ENGINEERING MANUAL Industrial Boilers

Hot water boilers are normally used in room and process heating. This kind of system is suitable for discharge temperatures up to 140°C. The advantage of hot water over steam is that energy loss is lower than with steam boilers. 2. Thermal oil boiler In hot oil boilers is used oil in stead of steam or water. The advantage with oil is that the
