I. Introduction
Boilers, kilns, small smelting furnaces, incinerators and other equipment commonly used in industry, service industry, municipal heating and other fields in various provinces and cities in my country are currently mainly powered by coal, diesel, and fuel oil. Coal-fired fuel seriously pollutes the environment and damages the ecology due to harmful pollutants such as smoke, dust, sulfur dioxide, etc., and is being vigorously rectified by the environmental protection bureaus of major and medium-sized cities. Some cities have begun to forcibly ban it and require replacement with clean fuels such as fuel or gas. In an environment where the world crude oil price is about to soar to US$60 a barrel, my country's refined oil products continue to rise, and energy consumption costs continue to increase, which has put many companies and industries under heavy pressure. Therefore, developing new energy sources and researching energy-saving combustion technologies and equipment have become the central themes of the national energy policy.
The light hydrocarbon semi-automatic energy-saving burner is an alternative technology product to the diesel burner. Using light hydrocarbons as by-products of the petrochemical industry as the main fuel, it can be widely used in combustion equipment such as boilers, kilns, small smelting furnaces, incinerators, annealing furnaces, heating furnaces, and drying furnaces (machines). It is cleaner and more environmentally friendly than burning coal, and it is more energy efficient and saves money than diesel. The development and promotion of light hydrocarbon semi-automatic energy-saving burners and light hydrocarbon fuels in a region is a good project with high return on investment, short construction period and in line with the national policy of environmental protection and energy conservation.
2. Working principle
The light hydrocarbon semi-automatic energy-saving burner is mainly composed of a multi-circulation stainless steel vaporizer, a preheating tank, a micro oil pump, an injection nozzle, a pulse electric igniter, supporting parts and a shell. Light hydrocarbon fuel is filled in large steel cylinders or pressure tanks. Appropriate amount of compressed air is injected into the container for output power. Under the pressure of a micro oil pump, it is injected into the preheating tank and gasifier to be ignited, preheated, gasified, ejected, burned, and mixed. The air is automatically matched according to the speed of the hot gas flow, and does not require a blower to add oxygen. It is easy to install, simple to operate, safe to operate and has a low failure rate.
3. Technical advantages
1. Main technical parameters: heat flow rate CTYJ-418B type 418MJ/h±10% (the heat flow rate can be adjusted according to the load facilities required by the user's combustion equipment), thermal efficiency ≥95% (when running in the equipment), CO in the flue gas ≤Displacement 0.10% (when a=1), SO2≤0.05%(V/V), operating noise ≤85dB, oil pressure in front of the furnace 0.4Mpa±10%.
2. Compare diesel burner burning diesel:
①The thermal efficiency is increased by 40%, the fuel consumption is reduced by 50% (under the same conditions of thermal work), the oil price is about 10% lower, the comprehensive energy saving is 30%, each burner can save 20,000-30,000 yuan in fuel costs per year (based on 300 working days) , 2400 hours calculation).
②Simple structure and low production cost.
The price of a single diesel burner is 6,500 yuan (418MJ/h), and the imported one is more than 10,000 yuan. The factory cost is more than 4,800 yuan each. The price of a single light hydrocarbon semi-automatic energy-saving burner can be less than 3,000 yuan, and the factory cost is less than 600 yuan each. Users save money and manufacturers make money.
③The combustion conditions are better than diesel burners.
When the diesel burner is atomized and burned, the oxygen supplied by the fan can only reach 40% of the combustion oxygen demand. If there is no oxygen fan in the furnace, it will always be in an oxygen-deficient combustion state. The flame will be white and yellow, and the flame temperature will be low (usually 1000 ° C), the CO emission in the flue gas is more than 0.6%, and the unburned CXHX compounds are more than 5%. When the light hydrocarbon semi-automatic burner is gasified and burned, the amount of hot gas injection and automatic oxygen distribution reaches 98% of the combustion oxygen demand. %, the CXHX compound is completely burned, the flame is clear and light blue, the flame temperature can reach about 1300°C, and the CO emission in the flue gas is ≤0.1%, which is 6 times lower than that of a diesel burner.
④ It consumes less electricity, and a single unit can save about 1,500 yuan in electricity bills per year.
The motor of diesel burner is generally 500W/h-1000W/h; the micropump motor of light hydrocarbon semi-automatic burner is 15W/h, and the power consumption is about one-thirtieth of it.
⑤Long service life and low maintenance cost.
In summary, it is more energy-saving, efficient, environmentally friendly and economical than diesel burners, and has broad market prospects. In particular, Zhejiang's copper and aluminum smelting furnaces are the largest in the country, and they are all facing the new situation of coal-fired transformation. Reducing fuel costs while meeting environmental protection standards is the decision-making theme of all enterprise leaders, so they have the advantage of developing this project.
4. Introduction to light hydrocarbons
Light hydrocarbons are by-products of the petrochemical industry. They are produced in oil fields, refineries, ethylene projects, and solvent oil plants across the country. According to the analysis of market price trends since 2004, the average price is 800-1,000 yuan per ton lower than diesel (0#). This situation will not change until light hydrocarbons have no broad uses. Therefore, it provides developers with a good opportunity to promote light hydrocarbon stoves and light hydrocarbon fuels. Light hydrocarbons are liquid at normal temperature and pressure, with a specific gravity of 0.64-0.66. They are highly volatile and sensitive to ambient temperature. The product standard is GB9053-1998. Its saturated vapor pressure is 200Kpa in summer (40℃) and 200Kpa in winter (0℃). 74Kpa, so the test pressure of pressure vessels used for storage, transportation, and packaging should be ≥0.3Mpa. Its hazard regulation number is 63002, which belongs to Class A and B flammable liquids. Distributors should have storage and repackaging conditions and obtain legal qualifications before operating. In terms of safety standard management, our company can provide dealers with a full set of drawings and related technical documents.
Zhejiang Province is located in a prime location in the Yangtze River Delta. Light hydrocarbon resources are supplied by Zhenhai Petrochemical in the province and large state-owned refineries such as Shanghai Jinshan Petrochemical and Nanjing Yangzi Petrochemical in the surrounding areas. They can be imported from the Middle East, Indonesia and other countries at sea. Light hydrocarbon resources are abundant, the consumer market is huge, and there are unlimited business opportunities.
5. Investment scale
The investment scale for developing light hydrocarbon semi-automatic energy-saving burners and light hydrocarbon supply projects can be large or small, and can generally be determined based on the investor's economic strength and the market scope planned to be developed. Here we calculate the investment scale based on the annual output of 1,000 burners and the annual sales of 50,000 tons of light hydrocarbons.
1. The burner factory requires a production workshop of 1000 m2 and an office building of 1000 m2. The non-construction area is 2000 m2, and the total construction investment is about 2.7 million yuan. Production equipment is 500,000 yuan, 100KVA power is 200,000 yuan, one official vehicle is 150,000 yuan, one after-sales service vehicle is 100,000 yuan, and one engineering vehicle is 100,000 yuan. The total investment in fixed assets of the production plant is 3.75 million yuan, and the working capital 2.25 million yuan, a total of 6 million yuan.
