The main factors affecting the quality of the lime burning: fuel and heating mode. Solid fuel than gas, liquid fuel heating effect supply sewage treatment with lime, fuel to low S, P content of the fuel. Heating mode is arranged for hot spots in the middle of bank forced pressurized heating Buy sewage treatment with lime, or high-temperature air layer is heated through sewage treatment with lime how much a ton better. Quicklime and hydrated lime difference: lime slurry formed after curing quicklime, calcium hydroxide lime particles form colloidal structures sewage treatment with lime, fine particles (particle size of about 1μm), a large specific surface area (up to 10 ~ 30 m2 / g ), its thick layer of adsorbed water film, can absorb a lot of water, and thus have a stronger ability to retain moisture, ie good water retention.
