COKE, ANTHRACITE 

The  optimal  fuel  is  coke  with  granularity  of  40  –  60  mm  but  it  is  possible  to  burn  even  coke and anthracite 
with granularity of 20 – 40 mm (nut 2). In case of sufficient chimney draught (0,15 to 0,25 mbar) it is possible 
to burn even non – caking anthracite with granularity of 30 – 50 mm (nut 1) and 50 – 80 mm (cobbles). 
 
WOOD  

To reach the rated power of the boiler it is necessary to keep a maximum humidity at wood of 20 %. 
Cleaning of the grate is performed so as the hot fuel would not get through to the ashtray. 
The fuel needs to be stored in dry conditions.

Other sorts of wood such as wood clips, wood shavings, sawdust, granules or coal – cakes can be used as 
additional  fuel.  In  case  of  heating  with  smaller  clogs  (wood  clips,  wood  shavings,  sawdust,  granules)  it  is 
necessary to put logs in the bottom part of the burning chamber so as the fuel would not get through to the 
ashtray. It is possible to reach smoother burning by further interlaying of the fuel. 
These sorts of fuel must have heating power in the range of 12 to 15 MJ.kg

-1

 and humidity to 20 % to prevent 

from reducing of the mentioned boiler power. 

 

Heating up  

 

1.  Check the water volume in the heat system on the thermomanometer. 
2.  Open the closing armatures between the boiler and the heat system. 
3.  Clean out the grate, ashtray, smoky channels and boiler walls. 
4.  Spread  out  the  kindling  through  the  ash  door  with  the  stoker  –  hole  on  a  cleaned  grate  along  its  entire 

depth.  

5.  Set the smoky flap in the chimney – pot to position – open and close the stoker door. 
6.  Set the kindling afire through open ash door and stoker door. 
7.  Close the stoker hole and ash door and fully open the stifling 
8.  Thinner layout of the basic fuel to be put up on the burning wood. 
9.  After  its  good  burning  up  more  fuel  to  be  put  up  to  the  bottom  part  of  the  stoker  hole,  the  fuel  to  be 

stacked to a uniform layout along its entire boiler depth.  

10.  As soon as the fuel grades to a dark red flame the air rose of the secondary air input on the stoker hole to 

be opened with an instrument. 

11.  After flames become yellow the air rose of the secondary air input to be closed.

1.  After reaching the heat water temperature the burning air input to be adjusted. The boiler power in rough 

limits is regulated with a chimney draught change with a help of the smoky flap in the chimney – pot. The 
fine  power  control  is  performed  by  means  of  a  choker  (stifling)  by  manual  regulation  of  the  air  intake 
under the grate. The choker (stifling) in the ashpan door must be almost closed the at the moment when 
it is reached the required temperature of heating water.  

2.  According  to  heat  needs  and  burning  intensity  the  boiler  is  needed  to  be  supplied  with  fuel  during  the 

operation. Feeding the fire so as the fuel layout was equally high along the entire boiler depth. 

3.  When using the anthracite it is necessary the air rose of the secondary air input in the stoker hole to be 

partly opened for the whole time of the build – up of gases and flames out of freshly fed fuel (the air rose 
of  the  secondary  air  input  with  regard  to  the  surface  temperature  is  necessary  to  be  controlled  with  an 
instrument. 

4.  At change over to night still operation the grate to be cleaned out, the freshly fuel to be let well burnt up 

and then the boiler power to be suppressed by throttling of the chimney draught with chimney flap in the 
chimney – pot and by turning down the air rose of the secondary air input. The smoky flap and air rose 
opening  level  is  necessary  to  be  tried  out,  it  is  always  necessary  to  make  sure  that  the  product  of 
consumption did not get away to the boiler room. 

5.  The  morning  boiler  operation  reconditioning  to  be  performed by opening of the smoky flap and air rose 

and with grate raking after opening the ash door. 

6.  The ash door must be during the operation permanently closed. 
7.  The ashtray to be emptied according to needs (gloves need to be used).
