Cogen Applications
  • Hospitals
  • Manufacturing Plants
  • Schools
  • Office Buildings
  • Shopping Malls
  • Drilling Platforms
  • Oil & Gas Plants
  • Marine
  Equipment Variety
  • Exhaust Steam Generators
  • Large Exhaust Recovery Silencers
  • Smaller Specialized Exhaust Recovery Silencers
  • Special Heat Transfer Configurations
  • Recirculating Engine Jacket Water Boilers

System Function
BTU is transferred from the exhaust stream to heat sinks such as water, glycol, therminol fluids, or steam production. Suitable fuel types for combustion sources include natural gas, propane, digester gas, diesel fuel, and light to heavy fuel oils.

Proposal Considerations
  • Large or Irregular Exhaust Connections
  • High or Varying Exhaust Temperatures
  • Particular Pinch Point Requirements
  • Exhaust or Liquid Control
  • Special Heat Sink Requirements
  • Special Heat Transfer Metallurgy Requirements
  • Specific Maintenance Concerns
  • Optional Equipment Requirements
  • Installation Space and Weight Concerns
  • Package System Requirements
Anticipated Results
  • Tremendous fuel savings typically pay for equipment and installation within 1 to 3 years of average use.
  • Pollution reduction due to lowered annual fuel usage.
  • Lower exhaust temperatures and significantly reduced sound output levels (final sound attenuation is typically 15 - 25 dBA).

Ebullient Steam Generators from Engine Jacket Water
The Exhaust Cooling Steam Generator (ECSG) as designed to produce low pressure steam (15 PSIG and under) from engine jacket water via natural circulation. They are available in a variety of tank sizes for horizontal or vertical installations. Standard design includes: ASME stamped steam flash tank built in accordance with Sec.VIII Div.I; shipped as a packaged unit including continuous water level feed control with low water cutoff, auxiliary low water cutoff, excess steam pressure switch, gauge glass assembly, surface and main blowdown assembly, vent valve, steam safety valve, steam pressure gauge, wall or floor mount. Basic customer connections for ease of installation include: 150# steam outlet, 150# water outlet, 150# water/steam inlet, NPT Blowdown, and NPT Boiler feedwater. The unit shall be pre-piped and wired for a single 120v 1ph 60hz customer power connection.

Boiler Feedwater Tank Assembly
Cain Boiler feedwater systems are available in a variety of tank sizes, feedwater pump configurations, and optional water treatment assemblies. Packaged assemblies include: heavy wall tank as mounted on a 5' high rectangular tube structural steel stand with water level controls and low water cutout, gauge glass and thermometer, magnesium anode; (2) 2" NPT vents; 2" NPT condensate return; 1" NPT drain with shut off valve; Duplex or Triplex boiler feedwater pump system; electrical control panel fully pre-wired with fused disconnect switches, magnetic starters, manual start-stop switches and indicating run lights for feedwater pumps and alarms; all interconnecting wiring from electrical control panel to each component, optional chemical feed system, and/or automatic water softening system; all interconnecting bypass piping, valves, gauges, fittings, etc. Primed, painted, and tested package is a complete, properly functioning assembly, ready for the customer’s primary connections of water, condensate return, and electricity.

Our Uniquely Designed Exhaust Gas Bypass Valves
Cain Industries offers total exhaust gas control with high temperature modulating bypass and shut off valves. The valve assemblies offer precise exhaust temperature control and/or the design capability for exhaust isolation. Sizes ranging from 4" to 40" diameter are available in carbon steel and stainless steel for all engine temperatures. All valves are available with either electric or pneumatic control actuation and emergency fail safe features.
