Steam/water circulation design - KTH

riser tubes are situated on the walls of the boiler for efficient furnace wall cooling. The rises tubes are sometimes also called generating tubes because they absorb heat efficiently to the water/steam mixture. The riser tubes forms the evaporator unit in the boiler. After risers, the water/steam mixture goes back to the steam drum.

Heat Exchangers in Boilers - Energiteknik | KTH

In boilers with low steam pressure, the share of the heat needed for evaporation is bigger than when considering a high-pressure boiler. Thus the furnace-wall evaporator cannot provide enough heat for evaporation process in low-pressure boilers. Convection evaporators supply the supplementary heat needed for complete evaporation.
