Water Handbook - Chemical Cleaning Of Steam Generator ...

There are two basic methods of acid or chelant cleaning: the circulation method and the static (sometimes called fill-and-soak) method. In the circulation method the cleaning solution is intermittently circulated through the unit until the chemical content and the iron and copper content of the cleaning solution reach a constant value indicating the end of the reaction between the solvent and deposits.

Descaling steam boilers Heating Help: The Wall

The pump method is the safest. Most acid descalers will indicate how much scale each gallon will dissolve by weight before becoming neutralized. The Nu-Calgon dissolves 3lb of scale per gallon neutralized. You can get a good indication of how much scale has been removed and make inferences on scale thickness by looking at the heating area in ...

New Experimental Evaluation Strategies Regarding Slag ...

Pellet boilers and pellet stoves are widely used for heat production. But in most cases only specific wood pellets with a low ash content are approved due to the increased risk of slagging and limited deashing capacity. The ash fusion test (AFT) according to prCEN/TS 15370-1 is currently the only standard for the prediction of slagging. This is not feasible for all biomass ...
