Various ash removal schemes from the hopper ash collector to such transportation devices as hydraulic ash disposal channels, are analyzed. The drawbacks of these schemes are: high flow rates of flush water, gas flows through common ash gutters between bunkers of different pressure, and clogging of ash flows. The paper considers the invention and its introduction, which will eliminate or reduce these drawbacks by increasing the reliability of the circuits and centralizing the discharge of ash. The high efficiency of the invention under consideration is illustrated by the example of its practical use in the Galachinsk boiler house situated in the territory of Bratsk. To determine the design and operational parameters of the above mentioned invention its mathematical model has been developed based on the balance of forces acting in it (on the continuous gate). With the help of the obtained model, the structural and operational parameters of the device are calculated in three possible variants of its implementation. In these cases, the number of sections of different pressure changes and the presence of a periodic action shutter is taken into account. The determined parameters are the maximum and minimum heights of the ash column, the mass and the position of the load of the continuous gate. Ash collector performance indicators affecting these parameters have been identified. An ash collector of the TsBR-150U-1280 type, which has ash bunkers with three different values of vacuum, is accepted as an example. On the basis of the developed model, an algorithm has been compiled for calculating the design and operational parameters of the device under consideration during its design.
