Marspec Technical Products has just installed a new Green Boiler Technologies Immersion Fired natural gas steam boiler at a Florida panhandle chemical plant. The SPB Immersion Fired Series of steam boilers is well known
throughout the industry for its unique single-pass design and burner
technology. Available in both high pressure and low pressure steam, the
single pass immersion firetube design delivers premixed air and gas
through multiple burner nozzles. A corresponding flue tube completely immersed in liquid, is aligned with the nozzle head inside
the combustion chamber. Upon combustion, the nozzles generate a focused,
high velocity flame which radiates down the center of each tube. The
benefits of the technology in the SPS Immersion Fired Series steam
boilers include:
Natural Efficiency
- Up to 82% efficiency
- Radiant heat is maximized across the primary heating surface
Low Maintenance Cost and High Longevity
- Elimination of thermal shock due to balanced heat transfer across primary heating surface; allowing for up to 150° F ΔT
- Backed by a 20-year non-prorated thermal shock warranty
- Elimination of refractory breakdown due to single pass design (no refractory material is used)
Ease of Maintenance
- Hinged door provides quick access to burners, manifold and heating tubes for easy cleaning and routine maintenance
- Trimmed with non-proprietary components
Simplicity of Design
- No complex controls which require intensive training
- Fewer moving parts reduces incidence of failure and required retuning
Low NOx Emissions
- Less than 30ppm NOx
