Non-Seasoned Firewood

This unseasoned fire shows no end cracking and the bark is not lifting off. 30to 50% moisture content. This wood has been split to a good size and needs to dry in direct sun light with flow through air until end cracking is achieved.

VOR-TECH Combustion Chamber
of the
G-Class Furnace

 

The G-CLASS POLAR Outdoor Furnace Vor-Tech Combustion chamber burns 99.5% efficiency meaning a hot burn with very little waste resulting in all fire no smoke!

To get perfect combustion the right amounts of fuel(wood), heat, and oxygen (air) need to get thoroughly mixed with each other. 

 

This is exactly what happens at the heart of every G-CLASS Furnace inside the VOR-TECH combustion chamber. Preheated secondary air (oxygen) is mixed with the hot unburned smoke and gases (fuel) as they flow down into the VOR-TECH chamber from the primary chamber above. The incoming gas flow is angled to encourage a swirling vortex inside the cylindrical chamber. The resulting 1700 - 2000°F vortex mixes the unburned smoke with the preheated secondary air and the results are truly amazing. Combustion efficiency reaches 99.5%. This means that every piece of wood and all the smoke and gases are burned. Every BTU of energy stored inside the firewood is released from the wood and becomes available to transfer into the water jacket to heat your home or shop or anything else that requires heat.

Understanding The Combustion Process

 

Wood heats up to approximately 212F, evaporating the moisture from the wood. There is no heating from the wood at this time.

 

Near 575F, wood solids start to break down converting the fuel gases.

 

From 575F to 1100F, the main energy in the wood is released when fuel vapors containing 40% to 60% of the energy, burn.

 

After evaporating the moisture and burning the fuel vapors, only charcoal remains, burning at temperatures higher

 than 1100F.

Features On The Back of the
G-Class Furnace

 

The G-CLASS POLAR Outdoor Furnace, rear features video is a general overview and educational video. It shows the different features of the Polar Furnace G-Class with a few details to educate you about this first in it's class of gasification wood burning furnaces.

DEMANDS -VS- FUEL CONSUMPTION

The average home will require approximately 30 btu's per hour of heat (per square foot with 8 foot ceilings) of living area to maintain a normal level of comfort. It has been said that an older two story home in the central North America will require about 200,000,000 BTU'S per year. Many factors such as location, quality and type, age and maintenance, elevation and surroundings of a structure will have a great influence on heat demands and fuel consumption's. 

 

A very important thing to remember about a heating appliance is that, like most things, they need to be maintained.The basic thing to remember is to follow the manufacturer's instruction manual.

Manufacturers know their product and they want this product to perform at its best so they get a positive referral from you the customer.

Most heating appliances, which burn a fuel and transfer the thermal energy to some sort of a surface, will need to be cleaned from time to time. If not cleaned, this build up insulates and reduces your efficiency. Also all air intakes and exhaust as well as ducting and filters need to be free of restrictions and will very on the amount of maintenance they require due to your heating practices.

It is also important that in the case of wood,corn,coal and any other similar fuel types, that the moisture content is not higher than 20%. Remember that a fireman puts water on a fire to cool it down. There are three parts to combustion. FUEL-OXYGEN-HEAT. Take any one away and you have no fire. The best fire for a heating appliance will require a controlled amount of each. An understanding of this and how it pertains to your appliance and fuel choice, will give you a much improved performance and efficiency.
