Condensate recovery system can be divided into open and closed recovery system recovery system.

Recovery system is open to a condensate recovery tank to the boiler, the condensed water recovery and utilization in the process, one end of the recovery pipe is open to the atmosphere, i.e., the condensed water collection tank is open to the atmosphere. When the lower pressure of the condensed water, can not be reached by the pressure from recycling properties, high temperature condensed water pump pressure-feeding. The advantage of this system is that the device is simple, easy to operate, a small initial investment; however, a large area of ​​the system, resulting in low economic efficiency, larger environmental pollution, and since the condensed water is directly in contact with the atmosphere, dissolved oxygen concentration in the condensed water improved, easy to produce equipment corrosion. This system is suitable for small vapor supply systems, a small amount of condensate, small amounts of secondary steam system. When using this system should minimize emissions of secondary steam.

Hot water water pretreatment for high pressure boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
