Exhaust incinerator processing is a very popular topic, the focus that the dry burning, is the 80% of the water with sludge dryer for drying sludge, after drying, it is a kind of granular, first send it to a dedicated incinerator to burn inside, burned to produce high temperature flue gas to the dryer in the sludge drying, of course, such a direct type dry burning, it is need of auxiliary fuel, this is pure sludge drying, burning to reach thermal equilibrium, the auxiliary fuel cost is higher.Its core equipment is the dryer, the dryer has some special structure, it rotates to smash the sludge, and through the heat exchange with high temperature flue gas, the sludge to dry.
       There is also a special rotary incinerator, and this incinerator, of course, can actually be used to incinerate dried sludge in other incinerators, such as fluidized beds.The drying incineration in the world has some characteristics, such as high efficiency, relatively low investment, small land area and low energy consumption, which have some outstanding advantages.However, some plants have been built and do not have the conditions to install another set of drying equipment in the plant, so it may be necessary to build a sludge drying facility workshop in a relatively distant place, so the indirect drying with steam may be more suitable for long-distance transmission, which is an indirect drying means.
       In addition, there are many cities that have domestic garbage treatment or are planning to have domestic garbage treatment, and some municipal sludge cannot be treated.So we now have a technology which is to mix the waste with the sludge and incinerate it.Its core equipment is a sludge drying machine, another is the tradition of the grate type incinerator, the heat generated in the use of waste incineration flue gas to dry the wet sludge, and then the higher heating value of sludge after drying to the incinerator to burn inside, as long as the blending ratio is not too big, such as blending proportion less than 20% of the whole plant power generation benefit is basically no effect.At the same time, the sludge and disposal, through the sludge dryer and some supporting transport equipment, the sludge and disposal, it should be said is a very good technology, at the same time can also mix a small amount of industrial waste and straw.
       Comparing separate dry incineration with mixed incineration, it should be said that mixed incineration has great economic advantages.
