1. A system for the hydrothermal carbonization of a flowable biomass, comprising a pump, a heat exchanger and a tubular reactor, wherein the pump is connected via a delivery conduit for the flowable biomass to the heat exchanger and wherein the heat exchanger is connected to the tubular reactor via a connecting conduit, wherein the heat exchanger contains an insert element and the tubular reactor contains no insert element, wherein the heat exchanger for heating the flowable biomass comprises a duct for the flowable biomass, wherein the duct comprises an inlet opening and an outlet opening, wherein the duct is surrounded by a heatable duct casing, and wherein the insert element is not connected to an inner wall of the duct casing so that the duct casing and the insert element are configured to be movable relative to each other in the duct.
