++++++++++++++++++++++++++++ Inspection informaton below ++++++++++++++++++++++++++++++
E. Keeler Company was purchased by Tampella Ltd. in October 1989, changing the name to Tampella Power Corporation, of Williamsport, PA. Tampella is now owned by Kvaerner, Inc. and Kvaerner Pulping, Inc., of Finnland. It is possible that former E. Keeler Company technology may have been purchased from Tampella/Kvaemer in 1996, changing the name on technology ownership to Faber Burner Company and moving to Lock Haven, PA.
The limited time allowed only a superficial inspection of the boiler. The following observations were made:
I. The boiler has two steam drums that were open to atmosphere on both ends. Light bulbs were not left on inside the drums as is normally done to produce a little heat continuously and prevent condensate. Both had open cardboard containers ofdesiccant, and drum interior surfaces showed no signs of corrosion other than mild surface rusting. The drum walls showed no water marks and no evidence ofscaling or of pitting in the area where the water line would be. Tube interiors were clean and had no discoloration or scaling; tubes looked brand new. Provisions for dry steam were not apparent.
2. The boiler has no mud drums. Each side water wall has a header, and the two headers were closed up. We were unable to open the hand holes without heavy wrenches, which we didn't have. One header had an open drain valve but the other header had a closed drain valve that we got open and nothing came out.
3. Refractory, and pipe and duct insulation was intact and in like-new condition.
4. Several soot blower motorized drives were disassembled and some or all the parts were laying on the floor/grating.
5. The combustion area was not entered. The stoker grate did not appear burned or damaged. The grate total area seems quite small compared to the steam production rating of the boiler.
6. The E. Keeler Company boiler appeared to have no front arch to aid coal drying and ignition whereas the B&W boiler I'm experienced with did have a front arch that reflects heat from the active coal bed downward onto the coal entering from beneath a coal gate, for rapid coal drying and ignition. The Keeler boiler appears to cascade coal from vertical front wall distributor outlets that may allow for drying and ignition (Is this a type of spreader stoker/chain grate combination??). In addition, B& W boilers have a rear arch that will deflect air percolating up from beneath the chain grate, which is relatively rich in oxygen, toward the part of the bed where combustion is more rapid and where unburned volatile matter may still be present. The Keeler boiler did not appear to have a rear arch.
7. Refractory is not discolored except for a few faint stream lines. The boiler apparently wasn't operated very long or very hot.
8. No fans or valves were inspected. No drive systems were inspected, although it was apparent the shafts need to be cleaned of surface rust, and seals checked.
9. The bag house was not opened.
10. No check was made for mercury in switches (I saw one), lead in paint, or asbestos in refractory and insulation.
11. The ash pit was not entered. It contained ashes which blocked the view of ash pit walls. A faint ash line was visible on the refractory lining.
12. The ash pneumatic conveyor was not checked.
13. Steps, platforms and hand rails are of excellent design and in very good condition.
