Influence of fuel quality on boiler work with retort furance

In the paper the impact of changes in coal quality on boiler operation with the retort furnace had been discussed. Study used a test for the three types of coal from different mines. Energy and emission studies have shown that even relatively coals not much different with physicochemical parameters, causing a marked change of the efficiency of device operation. Attention was drawn to the growing scale of the problem in the application of fuel significantly deviating from properties of the classical fuel to the retort furnaces. The ways to improve the quality of use of boilers with retort burner have been given.
