XXL Size Recovery Boilers - Valmet

May 24, 2017 · 3.5 kg steam/kgds. Steam generation in high-power boilers is easily higher than 4.0 kg steam/kgds and for example in Äänekoski's new recovery boiler, this ratio is 4.35 kg steam/kgds. If the new boiler had traditional recovery boiler features with the same black liquor load, then its steam generation would be 7200 tds/d x 3.5 = 292 kg/s.

Steam Heating Process - Load Calculating

In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).
