Focused Webinars on PacifiCorp NOx Control will be arranged and
recorded in the next two weeks.
As explained below, we are arranging focused webinars to discuss subjects which
can impact the PacifiCorp NOx decision. The recordings will be posted
and available for the general discussions on September 1st and 8th.
We plan to discuss catalytic filter performance, sorbent injection for SO3
removal, air heater, changes, reagents including H2O2,
and in duct SCR.
The August 9th Alert summarized the conclusions at the end of the PacifiCorp
webinar on August 2nd. Since that time, there have been further
discussions and the tentative conclusion that raising the air heater exit
temperature and adding Sorbacal® ahead of the baghouse will result in
an installation to cost effectively remove NOx. The other requirement
is initial NOx reduction in the furnace through optimization and
SNCR. Two more webinars will be held on the project. On September 1, there
will be a discussion of the back end options. On September 8, the front end
options will be discussed. In each case, participants will be advised to view
new information added to Power Plant Air Quality Decisions (PPAQD).
There is the belief that NOx leaving the furnace can be reduced to as
low as 0.l lbs./MMBtu. On the other hand, maybe the exit quantity would be 0.22
lbs./MMBtu. Since .07 lbs./MMBtu is the exhaust limit, the removal efficiency
for the catalytic filter will have to be 30-70 percent. Doosan,
Siemens, Emerson and GE have all made
presentations relative to reducing NOx leaving the boiler to as low
as 0.1 lbs./MMBtu. In order to further determine the likelihood of this
reduction, we have asked for case histories and white papers. We have already
posted additional papers from Emerson and one from GE. Siemens is supplying
several papers. We may make some phone calls to find out the current status of
these installations. We are soliciting names of people and locations so we can
make these calls. Results of the calls will be posted. In some cases, where
confidentiality is desired, we will just provide a generic plant name such as a
“large plant in the Midwest.”
Relative to the back end and urea/ammonia/H2O2 injection,
we need recommendations on where and which chemical should be injected. If both
SNCR and catalytic filters are used, there will be ammonia slip from the
SNCR. Where should the additional reagent be injected? Where should the
Sorbacal be injected? Is there any reason to consider SBS instead of hydrated
lime? Bob Crynack believes the addition of H2O2
along with the urea will increase removal efficiency. This needs to be further
pursued. More information on the projected temperature vs. efficiency on the
catalytic filters will be provided by FLS.
SO3 removal with Sorbacal will solve the bag blinding problem at
PacifiCorp
Gerald Hunt of Lhoist writes “Mitigating concern over blinding the bags should
just be a matter of achieving sufficient SO3 removal which can be
driven by proper injection location (further upstream the better, not to mention
taking advantage of the co-benefits of injecting upstream of air heater) and a
well-designed injection grid system. We have several DSI/SO3
installations demonstrating the effectiveness of Sorbacal SP to provide very
effective SO3 capture which we can back up with references. We
are happy to work with PacifiCorp on providing technical expertise regarding
injection location(s) and injection grid design if they desire.”
McIlvaine is trying to arrange a recorded video interview with Lhoist and post
it later this week. If you are interested in asking questions or making
comments, we can include you as a participant.
Air heater outlet temperature adjustment questions to Arvos and Howden
The application of catalytic filters is linked directly to the air heater outlet
temperature. The specific question is what is the consequence of raising
the air heater outlet temperature from 275oF to 300oF or
higher? What is the role of air heater inlet air leakage? What is the impact of
a temperature increase on fan output and plant efficiency as compared to the 9”
additional pressure drop of an SCR system? The broader issues relative to air
heaters need to be addressed for three potential locations.
(a)
location of the catalytic filter ahead of the air preheater and them revising
the air heater design based on clean hot gas.
(b)
Location after the air heater with a preference for temperatures around 350oF
(c)
Back end SCR where a rotary heat exchanger is used to reheat the gas prior to an
SCR.
We will try to schedule a webinar with these suppliers to review the options.
Interviews with Optimization suppliers to review case histories in the PPAQD
Doosan, Emerson, GE and Siemens have all made presentations in PacifiCorp
Webinar 2. We plan to interview each separately in the next week and review the
case histories which we are posting to PPAQD. Here are three we posted on
Emerson installations.

We will attempt to record video interviews with each of the four presenters in
the next week or so and give participants ample time to view them prior to the
September 8 meeting.
In Duct SCR options
In the last session, we briefly looked at Fuel Tech schematics with in duct SCR.
We will arrange a more in depth discussion.
If you want to participate in any of these more focused webinars, please contact
Bob McIlvaine at
rmcilvaine@mcilvainecompany.com
There may be other options that have been missed in the three previous webinars.
If you believe there are other technologies which should be considered, please

The logical questions are how? And why? Let’s start with “how”.
How:
Your information can be included at no charge in Gas Turbine and
Reciprocating Engine Decisions. This program includes an intelligence
system which is easily accessed. It includes summaries which are carefully
written to provide immediate knowledge and then links to the actual data.
We will write the summaries when you send us case histories, presentations and
articles. In the last week, we have posted 100 summaries and linked to
papers with thousands of pages.
We are offering a free 20-minute video interview to each supplier, consultant,
or association. The quickest and easiest approach is for us to set up the
GoToMeeting and then display your website. We move from page to page as we
discuss your products and why an engine owner would want to know about them.
If there is not sufficient information on your website, you can send us a power
point presentation in advance and we will display that while we discuss your
products.
We will also post comments which would be best structured as “letters to the
editor.” They will have the impact of an organized blog. These comments will be
included in the biweekly updates.
Why:
Why is McIlvaine offering free services? Why will engine operators use it?
Why try to do so much in one month?
Why is McIlvaine offering free services? The answer is found in a popular
book called Wikinomics. The Decision Guide is free to any engine owner or
operator but is $1600/yr. for others.
59D Gas
Turbine and Reciprocating Engine Decisions However, the one
free recording and continuous posting of data is free.
Why will engine operators use it? This question is best answered by
example. It is obvious that a small diesel power plant in India is in need
of this guide. But what about a large coal-fired utility in the U.S.
Why would they use the McIlvaine Decision Guide on coal-fired boiler NOx
control? They can easily afford the best consultants and can have personal
meetings with any supplier when they wish. The answer is that despite all this
expert knowledge on which to draw, the utility finds it will make better
decisions with the guide. If you need to be convinced of this, just
sign up for the free PacifiCorp NOx control webinars 4 & 5 on
September 1 and 8.
Why try to do so much in just one month? The power generation industry has
to become part of the fast moving digital world. If you go to management
who says you have to wait a month while they consider whether to conduct a
simple video interview about your website, you are part of a culture which has
to change. The newest decision makers are accustomed to instant answers to
questions and access to the latest information. In fact, if you supply a case
history from a few years ago, we will post it. But at some point we will want to
call the plant and find out how it is working today. We want to demonstrate that
in just a short period of time we can create a uniquely valuable guide.
But we also want to demonstrate that is just the start and that we will be
adding equivalent value every month.
