Special Axial-Flow Type Burner for The Asphalt Mixing Plant

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.

Technical characteristics

(1) Compliance with standards: in line with the international CE, DIN standards and GB national standard requirements, fully in line with the standard

(2) Oil control temperature ±1℃ : independent patent heater, small size, large power, corrosion resistance, long life. Achieve ±1℃ high control accuracy, to solve the impact of oil temperature fluctuations.

(3) 2% fine control of atomization gas volume: special structure adjustment valve, accurate regulation technology, so that the atomization gas volume is controlled at 2%, different loads are used under different atomization gas volume. The super load adjustment ratio of 1:10 can still ensure the flame stability under the large adjustment range.

(4) Oil precision control ±1% : real-time online monitoring of fuel volume changes, can display instantaneous, cumulative flow, single production fuel consumption, etc. The system automatically compensates the fuel amount to the target amount, and the deviation control reaches ±1% accuracy. Without flowmeters, it is impossible to save fuel!

(5) Air oil ratio adjustment: Based on the flow monitoring function, the air volume changes synchronously with the oil volume, so that the ratio of wind and oil in the combustion process is 100% accurate, and the possibility of ratio deviation is avoided.

(6) Self-judgment of oil pump wear rate: the system automatically determines the output capacity of the oil pump, while the combustion system automatically corrects the output capacity, which can extend the service life of the oil pump, and the combustion system will show the wear degree of the oil pump.

(7) Automatic alarm for oil pump replacement: When the oil pump is worn to the point that it cannot be used, the combustion system will issue a pump change alarm and prompt in advance, reserving enough time to prepare the pump head, and will not shut down to affect production.

(8) wear-resistant pump: high-end configuration wear-resistant pump, we promise to wear within 10 months, unconditional replacement (except for human factors), the service life is more than 16 times that of ordinary pumps.

(9) Pipeline electric heat tracing: All pipelines, pumps, valves are covered by electric tracing tropical, outsourcing insulation materials, 99.99 percent without dead corners. Even if the ambient temperature is lower than -10℃, it can also be stable and reliable combustion.

(10) High ignition success rate of heavy oil: The use of pipeline dredging, pre-heating, circulating oil and other technologies to achieve 100 percent success rate of direct ignition of heavy oil, without switching light oil ignition.

(11) Double oil valve: the national standard and the European label stipulate that the burner greater than 100kg/h should be set with "two series cut-off valves", and the double oil valve can solve the problem caused by leakage.

(12) Low nitrogen combustion technology: The use of advanced stratified combustion and air distribution technology, greatly reducing nitrogen oxide emissions, in line with environmental standards. Low nitrogen combustion, walking in the forefront of environmental protection technology!

(13) Remote diagnosis and processing: combustion engineers monitor the operating status remotely and in real time through the grid to guide quick troubleshooting. Without remote service, it is impossible to do "urgent customer"!

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.
