During the practical operation of gas-fired boilers, the heating condition will change from time to time. When the weather changes, the total heat demand in the heating zone of the boilers will change accordingly. Shandong Gas Boiler reminds you that there are also differences in the heat demand situation between day and night in a day, which requires gas boilers to stop scientific and reasonable adjustment of the gas and air deliveries according to the change of total heat demand in time, so as to ensure the operation efficiency of the boilers, not only to ensure the necessary heat demand supply, but also not to.
Waste gas resources. At present, there are many low nitrogen extinguishers with electronic proportional conditioning. For this kind of extinguisher, the outlet temperature is controlled by single-loop PID. On this basis, according to the difference between the set value of outlet temperature and the measured value of outlet temperature, the fuel valve is adjusted to make it reach a reasonable state gradually. In this process, in order to achieve the best extinguishing effect, it can also directly increase the oxygen content of flue gas, thus ensuring sufficient oxygen in the air.
Generally speaking, extinguishing control algorithm has certain manual guidance function. In detail, it can set the operation time of the boiler by manual self-determination. From the ignition of the boiler to its full load operation, different types of boilers require different time. When the boiler is running under load, the internal quenching control software will stop adjusting the boiler according to the change of the practical temperature. If the temperature difference is large, usually the boiler will use full-open extinguishing, dynamic adjustment of intelligent software, so that the full-load boiler can run smoothly, in order to reduce fuel wastage.
