Case-2Низкотемпературная рекуперация дымовых газов от парового котла на пивзаводе

A 15 mt/hr steam boiler operating at an average load of 10 mt/hr and 7500 hours a year has been equipped with a HeatMatrix polymer air preheater.

An efficiency improvement of 3,3 % (216 kw) was obtained by reducing the flue gas temperature from 130 °C to 69 °C.

The overall pay-back time for this project was 2,3 years.

Flue gas flow 11,700 kg/hr
Flue gas inlet temperature 130 °C
Flue gas outlet temperature 69 °C
Air inlet temperature 20 °C
Air outlet temperature 89,5 °C
