Abstract

Abstract—Uncertainty assessment is a quantitative method about accuracy grade. This essay mainly focused on the principle of uncertainty analysis, including establish the uncertainty analysis model, assess the uncertainty components of type A and type B, and calculate the sensitivity coefficient and combined standard uncertainty. Because the result is easy to go wrong when using partial differential to solve the sensitivity coefficient, two kinds of mathematical models without using partial differential are put forward. Based on the uncertainty assessment of boiler emission flue gas heat loss, three models are used to calculate the combined standard uncertainty of boiler flue gas heat loss respectively, the results are contrasted and analyzed which certified the correctness of the two new models. In this way, a new calculation method is bought up, as well as simplifying the work of uncertainty assessment.
