  • Industrial, Commercial, and Institutional (ICI) Boilers

    Direct-contact flue gas condensing removes particles and acid gases (such as sulfur dioxide [SO2]) from exhaust. Recovery of 80% to 90% of heat in the flue gas previously exhausted to the atmosphere is possible, and such a system can reduce fuel consumption by the facility by 50% (Canadian Industry Program for Energy Conservation).Get Price

  • Pressure measurement on steam boilers - industrie.de
