YY (Q) W type fuel gas heat transfer oil furnace

Organic heat carrier furnace is a new type of special boiler, also known as heat transfer oil furnace, with low pressure and high temperature working characteristics. 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 ℃. Organic heat carrier furnaces generally use coal, oil, and steam as fuels, heat transfer oil as the medium, and use hot oil circulation oil pumps to force the medium to circulate in the liquid phase. The heat 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.

1、 Structural principle of horizontal gas thermal oil furnace

The fuel (gas) heat transfer oil furnace uses oil (gas) as fuel and heat transfer oil as medium, and uses a hot oil circulation pump to force the medium to circulate in liquid phase. The heat energy is transported to the heating equipment and then returned to the heat transfer oil 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 thermal utilization rate, and due to the overall installation of modules, it is easy to operate and maintain. It is 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. When the boiler leaves the factory, the main body, oil storage tank, oil vapor separator, and filter should be installed. Circulating pumps, oil injection pumps, valves, instruments, electrical control cabinets, and other components are transported as a whole,
2. High level expansion tank, platform escalator packaged separately
3. Provide users with factory technical documents, product factory list, and installation instructions along with the furnace.
Equipment function:
⑴. Heating furnace:
The main body is the main part of the heating furnace system, from which the organic heat carrier obtains thermal energy.
⑵. Hot oil circulation pump: The hot oil circulation pump is the power source for the forced circulation of heat transfer oil in a closed circuit. Each heating furnace is required to be equipped with two pumps, one of which is a backup.
⑶. Expansion tank (high-level tank)
The expansion tank is used as a compensation for the volume change of heat transfer oil due to temperature changes, thereby stabilizing the pressure of the system heat carrier and helping the system dehydrate and exhaust steam. Therefore, the expansion tank should be set at a height 1.5-2M higher than other equipment or pipelines in the system. During normal operation, it should maintain a high liquid level state. When there is a sudden power outage or a malfunction of the hot oil circulation pump and an emergency shutdown is required, the cold oil replacement valve can be opened. At this time, the cold oil in the high-level tank can use its potential energy to flow through the furnace tube into the oil storage tank, thereby preventing overheating of the heat transfer oil in the furnace tube.
⑷. Oil storage tank (low-level tank)
The oil storage tank is mainly used to store the heat transfer oil discharged from high-level tanks, furnace tubes, and systems. It should be in a low liquid level state during operation and ready to receive external heat transfer oil at any time. The exhaust port should be connected to a safe area and no valves should be installed.
⑸. Oil injection pump (gear pump)
Used to replenish or extract heat transfer oil from the system. The direction of the arrow on the pump body is the direction of the main shaft rotation and also the direction of the medium flow.
⑹. Oil filter (Y-shaped oil filter)
The oil filter is used to filter and remove foreign objects in the heating system.
⑺. Oil vapor separator:
The oil vapor separator is used to separate and remove air, water vapor, and other gases from the heating system, ensuring stable operation of the heat transfer oil in a liquid phase without gas or water.
Burner: used to convert fuel into high-temperature flames.
