  • Exhaust Gas Boilers And Economisers for Marine Machinery

    As for ship design, the maximum waste heat recovery is desirable. For exhaust gas economisers, the funnel stack temperature must be as low as possible but with sufficient margin to be above the dew point to avoid sulphur corrosion. Generally a funnel temperature of 165 to 195 deg C when using fuel oil is considered optimum.Learn More

  • Condensing boilers | Jeremias® Exhaust Systems

    The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply. The exhaust gasses are cooler and hence the maximum condensing happens in the chimney. The condensate then flows along the internal wall of the pressure-tight pipe, and back to the boiler for disposal.Learn More
