PLASMA FIRED STEAM GENERATOR SYSTEM

PYROGENESIS CANADA INC., ...

1. A method for generating steam, comprising:providing a steam generator;
feeding dirty water to the steam generator; and
submitting the dirty water to at least one submerged plasma arc and to resistive heating, such as to generate high pressure steam, wherein an endless screw mechanism is provided for controlling a relative position of electrically conducting electrodes and thus independently controlling a current for each AC phase and a power input to the steam generating system.

METHOD TO MAXIMIZE ENERGY RECOVERY IN WASTE-TO-ENERGY PROCESS

PYROGENESIS CANADA INC., ...

1. A fossil fuel waste incineration or plasma gasification process, wherein waste heat generated by a combustion of waste
is captured by a heat transfer fluid and conveyed to an Organic Rankine Cycle (ORC) for energy recovery, wherein the waste
thermal energy in the process is recovered by cooling of the various thermal components with a liquid and by using the liquid
to quench a hot process exhaust.
