High Voltage Plasmatron for Stable Nitric Oxide Generation

The patent transforms the operating parameters from conventional high current (1-1000 A) to high voltage low current (100-1000 V, 0.1-10 A) regime. This parameter change fundamentally alters the energy distribution, reducing electrode heating and erosion while maintaining plasma generation capability. The high voltage creates a more distributed energy profile along the plasma channel, preventing localized overheating at electrode surfaces.

The invention replaces the conventional arc discharge mechanism with a glow discharge mechanism. This substitution changes the fundamental physics of plasma generation, using electron avalanche and ionization processes that occur at lower current densities. The glow discharge mode inherently produces less heat at the electrodes compared to arc discharge, thereby extending electrode lifetime and improving reliability.

The patent converts the previously harmful high current density into a beneficial low current density regime. By operating at high voltage low current, the system naturally produces sufficient plasma generation while minimizing harmful thermal effects at the electrodes. This eliminates the need for complex liquid cooling systems, as the electrodes operate within acceptable temperature ranges without active cooling.

The high voltage low current plasmatron design allows the system to self-regulate electrode temperatures through the inherent characteristics of glow discharge. The lower current density automatically reduces resistive heating, and the plasma process itself maintains appropriate thermal conditions without requiring external cooling systems, thereby simplifying the overall device architecture.

The patent enables continuous operation by fundamentally changing the operating regime to high voltage low current. This regime produces plasma with sufficient intensity for productive output while maintaining low enough current density to prevent excessive heat accumulation. The system can therefore operate continuously for extended periods (hours to days) without electrode deterioration, enabling sustained productivity.

By changing from high current to high voltage low current parameters, the system achieves a favorable balance between plasma generation intensity and thermal load on electrodes. The high voltage ensures adequate ionization and plasma density for productivity, while the low current keeps resistive heating minimal, allowing continuous operation without the intermittent cycling required by conventional designs.
