Definitions

  • the invention relates to a method and a device for the simultaneous generation of heat and hot gas by means of combined heat and power.
  • Such cogeneration systems essentially consist of a working machine, e.g. in the form of an engine or gas turbine, this on the one hand mechanical energy and on the other hand heat, e.g. generate in the form of steam and hot gas.
  • Hot gas is mainly used to dry products.
  • air is heated using conventional burners using conventional fuels and is usually conveyed into the drying oven by means of a fresh air blower. The heat required for other processes or for heating the building is generated separately from the drying process.
  • the main disadvantage of the known method and the device is that, for example, if the dryer fails or comes to a standstill, the system must be shut down, the hot or Exhaust gases are released into the environment unused via a bypass chimney. If the working machine fails, the process temperature at the hot gas consumer is impaired, since it takes some time for the additional firing to take effect via a fresh air blower. If the flue gas flow is controlled by means of throttle valves on the waste heat boiler and the hot gas consumer, the flue gas flow must be throttled with the lowest pressure losses during the operating time. This increases the pressure on the flue gas side and leads to a loss in performance of the gas turbine.
  • the invention has for its object to provide a method and an apparatus for simultaneous heat and hot gas generation by means of combined heat and power, which works without electrical / mechanical performance limitation in the event of hot gas failure from the subscriber without a bypass chimney, fresh fan and throttle devices.
  • This object is achieved according to the method in that the exhaust gas generated by a work machine is divided into a hot gas flow without throttle valves and an additional flue gas flow without throttle valves for heat generation and the hot gas flow for the hot gas consumer is regulated by means of an induced draft.
  • the procedure is such that if the machine fails, the hot gas consumer is switched off from the hot gas line is separated and heated with the connection of fresh air and additional firing.
  • a further process step provides that if the hot gas consumer does not require hot gas, the heat generation is dimensioned such that the additional flue gas flow does not lead to an impermissibly high pressure loss via the flue gas path.
  • An advantageous device for performing the method with a working machine for generating mechanical energy and a hot exhaust gas flow is that the exhaust gas flow is divided into a hot gas line without throttle valves and a line without throttle valves for heat generation, with a controllable suction draft in the hot gas line with the hot gas consumer is arranged while a waste heat boiler is installed in the line for heat generation.
  • An advantageous embodiment provides that the induced draft is arranged downstream of the hot gas consumer.
  • a fresh air line with controllable fresh air flap is connected to the hot gas line.
  • an additional firing is arranged between the hot gas consumer and the fresh air connection and the hot gas line can be separated by means of a butterfly valve.
  • the invention brings considerable advantages in that the waste heat arising from the work machine, for example in the production of electricity can be optimally used for drying purposes.
  • the joint generation of heat and hot gas improves the useful life of the system, since the system can be used better due to the simultaneity.
  • the volume flow can be regulated without exhaust gases having to be released into the environment unused.
  • the hot gas temperature can be regulated as required. Any volume flow can also be set without throttling losses, so that no flue gases are released into the environment unused even when the drying oven is under partial load. A standstill of the drying plant does not affect the operation of the plant. Since no throttling devices are used, there are no additional pressure losses on the exhaust side. The performance of the combined heat and power system is therefore not reduced and thus the efficiency of the system is not impaired.
  • the investments for the throttle valve, the bypass chimney and the fresh fan are saved.
  • a work machine 9 is shown with a gas turbine 5 with furnace 11, which mechanically drives a generator 10 to generate electricity.
  • the exhaust gas stream 12 is divided into a line 13 for heat generation and a hot gas line 14.
  • a hot gas consumer 2 In the hot gas line there is a hot gas consumer 2 with a suction 1 arranged behind it, which is regulated via a flow meter 17 and a controllable drive 24.
  • the line ends in a chimney 23.
  • In front of the flow meter 17 there is a fresh air connection 19 with a fresh air line 18 and a fresh air flap 4, which can be regulated via a regulator drive 23.
  • shut-off flap 20 In front of the fresh air connection 19 there is also a shut-off flap 20, which can also be controlled via the regulator drive 23 or a separate drive.
  • a temperature sensor 21 is also provided for controlling the fresh air flap 4. If necessary, the temperature sensors 22 and 21 can be combined. The burner 3 or the fresh air damper 4 are then controlled by a controller or by the control technology.
  • a waste heat boiler 6 is connected to the line 13 for heat generation, the exhaust air subsequently escaping through a chimney 16.
  • a heat consumer 15 is also arranged on the waste heat boiler 6.
  • the smoke gas volume flow for the hot gas consumer 2 is set with the aid of the suction draft 1.
  • the hot gas can thus be coupled out immediately after the gas turbine 5 without pressure losses in the hot gas line, throttle valves being eliminated.
  • the hot gas is coupled out directly at a high temperature level in front of the waste heat boiler 6.
  • the furnace in front of the hot gas consumer 2 enables adjustment to the desired level. If a lower temperature is required, the temperature can also be lowered by controlled opening of the fresh air flap 4 by supplying cooling air. If the gas turbine 5 fails, the fresh air flap 4 is opened and the furnace generates what is known as ten "flying changes", ie without a drop in the hot gas temperature, the hot gas.
  • the butterfly valve 20 is then closed.
  • the flue gases are discharged through the boiler system without throttling the gas turbine 5 or bypassing the flue gases into the atmosphere via a bypass.
  • the heat generator is dimensioned such that the additional flue gas flow via the waste heat boiler 6 does not lead to an impermissibly high pressure loss via the flue gas path. This ensures that the gas turbine 5 does not have to be switched off or shut down.

Abstract

L'invention concerne un procédé pour produire simultanément de la chaleur et du gaz chaud par la production combinée d'électricité et de chaleur. Les gaz d'échappement d'une machine (9) sont séparés en un flux de gaz chaud (conduit de gaz chaud 14) sans clapet de régulation et en un flux de gaz de fumée supplémentaire (conduit 13 pour la production de chaleur) sans clapet de régulation pour la production de chaleur. Le flux de gaz chaud pour le consommateur de gaz chaud (2) est régulé au moyen d'un tirage par aspiration (1). Si le consommateur de gaz chaud (2) tombe en panne, la totalité des gaz de fumée est acheminée vers la chaudière (6) chauffée par la chaleur perdue, rendant ainsi une cheminée de dérivation superflue.
