Inexpensive process for synthetic fuel production, contained fluidized-bed burner, pyrolysis reactor with layer of fuel & hot material mixture and hot material circulation system. Fuel is heating up to pyrolysis temperature by surrounded hot material in layer. Volatile matter, evacuated from pyrolyser to cooler, is used for synthetic fuel production. Warm mixture of char and bed material is returned to fluidized bed for burning. Heat of burned char used for circulated material heat up and for steam generation. Hot material from fluidized bed is transported to pyrolyser and, after mixing with fuel form layer in pyrolyser. The process may be used for utilization of extremely wide range of fuels. For fuels with low value of fixed carbon content, oil shale for example, the process may be used solely for synthetic fuel production; for coals only part of fuel energy may be transfer to synthetic fuel, rest have to be used for steam generation. Being used as fuel preparation plant for fluidized-bed steam boiler, the process also dramatically improve its parameters.
