TL;DR: In this paper, a method and device for evaluating outlet temperature optimization and energy-saving effects of coal mills is presented, which comprises the following steps of: obtaining a heat balance equation, obtaining a relational expression between inlet air temperature change and outlet air temperature changes of a coal mill according to the heat balance equations; obtaining a hot primary air increase proportion caused by outlet temperature promotion of the coal mill, and obtaining a proportion of a hotprimary air volume in a total primary air volume under any operation condition of a unit; and obtaining smoke discharging temperature reduction numerical value, at

TL;DR: In this paper, an automatic superheated steam temperature model gain identification method and system was proposed to identify and correct the gain of an advancing differential loop differentiator online, and therefore the dynamic response and static response of a controlled object are improved.

TL;DR: In this paper, a control method of a deaerator water level during the throttling process of condensation water was proposed, which comprises the steps of acquiring a first water level deviation value, a preset deviation adjustment highest speed and a preset deviations adjustment speed change rate, generating a deviation adjustment waveform, adjusting the water level of the deaerators and enabling the final water level to be equal to the preset standard water level.

TL;DR: In this paper, the authors proposed a secondary air online measuring method for a turbulent burner, where three measuring radiuses are selected in the secondary air duct, and the radial cross section is divided into four annular regions by the three radiuses.
