Solution Overview
Problem
Reactor systems for producing and treating particles in oscillating process gas streams face challenges in optimal regulation due to feedback from fittings, limiting the control over oscillating process gas streams.
Innovation Solution
A reactor system with multiple burners, each equipped with high-precision volume stream regulation devices, such as sliding gate valves or iris shutters, to minimize feedback and allow stable operation, along with a configuration that includes various burner types like ignition, pilot, ring, and swirl burners for flexible energy input and precise control of resonance oscillations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple burners are used in the reactor system, then the flexibility and control over thermal treatment processes are improved, but the feedback from fittings increases, making regulation difficult
Solution Approach 1:
The patent extracts and removes fittings from the channel ducts of the multiple burner system. By eliminating fittings in the fuel and combustion gas supply lines, the system prevents feedback effects that would otherwise disrupt the oscillating process gas stream, thereby maintaining both multi-burner flexibility and stable regulation
Solution Approach 2:
The patent divides the burner system into multiple independent burner units, each with its own channel ducts for fuel and combustion gas. This segmentation allows independent control of each burner while avoiding feedback interference through the absence of fittings in the distributed channel system
2Measurement precision
If volume stream regulation devices are installed in each channel duct, then the precision of oscillation regulation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical regulation systems with volume stream regulation devices that utilize the inherent oscillating flow dynamics. These devices regulate fuel and combustion gas volumes precisely by leveraging the oscillating pressure fields already present in the system, rather than requiring complex external control mechanisms
Solution Approach 2:
The patent changes the operational parameters of the channel ducts by introducing volume stream regulation devices that adjust fuel and combustion gas flow rates in response to oscillating pressure conditions. This allows precise control of the oscillating process gas stream through parameter adjustment rather than complex structural modifications
3Ease of manufacture
If fittings are present in the channel ducts, then the ease of assembly and maintenance is improved, but the stability of oscillating process gas stream deteriorates
Solution Approach 1:
The patent extracts and eliminates fittings from the channel duct system. By removing these potential sources of feedback and flow disruption, the system achieves stable oscillating process gas streams while maintaining assembly simplicity through direct, fitting-free connections in the fuel and combustion gas supply lines

Implementation Method 1
a combustion chamber (6), an exhaust gas pipe (7) that follows downstream from the combustion chamber (6), and a multiple burner system (9) that has a plurality of burners (8)
Implementation Method 2
an oscillation or pulsation of the process gas is used, with the purpose of producing a resonance oscillation, wherein the latter has an influence, in particular, on acoustic, material (in the case of multi-phase systems, for example) and heat-technology properties
