Energy saving and environmentally friendly asphalt mixing plant combustion oil and gas dual-use combustion equipment

Performance characteristics of the burner

Farr burners are designed with CFD combustion simulation technology, which uses the powerful computing function of the computer combined with computational fluid dynamics to simulate the operation of the burner and the furnace body (including the temperature field, flow field, flame shape, combustion products, aggregate temperature, etc.). At the same time, the effect of fuel and air distribution on complete combustion can be simulated in a virtual environment according to the actual drum geometry.

1, the burner adopts the axial flow fan integrated layout, convenient installation.

2, the combustion head of the burner is made of high temperature resistant stainless steel material, and the unique combustion head structure design realizes the hierarchical combustion of air and gas (fuel); The high-speed gas flow forms a local flue gas circulation at the outlet of the flame tube, reduces the flame temperature, greatly reduces the emission of NOX, and realizes efficient combustion.

3, the burner has an automatic monitoring system for fuel flow or gas flow, which can monitor the flow change in real time, and the frequency of the combustion fan is adjusted to achieve the wind-oil ratio can be automatically matched and followed under any working condition, without manual modification of the ratio parameter. This function can greatly reduce the user's fuel consumption and gas consumption, without flow monitoring, can not really achieve energy saving.

4, unique oil pump wear warning function, can be in the case of wear or corrosion of the oil pump, performance decline, automatically determine whether the performance of the oil pump has a surplus, if the surplus is insufficient in advance alarm prompts the need to replace the pump, reserve about 7-10 days to prepare the oil pump, so as not to affect the construction period.

5, the unique fuel atomization pressure regulation technology can ensure that the best combustion requirements are met under various working conditions from small fire to large fire, to meet the 1:5 super adjustment range, to achieve accurate combustion and avoid waste of fuel.

6. Burner control system includes: Gas valve group seal automatic detection, before (after) purging, automatic ignition and program start and stop, flaring protection, low pressure protection, safety interlock protection and combustion, load regulation, automatic fuel monitoring, fuel pump wear warning, electric heater automatic temperature control, aggregate automatic temperature control, low atomization pressure, high fuel temperature, low fuel temperature, oil pump overpressure protection, low fan current

7, the main control components of the burner are used in the industry of international well-known brands to ensure the safe and efficient operation of the burner.

8, ADB burner (DP version) adopts the two-level UNIWO air valve imported from the UK in line with safety specifications, with low failure rate, long life and good sealing. Equipped with original SIEMENS gas regulating valve, adjustment accuracy up to 0.2%, reduce gas consumption, no need to support the gas filter (easy to clog, resulting in high failure rate of the valve group).

9, ADB burner built-in digital electronic proportional adjustment system and parameter screen display, to achieve human-machine dialogue.

Burner installation precautions

For the installation of the combustion system, the following aspects should be paid attention to:

1. Installation of burner body. According to the actual situation of the site, combined with the overall size of the burner, determine the direction arrangement of the drum, gas pipeline and air duct (split machine). The interface flange of the burner and the roller needs to be made by the customer on site.

2. Installation of valve group. The gas valve group of the AGB gas burner does not have the function of pressure regulation and pressure regulation, so the user needs to do a good job of pressure regulation and pressure reduction at the front end of the gas supply, and the valve group does not have a filter, so the front end pipeline should be fully purged before the use of the new pipeline to avoid a lot of debris into the valve group.

3. Installation of control cabinet. In strict accordance with the construction of the circuit diagram, the control cabinet is equipped with a remote connection module. When the system is not working normally, or when a remote engineer is needed to assist in debugging or fault diagnosis, the Internet can be connected through the mobile phone WIFI sharing, and the remote engineer can connect to diagnose the fault, which can greatly shorten the time of sending personnel to solve the on-site fault.

4. Installation of fuel pump group. The fuel pump group should be set within 3 meters of the tank outlet (too long a distance may lead to oil supply failure), and the diameter of the pipe before the pump group should be DN50, and the diameter should be changed to DN40 before the pump group. All the return pipelines are DN25, which can be directly returned to the upper liquid level of the oil tank. No other valve can be set on the return pipeline to prevent overpressure burst caused by misoperation of the valve.

About FARRBURNER

In 2018, Quanzhou Farr Machinery Technology Co., Ltd was authorized by United Kingdom to develop, produce and sell United Kingdom FARRBURNER brand burner products.

The products have successively obtained the EU CE certification and the Russia EAC certification, and won the title of national high-tech enterprise.

The products have been sold to the European Union, Russia, Southeast Asia, Africa and other regions to achieve remote guidance installation and commissioning, remote training.

FARRBURNER burners are installed in places where the ambient temperature is -32 ° C in Russia, and also in the highlands of Africa at an altitude of 4000 meters, and some near the equator where the air humidity reaches 100% at 50 ° C in Southeast Asia, it can burn normally for a long time under environmental conditions of minus 5 ° C, and can also work under conditions of 50 ° C, or even higher temperatures (customization required), without being affected.

FARRBURNER burners are praised and recognized by customers for their consistent and reliable performance, low failure rate, and excellent quality.
