Dear Ken Thanks for asking for assistance - you can render some immediately without perhaps anticipating that!

I have been looking for a method of determining when the water leave the fuel, and what the combustion moisture level is in a chimney. I heard a rumour that one method was to take a sample from the chimney and pass it through CaCl2 in a tube and it would very effectively remove 100% of it. If I do this (which is cheap and easy) I can place the container with the CaCl on a scale and weight the increase in mass using a scale with an accuracy of 0.1 g. What do you think? Is this a viable option? How much water can CaCl absorb? From what I read in your message the material can be recycled. We have masses of free heat as these are 7-15 kW space heating stoves so getting the moisture out will be easy. Somewhat humorous that you are trying to get the moisture out of the CaCl and I am trying to get it in! What would be helpful is an indication of how big such a device should be. The moisture in the stack is sometimes as high as 14% by weight and as low as nearly nothing. If we burn 8 kg of coal with 25% moisture content it means absorbing a sample drawn from 2 litres of water. Drawing in 0.5% of the sample means 10 cc of water to be absorbed. A related question is how hot the CaCl can be and still absorb effectively. Thanks for any ideas you have.
