You need to install the Flash Player to view the slideshow on this page

Exhaust Steam Generator 1 (ESG1 Series)

The fully packaged ESG1 is selected from 48 pre-engineered standard models with output capabilities of 20 to 500 Boiler HP and operating steam pressures from 3 to 450 PSIG. The ESG1 is shipped complete, ready for operation as either a primary or supplementary steam source. The ESG1 package is made up of three basic sections: finned tube heat transfer section; steam flash circulating drum assembly; modulating full port exhaust bypass system.

The water pump continually circulates high temperature water from the steam flash drum assembly to the heat transfer core assembly. BTU is transferred from the exhaust to a high-flow superheated water and steam mixture. The superheated water is returned to the steam drum which contains dry pipe, baffles, and lance assemblies, where it flashes into 99% dry steam as it exits out to the system.

Combustion Capacity: 400kW to 7MW

Entering Gas Temperatures: 600°F to 1600°F


  • Self-contained "package" reduces installation, and maintenance costs
  • Half the weight and floor space of conventional boilers, reduces building and shipping costs
  • Tube replacement requires no cranes, crews, or extra roof height above the unit
  • Produces 99% dry steam
  • 100% turndown capabilty
  • 5-10 minute startup to full output
  • modulating exhaust bypass for safe automatic steam control
  • explosion-proof heat transfer exchanger
  • low friction loss for minimum static exhaust back pressure
  • High circulating flow to minimize scale buildup
  • No thermal expansion concerns with cold boiler feedwater
  • lowest pinch point in the industry
