Recommended catalytic combustor temperatures.






Combustor temperatures can become extremely hot during operation.

Temperatures above 1800 degrees F. will damage the catalyst.

Temperatures between 1400 to 1600 degrees F. are normal, but temperatures between 1200 degrees F to 1400 degrees F. are recommended.

Very important message.


Understanding the catalytic combustor is as important as understanding how to operate the stove.
In other words, if the stove is operated correctly, than the catalytic combustor will operate correctly as well.



 
 
 
Every catalytic stove purchased by the consumer comes with an operating manual explaining how to operate the appliance. 
It is very important that the consumer read this information before building the first fire in their new appliance.

Every FIRECAT replacement catalytic combustor sold to the consumer by Applied Ceramics includes a brochure explaining everything they should know about the combustor.

Applied Ceramics has a website with combustor information to help the consumer with any questions. 
 
Applied Ceramics also has a courteous staff of service personnel to help consumers with any catalytic combustor questions.

How to get better catalytic combustor efficiency.


Never burn foreign matter in your stove, such as…
garbage, painted wood, large amounts of colored paper, cardboard, rubber, plastic, paneling with glue, oily products and so on.

Burning these materials will gradually reduce the efficiency of the catalyst.


“Burn only seasoned dried wood”




All catalytic combustors used in EPA certified Phase II stoves have a life expectancy of at least, 10,000 burning hours, when used according to the stove's operating manual.

It could be said, that a catalytic combustor’s life is really based on a number of things....


Operating the stove properly,
(Not burning with firebox door open or perhaps closing the by-pass to soon.)

Proper maintenance habits to both stove and combustor,
(Simple things like checking the firebox door gasket.)

Burning proper fuel in the appliance,
(This means burning seasoned dried wood only- no foreign matter that could poison the combustor.)

Using a Certified Phase II stove for home heating and not an older stove design.
Most stoves built today are designed well and protect the combustor from the firebox flames, the older pre-phase I stoves didn't.

Can a catalytic wood burning appliance save me money?




The answer is "Yes".....Let's say for example, if you have a typical unregulated stove and use three cords of wood (at $100/cord) and save on two chimney cleanings (at $50 each) per season, you can save about $200 per season by purchasing a new EPA-certified Phase II catalytic stove. A new catalytic stove will save an additional cord of wood out of every three cords you burn each season.

Your actual savings will vary according to how often you use your stove and other factors.

Nationwide, the net savings from reduced firewood consumption and fewer chimney cleanings is estimated to be $30 million annually. In addition, the health and welfare benefits resulting from fewer smoke-related illnesses and from reduced materials damage is estimated at about $1.5 billion annually.

Four reasons for buying a catalytic wood burning appliance. #4

Reason #4

Catalytic stoves burn very cleanly and efficiently at low to medium heat outputs as stated before. The thermal stress of burning particulates and volatiles, is concentrated in the catalyst, which is a durable ceramic material built to withstand normal temperatures up to 1,700 degrees.  Focusing all of the high temperatures activity in the catalytic combustor allows other stove components to stay in comfortable operating temperatures and not get over heated.

The catalyst should be replaced every 12 to 14,000 hours.  Let's say you burn your stove from November through April (5 months X 30 days X 24 hours/day  4 years = 14,000 hours).  If you use your stove less than 5 months a year or as intermittent or back-up heat, the replacement cycle would be proportionately longer.

The ACI FIRECAT catalytic combustor is backed with a 6 year pro-rated warranty. Read about it in my next posting.

Four reasons for buying a catalytic wood burning appliance. #3

Reason Number 3...

Catalytic wood burning stoves are clean burning.




Current EPA regulations restrict only particulate emissions. Catalytic combustors provide dramatic reductions in airborne particulates, but catalysts are also highly efficient at burning other compounds in the exhaust stream, such as carbon monoxide, methane, benzene, and volatile compounds. This thorough combustion means higher efficiency, lower emissions, and safer performance (because the exhaust is mainly CO2 and water vapor).

Reason #4 in my next posting.

Four reasons for buying a catalytic wood burning appliance. #2

Second reason is catalytic stoves are economical.

Catalytic stoves generally have longer burn cycles, lower stack temperatures and higher heat transfer rates than non catalytic stoves, and so the heat generated stays in your home rather than going up the chimney.

What this means is, the longer burn times and high efficiency and heat transfer rates of catalytic stoves will allow you to heat your home with less wood to burn. 


You save money without sacrificing heat.  It's that simple.

Reason number 3 in my next post.

Four reasons for buying a catalytic wood burning appliance. #1

First reason, catalytic stoves are easier to operate than non-catalytic stoves.



A catalytic combustor begins to burn volatile materials in the exhaust stream at 500 degrees F.  Non-catalytic stoves do not begin to perform efficiently until secondary air is introduced to exhaust temperatures that are over 1000 degrees F.

This is a crucial difference for two reasons...
a. The hotter you have to get your fire before you can start operating efficiently, the more heat you send up the chimney.
b. Achieving temperatures of 1000 degrees in the firebox is not easy task for every homeowner.

Getting secondary light-off in a non-catalytic can be difficult for an experienced technician in a test lab, and is much more difficult for a homeowner using cordwood of varying moisture content and density. 

To achieve the advertised efficiency in a catalytic stove, all you have to do is close the catalytic by-pass damper when the exhaust stream approaches 500 degrees F.  This usually takes 30-35 minutes after kindling a fire, or 15-20 minutes after reloading.

The second reason will be in my next post.

Installing a new EPA approved catalytic wood burning appliance...








Improper installation of your woodstove can result in a house fire or cause greater pollution.
If a stove isn't installed properly, it can also affect the draft of the stove. Proper draft is very important in reducing pollution and maintaining high efficiency. Before having your stove installed, be sure to check with local authorities regarding building codes and permits, and notify your fire insurance company.

Below are a few tips that address the importance of proper installation:

1. By using a certified installer, they can determine the proper draft of your stove, make sure all the seals are tight, and ensure that your stove is installed with all safety measures necessary.

2. They will be able to make sure proper flue size and installation is being used.

3. They will make sure that the draft system seals are as tight as possible to prevent smoke from leaking into your house and to contribute to good draft.

Contact your local certified wood stove installer for complete details.

Again, this is very important for your safety and comfort.

Effective way of operating a catalytic appliance....

The most effective way of operating a catalytic appliance is by utilizing temperature monitors. 
Ideally, two sensing positions will give all the information needed to tell when to engage the combustor, how well the combustor is operating, when it's time to refuel and when the combustor is no longer operational.



The upstream temperature gauge will monitor combustor inlet conditions.
The second temperature gauge should be mounted on the combustor's exhaust side, about a 1/4" off the surface and centered on the unit. This will monitor the catalytic combustion process. If only one temperature sensor is used, it should be the one that reads the exhaust temperature of the catalytic 
combustor.
