How to save energy in high temperature trolley furnace

You may not know that the high-temperature trolley furnace is more likely to be a waste of energy when it is used. Therefore, it is necessary to choose the correct energy-saving use to improve its efficiency.

Temperature control is mainly to control the opening frequency of the combustion-supporting air electric position control valve. When the temperature control instrument outputs a signal to the electric position control valve on the combustion air pipeline, the valve opens to the high air position, and the high-temperature trolley furnace passes through the combustion air pipeline and The hot air pressure pipe between the gas pipelines makes the proportional valve on the gas pipeline open to the corresponding high fire position, and the two form a large flame.

The thermal efficiency can also be improved by accurately controlling the furnace pressure of the high-temperature trolley furnace. The furnace pressure control has a great influence on the gas consumption of the gas furnace. If the furnace pressure is too high, a large amount of flue gas overflows in the furnace, which takes away a large amount of heat, which forms a waste of heat energy and reduces the life of the smoke exhaust device. If the furnace pressure is too low, a negative pressure is formed in the furnace, and a large amount of cold air enters the furnace to reduce the temperature in the furnace, resulting in a waste of repeated heating energy.

Theoretically speaking, it is good for the furnace pressure of the high-temperature trolley furnace to be maintained at ±0Pa, but it cannot be achieved in practice. The furnace pressure can be accurately controlled within ±10 Pa through adjustment. The flow of the flue gas exhaust system with stable furnace pressure is stable and uniform, the temperature of the preheated combustion air is uniform, and the flame burns uniformly without fluctuation, and there is no heat wave impact in the furnace of the high-temperature trolley furnace to achieve uniform combustion and save energy.
