| titleOfInvention | Automatic Control of Bypass Valve of Blast Furnace Heat Exchanger |
| abstract | The present invention relates to a bypass valve automatic control method of a blast furnace hot stove heat exchanger.n n n The present invention is to measure the coke gas, blast furnace gas, combustion air, exhaust gas temperature, heat inlet flow rate and temperature supplied to the blast furnace to obtain the respective measured values and each measured value of the first step A second step of obtaining a gas heat transfer coefficient and a heat transfer coefficient on the basis of the second step; and an outer epidural heat transfer coefficient and an inner tube heat transfer coefficient using the respective measured values of the gas heat transfer coefficient, the heat transfer coefficient, and the first step. A third step, a fourth step of calculating a tube temperature by using the outer epidural heat transfer coefficient and an inner tube epidural heat transfer coefficient, a fifth step of calculating an acid dew point by measuring a sulfur oxide signal, and the tube temperature as measured values And a sixth step of inputting the acid dew point as a set value, and converting a valve output compensation value into a signal by using a combustion furnace replacement signal to prevent a temperature drop when the combustion furnace is replaced. It provides a bypass valve automatic control method of the blast furnace hot stove heat exchanger comprising a seventh step and an eighth step of operating the bypass valve in response to the signal of the seventh step. |
