Abstract

A furnace 1 comprises a reactor chamber 7 in a housing 3, with a core element 12 mounted in the reactor chamber. A fuel-fired start-up burner 8 is mounted on the housing and generates an operating temperature of at least 1500 degrees C in the reactor chamber. A steam injector 10 mounted on the housing injects de-aerated steam into the reactor chamber to maintain the operating temperature when the start-up burner is switched off. The steam injector may be connected to a steam generator (16, Fig. 2). The core element may comprise a porous matrix of high temperature fire brick. A thermal treatment chamber 5 may be located above the reactor chamber. A waste treatment system incorporating a furnace and a method of maintaining temperature in a furnace is also claimed.

Brief Description of the Drawings
The. inventon will be more clearly understood by the following description of some embodiments thereof, OiVen by way of example oniy; with reference to the ediximpanying drawings; in which: rig. 1 is a schematic illustrating of a waste treatment plant incorporatino furnace according to the invention; and Fig. 2 is e schematic illustration of a steam generator for uee with the furnace of the invention.
Detailed Description of the Preferred Embodiments
Referring to the drawings, there is ihustrated a face according to the invention.
indicated generally by the reference numeral 1. In this case the furnace. 1 is incorporated in a waste treatment system indicated generally by the reference numeral 2 which may, for example, he a dry distillation type incinerator of the type 4 -described in US 5,195,449.
The. furnace 1 is formed in a housing a above a residue bunker 4 end beneath thermal reaction area:5 which receives waste.materials through a damper S. at a.top of the thermal reaction area 5 for distillation of the waste materials within the thermal reaction area 5.
The furnace I has a reactor chamber 7 formed y'athin the housing 3. A fuel-fired primary: or start-up burner 5 is mounted at a side of the reactor chamber 7 and is operable to generate an operating temperature of at least 1500 t within the reactor chamber 7. A steam injector 10 ia mounted on the housing 3 at a side of the reactor chanter 7 and is operable for injecting de-aerated steam into the reactor chamber f at the operating temperature to maintain the operating temperature within the reactor chamber when the start-up burner 'S is s'vvItched off.
A core element 12 comprising a porous matrix of high temperature firebrick is mounted within the reactor chamber 7 to help rriaintain a:steady operating temperature of between 1500:'C and 20(0 °C within the reactor chamber 7. The core element can vary considerably in size depending on the size of the reactor chamber. An example c)f a typical core size is 100cm high (with 60 spaces) x 150cm wide (with 100 spaces) x 200crn iong (with 200 spaces). The spaces are holes or gaps in the core elarnent 12. For different applications the core element 12 size and shape will change, For example, a cubic, a cylindrical or a spherical core element 12 could he provided. Other core element shapes are possible also The de-aerated steam injector 10 connects via a de-aerated steam feed line 14 with a de-aerated steam generator indicated generally by the reference numeral 16. The de-aerated steam generator 1$ has a water boiler 17 having a water heating tank 18 with a water inlet 19, a water outlet 20 and a de-aerated steam outlet 21, A water inlet valve 22 is mounted at the water inlet 19. A steam outlet vaive 23 is mounted at the de-aerated steam outlet 21. As the water heal ng tank 18 operates under a vacuum, de-aerated steam is generated at a relatively low temperature.
A water tank 25 is mounted directly above the water heating tank 18 and connects thereto, a Water outlet 26 Communicating through the. water In at valve 22 with the water mkt 1$ of the water heating tank 18, ,A water teed pipe.4 communicates between the Water outlet 20. of the water. heating tank 18 and a water inlet 29 of the water tank 25. A pump 30 in the water feed pipe 28 it operable t fwd water from the water heating tank 18. to the water tank 25. The water is circulated through a three-way filling valve 3.2 which also connects Via a water filling line 33 with a water supply which may be A water reservoir, or a mains, water supply. The de-aerated stearl teed line 14 also connects through a Valve 35 with the water tank 25. A beating coil 36 is mounted Within the water heating tank 18, The de-aerated steam generator 1.6 is operable to generate de-aerated steam devoid -Of any air. The water heating tank la is filled conioletely with water to remove all ar Tis water is then pumped by means: of the pump 30 into the water tank 26, thus creating a vacuum within the water heaflOg tank 18. The water heating tank 18 is then partially filled With water from the water tank 25 deliVei'ed through the water inlet valve 22. Operation of the heating 01 36 then heats the water within the water heating tank 18 to generate low pressure: de-aerated steam, devoid of air, which iS delivered through the de-aerated steam feed line 1.4 to the steam injector 10 for com.huSton within the reactor chamber 7, In use, the start-up burner 8 is operated using a hydrocarbon fuel to generate an operating temperature of at least 1500 °C, and preferably about 1500°C to 1600°C, within the reactor chamber 7 Over a period of about 20 minittes. the core element 12 is heated up to this temperature. When the desimd.operating temperature has.be,tri reached de-aerated steam is delivered into the reactor chamber 7 by the wean' injector 10 to maiiitain the operating temperature within the reactor chamber 7 when the start-up burner 8 is turned off. De-aerated steam injected into the reactor chamber 7 is split into hydrogen and oxygen which combust within the reactor chamber 7 to produce high temperature gases which migrate into the thermal reaction area for use in the distillation of the waste materials. The de-aeration of the steam prior to. Injection into the reactor chamber 7 advantageously helps to diminate nitrogen from the reactor chamber 7.
It will be noted that the core element 12' within the reactor:chamber I' Is constructed from high temperature firebrick and is constructed it a design that Slows the core 12 to Maintain a tenterature of 1500°C to 2000. 'C conatanfiy by the cOMbuetioh of the de-aerated steam (H20). CoMbOstion. of de-aerated steam (h10) within the reactor chamber 7 maintains a constant temperature of up tip2000 csC using: de-. aerated.SteatO (H20) only Any over temperature, can he.centrolted by allowing some air Mtn the reactor chamber 7 which reduces the rate of cernbutten,.
Carbon dioxide produced during operation of the furnace 1 is converted into carbon monoxide. At the operating temperature pure carbon dusflpowder is injected into the high temperature gases within the reactor chamber 7 which results in a them cal reaction whereby the added carbon bonds with the high temperature carbon dioxide converting it to carbon monoxide, The reaction is as follows: CO; t-C 2C0 Varkaus:gases generated n. the distillation process within the thermal reactien area are treated.er. net trakted in a gat treatment section of the plant by condenaihd, washing or conversion. Hydrogen and carbon gases are condensed into:fue: oils and:energy. No plumes or harmful. gases are exhausted into the: atmosphere., so there is no nebessity for a chimney or Smoke stack in this:.system.
The gases in the reactor chamber 7 are mein carbon dioxide, hydrogen and water: These n.iH react as fellows: CO, + 4H,,,:t CH4 4 2H20 + 39.13 kez& per mole 2.
