Fly, deposit and link pipeline below grey chamber, you can thoroughly discharge ashes.
The grey chamber of depositing is funnel-form, up big and down small.It is funnelform to deposit grey chamber ashes be gathered to least significant end, just
In ash discharge.
The utility model compared with prior art, has the following advantages：
1st, the gas after heating enters combusting rice hull heat exchanger, and gas flow rate constantly reduces so that ashes are deposited in as far as possible
The bottom of heat exchanger, reduces the dust burdening of gas, improves heat exchange efficiency.
2nd, gas flow rate is constantly reduced in interior intracavitary, extends the heat exchanger time of gas and heat exchanger, improves heat exchange
Efficiency.
3rd, combusting rice hull heat exchanger is assembled by tiles heat exchanging body, after one of tiles heat exchanging body damage, as long as more
The tiles heat exchanging body is changed, reduces maintenance cost.
4th, tiles heat exchanging body from top to bottom includes upper water chamber, heat exchanger tube and lower water chamber, liquid have the water inlet of lower water chamber into
Enter and constantly gush upwards, ensure that in watt heat exchanger tube and fill liquid all the time, avoid heat exchanger tube dry combustion method, improve combusting rice hull and change
The service life and heat exchange efficiency of hot device.
