A kind of environment-friendly biological fuel oil for boiler and preparation method thereof

Abstract

The invention relates to an environmentally-friendly biofuel for a boiler and a preparation method thereof. The fuel is high in calorific value, easy to ignite, strong in firepower, low in sulfur content and small in corrosion on combustion equipment to prolong the service life of the boiler; the fuel is high in oxygen content, thereby being easily forming oxygen enriched combustion and improving the combustion efficiency; the fuel is low in viscosity, good in fluidity, free of pre-heating when in use, easy to atomize, small in atomization particles, good in atomization, complete in combustion and unlikely to coke, and little accumulated ash is generated, thereby reducing the accumulated carbon and attrition and preventing the nozzle from being easily blocked; the fuel is uniform in atomization and balanced in combustion so as to improve the combustion environment and reduce the nitrogen oxide generation; and the fuel is complete in combustion, small in pollutant emission, small in air pollution and good in environmental protection effect. The biofuel can be used for saving and replacing such traditional fossil energy sources as mineral fuel and high-pollution fuel, thereby being a clean and environmentally-friendly biofuel.

Problems solved by technology

[0008] Fuel has high viscosity, poor fluidity and difficult atomization

Difficult atomization and large atomized particles lead to incomplete combustion, lower thermal efficiency of the boiler, formation of carbon deposits, and easy blockage of fuel injectors; uneven distribution of fuel oil due to atomization leads to local high temperature and high pressure in the boiler combustion chamber, and unbalanced combustion. Affect the operation of the boiler

[0009] The oxygen content of fuel oil is low. Due to poor atomization, the oxygen supply during combustion is insufficient. Oxygen-deficient combustion leads to insufficient combustion, resulting in a large amount of carbon particles and oil droplets accumulating on the heating surface at the rear of the boiler, forming unsafe combustion and emitting black smoke.

[0010] Fuel oil contains non-hydrocarbons, colloids, asphaltene, sulfides, and nitrogens. Due to incomplete combustion, the content of pollutants in the combustion exhaust gas increases, the harmful components increase, and the dust particles increase.

[0011] Fuel combustion waste gas emissions exceeding the environmental protection limit will cause air pollution, form smog weather, reduce air quality, seriously pollute the environment, and seriously affect people's public health and social stability
