BIBLER LUMBER GOES GREEN WITH GREEN BURNER
BIBLER LUMBER GOES GREEN WITH GREEN BURNER
How the Green Burner works
Although direct-fired kilns are generally costeffective because they use wood residue as fuel , the lumber is often discolored and devalued because of the ash and soot they produce . The presence of soot and ash also creates danger of explosion or fire . And while steam-heated kilns are known to produce cleaner wood , they have significantly higher operating costs in addition to the substantial cost of replacement parts .
Proprietary technology in USNR ’ s Green Burner offers complete combustion ; lumber stays clean and free from ash . A bonus for Bibler Lumber , fuel savings are in the range of $ 200,000 per month .
USNR ’ s Sloped Grate Green Sawdust Burner They had also worked with USNR in the past on other eliminates many costly burner problems while kiln and burner projects and were well satisfied with increasing the value of your lumber . The USNR unit the results . burns sawdust like other direct-fired kilns , but it also The burner housing is constructed of 9 ” fire brick employs an afterburner module to ensure complete and IFB ( insulating fire brick ) that will withstand combustion , which keeps your lumber remarkably temperatures of up to 2600 ° F , then covered with 3 ” clean and free from ash . This is just the kind of unit fireproof insulation board , and finally covered with that Terry Freeman , president of Bibler Brothers steel sheeting . The afterburner duct sections , along Lumber Company , was looking for when he set out with the choke and tee sections are also 9 ” fire brick , to improve the efficiency of the mill ’ s existing two which is covered with a painted steel shell . ( See gas-fired dry kilns . section at right for details of the proprietary technology Bibler Lumber is located in Russellville , Arkansas . that ensures lumber stays clean and free from ash .)
It is co-owned by Terry Freeman and James and Terry was very pleased with the outcome of the
Laurie Bibler . Like most good businessmen Terry project . He says , “ With the continuous kiln we are hates to waste anything , and that was his motivation seeing better throughput , better grade recovery , and when he set out to update his lumber drying process . a better overall average moisture content ( lower Terry and Kevin Freeman , VP and General Manager , standard deviation ).” With reported fuel savings in the wanted to find the best solution that would save range of $ 200,000 per month , Terry Freeman ’ s efforts fuel costs , as well as improve the consistency and to improve the efficiency and throughput of his lumber quality of the dried lumber . They looked at what other drying process have made his operation both leaner processors were doing with their kilns , and decided and greener . on an upgrade to extend the length of the kilns and , in conjunction , to convert the kilns to utilize wood waste as an efficient , low-cost heat source .
Besides the kiln conversion , Terry and Kevin installed USNR Sloped Grate Green Burners . They selected the USNR Green Burner for its performance record , and based on good reviews from other users .
Unique Turbo Technology™ produces cleanest , high-value lumber
The cyclonic afterburner , located just after the main burner chamber , is a feature that sets USNR ’ s Green Burner apart from ordinary burner systems . Proprietary Turbo Technology™ enables temperatures in the afterburner to get much higher than temperatures in the main burner where sawdust is initially fed . Heated air from the burner at 2000 ° F is blended with 200 ° F return air from the kiln in the USNR insulated blend box , and put back into the kiln at 500 ° F . An added safety feature unique to the Green Burner , the blend box incorporates an isolation flapper , and in upset conditions hot air is released out of the stack instead of cycling to the kiln . In effect , the kiln can be isolated from the burner . No other direct-fired kiln on the market is capable of attaining such a wide range of temperatures .
This afterburner provides complete combustion , keeping high value lumber in the kiln remarkably clean and free from ash . In fact , the resulting dry lumber has proven to be as clean as that produced by any steam kiln .
