CERTUSS TECHNOLOGY

With 14,000 installations in over 130 countries, CERTUSS has built a reputation for safety and reliability worldwide. CERTUSS’ controlled circulation, once through watertube pressure vessel design, commonly referred to as a “steam generator”, is ASME rated up to 460 psig MAWP for every model CERTUSS builds. Thermal shock proof pressure vessel design means it can be fired “on-demand”, and can accept quick steam load changes without concern for damage. Ultra low operational water volume, a significant operational safety factor in generating high pressure steam, contributes to quick start times of 3-5 minutes from cold steel, and rapid responsiveness to varying steam loads. Further, the low water volume results in a very compact footprint for the respective steam capacity, especially compared to tubeless, and firetube boiler designs.

Unique air cooling of the outer jacket, which also serves to pre-heat combustion air, results in minimal radiant losses to ambient, and boosted combustion efficiency, resulting in 87% fuel-to-steam boiler efficiency, without the implementation of an optional flue gas economizer (by others). Optional Flue Gas Recirculation (FGR) contributes to reduced NOx.

CERTUSS boilers are all ASME stamped, and when purchased as a complete system, combining boiler, piping, wiring, and CVE accessory skid, provide the customer with UL certification not only for the boiler, but the entire system. Further, every CERTUSS system that leaves the factory has been fully pre-commissioned, testing and certifying the entire system before it arrives at the customer’s facility.

The functional principle

By using the water tube boiler principle, the CERTUSS technology for generating steam offers maximum safety, reliability and instant availability of high quality steam.

  • The touch screen control panel simplifies operation and control of the boiler. All system configurations and settings of steam pressure are made here.
  • The pre-heated feed water is delivered to the boiler at approx. 195°F to 205°F. The heat frees the oxygen from water and reduces the risk of oxygen corrosion.
  • The boiler pressure coil is supplied with water through the feed water inlet. The change of phase from water to steam begins.
  • Two-stage integral burners provide precise pressure control, avoiding large swings due to purge cycles, and via full burner modulation.
  • Insulation material is made obsolete by guiding the combustion air from the top of the boiler through an outer shell, and from there into an inner, secondary shell, before delivering pre-heated air to the burner. This unique approach maximizes efficiency not only through increased combustion efficiency, by also by sharply minimizing radiant losses from a shell that remains only warm to the touch at maximum capacity.
  • When the steam has been produced, it leaves the generator through the steam outlet and is then ready for use.
  • The flue gas outlet connects to the chimney with or without an optional economizer.
  • Sediment is flushed out through the pressure coil blow-down valve. The safety relief valve opens automatically to discharge excess steam if the pressure is too high.
Advantages
  • Quick start time of 3-5 minutes to reach full rated capacity
  • Standard thermal efficiency of up to 87% as a result of unique combined air insulation/combustion air pre-heating design
  • Significant space savings compared to vertical and horizontal tubeless/firetube designs
  • Maximum operational safety intrinsic to the design of the ASME stamped pressure coil minimizes risk to personnel and property
  • Fully automated, pre-programmable system operation via CERTUSS Thermotimat control – start up, shutdown, and blowdown
  • Optional automated short-term cold standby “preservation mode” for safe shutdown over weekends, or more
  • Reduction in field-labor costs for installation due to easy reassembly of pre-piped & pre-wired system components
  • Single-source, full steam boiler system solution, completely UL certified, and pre-commissioned prior to shipment
  • Fuel options include low pressure natural gas, propane, and #2 oil, as well as a dual fuel combination of natural gas/#2 oil (Universal TC)
  • Robust, all steel construction
  • Modular construction and quick steam production results in high performance system response from multiple boilers, as well as N+1 redundancy with less installed horsepower, and a smaller footprint.
  • High performance responsiveness to a wide range of steam demands
  • Minimal pressurized water maximizes personnel/property safety
  • Warm-to-the-touch air-cooled shell, even at maximum steaming capacity for increased personnel safety and lower ambient temperatures
  • Minimal and basic maintenance required, with spare parts available up to 20 years
  • Customer commitment, both from the factory and local representatives
