1. Advanced technology: the natural gas regenerative forging furnace adopts the current advanced "pulse regenerative combustion", which is based on the continuous development and improvement of the integral regenerative combustion mode of the conventional regenerative burner products; The working principle of the regenerative combustion: the regenerative burner works in pairs, the two alternately change combustion and smoke exhaust, and the regenerator in the burner changes heat release and endothermic state correspondingly. The paired burners are arranged at position A and position B on both sides of the furnace wall. When the position A burners burn, the air flows through the heat storage body which has accumulated heat and is heated to about 50 ℃ ~ 150 ℃ below the furnace temperature to participate in the combustion. At the same time, the position B burners exhaust smoke. The flue gas heat is absorbed by the regenerator and the exhaust temperature is reduced to about 50 ℃ ~ 100 ℃. After the change of direction, the B position burner is burned, and the air is similarly heated by the regenerator to a temperature about 50 ℃ ~ 150 ℃ below the furnace chamber temperature to participate in the combustion, and the A position burner exhausts the smoke. The flue gas heat is absorbed by the regenerator and the exhaust gas temperature is reduced to about 50 ℃ ~ 100 ℃. In this cycle, the residual heat of the flue gas from the regenerator is converted into the physical heat of the air, and the waste heat is recycled. The regenerator with sufficient heat transfer ability and heat capacity can fully recover the residual heat of flue gas and preheat the air to a very high temperature. Through the regenerative burner, the flue gas discharge temperature can be reduced to 50,100 ℃, the air can be preheated to a high temperature below 50 ℃ ~ 150 ℃ below the furnace chamber temperature, and the heat recovery efficiency can reach more than 85%. This can not only save a lot of energy, but also greatly increase the theoretical combustion temperature of fuel, reduce the rate of heat loss, and increase the output. Therefore, regenerative combustion system is widely used in various industrial furnaces and kilns.
High thermal efficiency and low energy consumption of natural gas forging furnace.
The main results are as follows: 1. Integral regenerative combustion adopts lower part of both sides wall, good heat preservation and low energy consumption.
2. Through the scientific calculation of PLC, the natural gas forging furnace realizes the proportional linkage of gas, air and flue gas, realizes the complete combustion of gas, and has the ideal energy-saving effect.
III. Reducing environmental pollution.
1. Pulse regenerative combustion is adopted to realize the dispersive combustion mode, which greatly reduces the emission of NOX.
2. As a result of the adoption of regenerative combustion, the exhaust gas temperature is greatly reduced, and the temperature at which the air enters is lower than 100 ℃.
3. Due to the complete combustion of natural gas, the emission of CO is greatly reduced, which is superior to the environmental protection emission standard.
The high reliability and security of the equipment: the equipment must first be designed from the hardware and software must ensure the reliability and security of the system, in addition, but also to consider the abnormal circumstances of the emergency plan.
1. The valve on the gas pipeline adopts import brand.
2. The fans adopt domestic brand products.
3.The low voltage electrical apparatus adopts Schneider products.
4. The stability of PLC system software is high.
5. The system is equipped with power-off protection, gas-off protection, ignition protection, over-load protection, under-voltage protection, over-temperature and pressure protection, and has the function of alarm diagnosis, which greatly improves the safety performance of the system.
High performance-price ratio: adopt the principle of seeking truth from facts in the equipment price accounting, not only to ensure the high-tech performance and reliability of the equipment, but also to reduce the equipment profit, make a suitable scientific quotation, and achieve the purpose of win-win.
