Definitions
- Flow, temperature, oxygen and noxious gas distribution are mostly very non-uniform across the cross-section of the radiation trains and cannot be completely eliminated even by a mixing pulse, ie by injection of secondary gas or other gaseous media. Often there are also pronounced ones Strands of combustion gases in which there is a lack of oxygen. They favor signs of corrosion primarily in the radiation lines, but also on the built-in heat exchangers. Due to the non-uniform oxygen distribution, organic pollutants and CO in the flue gas can usually not be completely burned. A required quality of mixing can, however, only be achieved with an injection with parameters in a precisely specified range, which must be adapted in each case when the operating conditions change, for example in the partial load range.
- the combustion process in the combustion chamber can be optimized regardless of the emission values, for example with regard to a reduction in nitrogen oxide on the primary side, with regard to reduced grate temperatures with high-calorific fuel or with minimized amounts of flue gas.
- Any high CO concentrations that occur in the flow are reliably reduced in any case by the oxygen mixing in via the lattice structure.
- Sectoral series connection of several lattice structures additionally enables the flow of the entire flue gas flow to be evened out in a targeted manner and extremely non-uniform flows over the radiation draft in the combustion chamber to be compensated for. This option is particularly interesting for radiation traces with a large cross-section or with a pronounced stratified flow.
- the lattice structure is shown in FIG. 1 as a simply curved lattice surface.
- the production is preferably carried out without pressure by a sintering process, the sintering parameters being set such that the walls of the tubes have open porosity as openings.
- Lattice structures with supply tubes without and distribution tubes with openings in the walls are preferably manufactured in a multi-stage manufacturing process, the supply tubes being processed as finished and densely sintered components in a second manufacturing step.
