Residence time in furnace

The residence time of garbage incineration has two concepts:


1. It refers to the residence time of garbage in the grate from the time it enters the furnace to the time it is discharged from the furnace. According to the current situation of garbage composition, calorific value and moisture content, the residence time of garbage in the furnace is generally 1 ~ 1.5h.


2. Refers to the time it takes for the toxic and harmful smoke generated by garbage incineration to be further oxidized and burned in the incineration condition in the furnace, so as to turn the harmful substances into harmless substances.


The residence time is an important basis to determine the size of furnace body.

Generally speaking, in area above 850 ℃ temperature for 2 s, can meet the needs of the waste incineration technology.


The advantage of a grate furnace is that it does not require pretreatment of waste.

The technology is mature and widely used in foreign countries. Its disadvantages are as follows:


1. Furnace row must be heat-resistant, during long-term continuous operation, the thermal stress must remain unchanged, so that the furnace row material requirements, and the processing of the furnace row is complex, because the furnace row needs to rotate, low reliability and high energy consumption constitute its problems.

2. Because of the complex composition of garbage, it is difficult to keep the common grate moving uniformly in the whole grate and to burn uniformly and completely.

3. It is difficult for the grate to adapt to refuse incineration with a wide range of moisture content, because the waste with high moisture content needs a wide dry area, which makes it difficult for the waste with high water content to be completely burned.

4. More difficult to control furnace temperature, waste slag at above 1000 ℃, and 1050-1100 ℃ in the softening and viscous state, become the special corrosive substance, may be corrosion of furnace wall, at the same time under high temperature condition Nox concentration increased.

5. It is difficult to realize large-scale furnace and remove HCI gas in the furnace. Special equipment and HCI removal equipment need to be installed in the tail, which increases the investment cost.

6. It is necessary to set up special sewage treatment facilities for refractory landfill leachate.

7.The grate furnace is not only complex to manufacture, high cost, but also large in size and covers a large area.
