Special composite fuel oil for coal-burning boiler

Abstract

The invention discloses a special composite fuel oil for coal-burning boiler, and relates to the technical field of fuel oil. The fuel oil is prepared by the following steps: preparing the following components in percentage by weight: 30% to 40% of petroleum based hydrogenated heavy oil, 40% to 50% of tar modified washing oil, and 10% to 30% of coked light oil; then preparing the following auxiliary materials in percentage by weight: 0.02 to 0.04% of combustion improver, 0.01 to 0.03% of dispersant, 0.05 to 0.08% of smoke suppressor, 0.02 to 0.05% of coke inhibitor, and 0.02 to 0.03% of corrosion inhibitor, adding the weighed auxiliary materials into oil product at the same time, and mixing at a certain temperature, wherein the total weight percentage is 100%. The thermal value of the obtained oil product is over 9500 kilocalories, and the combustion temperature can reach 1800 to 2200 DEG C. The composite fuel oil has the advantages of high combustion efficiency, few ash impurities, little pollution, safety, stability, high quality, and low price, the entrepreneurs' requirements on coal-burning boiler oil can be fully met, the oil cost is reduced, waste oil products and oil products that heavily pollute the environment are modified, recombined, and utilized, and the nature environment is protected.

Description

Technical field: [0001] The invention relates to a special compound fuel oil for coal-fired boilers, which belongs to the technical field of fuel oil. Background technique: [0002] At present, the boilers of many enterprises use oil-fired boilers, but most of the fuel used is 0# diesel or heavy oil for direct combustion, which greatly increases the production cost, but also has low efficiency, more ash impurities, and great pollution to the environment. , the security is not high. Invention content: [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a special composite fuel oil for coal-fired boilers. [0004] A special compound fuel oil for coal-fired boilers according to the present invention, which comprises 30%-40% of petroleum-based hydrogenated heavy oil, 40%-50% of coal coke modified washing oil, and 10%-30% of coking light oil according to the weight ratio , and then according to the weight ratio, ta...
