Taehwa Engineering Co., Ltd.

TEC has acquired many years experince in the construction of heat exchanger   for flue gases.   TEC heat exchangers have been in succesful as air preheaters and economizers   or for heat extraction.Steam to gas preheaters and static gas preheaters and   heat displacement systems made by TEC give excellent results in reheating   applications behind scrubbers and waste incineration plant.The experince acquired   by TEC guarantees the depanability of its products. Clean gas discharged from wet absorbers (scrubbers) are water vapor   saturated and still contain droplets and residual paticulate matter. These gases   must be dried by reheating before admission into subsquent components or into   the discharge stack. For this purpose, TEC supplies static heat exchangers   as a proven and economical solution. If the SCR facility mounted behind the scrubber, the raw gases must   be reheated tem- perature of approx.300 TEC heat exchangers with high   thermal efficiency dispense in large measure with the need to use external energy   sources. The mian heating is effected via the multi-stage steel tube or counter   flow plain plate type heat exchanger. To prevent corrosion in the cold inlet   zone, the raw gases must be preheated by means of an acid resistant heat exchanger. The energy content of the flue gas can be used at various points in   the flue gas line for energy saving purposes or to increase plant efficiency.   For this purpose, the heat exchanger must satisfy the necessary requirements   in respect of temperature, corron resistance and cleaning capacity on the raw   gas side.
