7 Item(s)

  1. e-Tech Box Economizer

    e-Tech Box Economizer

    Our box economizers lower flue gas temperatures by preheating feedwater entering the boiler. The rise in water temperature allows the boiler to produce steam using less fuel, thereby significantly lowering fuel consumption and costs. In general, E-Techers realize a 1% increase in boiler efficiency for each 40°F decrease in flue gas temperature.
  2. e-Tech Circular Economizer

    e-Tech Circular Economizer

    Space-saving design for smaller boilers (100-1200 hp) and confined spaces.
  3. e-Tech Condensing Economizers

    e-Tech Condensing Economizers

    Low-grade heat transfer without damaging corrosion. While traditional boiler economizers recover sensible heat from a flue gas stream, condensing units go a step further. Each 1,000,000 Btu of methane contains more than 91,000 Btu of water vapor, latent heat that represents 9% of the beginning fuel content. Cooling exhaust gas below its dew point with an E-Tech condensing heat exchanger can recover the bulk of this otherwise wasted energy. Depending upon conditions, it is possible to reach combined combustion efficiencies greater than 96%.
  4. e-Tech HRSG Economizer

    e-Tech HRSG Economizer

    Steam turbine-driving units custom-engineered for your needs. E-Tech combines its long-life economizers with equally dependable evaporator, feedwater heater, and superheater components in custom heat recovery steam generators. Our engineers will custom-design your HRSG unit, taking into consideration the specific operating requirements of your plant and steam turbine-driving needs in a single, fully assembled package. We can also apply supplemental components as needed for your particular application.
  5. e-Tech In-stack Economizer

    e-Tech In-stack Economizer

    The ideal application when space is scarce.
  6. e-Tech Modular Economizer

    e-Tech Modular Economizer

    A compact solution for big cost-savings. Our modular economizers apply our precise engineering and demanding quality controls to yield outstanding efficiency in a single unit with low-, intermediate- and high-pressure sections. This feature allows for easier installation due to the compact size.
  7. e-Tech Process Heaters

    e-Tech Process Heaters

    Direct-fired heaters ranging from 0.5-50 mm Btu/h. E-Tech direct-fired heaters are designed to meet the thermal needs of your system while minimizing fuel usage. Our engineers specialize in the design of two types of high efficiency direct-fired heaters: vertical cylindrical heaters for smaller applications and horizontal cabin heaters for larger ones. We use top-of-the-line burners that can be fueled by natural gas or oil, and that minimize NOx and CO2 emission levels. Our long-life units can be engineered precisely to your size and space requirements.
