Brief:This device mainly consists of five parts: a liquid metering pump system, a dissolution and preparation system, a metering and dosing system, a safety system, and a control system.
Hydrazine is drawn into the metering system via a water ejector, then added proportionally to the dissolution and mixing system with demineralized water or condensate, and finally added to the boiler feedwater via the metering and dosing system. Dosing control can be manual or automatic, based on control signals from a higher-level system.
This device can not only add hydrazine, but with slight modifications, it can also add other oxygen scavengers such as carbazide and dimethyl ketoxime.
