Advantages of heat transfer oil heater for plywood hot press

At present, energy conservation and environmental protection are advocated, and boiler transformation is carried out. The steam heating and boiler heating methods commonly used in plywood hot press heaters are gradually eliminated. A new type of heat transfer oil electric heater used for heating plywood hot press began to highlight its advantages.

Plywood hot press heat transfer oil electric heater

、 The heat transfer oil electric heater has high thermal efficiency and saves more energy. As we all know, the steam will release heat when it reaches the hot pressing plate and condenses into water. At this time, if the hot water can be recovered, it can reduce the loss of some heat. If it can not be recovered completely, the heat carried by these hot water will be completely wasted. According to statistics, about 20% of steam heating heat is wasted. In the heat transfer oil electric heater, the heat transfer oil circulates and heats up without unnecessary heat loss. The heat efficiency of the heat transfer oil electric heater can reach 90%, which saves more energy. The heating of the plywood hot press is achieved by heating the heat transfer oil through the heat pipe of the heat transfer oil electric heater. Unlike steam heating, it requires constant exhaust to heat, resulting in a large amount of heat waste.

2、 The electric heat transfer oil heater has high safety, uniform temperature, and temperature difference between plus and minus 1 ℃. In order to meet the heating needs of the plywood hot press, the boiler pressure should be above 13 kg, while the electric heat transfer oil heater generally only needs 3-4 kg pressure to heat the temperature to 350 ℃. Since the temperature of steam depends on the pressure, there is a difference in pressure and temperature when there is a difference in position. The steam-heated plywood hot press is prone to temperature difference and uneven heating, which affects the quality of plywood. The heat transfer oil used by the electric heater with good heat transfer performance has a uniform and stable temperature without temperature difference.

3、 Improve production efficiency and reduce enterprise costs

Compared with boiler heating, the heat transfer oil electric heater is easy to operate. Automatic temperature control can heat the press in advance and stabilize the temperature of the press. Because there are many potential safety hazards in the boiler, annual inspection is also required, special boiler rooms are set up and special personnel are assigned to operate, which also increases the cost of the enterprise. Due to the uniform temperature and good stability of the heat transfer oil electric heater, it also plays a great role in improving the product quality. Under the current situation of market economy, the plywood industry is actively trying to reduce production costs and improve product quality. It has been proved to be an effective way to transform the steam-heated press into a heat-conducting oil electric heater.
