The operating cost of a 15-ton oil-fired gas boiler includes water and electricity, fuel, sewage, and maintenance costs. Fuel costs are key expenditures and account for more than 80% of the operating costs. The operating efficiency of the oil and gas boilers launched by Zhengzhou Fangkuai Boiler Factory is generally above 98%. This data is among the best in the entire boiler market. It can be said to be very energy-saving, so the cost is also very low. Around 450 dollars.
Zhengzhou Fangkuai Boiler Factory would like to remind everyone here that during the operation of the boiler, the stability of the primary and secondary steam temperature must be controlled.
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 occurs, 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.
