Customized asphalt mixing plant heating and drying hot blast stove burner

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.

Burner product performance parameter table

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) Combined double valve: The certified SIEMENS double valve group is used to upgrade the product performance level to the level.

(3) Sensor leak detection: The use of imported high-reliability pressure sensors to avoid "trial and error" leak detection, valve leakage at a glance, to achieve "no leakage".

(4) Pressure regulation to save money: with pressure reduction and pressure regulation function to avoid the instability of flow caused by air source pressure fluctuations. No pressure regulation, no air saving!

(5) The higher the adjustment accuracy, the more saving: SIEMENS original gas regulating valve, high linearity of adjustment, adjustment accuracy of 0.2%. Without accurate adjustment ability, there is no talk of saving gas!

(6) Real-time flow monitoring: The flow meter is used to monitor the change of gas volume in real time, which can display instantaneous, cumulative gas flow, single production gas consumption, etc.

(7) Gas volume control accuracy ±1% : According to the flow measurement signal, the system automatically compensates the gas volume to the target amount, and the deviation control reaches ±1% accuracy. Without flowmeters, it is impossible to save gas!

(8) Low nitrogen combustion technology: the use of advanced stratified combustion technology, greatly reduce nitrogen oxide emissions, in line with environmental standards. Low nitrogen combustion, walking in the forefront of environmental protection technology!

(9) 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.

About US

Quanzhou Faer Machinery Technology Co., Ltd. engaged in boiler, kiln, construction machinery combustion industry for nearly 30 years, asphalt mixing and dry powder combustion equipment supporting up to 17 years, is a technology is good at science and technology enterprises.

The company with Europe has the world's leading combustion technology platform developed low nitrogen, intelligent burner, because of its excellent quality, perfect after-sales service system, attracted a large number of stable customer base.

In order to better serve the market, the company and a number of domestic dealers together to form a stable sales, commissioning, maintenance and spare parts service network, more convenient, fast, improve product services.

In response to the Chinese government's call for energy conservation and emission reduction, the company has developed new AGB (gas), AOB (fuel), ADB (oil and gas dual use) series of low NOx burners, which have served a number of sets of asphalt mixing equipment.

AGB, AOB, ADB burner using the world's advanced combustion technology, with reference to EN676 and relevant standards at home and abroad designed and manufactured new electromechanical integration automatic burner, widely used in steam boilers, hot water boilers, thermal oil furnace, cement kiln, asphalt mixing station, air heating furnace and other industrial kilns. The use of fractional combustion and fuel reburning technology prevents high oxidation in the flame, thus reducing the emission of pollutants.

The burner is made of Siemens PLC and fully digital adaptive synchronous proportional regulation system to ensure that the burner maintains a high level of combustion efficiency and adjustment accuracy, thereby reducing fuel consumption and saving user operating costs.

In 2018, FARr burners obtained the authorization certificate of the British FARRBURNER brand, successively passed the relevant certifications of European and Russian burners, obtained the European CE and Russian EAC certificates, and obtained the national high-tech enterprise.

Farr burners directly and indirectly exported to Russia, Europe, Africa, Southeast Asia and other regions, is a good reputation.
