Processes for controlling afterburn in a reheater and loss of entrained solid particles in reheater flue gas are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium comprising combustible solid particles. The spent heat transfer medium is introduced into a fluidizing dense bed. The combustible solid particles of the spent heat transfer medium are combusted forming combustion product flue gas in a dilute phase above the fluidizing dense bed. The combustion product flue gas comprises flue gas and solid particles entrained therein. The solid particles are separated from the combustion product flue gas to form separated solid particles. At least a portion of the separated solid particles are returned to the fludizing dense bed.

A tunnel pyrolysis furnace has a body and at least one flaming device. The body has a chamber and multiple tubes. The multiple tubes are disposed around the chamber and have catalysts loaded inside. The at least one flaming device is disposed near the body, and is used to heat up the body. The multiple tubes absorb heat, so heat is concentrated around the chamber and that provides an effect of even heating. Therefore, the chamber may reach a temperature for pyrolysis in a short time.

Systems and methods are disclosed for pyrolysis of waste feed material. Some systems include a main retort and a secondary retort. Syngas is produced by pyrolysis in the main retort, and is then mixed with combustion air and ignited, in some cases to produce energy. Carbon char travels to the secondary retort and is exhausted from the system through an airlock.
