The deaerator is one of the key equipment in the boiler and heating system. It is mainly composed of the deaerator tower head, the deaerator water tank, as well as the connecting pipe, and the external parts. If the deaerator's deoxidizing ability is poor, it will cause serious corrosion to the boiler's water supply pipeline, economizer, and other ancillary equipment, and the economic loss will be dozens or even hundreds of times the cost of the deaerator. Everyone must pay attention to the quality selection of deaerators.

In the system of oil-fired and gas-fired boilers, the condensing heat exchanger is the corresponding waste heat recovery and utilization equipment installed at the end of the boiler. If the flue gas is around the heat transfer surface, the corresponding near-wall surface temperature will gradually drop to the dew point temperature, which is accompanied by the cooling and condensation process of the water vapor, thereby releasing the corresponding heat and conducting the heat to the interior through the heat transfer surface. The specific working fluid is used, and then the heat in the exhaust gas is collected again, so as to achieve the purpose of energy saving and environmental protection of the system.

The boiler regularly discharges sewage or waste hot water whose pressure is higher than that output by the regular blowdown expander and separates secondary steam and waste hot water through decompression and expansion. The secondary steam can be discharged into the atmosphere or used as a heat source, and the waste hot water is generally discharged into the sewer system through the sewage cooling pool. In this way, the recovery of secondary steam and waste hot water can be used as a heat source, and a part of the heat loss caused by the boiler blowdown can be recovered, and the efficiency of the boiler can be improved.

The deaerator pump needs to be used in conjunction with the deaerator in order to play a good deaeration function in the boiler equipment. Generally speaking, the selection of the deaerator pump should not only combine the flow-head curve, but also simulate the working curve after parallel connection through a certain selection software, and also leave a certain margin. Therefore, in the two When the deaerator pumps are connected in parallel, 5-10% of the space can be reserved according to experience, which requires the boiler engineer to have certain technical experience.
