Abstract
A furnace, and a method of firing it, wherein part of the fuel supplied to the furnace is produced from waste plastics by a depolymerisation process, waste heat from the furnace being used to promote the depolymerisation process. The furnace is equipped with regenerators for waste heat recovery and is fired alternately in first and second opposed directions, with the direction of firing periodically reversing between the first direction and the second direction. The supply of fuel to the furnace is temporarily interrupted while the direction of firing is reversing, means being provided to accommodate the fuel produced during the temporary interruption. The furnace may be used for producing glass.
Claims20
A method of firing a furnace by burning fuel, comprising:
- providing a pyrolysis plant in which fuel is produced from the depolymerisation of waste plastics;
- providing a supply of fuel to the furnace and burning that fuel in the furnace, wherein part of the fuel supplied to the furnace and burnt in the furnace is produced from the depolymerisation of the waste plastics in the pyrolysis plant;
- firing the furnace alternately in first and second opposed directions, with the direction of firing periodically reversing between the first direction and the second direction;
- temporarily interrupting the supply of fuel to the furnace while the direction of firing is reversing;
- and
- during the temporary interruption, diverting at least some of the fuel produced by the depolymerisation of the waste plastics to a storage receiver.
A method of firing a furnace by burning fuel, comprising:
- providing a supply of fuel to the furnace, wherein part of the fuel supplied to the furnace and burnt in the furnace is produced from waste plastics by a depolymerisation process, waste heat from the furnace being used to promote the depolymerisation process,
- wherein the furnace is equipped with regenerators for waste heat recovery,
- firing the furnace alternately in first and second opposed directions, with the direction of firing periodically reversing between the first direction and the second direction,
- temporarily interrupting the supply of fuel to the furnace while the direction of firing is reversing, means being provided to accommodate the fuel produced during the temporary interruption.
A furnace which is fired by burning fuel and a plant for producing fuel from waste plastics by a depolymerisation process, wherein the plant supplies fuel to the furnace, and waste heat from the furnace is used to promote the depolymerisation process, the furnace being equipped with regenerators for waste heat recovery, wherein the furnace is fired alternately in first and second opposed directions, with the direction of firing periodically reversing between the first direction and the second directions, means being provided to accommodate the fuel produced during the reversing of the direction of firing.
