Disclosed is a feed mechanism in which a ram fed from a feed hopper is configured to compress a fuel against a closed valve which is then opened for the ram to push the fuel to fall into an intermediate chamber. The ram is provided in the feed mechanism between the valve and a rotary scroll feeder of the feed mechanism to assist the break up of the fuel. The rotary scroll feeder delivers the fuel to a heated processing vessel. The length of the ram is such as to close the base of the feed hopper and thus prevent fuel entering behind the ram when in the extended position, and open the base of the feed hopper when in the retracted position. An outlet pipe of the feed mechanism is configured for insertion into the heated processing vessel and is water-cooled.
