Evaporation capacity: 1-35t/h, design pressure: 0.8-3.8MPa
Thermal oil furnaces have been widely used in industries such as textile printing and dyeing, chemical engineering, artificial leather, and building materials for more than 20 years. However, due to their high return oil temperature, generally between 200-250 ℃, the exhaust temperature of the boiler is also high, reaching 300-350 ℃ under normal circumstances, resulting in a large amount of heat being wasted and discharged into the atmosphere. In the current era of global energy scarcity and soaring energy prices, energy conservation has become a demand for sustained national development. Our company has long been committed to the comprehensive utilization of energy and can provide you with various low-temperature waste heat utilization solutions and projects. The phenomenon of short circuit caused by smoke.
