When the filter paper is burned some 'ash' will be left behind.
is ash is an ingrediant of filter paper
0.01 g
acid insoluble ash indicates the amount of silica present in the given sample
Ash Content is usually expressed in % Ash Content & is calculated as follows: % Ash Content = (Sample wt. after drying @ 500-550 Deg C - for 3 Hrs) x 100 (Initial Sample wt. dried @ 105 Deg.C - for 3 Hrs.)
It's obvious, paper come from trees so they turn into ash.
is ash is an ingrediant of filter paper
Ash-less, hardened filter paper is made from high purity cellulose, sometimes washed with HCl and then with HF to remove minerals, and leaving ultra pure cellulose so when the paper ignites it burns completely leaving no ash. the hardening is achieved by washing the paper in nitric acid, which converts the cellulose to nitrocellulose which have more mechanical resistance and is also acid resistant.
Ash content is determined by calcination and deionized water is not necessary.
To evaluate the insoluble content of a substance.
The amount of ash produced during combustion relative to the amount of fuel fed into the wood pellet stove. Ash content is one indicator of quality for wood pellet fuel. Ash content for wood pellets should be between one and three percent. 

Fixed Carbon by Difference = 100 - (Volatile Content + Ash Content + Moisture Content)
Paper is a fuel that is nearly as good as low energy woods such as pine, as long as the paper is tightly compressed. There are tools sold for compressing paper into logs that burn as well as pine logs. ------------------------------------------------------------- For industrial fuels paper has a low heat release, often has a high ash content, requires much excess air, if tightly bound, will not completely burn, and if wet provides severe reductions in combustibility and heat content.
