The Location of the APC Decision Trees in the Global Orchard

Here is a sequence of orchard clusters, sub-clusters:

Cluster Industrial Production:

It is logical to identify the clusters by the standard codes. NAICS has been developed by the Dept. of the Census. You can type in a key word and get the code from the following site: http://www.census.gov/epcd/www/naics.html.

The North American Industry Classification System (NAICS) has replaced the U.S. Standard Industrial Classification (SIC) system. NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America.

Most of the McIlvaine data identifies applications using the older SIC code. You can convert to the new code from SIC through the following: http://www.logisticsworld.com/sic.asp

Figure 2 shows the comparison between the NAICS and SIC for power generation.

So using the NAICS as a starting point, here is one example.

We have identified 18 branches and twigs ending with the media used in the dust collector. Each branch is important in the identification. A shaker collector could be used instead of a pulse jet. Bags could be used instead of cartridges. So the selection of the media is determined by these choices.

In terms of suppliers reporting experience and success it is extremely valuable to provide this level of specificity. If the media were used in a bag instead of a cartridge its performance would not be nearly as relevant.

Similar applications will be found in the lime industry. See Figure 3.

Lime processes mainly contains the following basic steps

         Winning of limestone

         Limestone storage and preparation

         Fuels storage and preparation

         Calcination of limestone

         Quicklime processing

         Quicklime hydration and slaking

         Lime storage, handling and transport

McIlvaine has a whole site devoted to lime manufacturing with information on the processes and dust control:  http://www.mcilvainecompany.com/lime/subscriber/default.htm.

So from the global orchard starting point we go to the Industrial cluster and then to 37410 Lime Manufacturing, shown in Figure 4.

So with these two examples we have identified applications for pulse jet filters, for cartridges, and for polyester needle felt. By contrast the kiln dust collector would not use the same media because of the high temperatures. One option for this application is shown in Figure 5.

These examples show first classifications which are already in McIlvaine Decision trees (coal-fired power) and classifications which can be derived from future decision trees (lime).

McIlvaine will be translating the power plant decision tree classifications into Chinese. The specific near term goal is to make the Desox-DeNox conference more valuable with the use of the system.

There is a further opportunity for any company to work with McIlvaine to list all its products by application using the universal decision tree classification system   in both English and Chinese. To pursue this further contact Bob McIlvaine at rmcilvaine@mcilvainecompany.com  (847)784-0012 ext 112.
