Definitions

  • the present invention relates to a combustion grate according to the preamble of claim 1.
  • Rust coating cooling systems are also known, such as the Cooling of the grate by the air flowing past in the air funnels Combustion air or the forced cooling of the Rust deposits from the combustion air, which is caused by a Space made up of the grate bar and a baffle, is pressed into the firebox.
  • Water cooling of the grate is also known the amount of water intended for cooling the grate covers the grate at an approximately constant temperature, independently on the calorific value of the fuel. Again, this is a Disadvantage when burning fuels with lower Calorific value because heat is extracted from the combustion chamber. In this The case would be a higher casting surface temperature for the combustion advantageous.
  • the object of the present invention is now one to further improve such rust and in particular a to ensure reliable tempering to the Optimize combustion of the fuel.
  • FIGS. 1 to 7 The invention is shown in FIGS. 1 to 7 on an air / water cooled combustion grate, which explains how it works is designed as a moving grate. It can be done the invention but without problems on other grate designs apply, such as pyrolysis grate, degassing grate, gasification grate, Incineration grate, high temperature incineration grate, cooling grate, Transport grate, counter-running grate, counter-moving grate, back-moving grate, Roller grate u. the like
  • the feed grate 1 shown schematically in FIG. 1 serves to the fuel and that from combustion To transport slag through the firebox and at the same time to function as a combustion air distribution device.
  • the grate consists of several zones that are horizontal or inclined are arranged.
  • the individual zones can be on the lie on the same level or be separated by a fall.
  • Each individual grate zone consists of fixed and movable Grate levels with fixed grate bars 3 and movable grate bars 2.
  • the movable stages are with variable number of strokes pushed back and forth, which transports the fuel and is turned. The number of strokes is from the fuel and depending on the combustion process.
  • the combustion takes place in the fuel layer through which the combustion air, So-called underwind, from below through gaps in the rust covering 22 (Fig. 2) is blown into the combustion chamber.
  • the gap between the individual grate bars 2 or 3 must be so small that as little unburned as possible Small parts can fall through. These are columns all evenly distributed over the entire grate surface.
  • the stroke length and the stroke speed of the movable grate covering 22 of the individual rust zones 20 is dependent on the Heat release set on grate 1 or in the combustion chamber.
  • the coolant for the feed grate 1 is via distributor 5 fed and after flowing through the grate bars 2 or 3 collected in collectors 6 and returned.
  • a coolant not only water can be provided, but in particular also liquids with higher boiling points, for example certain oils. But it is also possible with help the control system shown in Fig. 1 the liquid heat up and thus when the feed grate flows through 1 if necessary, give off heat to the grate.
  • this water or the liquid flowing through the grate in can be cooled or heated in a heat exchanger.
  • Another heat exchanger in the water network is used for heating or cooling the underwind.
  • a temperature sensor or a temperature measuring point can be a desired one Temperature in the firebox, especially the temperature of the downwind after leaving the grate 1.
  • appropriate regulation of the flowing through the grate Liquids can raise the temperature of the downwind or be reduced, depending on the control program envisaged, to adapt this in particular to the specific type of fuel is.
  • the coolant flow is indicated by corresponding arrows.
  • FIG. 2 shows the feed grate 1, which has three grate zones 20 having.
  • the grate bars 2 and 3 are on grate slides 21 stored and have a grate facing the firebox 22 on.
  • On the underside of the feed grate 1 are air funnels 23 provided which air zones 24 define.
  • FIG. 3 shows an enlarged side view a grate with fixed grate levels 27 and movable grate levels 28.
  • a grate serves a grate 30 and for the supply of the Coolant in the movable grate 28 a feed line 31.
  • FIG. 3 also shows a feed water cylinder 33, which the displacements of the movable grate steps 28th Takes into account.
  • FIG. 5 and 6 show details in perspective an air / water cooled grate bar in simple Execution. It can be a movable grate bar 2 or a fixed grate bar 3 act.
  • This grate bar with the grating 22 has a partition 40 in its interior so that a first cooling chamber 41 and a second cooling chamber 42 lying parallel thereto is created.
  • a water flow opening at the front end of the grate bar 2 or 3 43 This establishes the connection between the two cooling chambers 41 and 42 ago.
  • the partition 40 corrugated baffle 45 which is the heat exchange elevated.
  • the grate bars 2, 3 can be pivoted on a grate shaft 46 stored. Immediately below the grate shaft 46 a distributor 48 supporting the grate shaft 46 and under this a collector 47, which in connection with the cooling water supply 50 and the hot water return line 51 den Ensure the coolant flows through the grate rod.
  • Fig. 7 shows a turning grate bar 60, which on a grate bar support 61 is pivotally mounted. Below this grate bar support 61 is also a supporting coolant distributor 62, combined with a collector 63.
  • One cooling chamber 65 has a corrugated baffle 66 equipped. In this case, one is made of a metal hose existing connecting line 68 is provided, which Thermal stress-free connections for the flow medium ensures.
  • a bearing shell 70 is also provided at its front end, so that, according to any uneven wear of the grate 22, the turning grate bar 60 rotated and the front bearing shell 70 are placed on the grate bar support 61 can.
  • Corresponding connection and connection points are at the front end of the turning grate bar 60, as can be seen, intended.
  • Another special feature of the invention is that Incineration of low calorific value from the liquid cycle heat removed from the grate bar by means of heat exchange between grate bar and combustion air, which very intense due to the geometric shape of the grate bar is released into the combustion air and thus the combustion of the rubbish lying on the grate is accelerated.
  • the cooling creates advantages in the Incineration of waste with high, but also with low calorific value, since the heat extracted is used by the combustion air can be fed again.
