The 4-ton gas-fired hot water boiler is a small boiler, which can output 4 tons of high-temperature hot water per hour, and is often used in the heating and heating field. Many users are very interested in the operating efficiency of this type of boiler. After all, the operating efficiency is related to the operating cost of the boiler. Zhengzhou Fangkuai Boiler Factory is here to tell you how much the operating efficiency of a 4-ton gas-fired hot water boiler can reach.
The 4-ton gas-fired hot water boiler launched by Zhengzhou Fangkuai Boiler Factory creatively incorporates condensing, full premixing, FGR and other combustion technologies. It can not only control nitrogen oxide emissions to 30 mg, but also have an operating efficiency of more than 104%. It occupies a leading position in the entire market and has also received many users' love.
Controlling the stable primary and secondary steam temperature during boiler operation is extremely important for the safe and economic operation of the unit. When the steam temperature is too high, the strength of some metals such as superheaters, reheaters, steam pipes, steam turbine cylinders, and rotors will be reduced, which will shorten the service life of the equipment. When the temperature is severely overheated, the heating surface tube will burst. If the steam temperature is too low, the efficiency of the thermal cycle will be affected, and the steam humidity at the non-stage blades of the steam turbine will be too high. In severe cases, water hammer may occur, causing blade breakage and damage. If the steam temperature rises and drops by a large margin, in addition to generating greater thermal stress on the welding joints and connecting parts of the heating surface of the boiler, it will also cause the relative displacement between the cylinder and the rotor of the steam turbine to increase, that is, the expansion difference will increase. Even dynamic and static friction between the impeller and the baffle may occur, causing severe vibration. In addition, the excessive deviation of the steam temperature on both sides of the steam turbine will cause uneven heating and uneven thermal expansion on both sides of the steam turbine. Therefore, the steam temperature should be closely monitored, analyzed, and adjusted during the operation of the boiler, and the most reasonable method should be used to control the stability of the steam temperature.
