What are the two energy-saving and emission reduction methods for trolley annealing furnaces in the workshop

The trolley annealing furnaces in the workshop need to be produced and used for a long time, which consumes a considerable amount of energy. In China, environmental protection is increasingly emphasized. Enterprises should actively respond to the national energy-saving and emission reduction policies, reduce unnecessary resource waste, choose and use the correct energy-saving methods, and improve production efficiency.
1, In terms of fuel control
Temperature control is mainly used to control the opening frequency of the electric position regulating valve for combustion air. When the temperature control instrument outputs a signal to the electric position regulating valve on the combustion air pipeline, the valve opens to the high wind position. Through the hot air pressure pipe between the combustion air pipeline and the gas pipeline, the proportional valve on the gas pipeline is opened to the corresponding high fire position, forming a large flame. In conventional design, a small fire pipeline is also required. Here, we make adjustments to the original pipeline to form a small fire pipeline. When the electric position control valve is in the closed position, there is a 5 "angle between the valve plate and the valve body. Even if the trolley furnace valve is in the closed position, there is still a certain amount of combustion air passing through, and this combustion air flow rate is called the combustion air constant.
The thermal efficiency can be improved by controlling the furnace pressure of the trolley furnace. The control of furnace pressure has a significant impact on the gas consumption of gas boilers. If the furnace pressure is too high, a large amount of smoke will overflow from the furnace, taking away a large amount of heat, resulting in heat energy waste and reducing the service life of the smoke exhaust device; If the furnace pressure is too low, negative pressure is formed inside the furnace, and a large amount of cold air enters the furnace to reduce the temperature inside, resulting in repeated heating energy waste. In theory, it is good to maintain the furnace pressure of the trolley furnace at ± 0pa, but it cannot be achieved in practice. By adjusting, the furnace pressure can be accurately controlled within ± 10 Pa. The flow rate of the furnace pressure stable smoke exhaust system is stable and uniform, and the temperature of the preheated combustion air is uniform. The flame burns uniformly without fluctuations, and there is no heat wave impact in the furnace to achieve uniform combustion, saving energy.
