The method of combustion process quality evaluation is described as well as the influence of woodchips moisture content on combustion process. According to the experiments moisture content influences the excess air ratio but only minimally. As with increasing of moisture content from 10% to 60% necessary excess air ratio will increase only by10-15%.The value of excess air alpha -n represents values and reflects intrinsic ratios of excess air ratio depending on the fuel moisture. Alpha - n changes from 1.43 to 1.76 with the fuel moisture content 10-30%. This is only minimal increase and according to the measurement realizes only about 2.2% of total increase. With the subsequent increments of moisture above 30% represents an increase of excess air ratio to about 0.11-0.15 for every next 10% of the fuel humidity. Increasing of this value with increasing of values of the fuel relative humidity can explain the mechanism of moist air combustion. Alpha -d is determined by calculations on the basis of the represented mathematical model and is compared with measured values alpha-n. In this case Alpha -n reflects the fair value of excess air ratio and therefore appropriate to use it. According to the results it is necessary to have online information about the amount of oxygen, carbon dioxide and carbon monoxide in exhaust gases especially in combustion with low excess air ratio or high moisture content.
