ABSTRACT:
A gas generator for operation on a fuel of fine-grained coal which includes a steam boiler, a combustion boiler and a stack leading from the combustion. chamber to the steam boiler. The steam boiler is provided with a slanting bottom portion for the discharge of fly ash and slag. The stack from the combustion chamber to the boiler is composed of a gas outlet pipe attached to the combustion chamber and a gas inlet pipe leading to the boiler. The gas outlet and gas inlet pipes are connected by attaching means. The gas inlet pipe has a double wall of which the inner wall with its top extends freely into the slanting bottom portion of the boiler and thus is adapted for axial heat expansion. The outer wall is provided with a heat expansion compensator and is connected with its top end to the said slanting bottom of the boiler and with its bottom end to the connecting means between the gas inlet and gas outlet pipes. The inner wall of the gas inlet pipe may be in the form of a jacket for holding a cooling water.
