Product Introduction：The gas fired thermal oil boiler uses gas as fuel and thermal oil as the heat-conducting carrier, and can be used as a high-temperature heat source under various environments below 350°C. It is widely used in various industries that require high-temperature heating or drying.

Description of Boiler

This boilers product has the advantages of high temperature, low pressure, precise temperature control, and high heat utilization rate. The thermal oil boiler can also be equipped with a steam generator to produce saturated steam below 1.3MPa for users to use.

The gas-fired thermal oil boiler is a new type of YY(Q)W series thermal oil furnace developed by our company. It is carefully developed by our company based on years of design and manufacturing experience, combined with European advanced technology, and absorbing the advanced successful experience of domestic and foreign counterparts. The thermal oil furnace and system produced by our company adopt advanced structural types, from low-end manufacturing to high-end intelligent manufacturing and creation of intelligent high-end products.

It is equipped with original imported burners and PLC fully automated intelligent control systems, which are safe and reliable in operation. Low noise, no pollution, high efficiency and energy saving, easy installation and operation. All technical indicators meet or exceed national standards, creating a series of integrated, modular, and intelligent high-end products, which are environmentally recommended products.

Technical Advantages

1. Possess an extra-thick insulation layer to minimize heat loss;
2. The thickened boiler heat-resistant steel pipe is the guarantee of boiler safety, advanced technology and procedures ensure the safety and stability of the boiler, automatic flame alarm device, automatic control of the pressure and temperature of the boiler;
3. The reasonable boiler structure, the overall consistency of the hot oil flow rate and the flow rate ensure that the furnace tube will not burst due to carbon formation, which not only ensures the safety of the boiler, but also extends the service life of the oil;
4. According to user requirements, a boiler can simultaneously output heat transfer oil of different temperatures to heat the heated body;
5. According to the user’s requirements in different occasions, install all the equipment together, skid-mounted and leave the factory;
6. Horizontal boiler, neat and generous appearance, convenient and simple operation;
7. The controller is centrally controlled, integrating automatic detection, control, and interlocking alarm prompts. The boiler operation does not need to be on duty;
8. The horizontal three-pass structure is all back-type structure, which is equivalent to the four-pass structure with the addition of an energy saver. Higher thermal efficiency;
9. The boiler has a large water capacity and a large steam holding capacity, which reduces the frequent start and stop of the boiler and prolongs the service life of the burner and electronic components;
10. Fire tube structure, no tube burst phenomenon, safer to use;
11. Both the front and rear smoke boxes can be opened, making the boiler maintenance very convenient.

Main Technical Applications

1. Adopting wet-back internal combustion two-pass structure, with a top coil on the top of the boiler, which effectively prevents the flame from directly radiating the back wall. At the same time, under the premise of a compact structure, it increases the radiant heating area and improves the thermal efficiency of the boiler.
2. The use of micro-positive pressure operation effectively improves the combustion intensity of the furnace, makes the boiler of the same capacity smaller, and eliminates air leakage in the furnace and flue of the boiler, and improves the thermal efficiency of the boiler.
3. Adopt advanced EDA technology, calculate the size of the furnace body, the flow rate of the flue gas in detail, make full use of the flame and flue gas heat exchange, ensure the reliable operation and full cooling of the boiler, and improve the thermal efficiency of the boiler.
4. The use of high-efficiency condensing technology effectively reduces the temperature of the exhaust gas and improves the thermal efficiency of the boiler.
5. Using reasonable structural design and excellent refractory and thermal insulation materials, the surface temperature of the furnace is greatly reduced, so that the surface temperature is lower than 50° (higher than the national standard), reducing heat loss, and improving the thermal efficiency of the boiler.
6. Adopt a new design to reduce the emission of harmful substances when fuel is burned, meet the national environmental protection standards, especially reduce the emission of nitrogen oxides, and meet the national low-nitrogen emission standards.
7. Imported burners of many internationally renowned brands are used to adapt to various application scenarios to ensure quality and safety.
8. Using PLC and other automation controllers of major international brands such as Siemens as the control core, and also using peripheral components of major international brands to achieve a high-quality automatic control system, which can collect import and export temperature, pressure, etc. The parameters are displayed centrally in the control cabinet in real time, and the closed-loop control system such as PID ensures that the boiler works stably under various parameters set by the user, while monitoring the working range of the data, and reminding or alarming various abnormalities, which is convenient for users Use and maintenance. The control module also has powerful expansion capabilities, which can easily realize multiple in-depth applications such as group control and remote control according to customer needs.
