求翻译：锅炉蒸汽的蒸发器被原料水吸收热量冷凝后，凝结成锅炉蒸汽凝结水，作为预热器的加热热源，预热的原料水最后从预热器不凝结水排水口排出。是什么意思？

Steam boiler evaporator is absorbed by the raw-water heat condensation, condensed into the boiler steam condensate, as the the preheater heating source, the preheating of the raw-water last condensation water outlet from the preheater is not discharged.

The boiler steam is raw water evaporator condensate, absorb heat boiler condenses the steam condenses into water, as a warm-up, the heat source to warm up the raw water from the condensation water is not warm water discharge.

After the boiler steam evaporator by raw material water absorption quantity of heat condensation, congeals the boiler steam condensing water, as the pre-heater heating heat source, the preheating raw material water finally does not discharge from the pre-heater condensing water freeing port.

Boiler steam evaporator after absorbing heat by raw water condensation, condensation steam condensate as boiler, as preheater of heating heat, warm raw water condensate drain not draining from the preheater.
