According to the current environmental protection policy of China，Heavy oil due to strong taste，Strong harm to human body and environment，It does not meet the current environmental protection requirements.，Most of the production sites have used natural gas as the fuel of the mixing station.。The old mixing plant wants to meet environmental standards for production.，Use environmentally friendly fuels，The burner should be modified first.。

 

Transformation of Heavy Oil Burner into Oil and Gas Burner

Maleny is used domestically.CBSVendor-supplied standardized retrofit components，The oil burner can be easily converted into an oil-gas dual-purpose burner by means of bolting.，And has no effect on the performance of the existing equipment.。Reformed oil-gas dual-purpose burner，The fuel will be mainly natural gas.，Heavy（Light）Oil as a supplement。In use，It is very easy to switch between the two fuels。

CBSNatural gas provided by the manufacturer、Heavy oil（Light oil）The dual-purpose burner has been made by Marini.（China）Successfully applied in the domestic market，The response was good，Economy in use、Failure rate and environmental protection data，It has more obvious advantages than heavy oil burners.。

Advantages after transformation

Environmental protection advantages

Green mountains and clear waters are mountains of gold and silver.， With the strengthening of domestic environmental protection policies,，The supervision of environmental protection departments around the country will become more and more stringent.。Natural gas as a high quality、Clean、Efficient Green Energy，As a fuel, it can not only respond to the call of the state, but also meet the production requirements.，It is bound to become the development trend in the next few years.。

And that service life of the equipment is prolon

Due to the clean nature of natural gas,，During use of the burner，The damage to the dust bag is very small，And that service life of equipment can be effectively prolon.。

Reduce workload

Due to the uneven quality of domestic heavy oil,，In the process of production，It is easy to fail to catch fire.，Causing the filter screen to be clogged、Too many impurities and the like.，Frequent cleaning of the strainer by field staff is required，Remove the booster pump and pipelines，And dispose of that burner gun，It greatly increases the workload.。

Save money

From the perspective of later maintenance and use， The follow-up advantages of natural gas are obvious.。In the later period of using natural gas, there is almost no replacement of the wearing parts of the burner.，While heavy oil is used，Replacement of the booster pump will be involved、Repair，Replacement of accessories for burner gun，Even the replacement of guns and primary pumps, etc.，The use of the above consumables depends entirely on the quality of the heavy oil，This cost accounts for a large part of the total equipment maintenance。

Examples of modifications

To apply to Maleny.MAC 320/MAC 360 (Model 4000/Model 4500)Mixing plant 24MW CBSTake the burner as an example， ForMAC320 SelectedCBSThe main technical parameters of the natural gas burner are as follow：

Burner power：24MW

Working pressure of natural gas：300 – 400 mbar

Maximum gas consumption of natural gas：2400 m3/H

Burner interface flange：DN150

ForMAC60 of 320 – 100 – Choice of 1.3 million kcal heat transfer oil furnaceRIELLOThe main technical parameters of the natural gas burner are as follow：

Burner power：814 – 1163 – 1395 KW

Working pressure of natural gas：50 mbar

Maximum gas consumption of natural gas：80 – 120 – 160 m3/H

The modified oil-gas dual-purpose burner is provided with a stop valve.、Filter、Gas pressure regulating device、Double-valve assembly and safety leakage detection device。In addition to the above configuration，The gas supply pipeline and other connecting accessories shall be negotiated by the user and the gas supplier。Laying of air supply pipeline to the combustion gas interface，Requires use of soft connection（Expansion joint）In communication with the burner。

Maleny for different types of brands of asphalt mixing plant，Provide a full range of environmental upgrading services。According to the specific needs of customers， Reasonably designed reconstruction scheme，The pollutant discharge of the existing asphalt mixing plant in the production process is minimized.。
