A system consisting of two interference filters of different wavelength and two photo-multiplier detectors was used to measure the time evolution of the SCB plasma temperature based on the double line of atomic emission spectroscopy.

The SCB plasma electron density was studied in this paper.

40nm and Saha equation were used to measure the SCB plasma electron density, respectively.

When the heat spread speed is a finite value in the process of plasma ignition,the theory of heat conduction is quite different from the classical Fourier law applied to the process when the heat spread speed is infinite.

Experimental results show that plasma ignition reduces propellant ignition delay markedly.

Influence of charge configurations on plasma ignition performance of propellants and plasma-propellant interactions are studied by interrupted-burning experiments of propellants ignited by plasma.

Application of plasma ignition technology to boilers with tangential firing;

Application of plasma ignition to 1 000 MW ultra-supercritical boilers and its operation analysis;

Application of plasma ignition combustion technique in the thermal power plant for energy conservation and environmental protection;

The system construction and working principle of plasma ignition device are introduced as well as its safe operation as viewed from running.

The plasma ignition devices should be tested before put into use.

In order to reduce fuel oil consumption,plasma ignition device is used in the coal fired boiler of a 600 MW supercritical unit.
