Definitions
- the invention relates to a waste incineration plant with a Combustion grate with the features of the preamble of Claim 1 (see for example US-3393652-A).
- a defined gap is for the safe operation of the system Of considerable importance, since only so the wear in the Transition area between the combustion grate and the boiler remains controllable.
- Rosttragrahmens require a complex scaffolding structure, because the support tubes on support plates and disc springs in the Hanging boiler stand are.
- the support tubes are in integrate the water-steam circuit of the boiler.
- the invention is based on the object at a generic waste incineration plant the combustion grate so support that on support tubes for the support of the Rosttragrahmens can be waived and that a Relative movement between the combustion grate and the boiler is minimized during operation of the waste incineration plant.
- the Loads from the combustion grate, the grate support frame as well as from the fuel shaft and the slag trap which are connected with the Rust carrying frames are connected, directly into the foundation be initiated, resulting in savings in steel construction for the Kesselgerüst be possible.
- the vertically movable unit Replaces the support tubes for supporting the Rostragrahmens. The elimination of these support tubes also accounts for the Suspension of the support tubes in the boiler tower necessary Plates and disc springs and the integration of Supporting pipes in the water-steam cycle of the boiler. The through the thermal expansion related relative movement between the Combustion grate and the boiler is going through the vertical counteracted movable unit.
- Measuring device By cooperating with the vertically movable unit Measuring device can be the gap between the Combustion grate and the boiler in all operating conditions of Define waste incineration plant exactly.
- About one with the Measuring device connected control unit can be the vertical Movable unit of Kesseldehung controlled controlled , whereby the gap is to be kept constant.
- the waste incineration plant contains a boiler 1 with a combustion chamber 2, to which only one partially shown flue 3 connects.
- the firebox 2 is laterally through the side walls 4 of the boiler 1 and above limited by a firebox ceiling 5.
- the side walls 4, the Combustor ceiling 5 and the flue 3 are gas-tight formed welded together pipe walls and in a Integrated water-steam cycle.
- the boiler 1 is mounted in a boiler steel 15, of which Parts can be seen in Figs. 1 and 2.
- the furnace 2 of the boiler 1 is down through a Combustion grate 8 limited, for example, as a feed grate is trained.
- a Combustion grate 8 In front of the combustion grate 8 is a Fuel chute 9, and behind the combustion grate 8 is a Slag trap shaft 10 is provided.
- the combustion grate 8 is along with the fuel chute 9 and the slag trap 10 on a grate support frame 11.
- the garbage gets over the Fuel chute 9 abandoned on the burn grate, over the Combustion grate 8 in the direction of the slag trap shaft 10 conveyed and under supply of combustion air on the Combustion grate 8 burned.
- the boiler 1 expands through the the heat produced by the incineration of the garbage to the sides and down from.
- the vertically movable Unit consists of several individual elements 12, the various locations connected to the grate support frame 11 and suspended either on a foundation 7 or on a support 6 are.
- the vertically movable unit causes a vertical Change in position of the grate support frame 11 with respect to the boiler 1.
- a vertical position change of the grate support frame 11 requires a horizontal shift option or a swivel option the connection point between the vertically movable Unit and the grate support frame 11 and the foundation 7.
- the Connection between the vertically movable unit and the Rost support frame 11 and the foundation 7 is therefore, as in the Fig. 1, 2 and 3B indicated as a joint 13, z. B. in the form of Ball joint eyes or pin bearings to be executed.
- the Individual elements 12 of the vertically movable unit can also horizontally displaceable on plain bearings or bearings 16 be stored (Fig. 3B). In this way, the Grate frame 11 to move up and down and by one or two Swing axles. Any position can be adjusted which is an optimization of the gap size in all operating states allows.
- the individual elements 12 of the vertically movable unit can get up on the foundation 7 and the grate support frame 11 of support the bottom, causing the load directly into the foundation 7 is introduced (Fig. 1).
- Alterantiv can the individual elements 12 of the vertically movable unit above the Rosttragrahmens 11 suspended from the support 6, whereby the Load is introduced via the carrier 6 in the foundation 7 (Fig. 2).
- the individual elements 12 of the vertically movable unit can as a hydraulic support, as Spindelhubelement, as a rack with Pinion or in the hanging version as a winch be educated.
- a hydraulic support as Spindelhubelement
- a rack with Pinion or in the hanging version as a winch be educated.
- Figs. 3A and 3B one as Hydraulic support trained vertically movable unit shown, which consists of a pressurized medium cylinder 17 and a piston rod 18 is made.
- this is the Drive element - that is, the cylinder 17 of the hydraulic support, the driven nut of the Spindelhubides, the driven pinions - on the fixed part (foundation 7 or carrier 6).
- the counterpart - that is the Piston rod 18 of the hydraulic support, the spindle of Screw jack, the rack - is with the rust carrying frame 11 connected.
- the vertically movable unit acts with a measuring device 14 together, to the grate support frame 11 and the boiler 1 attacks.
- the measuring device 14 provides a manipulated variable for the Adjustment of the gap between the grate support frame 11 and the Boiler 1.
- the manipulated variable is connected to the control unit via a control device driven part of the vertically movable unit forwarded.
- the measuring device 14 may be a path measuring device, with the distance is determined during operation due to the boiler stretching between the combustion grate 8 and the boiler 1 sets. The measured distance is with a previously defined distance compared. Is this defined Distance exceeded, so the Vebren Vietnamesesrost with the Rost support frame 11 by activating the drive part of the Individual elements 12 of the vertically movable unit to the Boiler 1 can be brought up. When falling below the Distance is the combustion grate 8 of the boiler 1 away to be moved. This will clear the gap or the gap between held the Vebren Vietnamesesrost 8 and the boiler 1 constant.
- the measuring device 14 can also be used as a force measuring device be formed, with which the force is determined during the of operation due to the boiler stretching between the Grate support frame 11 or the combustion grate 8 and the boiler 1 takes effect.
- the measured force comes with a previously defined traction compared. Will this defined force exceeded, so must with the help of vertically movable Unit of the combustion grate 8 with the grate support frame 11 to the Boiler 1 are moved up. In a fall below the Force the combustion grate 8 is moved away from the boiler 1. By keeping constant the force between the combustion grate 8 and the boiler 1 is also the gap between these two constant held. The same applies to a previously defined compressive force.
