Since the temperature of the condensed water flowing into the condensed water tank is close to 100°C, and the temperature of the condensed water returned to the boiler generally cannot exceed 80°C, the temperature of the condensed water must drop by at least 20°C during the process of transporting the condensed water from the equipment to the boiler. The condensate tank is an atmospheric tank, which is directly connected to the atmosphere. This part of the heat is directly dissipated from the condensate tank to the atmosphere, which not only causes heat loss, but also causes environmental pollution on the production site.
