Wet ashtray for boiler systems, consisting of utility model 1 854 112). from a collecting container filled with water, S The discharge chute of the well-known wet ashtray in its water bath the discharge chute normally protrudes to a good and safe conclusion The ash funnel is immersed in an endless conveyor with the immersion nozzle about 20 cm into the water chain for discharging the in the collecting container into the collecting container. Through the heat seal Ash and a support table to support the pipe system can be used at high output of the zen of the upper run of the conveyor chain below the io boiler the expansion down into the Wssssr discharge chute, characterized in that the basin of the collecting container can be up to 50 cm, so that the support table as one of the shape of the collecting tank is then immersed in a depth of up to 70 cm container (2) adapted, rectangular, to the En- large differences in the immersion depth are through the open tub (7) is formed, which by means of the usual in modern boilers hanging the between the discharge chute (3) and the longitudinal 15 steam generation system on the boiler roof the trough arranged anchor (8) on the thing.

In this case step because of are. the large water in the discharge chute 3. wet ashtray according to claim 1, characterized by the amount of water when the glowing slag is extinguished, that to guide the upper run parts explosive pressure surges, whereby the The conveyor chain was bent up on the or, to a small extent, on the walls of the collecting container from the bottom of the tub (7) at the beginning of the can. Furthermore, damage to the guide and at the end of the trough of the vertical movements of the conveyor chain, to the water and electrical arguments the tub following guide elements (16, fittings, etc. occur that lead to operational disruptions) are arranged. considerable extent, e.g. B.

Also preceding claims, characterized by large falling into the furnace draws that water supply and water drainage initially adhering ash caking of the gel organs for the water level in the collecting container wet bag are so heavily filled that the ter (2) due to the discharge chute (3) or the lower run of the conveyor chain is no longer in position Tub (7) are controllable. 40 is, the resulting quantities out of the container 6.

Corresponding probes (19) are connected, whose im- 45 This deficiency is the task of the pre-pulse an invention that determines the water level in the collecting container. ter (2) via pipes (20, 21) regulating pump, this task is essentially solved ert. by that the support table as one of the form of on Catch container adapted, rectangular, at the ends - ■ 50 open tub is formed, which means between Outlet chute and the longitudinal edges of the trough arranged anchor is attached to the outlet chute The present invention relates to a Naßent- and to this - regardless of the immersion depth ashtray for boiler systems, consisting of a with - is kept at a constant distance.
With this new design of the wet ashtray, the discharge chute of the ash funnel is reached so that the distance between the lower edge of the dips, an endless conveyor chain for discharging the discharge chute from the upper run of the conveyor chain or the ashes deleted in the collection container and one of the supporting surface of the upper run is always the same size support table for supporting the upper run of the conveyor. This will overload the upper run chain below the discharge chute. 60 prevents the conveyor chain and it succeeds The drive for the conveyor chain is proportionately even distribution of the underside on the upper part the rising part of the collecting container causes different masses of ash due to the orderly, while the Spiann station is on the other upper run to achieve the most even-end possible of the collecting container that is horizontal there, the lower run of the conveyor chain is loaded. A det. At the transition from the horizontal to the diagonally 65 touching the conveyor chain through the immersion nozzle rising part of the collecting container, the for- is excluded. The chain with the upper and lower run via deflection is also ensured by keeping the roll-off constant guided. of the tub from the immersion nozzle of the
