A heat treatment apparatus has a first screw conveyor, a second screw conveyor, a first nozzle pipe, and a second nozzle pipe. If the first screw conveyor rotates right, the first nozzle pipe is disposed on the left lateral side of the first screw conveyor. If the first screw conveyor rotates left, the first nozzle pipe is disposed on the right lateral side of the first screw conveyor. If the second screw conveyor rotates right, the second nozzle pipe is disposed on the left lateral side of the second screw conveyor. If the second screw conveyor rotates left, the second nozzle pipe is disposed on the right lateral side of the second screw conveyor.

An optimization method for a directional preparation technique and efficient use of semi-coke for blast furnace injection. Firstly, the volatile and the ash content of target semi-coke are preset, and then the volatile and the ash removal percentages of a raw coal are calculated; after ash removal, several sets of dry distillation carbonization temperatures and carbonization times are obtained according to the volatile removal percentage, and the relationships between a combustion rate, abrasiveness, explosiveness and jet flow property and the carbonization temperature are respectively established to obtain the optimal actual carbonization temperature; and semi-coke for blast furnace injection is obtained at an actual carbonization temperature. The directional preparation is suitable for the semi-coke for blast furnace injection, and an optimal coal-compounding scheme is obtained, thus achieving the efficient and safe injection of blast furnace iron-making fuels, and energy conservation and emission reduction.

Waste, such as municipal solid waste (MSF), is separated into a wet fraction and refuse derived fuel (RDF). For example, the waste may be separated in a press. The wet fraction is treated in an anaerobic digester. The RDF is further separated into a cellulosic fraction and a non-cellulosic fraction. The cellulosic fraction is treated by pyrolysis and produces a pyrolysis liquid. The pyrolysis liquid is added to the anaerobic digester.
