Description
Technical field
The utility model belongs to thermal power and field of environment protection, and in particular to a kind of industrial refuse is mixed with house refuse
The boiler of combination burning.
Background technology
With industrial development, industrial waste quantity increasingly increases, and industrial refuse species is various, complicated component, leads to
Frequently with Rotation error processing, but Rotation error also has some distinct disadvantages：Garbage treatment quantity is small, and flying dust amount is big,
Lime-ash burns not thorough, and burning is whard to control.For house refuse, component of refuse fluctuation is larger, by region, season, day
The factors such as gas influence, and calorific value change is general to be handled using grate type incinerator than larger, the type of furnace technology maturation, stable,
Reliably, treating capacity is big, and can produce steam is used for steam supply, generates electricity, but the application of grate furnace also has limitation, is not appropriate for calorific value
Higher industrial refuse and some be difficult to the material that burns.
Further, since it is traditional slag tap between limited by space, engineering truck can not normally come in and go out, can only be at a two ends of slagging tap
Reversing enters.Meanwhile, during slag hangs maintenance, there is potential safety hazard in a narrow space of slagging tap, and have a strong impact on work effect
Rate.
Therefore, in the urgent need to developing a kind of brand-new industrial refuse and the burning boiler of house refuse can be handled simultaneously.
Meanwhile, also to solve to slag tap narrow space the problem of.
