Quality

To make the highest quality scotch marine boiler on the market, we began with quality-in-design. The tube sheet, tube and furnace and other critical parts were designed above the minimum code to guarantee a quality design that will last for decades.

The tubesheet is the most critical component in any scotch marine type boiler and ZHONGYUAN’s tubesheets 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 ZHONGYUAN Boiler Owners more tube seating surface and long equipment life.

For long, trouble free boiler life, it is also vital that combustion be completed within the confines of the firetube. The Super Seminole is designed with a long furnace made with thicker material than ASME requirements. In addition, the furnaces of high pressure steam Super Seminole boilers are corrugated to thwart negative effects of expansion and contraction.

Our employees unite each and every day to seek quality in workmanship. Whether we are cutting steel, welding tubesheets to pressure vessels, insulating pressure vessels with two inch 8-lb density mineral fiber, painting galvanized 22 gauge steel jackets with 500°F enamel or piping a gas train, we tailor our products to exceed ASME standards.

Safety

Packaged boilers are trimmed with necessary safeties and code piping and inspected by authorized, independent code inspectors. Factory mounted and wired packaged burners with mounted gas trains complete with main gas pressure regulators are available from all burner manufacturers. Standard burners comply with UL requirements. Code requirements such as CSD-1, IRI, FM, NFPA 85, and CSA are available upon request. Packaged Super Seminole boilers can be factory firetested to check electrical components for proper operation and ensure smooth ignition and quicker field startups.

Exceptional Value

ZHONGYUAN Boilers offer thicker tubesheets, thicker tubes, large corrugated furnaces, and the ability to factory mount, wire and test UL or CSA listed burners from all burner manufacturers. However there are still more features that make the Super Seminole an exceptional value. All Super Seminole boilers have two 3” x 4” handhole openings in the front tube sheet, two handholes on the bottom centerline and an available manway which permits inspection of the bottom of the drum, and facilitates cleaning and tube removal. Full front end and fireside access is standard on all ZHONGYUAN Boilers. Our design eliminates the necessity of disconnecting fuel lines when inspection or maintenance functions are required.
