Flue gas - air preheater for Sugar Company

Engineering, manufacturing and assembling of a heavy weight 79 tons air preheater

The previous heat exchanger was broken after 30 years had to be replaced.

Flue gas - air preheater for Manufacturer of Laminate

Replacement of a flue gas air preheater for a Swiss Manufacturer of Laminate

The previous heat exchanger is corroded due to falling below the dew point and had to be replaced.

Heat recovery capacity through the new plane tube heat exchanger: approx. 670 kW/h

Flue gas - air preheater for Hawaii

Replacement of a flue gas air preheater for a biomass cogeneration plant on Kauai

The previous heat exchanger is corroded due to falling below the dew point and had to be replaced.

The design of the flue gas air preheater was revised by us because of the dew point problem. The subsequent production of the heat exchanger took 12 weeks. The flue gas air preheater was then transported to the port of Hamburg by means of a low-loader truck, where it was packed seaworthy by a specialist company. The shipment took place according to schedule and the heat exchanger arrived at the Pacific port of destination after 10 weeks. The installation was carried out by a US company which was directly commissioned by the power plant operator.

Exhaust-water preheater for biomass cogeneration plant

 Old and residual wood is burned in a biomass cogeneration plant. The combustion takes place in a stationary fluidised bed boiler. Due to the intended use of the energy of the exhaust gas flow after the filter, an additional exhaust gas heat exchanger should be installed as heat recovery. On the water side, the exhaust gas heat exchanger should be operated with district heating water.

For this case of need we supplied a finned tube heat exchanger and newly designed exhaust gas ducts, as well as a corresponding galvanized steel construction to accommodate the heat exchanger. In a planned 2-week plant shutdown, the components were delivered and assembled by us by truck.

Heat recovery capacity through the new finned tube heat exchanger: approx. 1.0 MW/h
