Brand: Erun environmental protection
Name: Laboratory desktop thermal power plant steam boiler water quality tester
Model number: ERUN-ST7-7
Parameters: Sodium, conductivity, silica, iron, copper
According to the flow mode of water in the evaporation heating surface, it is divided into natural circulation boiler, forced circulation boiler and direct current boiler; both natural circulation boiler and forced circulation boiler have steam drum, referred to as drum boiler, while the water in the direct current boiler does not circulate, and the preheated water directly enters the riser tube for heating and evaporation. Therefore, the requirements for boiler water testing in the furnace are very high. Laboratory desktop thermal power plant steam boiler water quality tester ERUN-ST7-7 boiler feed water quality produced by Erun Environmental Protection:
Drum boiler：conductivity、dissolved oxygen、hardness、iron、copper、chlorine ions、silicon dioxide、TOC
DC furnace：conductivity、dissolved oxygen、sodium、iron、copper、chlorine ions、silicon dioxide、TOC
