Welcome to www.dcmlogic.com! Let's view the demo...
Here's a view of a boiler room with 1 P4. Note the stack temperature and the boiler supply temperature.
This boiler room has 3 FHG's in it. They're all heating now. Why is the buffer tank so cold?
We'll look more carefully at this installation with 2 P4's. Note the buffer tank temperatures and the percentage it is charged.
We'll see why one has just gone into shutdown. It's not ideal––the buffer tank isn't charged!
We can view the temperatures in Fahrenheit or Celsius.
Let's go to the summary page. From here, we can view our entire fleet of boilers in one glance (just those in the demo).
We can quickly see if there are any problems or unusual behavior that might need attention.
If any boiler has a fault, it is highlighted in red.
This shows a summary of boiler operation: temperatures, key boiler variables for both boilers, and the states of both boilers.
We immediately see something unusual. Look at the spikes in Blr 1 supply temp.
The spike causes the boiler to shut off, which is shown in the 2nd and 3rd graphs from the top.
You see the abrupt change in boiler variables and you see the abrupt change in state.
Let's look at a smaller time window--the last 2 hours.
Now, let's zero in on 14:30 UTC for a closer look. Choose the "Fixed" time window and adjust the endpoints.
You can see we've now centered this temperature spike in our window for a better look.
Let's expand the window to see a large portion of the day.
We can look at this same time frame on an earlier day...
Something funny is happening after midnight UTC––better go back and take a look sometime.
We can look at a particular cycle of either boiler. Here, we're looking at the 2nd most recent cycle of Boiler 1.
It started its Preparation phase at 12:11 and completed a shutdown cycle at 14:52.
Now, we'll look at the most recent cycle of Boiler 1: 14:52 → 16:13. Not very long due to the temperature spikes...
Let's look at some other graphs.
This shows the air intake temperature and the flue gas temperatures.
This shows how the levels of pellets in the daybins change over time.
What if we want to see something else? These graphs are customizable!
Let's add another plot onto the lower graph.
Just for illustration, we'll add the supply temperature for Boiler 1.
There's the new plot on our lower graph.
Let's get rid of the lower graph altogether so we can focus on the plots of the Boiler States.
A few more graphs to look at...
You can see that the grate is opening and closing several times to let the ash drop down in Boiler 2 around 13:25.
Did you see the graph update as new data became available?
This shows the inputs for the two boilers. The most obvious behavior is the activity of the stoker drive in the bottom graph.
Note that the drive is active during boiler operation (Boiler State = 3) and pauses when the boiler is not firing (see the sections in the graph above where Boiler State > 3).
The Performance Summary gives quick insight into how the boiler plant is operating. Each column shows stats for the different boilers.
Ideally, the service hours and heating hours should be about the same for the two boilers. They're not, since Boiler 1 is short cycling...
We display the ratio of the (Number of Heating Hours)/ (Number of Starts). Ideally, this would be longer (and similar for both boilers). What's going on?
The BoilerScope captures a comprehensive view of the boiler activity. Let's start with the States.
We can choose to display only those variables that have changed within the most recent hour, day, week or full history.
Sometimes it's convenient to see only the most recently changed items.
Now, we'll take a glance at the variables for the two boilers. Variables are generally measurements or numbers that change over time.
A huge number of variables have changed within the last 24 hours. We can see that the most recent Boiler Supply temperatures were changed at 16:14 and 16:08, respectively.
Let's look at the variables changed within the last hour only.
A quick look at the Inputs.
And the outputs... Let's look at a full day's period.
Finally, let's check out the parameters. Parameters are settings-- they don't change over time. They're adjusted at the boiler with the entry buttons.
Since they don't change over time, we don't see any listed when we look at the 24-hour time window.
We track a lot of parameters! What to look at? We make it easy by highlighting in green any differences in settings between the two boilers.
Then, it's up to you to determine if the mismatched settings are intentional or perhaps need to be adjusted.
You can view almost 1000 parameters per boiler!
You may want to look at the variables and parameters the way they are organized on the boiler screen.
That's the purpose of these rightmost menus. Let's look at a couple, starting with the Boiler Temperature.
Flue Gas...
Lambda Values...
And under Fröling Data 2, Cascade System...
Pellet Times and Service...
One last look at the boiler fleet on the Summary Page.
