in the ESC. An optional display module may be added to provide read- outs of main fuel operational hours and the flame signal.
