Packaged boilers are trimmed with necessary safeties and code piping and inspected by authorized, independent code inspectors. Factory mounted and wired packaged, proven and reliable burners are available from all burner manufacturers. Standard burners comply with UL requirements. Code Requirements such as CSD-1, IRI, FM, NFPA85, and CSA are available upon request. Packaged Apache boilers can be factory fire tested to check electrical components for proper operation and ensure smooth ignition and quicker field startups.
For long, trouble free boiler life, it is also vital that combustion be completed within the confines of the firetube. The Apache is designed with a long furnace made with thicker material than ASME requirements. In addition, the furnaces of high pressure steam Apache boilers are corrugated to thwart negative effects of expansion and contraction.
The tube sheet is the most critical component in any scotch marine type boiler and Superior’s tube sheets exceed the ASME code thickness by 25% in low pressure units and 33%in high pressure units. Thick tube sheets coupled with tubes 10%thicker than ASME code requirements and ¾” ligament spacing give Superior Boiler Owners more tube seating surface and long equipment life.
