A radiant burner for treating an effluent gas stream from a manufacturing processing tool includes a plurality of treatment chambers, each treatment chamber having an effluent stream inlet for supplying a respective portion of the effluent gas stream to that treatment chamber for treatment therewithin. In this way, multiple treatment chambers may be provided, each of which treats part of the effluent stream. Accordingly, the number of treatment chambers can be selected to match the flow rate of the effluent gas stream from any particular processing tool. This provides an architecture which is reliably scalable to suit the needs of any effluent gas stream flow rate.

A combustion chamber for use in the incineration of waste products includes an inner refractory wall which extends vertically within an outer protective wall in a spaced relationship so as to define a plenum therebetween. The inner refractory wall is constructed using a plurality of precast, refractory blocks which are stacked and arranged to define a cylindrical interior cavity. The refractory blocks include mating features on adjacent surfaces to facilitate assembly and provide structural support. For additional support, selected blocks are fixedly connected to vertical support tubes by metal tie-back anchors. To facilitate combustion, a selection of the blocks is precast with a tuyere hole in order to deliver a uniform and balanced supply of air from the plenum into the interior cavity. The precast nature of the refractory blocks enables the inner refractory wall to be constructed with great precision, thereby optimizing incineration and minimizing material degradation.

A plant for the treatment of materials, in particular waste materials and refuse, comprises a combustion reactor to which the material to be treated can be supplied. The combustion reactor has an input for a combustion supporter comprising oxygen and an output for the gases that are produced during the combustion of the materials inside the reactor and, in use, is substantially isothermic or quasi-isothermic at high or very high temperature, and without substantial oxygen deficit, in all of its parts. A portion of the combustion gases is recirculated and mixed with the combustion supporter to bring about a high degree of opacification thereof, which is increased by increasing the total pressure of the combustion chamber. The substances which cannot be gasified inside the reactor are immediately fused. The parameters of the gases at the output from the reactor are constantly measured by sensors with response-time characteristics of about 2 seconds.
