To calculate heat losses with flue gases of coal-fired boilers

Abstract

The article is devoted to solving the problem of increasing the efficiency of solid fuel boilers ’ blast control systems. Existing algorithms for calculating losses with outgoing gases, the value of which determines the efficiency of the boiler blow control system, have significant disadvantages due to either high complexity of calculations or insufficient accuracy of the Siegert formula. The authors of the article experimentally confirmed the limitations of practical application of the Siegert formula in the logic of solid fuel boiler blow control systems. To eliminate the identified shortcomings, a new formula for calculating losses with outgoing gases is proposed, which can be used in solid-fuel boiler blast control systems, which has a sufficiently high accuracy and, at the same time, low computational complexity.
