Gas-fired thermal oil heater is a new type of special boiler with low pressure and high temperature working characteristics. Its heating temperature can reach 340°C in liquid phase or 400°C in vapor phase. Organic heat carrier heating can be used in various production occasions that require uniform and stable heating and do not allow direct flame heating, with process heating temperatures between 150°C and 380°C.
Oil (gas) fired organic heat carrier boiler uses oil (gas) as fuel and thermal oil as medium. It uses a hot oil circulation pump to force the medium for liquid phase circulation, transferring heat energy to the heat-using equipment and then returning to the heating furnace for reheating. It can obtain high working temperature under low pressure and perform high-precision control of medium operation. The system has high thermal efficiency. Due to modular overall installation, it is easy to operate and maintain. It is a safe, efficient, and energy-saving ideal heating equipment. The fuel oil (gas) is ignited by the burner to produce a high-temperature flame that enters the inner coil to form a radiation heating surface. After passing through the rear part of the inner coil, it rotates 180° forward and enters the interlayer area between the inner and middle tubes to form a convection heating surface. Then, at the upper part of the interlayer, it enters the second interlayer area between the middle and outer coils, and from the rear of the second interlayer area, it is discharged into the atmosphere through the chimney.
Performance Features:
(1) Obtain low-pressure high-temperature heat medium, easy to adjust, uniform heat supply, can meet precise process temperature.
(2) Liquid phase circulation heat supply, no condensation discharge heat loss, high thermal efficiency of the heat supply system.
(3) The volume change of the working medium during heating, heat release, and temperature rise and fall is compensated by technical measures in the system.
(4) Before circulating heat supply, there are technical measures to strictly control the content of air, moisture, and other low-volatile substances in the working medium.
Control System Description:
This gas-fired thermal oil heater is controlled by an advanced program controller, which can realize various functions necessary for normal combustion. It can automatically implement protective alarms under normal, accident, and abnormal conditions. Equipped with corresponding liquid level controller, pressure controller, and temperature controller, it achieves inlet and outlet pressure indication, inlet and outlet temperature indication, ensuring that the heat carrier temperature fluctuates within the normal range and the pressure is within the allowable pressure fluctuation range.
