Low Emission BoilersAvailable in 3 million and 4 million BTU/hr variations, Vantage offers less than 9 ppm NOX, which can be achieved across all ambient conditions while maintaining ultra-high-efficient operation and full modulation. All models in the boiler series are tolerant of varying system conditions. They include a robust condensing heat exchanger of Duplex alloy steel, which offers corrosion resistance and low thermal expansion rates. Suited for ultra-high-efficiency condensing applications, the hydronic boilers line also includes a model with dual fuel natural gas/propane and natural gas/No. 2 oil capabilities.

Direct -Fired Hot Water Wall BoilersThe 204WW is offered in sizes from 500,000 to 3,120,000 BTU input with a bent tube, all-welded design. All models in the line are designed to fit through a 36" doorway without disassembly. The direct-fired hot water wall boiler is available as straight gas-fired; straight oil; and combination gas/oil with conventional power burner. The L model has a specially designed premix metal fiber burner system for sub-20 ppm NOXlevels. The low NOXmodels are SCAQMD 1146.2 certified and incorporate a variable speed blower. Units are ETL listed as a complete gas fired boiler assembly per UL795.

Biomass Boiler SystemsThe reciprocating grate stoker with automated ash removal, the latest model in the biomass boiler series, offers an efficient multi-fuel design in various configurations. Solid-fuel combustion allows mechanical replacement of fuel with the least number of moving parts. Cast from highest quality steel alloys and mounted on a strong undercarriage system, the boiler can burn wood, coal, bark, construction debris, nuts, shells, husks, paper, cardboard products, hog fuel, sawdust, shavings, sludge or agricultural biomass. The biomass boiler product line’s options include flat-grate stokers, underfeed stokers and traveling-grate stokers to meet all biomass system requirements.

Feedwater heaters maximize exhaust stack heat recovery by recycling waste heat through a single-stage, two-stage, condensing economizer, or on-demand system. According to the company, these methods can increase operating efficiency up to 90 percent and lower overall fuel requirements and energy costs. By burning less fuel, they also result in reduced emissions. The heaters can heat low-temperature makeup or process water as well as deaerated feedwater.

Modular Steam Boilers
Features of the modular boilers include on-demand steam and a reduced environmental footprint. Smaller than their traditional counterparts, modular steam boilers are precision computer-controlled and use natural gas or oil to heat multiple watertubes within a pressure vessel as opposed to heating a large water tank as with older-style boilers. The compact once-through design requires less fuel and water, and yet it produces steam in five minutes or less. The boilers provide BHP outputs comparable to much larger units while reducing fuel costs.

Circulatic incorporates link-free controls and communications capabilities. The controls offer improved combustion, fuel savings and increased reliability due to the elimination of mechanical linkages. Five-minute startup, compact design and full modulation with 10:1 turndown ratios are other features of the steam generator. The company offers boilers up to 600 BHP and 3,200 psi as well as thermal fluid heaters up to 20 million BTU/hr.

Steam Generator for Offshore Oil Rigs
SigmaFire 200 is a 200 BHP steam generator that packs performance into a small footprint. The onboard steam generator can be used to heat drilling mud, a viscous liquid. The “mud” is delivered through the inner ring of a vertical, two-section pipe, to drive and lubricate a drilling head that may be functioning as much as 20,000’ beneath the sea’s surface.
