| 55,000 BTU Woodgas Outdoor Fireplace  The Woodgas Outdoor Fireplace is the latest addition to the Woodgas line of Stoves after the LE and XL models designed for portability and camping needs. Continuing the development of it's Woodgas Stove product line, Spenton LLC the manufacturer, has made available to the market the most powerful Woodgas Stove yet. The Woodgas Outdoor Fireplace generates 55,000 BTU's of heat from clean biomass energy sources, primarily wood pellet's, sticks, branches, and logs split into smaller sections etc... The unique woodgas technology pioneered by Dr. Tom Reed makes the Outdoor Fireplace highly efficient compared to open pit fires and other biomass heating methods with an efficiency of up to 90% greater than the tried and true 3 stone fire. The Woodgas Fireplace also known as the Woodgas MEGA by leading online retailer of Woodgas products iENERGY Inc. and is the third in the series of Woodgas Stove designs being preceeded by the Woodgas Camp Stove LE and the Woodgas Camp Stove XL models. The smaller LE and XL models are designed for camping and backyard cooking needs while the Fireplace is much heavier, higher capacity and has a far higher heat output being over 4 times greater than the XL the larger of the two Camp Stove models. Several things make the Woodgas design different and superior over other camp stove designs that utilize natural biomass fuels. The Woodgas Stoves use a gasification process wherein air is introduced into both bottom and top sections of a chamber that holds the cooking fuel. A small quantity of air is fed into the bottom section of the combustion chamber and first turns a woody fuel such as sticks into a combustable gas also called "Woodgas", then the gas burns with just the right amount of air injected through a series of burner holes above the fuel bed generating a clean hot flame of the highest efficiency possible. The Woodgas Stoves burn from the top downward and use a small fan which controls the airflow to the combustion chamber. There are many web sites on the internet that show how to build Woodgas Stoves, but the vast majority of them don't include a fan to feed the burning fuel the right amount of air, the "fanless" woodgas stoves are also called "passive draft" designs because the draft air to feed combustion is generated just from the convection of hot air rising. Passive draft designs were found By Dr. Reed over 10 years ago to both generate much less heat and to have a lower efficiency and produce a much dirtier and sooty flame which blackens pots much more readily, this is because the flame doesn't get adequate oxygen and mixing with air without using a fan or "forced draft" techniques. Also, the homemade designs usually instruct to use materials such as soup cans which are made of thin mild steel and don't withstand the high heat of combustion for very long before failing, wheareas the Woodgas Stoves fuel chambers are made of quality materials designed to hold up to the high temperatures generated by the Woodgas combustion process. write your comments about the article :: © 2010 Construction News :: home page |
