The new fuel oil coke SMMVIK European grinding technique is superior

Waste variable gem oil coke powder is an ideal fuel for industrial kilns

Petroleum coke powder is prepared from petroleum coke as the main raw material through synthesis and deep processing, which can be used as fuel instead of oil. Petroleum coke is a kind of non polar hydrocarbon with porous structure, belonging to hydrophobic substances. Petroleum coke is the end product of petroleum family, which has both physical properties and thermal properties of petroleum. Petroleum coke powder of certain specification is made from petroleum coke through primary crushing, drying and strong grinding process. It is continuously, evenly and stably injected into the furnace for combustion through the conveying system. The generated high heat effectively melts the materials in the kiln to produce various products that meet the quality requirements.

As a solid fuel, petroleum coke powder enters the kiln in high-speed turbulent flow after good atomization. Under high temperature, it is rapidly heated to the ignition point through radiation and convection for combustion and heat release. The calorific value of petroleum coke powder is up to 8500~9000 kcal, the combustion point is 500 ℃~700, and the combustion temperature can reach 1500 ℃~1800 ℃. There is no volatile component in the combustion process and the residue after combustion is basically zero. It is an ideal urban fuel and an economic fuel for energy conservation, emission reduction and environmental protection.

The prospect of petroleum coke powder replacing traditional fuel under market economy is good

The technology of using petroleum coke powder as fuel began in 2007. At that time, petroleum coke powder was only mixed with heavy oil in a certain proportion for combustion. Since 2009, petroleum coke powder has completely replaced heavy oil for direct combustion. At present, it is a relatively mature technology to replace oil with petroleum coke powder for energy conservation. A new fuel system has been developed for industrial kilns, especially for the glass industry, and has been successfully promoted in the glass industry.

According to statistics, replacing heavy oil with petroleum coke powder as fuel can save 42.5% of fuel cost for enterprises every day. Therefore, its economic benefits are very considerable. Therefore, the project is easily accepted by the market. In addition to glass kilns, frit kilns, forging kilns, annealing kilns, crucible kilns, aluminum melting furnaces, industrial boilers and other thermal equipment using heavy oil as fuel can all use petroleum powder as fuel to replace heavy oil after a certain technical design. Petroleum coke powder has considerable promotion value in these industries. If the heavy oil of these enterprises is replaced by petroleum coke powder, a large amount of fuel cost will be saved for these enterprises.

SMMVIK European version grinding machine is better at processing petroleum coke powder

SMMVIK technology has accumulated a lot of experience in the field of processing petroleum coke powder. Customers who use SMMVIK European version grinding to process petroleum coke powder are all over Henan, Shandong, Zhejiang, Guangdong, Sichuan and other places.

MTW series European trapezoidal mill is a new type of mill designed by SMMVIK technology with great concentration. The European version trapezoidal mill adopts a number of new patented technologies, such as bevel gear integral transmission, internal thin oil lubrication system, and arc air duct, which greatly improve the working efficiency and grinding stability. At the same time, it highlights the advantages of energy conservation and environmental protection of the mill, providing technical support for customers to reduce operating costs and improve profits. In particular, in the field of petroleum coke processing, the SMMVIK European version of the grinder is more advanced and has the following innovative advantages:

1. In view of the characteristics of heavy and light petroleum coke, which is not easy to form a powder abrasive layer, SMMVIK optimizes the host grinding device and blade structure, and adopts cage turbine classifier, special flow field design and constant gas-solid concentration control technology, so that the finished petroleum coke powder has uniform particle size, narrow distribution, no large particles, and can ensure that the system can operate stably for a long time, thus increasing the output.

2 .SMMVIK combines its own experience in coal powder and other industries. Since petroleum coke is a fuel, it is dangerous to some extent, so explosion relief devices are set on the equipment to improve the safety of the equipment.

3.The whole machine is operated under totally enclosed negative pressure, with clean production environment, no dust pollution, and dust emission less than 30mg/m3, which fully meets the national environmental protection requirements.

4.The new offline ash removal technology of the United States is adopted for the dust remover, which effectively ensures the ash removal effect. The cloth bag is an oil repellent and hydrophobic membrane filter bag (applicable to the powder with strong adhesion, such as petroleum coke), and the filter area of the dust remover is increased. The powder adhesion on the cloth bag is small, which ensures the long-term stable operation of the system.
