One kelvin represents the same temperature difference as one degree Celsius. In 1967 the General Conference on Weights and Measures defined the temperature of the triple point of water (the temperature at which water exists simultaneously in the gaseous, liquid, and solid states) to be exactly 273.16 kelvins. Since this temperature is also equal to 0.01¡C, the temperature in kelvins is always equal to 273.15 plus the temperature in degrees Celsius. The kelvin equals exactly 1.8 degrees Fahrenheit. The unit is named for the English mathematician and physicist William Thomson (1824-1907), later Baron Kelvin; he is remembered for his pioneering work on the physics of heat. Your temperature of interest is 292K or about 15C or Fahrenheit 59F Thanks for your explanation and conversion factor. If I do the calculation I get about 19C and 66F ? Groeten, Peter. Yahoo!

Somewhere els, I read, that glycerin should burn at very high temperature, because acreolin is released when temperatures are to low. Acreolin is highly toxic, as I was told.

For that reason I only use my 'mix' in combination with a wood fire that already has been running for a while. The stove used is cast iron and equipped with a good quality chimney ! Note: for practical use the mix is cast into small logs using empty 1 liter milk cartons. Met vriendelijke groeten, Peter. Yahoo! Groups Sponsor -~-- Get A Free Psychic Reading!

[biofuel] New application for glycerin waste ?
Hi All, First let me do a quick introduction of myself: -new to this forum but not unfamiliar with small scale biodiesel production (been brewing and improving for 1.5 years now, currently using base/base method). -first name is Peter, most friends know me as roughscience.. Now to the glycerin: In winter I do not have a glycerine waste problem: a glycerin/sawdust mixture makes excellent fuel in a wood stove ! In summertime however the amount of our dark glycerin/soap mix keeps piling up. Last weekend I was looking into a table with physical properties of glycerin: m.p. = 292 K and 'melting heat' = 175000 J/Kg (anyone able to convert these values to Fahrenheit and Btu/Gal ?). This means that glycerin is able to store a significant amount of heat when it melts, this energy is released again when the glycerin solidifies. Example: the amount of heat released when 1 kg of glycerin solidifies is sufficient to increase the temperature of the same amount of water by more then 40 K. These physical properties theoretically make 'biodiesel-waste' -grade glycerin an interesting heat-storage medium in a solar heating system. I intend to test this idea in the course of this summer. In the meanwhile I would welcome any comments, concerns, additional ideas etc. Met vriendelijke groeten, Peter. Yahoo! Groups Sponsor -~-- Get A Free Psychic Reading!
