Characteristics of gas thermal oil furnace

The YY (Q) W series fuel gas organic heat carrier furnace is a new type of special boiler, also known as a heat transfer oil furnace, which uses oil (gas) as fuel. It has low pressure and high temperature working characteristics, and its heating temperature can reach 340 ℃ in liquid phase or 400 ℃ in vapor phase. Organic heat carriers can be used for heating in various production scenarios where uniform and stable heating is required and direct flame heating is not allowed, with heating temperatures ranging from 150 ℃ to 380 ℃.
The gas thermal oil furnace uses gas as fuel and thermal oil as medium, and uses a hot oil circulation pump to force the medium to circulate in liquid phase. The thermal energy is transported to the heating equipment and then returned to the heating furnace for reheating. It has the ability to achieve high working temperature at low pressure and high-precision control of the medium operation. The system has a high heat utilization rate and is easy to operate and maintain, making it an ideal preferred heating equipment that is safe, efficient, and energy-saving. The fuel oil (gas) is ignited by the burner and generates a high-temperature flame, which enters the inner coil to form a radiant heating surface. It then rotates 180 ° forward through the rear of the inner coil and enters the interlayer area of the inner and outer tubes to form a convective heating surface. Then it enters the second interlayer area of the middle and outer coils at the upper part of the interlayer, and is discharged into the atmosphere through the chimney at the rear of the second interlayer area.

1. High efficiency
The horizontal triple pass structure balances the flame volume and heat exchange surface area of the burner to achieve the optimal temperature of the exhaust gas at the outlet of the smoke duct, and the thick insulation layer minimizes the heat dissipation of the boiler.
2. Security
Thickened heat-resistant steel pipes for boilers are the guarantee of boiler safety, and automatic ignition programs, automatic combustion control, automatic flame monitoring and alarm, over temperature and over pressure control and alarm make the boiler safer.
3. Long service life
A reasonable boiler structure, hot oil flow rate, and overall consistency of flow rate ensure that the furnace tubes will not burst due to carbon deposition, which not only ensures the safety of the boiler but also extends the service life of the oil.
4. One furnace with multiple temperatures
According to user requirements, a boiler can simultaneously output two or more heat transfer oils of different temperatures.
5. Pry assembly factory
According to the usage requirements of different occasions, install all devices together and pry them out of the factory.
6. Horizontal structure, easy to operate and use
Horizontal boiler, with a clean and elegant appearance, easy and simple operation.
7. Unmanned operation
The controller is centrally controlled, integrating automatic detection, control, and interlocking alarm prompts, and the boiler operation does not require on duty.

Product Introduction

1. Easy to install, as long as the upper body and lower combustion chamber are closed, the installation cycle is short.
2. The heating surface adopts closely arranged circular tubes, with sufficient arrangement to reduce the surface heat load of the tubes and make the use of heat transfer oil safer.
3. The medium flow is reasonable, and the thermal conductivity of the oil field is low (inlet) to (outlet). The gas generated during operation is better improved, which enhances the thermal efficiency of the boiler.
4. The fuel burns adiabatically in the combustion chamber, which makes the combustion easier and more complete, and improves the thermal efficiency of passing roads.
5. The top of the boiler is equipped with a dense arrangement of coils, which can better protect the top and prevent it from burning out.

Control System Description

This gas thermal oil furnace is controlled by an advanced program controller and can achieve various functions necessary for normal combustion. It can automatically implement protective alarms in normal, accident, and emergency situations, and is equipped with corresponding liquid level controllers, pressure controllers, and temperature controllers to achieve inlet and outlet pressure indication and inlet and outlet temperature indication, ensuring that the temperature of the heat carrier fluctuates within the normal range and the pressure is within the allowable pressure fluctuation range.
