WNS series horizontal internal combustion boiler is
designed based on the imported German Technology and domestic
sophisticated technlogy,and is three-pass and wetback structure
wall ,which is the first pass ;
The high temperature smoke after burning gathers in the reversal
chamber ,then turns to the second pass,the corrugated tubes;after
convective heat transfer ,the smoke temperature gradually falls
down;then it enters into the front smoke box ,turning to the third
pass ,namely light pipe bundle ;after that ,it passes by the back
smoke box,then the chimney and finally is discharged into the air .
Features :
1. Large capacity
Adequate steam stock space and heating area makes it possible for
boiler to generate steam of high thermal efficiency and high
quality.
2. Smoke box
The smok box door employ the Gnerman Tchnology ,which is the hinged
door structure ,with good insulation ,easy for opening
,maintenance,cleaning,checking.
3. corrugated furnace
this series boiler employs fully corrugated furnace
enhancing the smoke stirring,and effectively imporving the heat
transfer of per unit area and per unit volume.
it also strengthens the strength and elasticity of the
furnace,effectively protecing the pressure part from damaging due
to the increase of the stress in thermal expansion process of the
boiler.
4. Installtion of condenser at the end of the flue pipes
The added condenser absorbs the waste heat from the discharged
smoke,increasing the inlet water temperature of the boiler,reducing
the temperature of the discharged smoke,raising the thermal
efficiency up to 98%,thus greatly saving the cost.
The condenser used finned tubes,enhancing the heat area and heat
transfer efficiency and reducing the occupation space.
The finned tubes are made of ND steel or stainless
steel,effectively avoiding low temperature corrosion of the steel.
5. Automatc control
Totally automatic operatin:automatic adjustment of burning,water
level,temperature and steam pressure ,automatic protection.
6. corrugated flue pipe
It is of sophisticated manufacturing technology ,with fully
automatic pipeline pressure operation
Enhancing the heat transfer and boiler thermal efficiency.
Corrugated flue pipes are the heat transfer element of high
efficiency which are development after many years' research of our
company.Upon the selection of corrugated groove depth and pitch,the
heat transfer coefficient is about 1.2times that of common flue
pipes at the mininum of flow resistance.
