A heat exchange cooling system for an internal combustion engine co-generation plant, which allows exhaust recycled gas combustion while maintaining lower head temperatures to reduce thermal NOx emissions while delivering increased processutility heat to a proximate co-generation client, is provided. Categorized sets of signals are processed, and an accuracy for each set calculated. Each of the first and the second data read-out controllers comprises a first read-out switch, a second read-out switch, a first sampling unit, and a second sampling unit. In some embodiments, a proximal section of the tubular member may include a plurality of slots defined therein, for example, that may be configured to increase the lateral flexibility of the tubular member. The main portion of the exhaust air from the air space of the hood is supplied via this second heat recovery tower and out from the drying section.
