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 situations where uniform and stable heating is required and direct flame heating is not allowed, with process heating temperatures between 150°C and 380°C.
Fuel oil (gas) 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, making it 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 radiant heating surface. After passing through the rear of the inner coil, it rotates 180° forward into the interlayer area between the inner and middle tubes to form a convective 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, convenient adjustment, uniform heat supply, can meet precise process temperature.
(2) Liquid phase circulation heat supply, no condensation heat loss, high thermal efficiency of the heating system.
(3) The volume change of the working medium during heating and cooling is compensated by technical measures in the system.
(4) Before circulation heating, there are strict technical measures to 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 emergency 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.
