Now let us go into the details of drying .
We refer to the data gathered during the running of BSR500 in our furnace which channel hot flue gas to drum dryer to dry sawdust .
Below you can find a table which shows our furnace burning wood offcut , wood pellet with Pellet Burner Model BSR500 and compared it with diesel . ( based on calculation )
The table shows that Wood Pellet with the correct Pellet Burner are capable of competing with even the lowest cost fuel . The reasons are as follows :
1 ) Burning wood are OLD TRADITIONAL METHOD of producing heat , so the efficiency are very low , we gather that if the wood offcut calorific value is 2,500 KCal / kg , the efficiency is only 36% as compared to 80% for wood pellet with the Correct Pellet Burner .
2 ) Wood Offcut have fluctuating calorific value , the feeding would not be consistent , the air fuel ratio will be different , so the worker tend to blow air full blast thus lowering the temperature in the furnace in the end causing higher consumption of wood to maintain high temperature .
3 ) Pellet Burner work exactly like Diesel Burner , it fires when temperature drop to lower set value and stop firing when it reach the upper set value . This will ensure no wastage of over firing or under firing .
4 ) If you have seen worker work at furnace then you will know what I mean with this statement .
" FEED THE FURNACE FULL AND SIT AS LONG AS POSSIBLE " .
HOW CAN YOU GET EFFICIENCY WHEN THE FURNACE IS FULL BUT NOT BURNING , worst still plenty of smoke will come out from the chimney waiting for DOE to write you a summon . This will also cause temperature to drop until your production are lowered and this cause money too . That is why some company keep using Diesel Burner even though biomass are much cheaper because loss from production are much more higher than savings .
As to the comparing with Diesel you can see the savings come up to 75% . This is a lot of money if you are burning RM100,000 of Diesel per month .
If you are in this Situation , please consider a Wood Pellet Burner :
1 ) Burning Diesel / Gas
2 ) Material Dried not dry enough or not up to specification
3 ) Dryer output too low
4 ) Furnace too small
5 ) Factory space too small for big biomass boiler
6 ) Want to increase capacity of furnace
7 ) Heating / Drying are not consistent
8 ) Shortage of workers
9) If you love mankind , do your part in reducing CO2 increase
HAPPY NEW YEAR
