FIELD: process engineering.
SUBSTANCE: invention relates to exhaust gas treatment. Proposed unit comprises combustion chamber and heat exchanger to transfer heat generated by purified gas generated in combustion chamber to green gas fed thereto. Note here that said heat exchanger allows internal fluid to flow through internal heat exchanger chamber and external heat exchanger chamber for control over purified gas outlet temperature. Note here that said unit comprises bypass device with separator. Said device separates said bypass flow from the external residual fluid flow. Mixer is used to add fluid bypass flow to residual fluid flow after the latter flows through the section of said external heat exchanger chamber.
EFFECT: controlled outlet purified gas temperature.
