Jamil Bundalli., Kamengo:
"Storage and conveyance of solid fuels"
Discussion/Q&A: For every material there needs to be specific circumstances for the material to bridge. This needs to be taken into account when design/building bins/feeders for fibrous/cohesive materials.
1) How many screws do you need in a feeder? That depends on how much feed needs to be moved across how many openings. Bins can be made taller as they promote gravity flow vs. screw driven bins. Gravity bins work better and positive tapered bins work well with hog fuel. A 100 foot tall bin would be approximate 60 feet in diameter. You need to determine which set-up would be better for your plant, individual meter bins vs. 1 large bin.
Presentation #2
Alex Slauson, Flex-Seal (Bay Valve):
"Mechanical Seal 101/US Patented Two Piece Split Cartridge Seal”
Discussion/Q&A: Dimensions need to be taken to ensure valve will fit. Water temperature makes a difference as to what product you would want to use. Both full and split seal valves can turn 5 rpm to 5,000 rpm. 1) How does the valve seal against the pump casing? The gasket seals against the casing when the valve is tightened. 2) How large of a diameter do the valves come in? Up to 9 to 9.5 inches OD down to 1 inch OD.
Presentation #3
Wade Day, STI CEMS:
“The new opacity Procedure 3 QA/QC requirements”
Discussion/Q&A: If you only use the Zero Gig for your alignment, your numbers will be off. You really have to do an off-stack zero alignment, so your numbers will be accurate. 1) How often do the filters need to be certified? Filters need to be certified once a year. If you have less than .5 drift for 2 years then you don’t have to recertify the filters for another 2 years.
Presentation #4
Kevin Tangen, PE, Evergreen Engineering:
“Wood yard improvements for boiler performance”
Discussion/Q&A: By screening out small pieces of combustible material which would normally float up the stack, you actually have a better burn rate. One of their plants did install fine screens which improved their burn rate. Speaker had not yet received data from this plant identifying the cost of savings at time of this presentation. Dirt, sand, little bits of rock, and other fine incombustible material turns into PM. Screening out ¼ inch material also improves fuel supply.
Presentation #5
Bob Beck, Dresser-Rand:
Discussion/Q&A: 1) Are there hybrid machines (impulse and reaction combined)? Yes. Physical features of each are combined in 1 design.

Presentation #6
Norris Johnston, Solenis:
“Boiler chemistry monitoring and control”
Discussion/Q&A: 1) Are there systems that take action without the operator initiating that action? Yes, there are feed systems that monitor the flow and alter chemistry without the operator initiating action.
2) What clean up options are there to clean-up the returning condensate? Three good ways to filter out contaminants are magnetic filters, resin polishing and chemical treatment.
Presentation #7
Tom Miles, KARR Group of Companies, LLC:
“BioChar Products and Applications”
Discussion/Q&A:1) Thought about mining a landfill? That could be done but there would be a lot of dirt in it which could be sourced for landscaping/remediation. 2) Regarding log yard waste, is this a skid mounted unit? Yes. It has a small footprint so it could be placed next to a boiler. Fuel mixture could be anything as long as the fuel is of uniform size.
Presentation #8
John Zora, Nalco:
“2015 Top Ten for Boiler Water”
No questions/answers on this one. He just showed slides of what were his Top Ten and explained why they made the list. Quite a humorous speaker, the whole room was laughing.
Presentation #9
Luke Buoy, Hudson Bay Insulation:
“Insulation Lifespan and installed material effectiveness.”
Discussion/Q&A: 1) How long is the payback on installation of insulation? On a 300 – 350 degree line the payback is one year.
Presentation #10
Frank DeSilva, Loprest Water Treatment Company/Resin Tech:
“Practical Considerations in the Storage, Loading and Use of Ion Exchange Resins”
Discussion/Q&A: 1) Is there a convenient test to measure the resin moisture content on site? Yes. If you can crush the beads between your fingers, then the resin is oxidized. You could also put some in the microwave and weigh it before and after. Speaker said when he first was told of this, he was not told how to use the measurements from using the microwave

Presentation #11
Bob Morrow, Detroit Stoker Co.:
Presentation #12
Robert Wilson, Emission Technologies, Inc.:
“Reduce continuous emission monitoring (CEMS) costs while increasing reliability with modern optical benches and software.”
Presentation #13
Karen Sercey, Clyde Bergeman Power Group :
Discussion/Q&A:1) What kinds of methods are there to clean ESPs? We recommend gritblasting or you could hydroblast. Ms. Sercey was not the original scheduled speaker. A member asked what style of wrapper should be installed on the plate. She said she did not know but that when she got back to the office she would find out for him and let him know the answer.
Presentation #14
Steve Kenny, Columbia Water Technology LLC:
“Reverse Osmosis Troubleshooting”
Discussion/Q&A: Only one question was asked but when the speaker asked for clarification on what piece of equipment the member was talking about, he didn’t know what the member was referring to. Speaker said that he would get with him after the presentation or if necessary, go to his plant.
