- the temperature distribution in the furnace measured by the in-furnace temperature measuring device, or the mixture that is blown into the pre-chamber from each nozzle installed in the pre-chamber according to the control temperature The amount of gas (empty low-temperature gas) is controlled by controlling the ratio of each air injection amount and low-temperature gas injection, so that the temperature variation inside the pre-chamber can be made uniform. Since local excessive temperature rise can be controlled, the problem of brick damage and adhesion of molten ash can be solved, and stable operation of the cokes dry fire extinguishing system has become possible. In addition, because it uses its own circulating gas instead of water or steam, there is no extra running cost in the pre-chamber. The temperature distribution could be improved. Industrial applicability
- the present invention it is possible to make the temperature variation inside the pre-chamber one uniform, and it is possible to suppress a local excessive temperature rise, so that there is a problem of brick damage and adhesion of molten ash. It became possible to solve this.
- the amount of gas blown into the furnace from each of the multiple nozzles provided in the pre-chamber the amount of gas flowing in the circumferential direction of the furnace is constant, so that it is stable.
- the dry dry fire extinguishing equipment can now be operated.
- because water or steam is not used, brick spalling is prevented from being damaged, and since self-circulated gas is used instead of water or steam, pre-chamber is not generated without generating extra running costs. It has extremely excellent effects such as the ability to improve the temperature distribution within the chamber.
