5th of 5 reasons why consumers prefer a catalytic stove.

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 12-14,000 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.

4th of 5 reasons why consumers prefer a catalytic stove.

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).

3rd of 5 reasons why consumers prefer a catalytic stove.

Third 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.

2nd of 5 reasons why consumers prefer a catalytic stove.

Second 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 third reason will be in my next post.

1st of 5 reasons consumers prefer a catalytic stove.

There will be more good reasons coming in my next 4 blog posts.

This is the first of the five reasons why consumers would buy a catalytic wood burning appliance. 

First, catalytic stoves are at least nine percentage points more efficient than non-catalytic stoves. The EPA assigns a 72% efficiency rating to catalytic stoves, and a 63% efficiency rating to non-catalytic stoves.  The efficiency labels are on the stoves.

Here's why catalytic wood burning appliances are more efficient...
a. They convert more of the exiting gasses to heat.
b. They work more efficiently at low heat outputs.

Understanding the catalytic combustor and how it works in your stove.

Normally, smoke will burn, at a temperature of 1000 F. or higher. Burning a stove this hot would require continuous intense fire and would require a higher wood consumption.

The answer to eliminate this is the catalytic combustor.

Wood smoke gases coming in contact with the catalyst, causes chemical changes to take place. This will then allow the smoke to ignite at temperatures around 500 F. or (260 C.)

This temperature is easily achieved in the firebox of a wood burning stove.

As the wood gases ignite and burn within the catalytic combustor, clean by-products of water vapor (H2O) and carbon dioxide (CO2) are emitted.

What causes back puffing in my catalytic wood burning stove?

When the combustor has an exhaust temperature over 1400° F. (760° C.) it can act like a glow plug (spontaneous combustion igniter).
Usually the wood gas-to air mixture is either too lean or rich to form a highly flammable mixture. There are times when this mixture is just right within the firebox during the normal burning process.

If the combustor is running at or above the ignition temperature of the mixture, spontaneous combustion will result, causing the stove to vent puffs of smoke.

Softwoods used for firewood

If softwoods are your only choice, your best options are:

Yellow Pine, Douglas Fir, and any of the Cedars.

Yellow Poplar is a poor wood for fire fuel. Though it burns and splits easily, it emits some heavy smoke and many sparks.

Southern Yellow Pine easily burns at varying heat levels and is easy to split. It emits some smoke and sparks but makes a relatively good firewood.

Douglas Fir is easy to burn and burns at a high heat level. It is easy to split and doesn't throw many sparks, but because of its smokiness Douglas Fir is just rated as a good source of fire fuel.

Cypress and Redwood are fair softwood sources of fuel. They are both somewhat easy to burn and burn at medium heat levels with some smoke and no sparks.

White Cedar or Western and Eastern Red Cedar all burn at low heat but are very easy to burn. They are easy to split, however they emit some heavy smoke and lots of sparks.

White Pine, Sugar Pine and Ponderosa Pine all easy to burn and burn at low heat levels. They are easy to burn and easy to split though they smoke some and spark a small amount.

Tamarack or Larch both burn at medium heat levels, are easy to burn and split but they both smoke and spark. They are fair sources of fire fuel, but not the best of the softwoods.

Spruce is a poor source of fire fuel because it burns at low heat, it smokes somewhat heavily and sparks considerably. Spruce wood is easy to burn and split but is not the best choice for firewood.

Best firewood for burning.

Any dry hardwood will work well, but for keeping your chimney clean, stay away from pine or other pine type trees that have a heavy pitch/sap content.
Make sure all firewood is season dried.

Oak is a favorite because it is a very dense hot burning firewood, that cuts and splits easily.

Birch also burns well, but because it is a less dense wood will burn faster (a good fire starter). Where efficiency is concerned any hard wood that is dry and you can get it cheap or free, that's what you might want to go for.

Elm and Box Elder are good, but they are hard to cut and split. However, they burn fine once you get them dry.
Local saw mills will sell their trimmings (slab wood) quite cheap and it only needs to be cut to length.
So you have to factor in what your expenses are (truck, trailer, chain saw, log splitter), cost of the wood, delivery, the system your using to burn it and of course your time and availability.

Catalytic wood burning stoves will deliver a longer more efficient burn, while cutting back on fuel consumption.  (More heat output for less money)

Wood vs Oil and Gas as a fuel to burn

The news is full of reports about the need to reduce the production of the so-called greenhouse gases.
Fuel burning is the main cause of the increased levels of atmospheric carbon dioxide.
When the atmospheric concentration increases, these gases, mainly carbon dioxide, cause the average global temperature to rise with potentially disastrous results.

Wood, however, differs from the fossil fuels such as oil and gas because it is a renewable fuel. 

As a tree grows, it absorbs carbon dioxide from the air and stores it in the wood as carbon. This carbon makes up about half of the weight of wood.

When wood is burned, carbon dioxide is released again to the atmosphere. The same amount of carbon dioxide would be released if the tree died and were left to rot on the forest floor. Our forests can be a perpetual source of fuel, provided they are cared for and managed properly.

Burning seasoned dried wood in an EPA approved catalytic appliance, provides us with clean air to breathe.
