If the boiler uses fresh water, a small blowdown of the boiler can easily result in excessive salt content. Because: The water softening process is a process of exchanging calcium and magnesium ions from raw water with sodium ions from salt through resin, sulfonated carbon and other media. The solubility of calcium and magnesium ions in water is very low, and it is easy to precipitate in the boiler and form scale in the drum, which affects the efficiency and safety of the boiler. However, the solubility of sodium ions (i.e. the solubility of sodium ions). the salt you mentioned) in the water is very important and can be released through the sewage drain.

The whole process of the thermal system is a complete water vapor recycling process. A waste heat boileris installed at the furnace end and furnace head of the production line to exchange heat with the exhaust gas. After heat exchange, the superheated steam generated by the boiler is fed into the steam turbine to do so. work, and the steam turbine drives the generator to produce electrical energy. The steam after work is condensed into condensate through the condenser. It is combined with the effluent from the flash evaporator via the condensate water pump. It is pressurized by the boiler feed water pump and enters the AQC boiler economizer to heat the water to high temperature. heated by the economizer passes through three channels sent respectively to the AQC furnace drum, the PH furnace drum and the flash evaporator. High temperature water entering the steam drums of both boilers circulates and is heated in the boiler, ultimately generating superheated steam.ffée. The two superheated steams are collected and then enter the steam turbine. High temperature water entering the flash evaporator generates saturated steam of a certain pressure based on the principle of flash vaporization (high temperature and high pressure water will partially vaporize instantly after entering the space low pressure) and enters the rear stage of the steam turbine to assist in the production of electricity. The steam after carrying out the work is condensed through the condenser and forms condensation water to again participate in the circulation of the system. The water consumed during the circulation process is reinjected into the system by the pure water produced by the pure water device.
The residual thermal energy production from sintering is heated using the gases from combustion of the tail drop bellows of the sintering machine and the closed section of the ring cooler ofsintering. Waste heat boilers are used to recover low-quality waste heat energy, and combined with low-temperature waste heat generation technology, the waste heat generated by waste heat boilers is used.
