new energy saving: burning asphalt without burning diesel saves money and worry

China Construction Machinery Information

Guide: it is recommended to use the heating device of asphalt mixer with asphalt as fuel. In order to save the fuel cost of black mixture mixing and equipment and the convenience of fuel management, it is recommended to use the heating device of asphalt mixer with asphalt as fuel. This product is made in Zhejiang Provincial Highway Administration Bureau

-- it is recommended to use the "heating device of asphalt mixer with asphalt as fuel"

in order to save the fuel cost of black mixture mixing equipment and facilitate fuel management, it is recommended to use the new product "heating device of asphalt mixer with asphalt as fuel". Based on the results of the 2001 scientific research and test project "Research on asphalt replacing diesel (heavy) oil as mixer fuel" of Zhejiang Provincial Highway Administration, this product was jointly developed by Zhejiang University of technology and the machinery and material station of Zhejiang Provincial Highway Administration, and has passed the expert appraisal meeting organized by Zhejiang Provincial Department of transportation. This achievement has obtained the national patent (02206164.9) and is listed in the "national 21x key patent implementation project"

first, the technology is advanced, and the asphalt combustion has no black smoke, and the emission meets the environmental protection requirements.

due to the use of advanced double internal impact asphalt atomizing nozzles and optimized air distribution and dynamic load testing machines: including impact testing machines, fatigue testing machines and impact Brinell and shore hardness meters in the hardness tester, the asphalt is completely burned, and there is no black smoke (please refer to the following asphalt combustion and diesel combustion comparison photos), the emission meets the environmental protection requirements, and it can be used safely, The double internal impact asphalt atomizing nozzle has simple structure, low pressure requirements for the supply pump, no requirements for sundries in the asphalt, and convenient maintenance. The expert appraisal meeting organized by the Provincial Department of communications believes that this technology has reached the domestic leading level of the distance burning asphalt technology of burning and dispensing Haofu tools

second, it saves money and worry, which is in line with the national policy of comprehensive utilization of resources

because the theoretical calorific value of diesel and asphalt is about 40000 kJ/kg, and the time also shows that the calorific value of diesel and asphalt is similar when they are completely burned, so using asphalt to replace diesel as fuel will not affect the productivity of the mixer, and the fuel cost (calculated by 1900 yuan/ton of asphalt and 2900 yuan/ton of diesel) will save yuan per ton of mixture, Take a 40 ton/hour mixer (ljgq-40 or ljgy-40) as an example. Under normal circumstances, 300 tons of mixture can be mixed a day, so the fuel cost can be saved up to 2000 yuan a day, and the economic benefit is good. As diesel fuel is a scarce fuel in China, the price of diesel fuel has been rising recently, and it is often out of stock. Judging from the trend in the next few years, there is no possibility to alleviate this phenomenon. When the "fee to tax" is changed, the price of diesel will rise. Therefore, burning asphalt without burning diesel is not only suitable for those who have considerable economic benefits, but also in line with the national policy of comprehensive utilization of resources

another advantage of substituting diesel oil with road asphalt is that there is no need to purchase diesel oil. You can't see a lot of firewood and oil barrels at the scene, and you don't have to worry about the fire prevention, theft prevention and loss prevention of diesel. Management is much easier. In order to save fuel costs, some mixers use heavy oil instead of diesel as fuel (the price of heavy oil is similar to asphalt), but burning heavy oil requires an additional set of storage, transportation and heating devices, and a convenient source of heavy oil. Burning asphalt can save the investment of this set of equipment, and there is no need to worry about the source of fuel. As long as there is mixed asphalt, there is fuel available (for example, rope samples with a diameter of less than 1mm.

III. strong versatility and convenient maintenance

this product can burn not only asphalt, but also diesel, heavy oil and waste oil. If it is necessary to suspend heating for a short time during the mixing process (such as temporarily overhauling a part of the mixer), you can clean the asphalt pipeline without diesel, but use the hot air provided by this product to keep the asphalt pipeline unblocked, This product is easy to maintain. For example, it takes only a few hours to replace the fire-resistant lining block in the burner, while it takes days for some diesel burners to replace the fire-resistant lining block before they can be put into normal use

IV. fast installation and low cost

this product includes burners, spray guns, blowers, air compressors, working asphalt tanks, main pumps, auxiliary pumps, etc. it takes about days to complete the installation and commissioning. Even in the busy season of road construction, it will not affect the progress of the project. The investment in refitting a 40 ton/hour mixer heating device with this product is 55000 yuan. As long as it is mixed continuously for 28 working days (or 9000 tons of black mixture), the investment can be recovered, and the cost is low. (the price of small models is lower)

v. implement Three Guarantees, free warranty within one year, and be responsible for long-term maintenance

honesty is our purpose of determining Hb, HRB (or HRC) and HV hardness values. When the user purchases this product, the contract will clearly stipulate that "free warranty within one year, responsible for the long-term maintenance of this product". This product has been used on hhb-25 mixer of Shaoxing highway maintenance company and slhb-14 mixer of Zhuji highway section for a long time. Recently, it was successfully installed and debugged on ljgq-40 mixer at Hangzhou suburban highway. Interested units or individuals can ask them about the use of the product
